Opis:
The objective of the present study was to experimentally investigate environmental emissions and performance of a stationary type diesel engine fuelled with biodiesels derived from two different feedstocks; one is more unsaturated (rice bran biodiesel) and the other one is more saturated in nature (palm biodiesel) and compare with petrodiesel. Tests were conducted in a single cylinder, air cooled, direct injection diesel engine. From the experimental results, it was found that the nitrogen oxides emissions were higher with biodiesel fuels. The hydrocarbon and carbon monoxide emissions of palm biodiesel were lower than the other test fuels. The smoke emission of rice bran biodiesel was the lowest compared to the rest of the fuels. A considerable reduction in thermal efficiency was found with both the biodiesels when compared to diesel. From the present study, it is concluded that the biodiesels derived from palm and rice bran oils with their different fatty acid composition, show lower exhaust emissions and closer performance characteristics to diesel.

Opis:
Following the modern fuel market, one can notice that prices of liquid petroleum derivatives - petrol and diesel oil - which most often fuel piston internal combustion engines are increasingly higher. Similarly, the price of petroleum-derivative gas (LPG - the liquefied petroleum gas - simply speaking, a mixture of propane and butane) is also growing. Many academic and industrial institutions of science conduct research to determine whether it is possible to replace liquid petroleum-derivative fuels with some other potentially cheaper ones. It would also be beneficial if these new fuels were more "ecological" - so that their combustion products would not be harmful for the environment and if they were produced with the use of plants. Fuel stations commonly offer a fuel for diesel engines which is a mixture of fatty acids methyl esters (FAMEs) from vegetable oils, in Poland for instance from rape seeds. The paper presents a comparison of selected operating parameters of the Hatz 1B40 engine fuelled with mixtures of diesel oil or liquid bio-fuel and natural gas. Indicator diagrams, exhaust gases composition and vibration signals recorded on the engine body were analyzed. The study was conducted on the Hatz 1B40 diesel engine which is used among others in FOGO power generator sets, after replacing the original feeding system by common rail system for liquid fuels and after adding natural gas feeding system.

Opis:
The following paper introduces a retrofit proposal for marine fuel oil system arranged to burn heavy fuel oil and low-sulphur distillate grade. In the face of tighter requirements regarding sulphur content in fuel, which are obligatory both inside Emission Control Areas and among international waters, it is necessary to provide safe and efficient ship operation. Conventional methods for fuel change-over between heavy fuel oil and distillate grade are saddled with necessity of constant process control and compulsory engine load reduction during the realization of procedure. It ensures that maximum fuel temperature gradient amounts 2 °C/min, which protects injection system against thermal shock. The solution proposed by MAN Diesel & Turbo in cooperation with LEMAG Lehman & Michels turns mentioned procedure into unusual until now level thanks to guaranteed safety, control, smoothness and degree of automation. So-called Diesel Switch constitutes automatic fuel change-over system, which implements the process free from engine load factor. A built-in programmable logic controller and specially designed nonproportional valve enable to achieve smooth and linear characteristic of change. Furthermore, device controls other fuel oil system elements and also registers procedure run. The second element in retrofitted system concerns the way of distillate fuel cooling. Sulphur in the chemical bonds with other fuel components reveals lubricating properties. Reduction of its amount simultaneously with usage of low-viscosity distillate fuel creates a risk of damage to plunger and barrel assemblies. A guarantee of proper hydrodynamic lubrication film in injection system involves maintaining a minimal fuel viscosity of 2 cSt at engine inlet. Commonly used central cooling system on ships has a significant limitation. Water from low temperature cooling circuit, which provides a coolant cannot decrease fuel temperature below 40 °C. Applied solution proposed by Novenco is concerned with chilled water system assembly, which can cool down fuel even below 0 °C through vapour compression or an absorption cycle. As a result, low-sulphur fuel viscosity can be increased at any load independently of seawater temperature.

