Opis:: Currently produced diesel engines of different manufacturers, used for the same applications, have comparable specific fuel consumption. Therefore, the laboratories measuring fuel consumption, especially in comparative tests, require the use of more accurate methods of measurement. The Environmental Protection Centre of Motor Transport Institute has recently implemented the fuel consumption measurement method using KMA Mobile flow meter produced by AVL company. This device allows to carry out measurements by both volumetric and mass method, thanks to builtin device for measuring the fuel density. Due to some customers requirements the laboratory began with preparations for obtaining accreditation of the Polish Centre of Accreditation for the procedure of measuring fuel consumption by volumetric and mass method. One of the requirements of the Polish Centre for Accreditation is carrying out the validation of the new method. It can be done by comparing the results obtained with new method with the results of the method already validated. The validated method is described in the regulation. This is the carbon balance method described in UN-ECE Regulations No. 101. The calculation of fuel consumption according to this method is based on a measurement of pollutants emissions of carbon dioxide (CO2), carbon monoxide (CO) and hydrocarbons (THC). This paper describes the fuel consumptions measuring procedure using two methods: mass method using a AVL KMA Mobile flow meter and carbon balance method using the AVL AMA i60 analyzers. To verify measurement results additionally there was fuel consumption measured with using a scale, as a difference of the external fuel tank mass change, from which the vehicle was fuelled during the tests

Opis:: A theory of cumulated fuel consumption in process ofvehicle operation is described. The method of creation the mathematical model and procedure of determination of model variables is shown. The mainfeatures of cumulated fuel consumption are painted attention. li is shown that the theory of cumulated fuel consumption can be use to description of the fuel consumption from beginning the exploitation of vehicles and also for the situation when the vehicle are in exploitation from any time and further fuel consumption are unknown. An example of utilisation of elaborated theory for assessment of operation of passenger car is also presented. It has been shown that applying the theory of cumulated fuel consumption, the course of such consumption can be accurately described also in this case. This proposal can be formulated in spite of making some simplifications. This is because the unknown value of the accumulated fuel before start the time of observation operation will be determined using the average (from the average) fuel consumption. This simplification greatly facilitates the flow of the calculations and it seems does not offend errors in the calculations. Method of determining the average is discussed in the article. It appears that such treatment may be justified by the fact that the mistake is, in principle, systematic error. Very high coefficients of mathematical model to fit the measured data are very interesting. Such regularity was observed during researches in buses transport [l], intercity buses, and the fleets of various vehicles (the results of researches are not yet published).The introduction of the theory of cumulated fuel consumption as one of the important parameters to assess the operation of the vehicle or vehicles may also be useful in exploitation researches. At present times the researches in which the vehicles are already in service and the engine control mops are tuned (chip tuning), are made. A good performance of these changes is often observed on chassis dyno but that is not properly sanctioned in natural exploitation. Experimentation with such issue is underway and will be the subject of future analysis (and publications).

Opis:: Theory of cumulative fuel consumption is shown for the first time in [1] and [2]. The theory of cumulative fuel consumption has been presented also in this work. The example of LPG car research results have shown the way of getting to mathematical model of cumulative fuel consumption and the intensity of cumulative fuel consumption. In this case, the studies were carried out 16 cars whose engines were powered by LPG. The vehicles are operated in a small fleet of vehicles, which run in city traffic. Data on outcomes of exploitation and operation fuel consumption is acquired from the accounting documents of the company. Very good results prediction mathematical model of operational data are obtained. The high value of prescience quotients (in this case R-sq > 9.999) are similar to the values that were obtained in various other cases. Conversance of mathematical model of cumulative fuel consumption allows carrying out comprehensive analysis of this significant exploitative parameter. The presented theory must not only be regarded as a theory of cumulative fuel consumption but also can be seen more broadly as a theory of cumulative energy consumption. Research is being conducted on the application of the theory to evaluate energy consumption by hybrid vehicles. The results can be very interesting.

