Real Driving Emissions
Opis:
In the assumptions, regarding to the transport policy both at the level of country and Europe there is the concept of sustainable development of transport. Warsaw University of Technology in cooperation with Poznan University of Technology performs research work concerning the shaping of environmentally friendly transport system – Project EMITRANSYS. In this project, one of the conditions is to reduce exhaust emissions by means of transport. The paper presents the reasons for the testing of the exhaust emissions under Real Driving Emissions testing (RDE). Research potential of Institute of Combustion Engines and Transport at Poznan University of Technology in the area of road testing of passenger and heavy-duty vehicles has been presented in the paper. Example test results have been shown in the aspect of the emission-related classification of vehicles. The major challenge of worldwide emission standards, engine operating parameters in various emissions tests, the test potential under real operating conditions, the view of the analyser for on-road emission testing of vehicles, the test results for road emission of CO, HC and NOx, detailed characteristics of the averaged particle number for the entire test run (vehicles with different mileage and different emission class) for: Euro 4 class and 75,000 km; Euro 4 class and 500,000 km; Euro 5 class and 75,000 km; Euro 5 class and 500,000 km are presented in the paper.

Opis:
Article presents the results of fuel consumption calculation during cruise compared to remaining aircraft flight phases. Based on fuel consumption, methodology of pollutants quantitative estimation emitted by turbine engines has been developed. Material provides evaluation results of aircraft CO2, CO and NOx effusion using fuel consumption data taken from aircraft Flight Data Recorder (FDR) during cruise of various aircraft types. Knowledge of the amount of aircraft emissions on high altitudes is very important for climatologists in order to understand eventual changes in the Earth atmosphere due to aviation activities. The authors would like to draw attention of the aviation professionals to the fact that aircraft fuel consumption during cruise; thereby amount of toxic content in the exhaust from the turbine engine is significantly higher especially during flights against jet stream. Thousands flights of two operators were processed using algorithms developed by authors. The article gives an example of fuel consumption and thereby CO2, CO and NOx emission estimation based on engine performance taken from their test cell results. Calculations were performed with the consideration of the factor for engines deterioration through operation time provided by its manufacturer.

Opis:
Due to the legal changes in the exhaust emission limits in the European Union meeting the new norms becomes more challenging for car manufacturers. The recent progress in the exhaust aftertreatment technology and commercially available aftertreatment systems. However, as the exhaust, systems become more and more complex the problem of high emissions in many engine-operating points that are not currently a part of the type approval tests remains. The article aims to address the limitations of the oxidation catalysts in current aftertreatment systems, mainly their light-off temperature, by investigating new options for in-cylinder catalysts. Placing the catalytic layer within the combustion chamber avoids a number of problems associated with these catalysts being a part of the aftertreatment system. Engine emission tests have been performed comparing the effects of using an in-cylinder Pt-Rh catalytic layer in relation to hydrocarbon and nitrogen oxides emissions. The viable methods of producing a catalytic layer on engine components along with the choice of components to use for catalytic surfaces have also been discussed.

Real Driving Emissions
Opis:
This paper presents the results of tests conducted in real traffic conditions in a mountainous area, taking into account the natural topography characteristics. The tested vehicle was of SUV type (Sport Utility Vehicle) with gasoline and Diesel engine, complying with emission standard Euro 5. Using the portable system for measurement of harmful substances, measurements of pollution emissions were conducted. The results obtained confirmed the substantial changes in the emission of harmful components of exhaust fumes with the change of the road grade. In all considered cases, it was confirmed that with the increasing route grade, the road emissions of all harmful components of exhaust fumes increase, however this increase varies for different pollutants. The most sensitive for spark ignition engines is emission of particulate matter, which is associated mainly with the compression ignition engines. For small changes of the road grade, the most sensitive seems to be road emission of carbon monoxide, for gasoline engines emission of particulate matter is specific, first, to all diesel engines, increase of the road grade to 10% caused on average twofold increase in the emission of harmful components of exhaust gases.