Opis:
In practical diesel engines it is to achieve a low emission and low fuel consumption under from low to high load operation conditions. Several techniques were developed for the low emission and high efficiency, such as Homogeneous Charge Compression-Ignition Engines and the blend fuels. Nevertheless, there are only few data available for reducing the emissions and fuel consumption of small diesel engines by using blend fuels. This experiment has been carried out to examine the influence of alcohol blend fuels on combustion characteristics for small diesel engine. The fuels used in this study are light oil (Standard), ethanol, propanol and butanol. The combustion behaviours, such as the emissions in exhaust gas (NOX, CO, CO2, O2 concentration), fuel consumption rate are observed. The main conclusions are as follows: 1) it is possible to control the combustion behaviour by using alcohol blend fuels for small diesel engine, 2) the fuel consumption of at any alcohol blend fuels is bigger than that of light oil, 3) the net thermal efficiency of some alcohol blend fuels (E5P5, P5B5, E5B5) slightly increases than that of light oil, 4) the NOx emissions for all the alcohol blend fuels are smaller than that of light oil, 5) the CO emissions are remarkably bigger than that of light oil under from low to middle engine load without the ethanol 10% addition.

Opis:
There has been increasing interest in recent years in the use of biodiesel as a substitute for petroleum-based diesel fuel. Fatty acids methyl esters (FAME) in a pure form are applied as a biodiesel B100 or as blends with diesel fuels named as the B10 biodiesel, the B20 biodiesel etc. FAME is susceptible to oxidation and to changes of other essential parameters during aging processes, which have an essential influence the NOx emission. Change of biodiesel parameters results in deterioration of fuel working properties and in increase of the NOx emission level. The increased NOx emission level is accompanied with high viscosity. Experiments with the PDPA laser-equipment showed that high content of biodiesel in a fuel increases the Sauter Mean Diameter (D32) of a fuel spray. The Sauter Mean Diameter increases with time of the aging process of biodiesel, what additionally can unfavourably influence the level of emission of exhaust gases. The research results of samples of aging processes of Rapeseed Methyl Ester (RME) accomplishing requirements of the EN 14214 European Biodiesel Standard, diesel fuel accomplishing requirements of the EN 590 (for based diesel fuel and blends of based diesel fuel and RME containing 1%, 5%, and 20% RME) are presented in the paper. Determination of influence of the fuel properties and the aging process on the acid number, kinematic viscosity, cloud point, cold filter plugging point, and pour point of fuel samples was an aim of performed research, as well the aging RME effect on elastomers comparatively with fresh RME. The process of fuel samples aging was enforced by the daylight (sun) effect, air, the elevated temperature and water. Fuel samples were aged in laboratory conditions during 15 and 60 weeks. Then the changes of fuels properties with relation to the same properties in initial conditions were determined. The water presence intensifles the process of the RME aging, especially in longer contact. An essential novel aspect of the paper is a relation determined between changes of biodiesel properties during aging and the NOx emission level that is connected mostly with increased viscosity. Rise of viscosity increases size of droplets of spray ed fuel, which results in increased emission level. Prevention of viscosity changes is an efficient way of the NOx emission decrease.

The influence of oxygenated diesel fuel containing n-butanol on a passenger car exhaust emissions was tested over the NEDC transient cycle. The tests showed that a diesel fuel/butanol blend, containing 10% of n-butanol, caused a significant decrease in PM and smoke emissions, had no effect on NOx and CO2 emissions and brought about higher CO and HC emissions. The most favourable fact resulting from the butanol application as diesel fuel component is that it produces desirable changes in PM/NOx trade-off.

The presented paper shows the results of the laboratory study on the relation between chosen malfunctions of a fuel injector and composition of exhaust gas from the marine engine. The object of research is a marine 3-cylinder, four-stroke, direct injection diesel engine with an intercooler system. The engine was loaded with a generator and supercharged. The generator was electrically connected to the water resistance. The engine operated with a load between 50 kW and 250 kW at a constant speed. The engine load and speed, parameters of the turbocharger, systems of cooling, fuelling, lubricating and air exchange, were measured. Fuel injection and combustion pressures in all cylinders of the engine were also recorded. Exhaust gas composition was recorded by using a electrochemical gas analyzer. Air pressure, temperature and humidity were also recorded. Emission characteristics of the engine were calculated according to ISO 8178 standard regulations. During the study the engine operated at the technical condition recognized as „working properly” and with simulated fuel injector malfunctions. Simulation of malfunctions consisted in the increasing and decreasing of fuel injector static opening pressure, decalibration of fuel injector holes and clogging 2 neighboring of 9 fuel injector holes on one of 3 engine cylinders.