Opis:: In the automotive industry in the world continuously being sought universal driving cycle. The test should closely match the fuel consumption and emissions of toxins in the fumes of the test vehicle in its real operating conditions [4]. However, in the previously developed solid driving tests established velocity profiles differ significantly from actual driving conditions. The difference in fuel consumption, comparing the natural operation of the NEDC test reaches an average of 18%. The new version of the driving cycle should be more realistic to the everyday use of additional equipment and gadgets that are installed in modern vehicles [1]. The impact on fuel consumption by vehicles may be conditioned not only by its size and weight, but also by the geometry of the track motion, forces causing the motion and the forces acting on the car when driving on curved tracks. The vehicle encounters and overcomes all the forces that act on it while driving-resistance movement. In the energy intake through the vehicle runs in the motor changes at the expense of the energy of fuel consumed. The driving force performs work on a given stretch of road balancing (predominant) friction. On the basis of the calculated resistance movement and the energy consumption of the movement in the selected object was a comparison of the actual consumption of fuel in the vehicle with the ignition spark. Analysis was performed and found differences in three cycles: urban, extra-urban and combined.

Opis:: The study presents a draft calculation of fuel consumption and emission of CO2, CO, HC and NOx by a engine car used in real traffic conditions. In this project, the author was inspired by the results of his own studies and those of selected domestic and foreign research centres. The (static) engine performance maps including Brake Specific Fuel Consumption maps, ge (CO2), and maps of speciftc emission of CO, HC and NOX,, serve as the basis for this study. Underlying such an approach are the disparate courses offuel consumption and emission levels in the driving and non-driving modes of the engine. For the study purposes, an adeąuate testing programme should be implemented, using a variable driving cycle [1]. A departure from the homologation cycles applied to this end allows covering, on an engine performance map, the area of engine operation being of interest to us with measuring points. For calculations in operational conditions, the maps of changes of Delta ge, Delta CO2, Delta CO, Delta HC and Delta NOX for nonstationary operating conditions of the engine will be a complement to static engine performance maps. The author has already developed partial maps for the first two parameters. The development of the others requires the implementation of a costly research scheme in cooperation with a leading domestic research centre.

Opis:: Development of road transport is now subjected to numerous constraints related to reachability exhaustive sources of liquid fuels and the associated increase in their prices. In addition, restrictions on emissions tend for quickly change the drives with an internal combustion powered petroleum products for electric cars in the near future. Compared to the conventional internal combustion engine, full electric cars driven on European roads appear as environmental winners for the next decades in terms of environmental protection.The article draws attention to the growing increase in CO2 emissions over the years until 2050.Forecasts by 2050, it is estimated that environmentally friendly vehicles will probably reduce the CO2 emissions into the atmosphere comes from cars.The article shows that the speaking of electric vehicles in terms of ecology should take into account the emissivity of the vehicle together to produce a current, and not only the emission of the vehicle from tan to wheel. In the article dealt with directions of development electric sector model in the context of the year 2050. It presents three scenarios that involve the reduction of CO2 emissions, which directly translates into lower fuel consumption.

Opis:: Measuring method and calculations of the impact of non-stationary work conditions of car engine torque load upon its effective efficiency have been presented in the paper. The obtained results have been compared to the already achieved results. The applied method of calculation balance and the consumed fuel enabled the writer of the paper to calculate the value of the change of unitary fuel consumption at a work point on engine performance map. The carried out examinations focus on measurements at one measuring length and so the rate of torque load at each of the four gear box ratio (2-5) can be controlled by constant final velocity of driving or by shifting or extending the measuring length against the lowest point ( the measuring length is 'U'-shaped). Finding the right solution to this problem will allow elaborating the calculation algorithm of engine effective efficiency for the examined range of engine performance maps for changeable, non-stationary work conditions. The results make it ąuite explicit that non-stationary work conditions from the engine speed and the engine load impair the effective efficiency of the engine at work in particular gears. Non-stationary mode of engine operation is essential for the higher values of gear box ratio whereas for lower values the engine load really matters.