An object of the paper is development process of on-board systems diagnostic which can be divided into the historic phase (defined as OBD I), the present term - OBD II and OBD III, and the destination regulation. Established OBD II requirements use allowable the driving emission level limits of the FTP test, however its European EOBD equivalent, effective in Poland, uses limits (together with suitable coefficients of the enlargement) in the NEDC (New European Driving Cycle) test. The research programme of homologation is based on standard driving cycles of characteristic courses of the speed. Conditions of the realization of procedures are selected, so that their meeting in driving cycle is confident and so that its realization secures the correct result. Results of the procedure are illustrated with the original coefficient of the cover of the cycle time by found similar fragments driving cycles. In particular inter alia main criteria of damages according to Californians' CARB OBD II regulations, vehicle performance record during FTP75 test on chassis dynamometer, implementation of oxygen sensor monitor marked with vertical line, RPM, engine loading, engine temperature, speed, NEDC (UDC + EUDC) driving test, temperature chamber and chassis dynamometer stand control devices, dilution exhaust gases device, exhaust gases analyzers are presented in the paper.

Opis:
The article compares driving test data using the latest legislative proposals applicable to passenger cars. Real Driving Emissions procedures have been introduced in the Commission Regulation (EU) 2016/427. Currently, quantitative RDE requirements have been established to limit emissions from exhaust systems in all operating conditions in accordance with the road emission limits set out in Regulation (EC) No. 715/2007. Several measurements were performed on the same test route in accordance with the RDE test guidelines, which requires a number of criteria to be met. These criteria include the length of the measuring segments, their overall test timeshare, and the dynamic characteristics of the drive. A mobile device for reading the EOBD System information was used to record the engine and vehicle operating parameters during tests. This allowed for the monitoring of parameters such as: load value, engine speed and vehicle velocity. The obtained results were then analysed for their compatibility with the RDE procedure requirements. Despite the same research route, the obtained results were not the same. The analysis also uses the two-dimensional operating time-share characteristics expressed in vehicle velocity and acceleration co-ordinates. As a result, it was possible to compare the dynamic properties, share of operating time and, consequently, to check the validity of conducted drive tests in terms of their practicability and emission values.

The paper presents selected aspects of a design of a proecological transport system. The necessity of designing proecological transport systems results from forecasts of transport demand and adaptation of the infrastructure to the standards and requirements of the EU. The European Commission pays special attention to the need for sustainable and environmentally friendly transport. Warsaw University of Technology in collaboration with Poznan University of Technology performs a research work concerning the development of an environmentally friendly transport system - Project EMITRANSYS. One of its stages is a development of a mathematical model taking into account the minimization of both the negative impact of transport on the environment and the transportation costs. The paper proposes a general formulation of the mathematical model of a proecological transport system (MEST) including the boundary conditions. A function of criterion minimizes the emission of harmful exhaust components resulting from traffic distribution in a network. The point elements of the infrastructure in a model represent places where the infrastructure parameters change, i.e. crossroads, narrowed roads or reduced speed areas. In addition, the structure of the vehicle fleet embraces the characteristics of the emission levels of different types of exhaust components.

The results of comparative research of the organie components in the exhaust emissions of the CI engine fuelled with Diesel oil or rape seed methyl esters (RSME) were presented in this paper. The experimental works reported here was carriedout on the turbocharged, four cylinder, water cooled, CI engine, T 370 type (80 kW rated power at 2400 rpm, 400 Nm maximum torque at 1440 rpm, bore/stroke - 110/120 mm, displacement volume - 4560 cm3, compression ratio 17:1). The Signal equipment and AVL eeuipment were used for regulated exhaust emissions measurements and Hewlett Packard chromatograph type HP 5890 H for measurements of organic species emissions. The research was carried out under engine full load at maximum torque speed and at rated power speed. Using special equipment and normalized procedures the chromatographic test samples were collected. The 83 species were identified in HC emissions at these experiments but only the benzene, toluene and acetaldehyde were the components which were detected in substantial guantity. The research results show that the percentage emissions of individual components in total emissions of HC were weakly dependent on the used fuel. However in the case of RSME engine feed the HC emissions were lower than hose of the engine fuelled with Diesel oil and total emissions of their components were lower. Concluding, emissions from RSME combustion are less harmful than emissions of the engine fuelled with Diesel oil.

Today, more and more attention is paid to search for alternative fuels, which would be not only environmentally friendly, but also cost-competitive to petroleum fuels. In the recent years much attention is paid to investigations at adaptation of combustion engine to run on bio-fuels. Results of the investigations show, that methyl and ethyl alcohols could belong to one from the most promising and future bio-fuels, being a serious alternative to petroleum fuels. Interest in these fuels comprises such areas as exploration of raw materials to production of the alcohols, development of technology of their production, especially 2nd generation of ethyl alcohol, special fuelling and control systems, design changes of the engines fuelled with alcohols. In the present paper are shown test results of Fiat 1.3 Multipoint engine fuelled in dual fuel system with methanol and gasoline. In this engine one assembled prototype fuel supply system with duplex injectors on each cylinder, to injection of methanol and gasoline. Implemented system enables fuelling with gasoline only, with methanol only, or simultaneously with gasoline and methanol with any fraction of the methanol. Change of fuelling system and change of methanol fraction can be accomplished in course of engine operation. Performed investigations showed advantageous effect of the methanol on toxicity of exhaust gases. One confirmed reduction of emissions of hydrocarbons, nitrogen oxide and carbon dioxide. The biggest changes in the concentration occurred in case of fuelling with the methanol only, and amounted to: 2-3 times reduction of the THC, reduction of NOx with 40-60%. Differences in concentration of NOx increased together with growth of engine load, and hence, they concern such areas of engine operation, where the biggest quantities of the NOx are emitted. In case of dual fuel feeding, effect of reduction of concentration of the components discussed here decreases according to reduced fraction of the methanol. Changes in the emissions discussed here are obtained with maintained engine performance and growth of overall efficiency of the engine. Implemented system eliminates problems of stratification of methanol-gasoline mixture in low temperatures and in presence of water. The system can be adapted to any liquid fuels.

Opis:
There is a tendency to increase the economic efficiency of engine operation and energy efficiency and reduce emissions of toxic combustion products. One way to reduce emissions of toxic components in exhaust gases is raising the coolant boiling point, which requires the simultaneous increase in pressure in the cooling system. Previous studies suggest that such a system can reduce the amount of toxic components in exhaust gases, particularly at low engine load when the engine exhaust temperature is too low to make effective catalytic action. The paper presents the model and experimental test stands to research the cooling system at an elevated temperature of the coolant. The speed and load characteristics of the standard cooling systems and pressure were presented. The research results were designed to determine the effect of elevated temperature in the cooling system on the composition of the gases. The characteristics of the external speed and load were performed with standard cooling systems and pressure. When performing velocity characteristics of the engine was loaded up in the whole range of engine speed from 1000 to 4000 rev/min, while the load characteristics were performed for different values of torque at constant speed in the range from 1500-4000 rpm. The results confirmed the benefits of increasing the temperature of the coolant. The presented characteristics that apply pressure cooling system reduces the amount of toxic components in exhaust gases, particularly at low engine load, in which the engine operates most often in urban conditions.