Opis:: In this paper is presented a calculation procedure based on Lagrange's interpolation formuła which has been used for describing the external characteristics of compression-ignition engine of the 359 type. The characteristic curves of specific fuel consumption and exhaust gas smokiness were chosen as an example, which had been obtained during examinations on engine test bed for a drive unitfuelled with four types of fuel. Measurements were carried out on a standard engine test bed which is part of laboratory facilities of the Department of Automotive Vehicles Operation, Western Pomeranian University of Technology in Szczecin. The study object was an unsupercharged four-stroke engine of domestic production of the 359 type. It is a six-cylinder compression-ignition drive unit with direct fuel injection system. Interpolating polynomials determined analytically for respective characteristics have been presented in the graphical form, while experimental examination results necessary for obtaining them have been additionally tabulated. The presented methodology allows simplification of particular experiment stages by giving possibility to estimate analytically the missing data and with preservation of a minimum number of measuring points. With small corrections, it may be used in similar examinations on other engine test beds. Its application should support the planning of particular experiment stages but does not, in any case, replace it since determination of engine characteristic curves is possible through research only.

LPG fuel consumption
Opis:: In research of LPG fuelling engine, often used method of fuel consumption measurement is weighing of fuel tank. This method is not proper for fuelling system with fuel pump located in the tank. When LPG pump is working are generated vibration that introduce significant disturbance of fuel tank mass measurement. For test bed research of liquid LPG fuelling engine with sequential injection system (system of V generation), measurement of fuel consumption is very difficult because there are fuel vaporization problems in the fuel pipes, too. This paper presents LPG measurement system, with two of mass flow meters in differential configuration, proposed by authors. This system allow for accurate measurement of LPG fuel consumption. The described system was used for MD-111E engine in test bench research. This engine was fuelling with liquid phase sequential injection system into the suction manifold. Significant problem in the liquid phase injection system is the measuring of fuel consumption. This required of LPG pump installed of the proper rate of delivery to reduce vaporization of fuel. Average relative difference of measured fuel consumption per hour SGt,, for location of flowmeter sensors in the injectors circuit did not exceeded 2%.

Opis:: Combustion in a diesel engine is a complex physicochemical process, changing the time at which the events take place simultaneously heat and mass transfer and chemical reactions. The development of internal combustion engines goes towards meeting the increasingly stringent requirements for toxic exhaust emissions, reducing fuel consumption and therefore reduce carbon emissions and protect the Earth's natural resources. The problem to solve in modern combustion engines is the emission of NOx. One way to reduce the emission of toxic NOx combustion engine power is water-hydrocarbon emulsions [1]. Research combustion engines water-hydrocarbon emulsions has been its tradition. So far, attempts were carried out using an emulsion obtained by a chemical. Emulsions of oil and water can be obtained by adding various detergents to prevent delamination of the oil and water. In this article, we consider the possibility of applying a mixture of water and oil as an alternative fuel used to power internal combustion engines used in heavy road transport. This work is preliminary work, also having to check whether this is the future direction of the work. The measurements of emissions of exhaust gases and fuel consumption. After analysing the test results confirmed that the improvement of the economic and environmental performance of modern diesel engines, it can be achieved by supplying synthetic diesel or gas oil water emulsions. It was found that the use of emulsion leads to a reduction of fuel consumption and NOx emissions.

Opis:: The article presents experimental research that has been carried out on a marine, 4-stroke, 3-cylinder, turbocharged engine. During testing, the engine operated at a constant rotational speed of 750 rpm and a load from 0 kW to 280 kW. The engine was fuelled by diesel oil of known specification and loaded by electric generator with water resistance. The fuel consumption was measured during the engine operation with fuel nozzles with different geometries. The measurement of the fuel consumption was carried out using a weighing system that was designed, constructed, and manufactured by the “KAIZEN” scientific research team at the Faculty of Mechanical Engineering at the Gdynia Maritime University. The results of measurements show changes in the fuel consumption by the engine with the geometry of the injected fuel spray. The research facility is Sulzer’s 3- cylinder, 4-stroke, turbocharged AL25/30 piston engine. The fuel system consists of Bosch injection pumps controlled by a rotation speed regulator. Fuel injectors are centrally located in the cylinder heads of the engine.