Opis:
In 2015, the number of vehicles in the world exceeded 1.1 billion units. In the coming years, it is expected that the largest increase in the number of vehicles will take place in developing countries. This is a problem in particular in terms of emissions of harmful substances from vehicles. Considering that all manufactured vehicle models have to undergo a detailed homologation and meet the exhaust emission requirements before placing on the market, it is necessary to refine test procedures, including test cycles, in which vehicle emissions are determined. At present, the NEDC approval test is valid in Europe. It is a cycle reproduced on a chassis dynamometer in steady conditions. It consists of an urban section repeated four times and an extra urban part. From 2019, a new test procedure will take effect, which uses the WLTC cycle, also reproduced on a chassis dynamometer in fixed conditions. It is much more complex and better reflects the real traffic conditions. For a better illustration of the differences that occur between the current NEDC cycle and the new WLTC, the article presents a comparative analysis of both driving cycles. This is to present the justifiability of using a new driving cycle and to present its complexity. The article presents own research of a vehicle with a spark-ignition engine, which has been tested both in the NEDC and WLTC cycle. On the basis of the obtained data, it was possible to determine the differences in the emission of harmful exhaust gas components and indicate how the new homologation procedure affects the emissions from the vehicle.

The article presents bench test results of a four-stroke, four-cylinder, naturally aspirated, DI diesel engine operating with neat JP-8 fuel (J) and its blends with Diesel fuel (D) in following proportions by volume: 90/10 (J+10D), 70/30 (J+D30), 50/ 50 (J+D50), 30/70 (J+D70), and 100% diesel fuel (DF). The purpose of the research was to analyse and compare changes occurred in the autoignition delay, combustion events, engine performance efficiency, emissions, and smoke of the exhaust when running on JP-8 fuel, jet-diesel fuel blends, and diesel fuel at a full (100%) engine load and speed of 1400 min–1 at which maximum torque occurs and rated speed of 2200 min–1. It was found that the start of injection (SOI) and the start of combustion (SOC) occurred earlier in an engine cycle and the autoignition delay decreased by 9.0% and 12.7% due to replacement of aviation JP-8 fuel with diesel fuel at a full load and the latter speeds. Maximum in-cylinder pressure was 6.8% and 4.0% higher when operating with diesel fuel, whereas brake thermal efficiency was 3.3% and 7.7% higher, and brake specific fuel consumption 2.8% and 7.0% lower when using fuel blend J+D50 compared with the respective values measured with neat JP-8 fuel. Emissions of nitric oxide (NO) and nitrogen oxides (NOx) were 13.3% and 13.1% higher from a straight diesel running at speed of 1400 min–1, and 19.0% and 19.5% higher at a higher speed of 2200 min–1. The carbon monoxide (CO) emissions and total unburned hydrocarbons (HC) decreased 2.1 times and by 12.3% when running with fuel blend J+D70 at speed of 2200 min–1 compared with those values measured with jet fuel. Smoke of the exhaust was 53.1% and 1.9% higher when using fuel blend J+D10 than that of 46.9% and 70.0% measured with jet fuel at speeds of 1400 and 2200 min–1. The engine produced 34.5% more smoke from combustion of fuel blend J+D70 at the low speed of 1400 min–1, but smoke converted to be 11.3% lower when operating at a higher speed of 2200 min–1.

The article presents the results of the of the HC emissions composition for the compression ignition - diesel engine fuelled with rapeseed fuel (a mixture of methyl esters of fatty acids - RSME). The investigations were conducted on a turbocharged, four-cylinder compression-ignition engine type T370 (of 80 hW power at 2400 rpm engine speed and maximum torque of 400 Nm at 1440 rpm engine speed, with bore/stroke 110 mm /l20 mm, displacement volume 4560 cm3, compression ratio 17). For the exhaust toxicity investigations the eauipment of Signal and AVL companies was used, and for composition of nonregulated hydrocarbons emissions investigations the Hewlett Packard Company chromatograph type HP-5890II was used. The investigations were conducted under engine full load at maximum torque speed and for engine rotational speed of the rated power. Chromatographic test for emissions were collected using special equipment and special procedures. The article presents the results of chromatographic investigations focusedon: benzene, toluene and acetaldehyde. It was found that the percentage of emission of individual components in the total emissions of HC was independent of the fuel used. However, due to the fact that in the case of rape fuel, emission of unburned HC was smaller and smaller were the absolute amounts of emissions components. Thus, emissions from combustion of rape fuel are less harmful than emissions from the engine fuelled with diesel oil.