Opis:: The goal of the paper is to focus the problem of emission of toxic compounds e.g. NOx, SOx and CO2 from seagoing ships to environment. The VI Amendment to Marpol Convention concerning prevention against air pollution by seagoing ships brought into practice in May 19th 2005 forced ship owners to use means for reduction of environment harmful substances emission to atmosphere. Considerable reduction of these harmful substances can be use dual fuel diesel engines for ship propulsion. Dual fuel engines are fuelled by natural gas having methane as main component. Leading producers of marine diesel engines introduced into production diesel engines DF (Dual Fuel) type. These engines can be fuelled alternatively with natural gas or with heavy fuel oil and marine diesel oil. Today the propulsion by diesel engines fuelled with natural gas is the most popular on ships carrying natural gas cargo i.e. LNG carriers (Liquefied Natural Gas Carriers). Natural gas is freight in liquid form under atmospheric pressure in temperature -163 °C. Due to heat penetration into cargo tanks, the liquefied gas evaporates. Evaporated cargo BOF (Boil Off Gas) is used as a fuel in ship diesel engines. However, dual fuel engines are used on other types of ships not only on LNG carriers. A number of seagoing ships fuelled with natural gas are now under construction. For example container ship 9,000 TEU in Japan shipyard Kawasaki Heavy Industries or container ship 14,000 TEU in Korean shipyard Daewoo Shipbuilding & Marine Engineering for company CMA-CGM. Ships fuelled with natural gas e.g. modern ferries are also built by Stocznia Remontowa Shipbuilding in Poland for Norwegian owner. Adaptation of presently operated ships for fuelling with natural gas is also considered.

Opis:: This paper presents the simulation analysis determining the effect of wheel outer diameter and energy efficiency class of tire on fuel consumption of a passenger car. Calculations were made assuming the wheel movement on a dry, smooth road surface under set driving conditions. Tests objects were three tyre types of the following sizes: 155/80R13, 165/65R14 and 185/55R14 (provided by the manufacturer of a FIAT Panda vehicle). For testing, a simulation model was used allowing for tyre construction parameters (outer diameter and energy efficiency class). Different values of rolling resistance coefficient were adopted (in accordance with energy efficiency classes) and the values of basic resistance to motion (therefore the sums of rolling resistance and air resistance) were determined for vehicle speeds equal to 15 km/h, 32 km/h, 35 km/h and 50 km/h (being the components of UDC speed profile) and for 70 km/h, 100 km/h and 120 km/h (being the components of EUDC speed profile). Based on the parameters describing a vehicle, motion conditions and tyre sizes, the values of engine rotational speed and load torque were determined. For these parameters, the values of mileage fuel consumption were read. Based on the conducted analysis, it was concluded that fuel consumption for a set vehicle speed was little affected by wheel outer diameter but significantly affected by tyre energy efficiency class. The increase of wheel outer diameter (in accordance with manufacturer’s information) induced a small decrease in fuel consumption. The use of high-energy efficiency class (A), in relation to lowest efficiency class (G), allowed the fuel economy even to a dozen or so percent.

Opis:: The subject of paper is to focus the problem of carbon dioxide emission from seagoing ships. The paper presents analysis of possibilities of fuel consumption minimizing and this way reduction of carbon dioxide emission from seagoing ships. However, The VI Amendment to MARPOL Convention concerning prevention against air pollution by seagoing ships did not take into consideration carbon dioxide emission, the importance of this problem was perceived by international organizations among others by IMO. As a result corrections in VI Amendment to MARPOL Convention were introduced thus forcing reduction of CO2 emission by seagoing ships. Among means reducing emission of carbon dioxide into atmosphere the following are mentioned: construction modifications of new built ships i.e. reduction of ship speed, optimization of main engine and propeller selection, optimization of ship hull shape, application of resistance reducing hull coatings, use of alternative (ecological) fuels and utilization of propulsion plant waste heat. In turn, for ships already in operation methods for fuel consumption and carbon dioxide reduction can be individual for each ship full monitoring of main engine operational parameters and measurement of waste heat utilization rate. According to opinion of paper authors, the minimizing of carbon dioxide reduction can be mainly achieved by utilisation of exhaust gases heat for electric power production in steam turbo alternators running in one- or two stage steam pressure systems. The analysis executed in the paper of one- and two stage steam system advantages shows that one stage steam system is more economically profitable in practice application.
