Pure vegetable oils have the greatest promise for alternative fuels for internal combustion engines beside the depletion of conventional petroleum resources. Among various possible options, pure vegetable oils present promising of greener air substitutes for fossil fuels. Pure vegetable oils, due to the agricultural origin, liquidity, ready availability, renewability, biodegradability are able to reduce the CO2 emissions in the atmosphere. Also, in Vietnam, pure vegetable oils such as soybean oil (SoO100), coconut oil (CO100) and sunflower oil (SuO100) are available. The paper presents the results of using heated pure vegetable oils for diesel engine D243 with power of 80 hp (58.88) kW. The results of determining the power (Ne), specific fuel consumption (SFC) and efficiency (n) are used to evaluate the performance of engine. The results show that, the engine power (Ne) is 10%-15% lower, the SFC of engine D243 using pure vegetable oils is 3%-5% higher and the η is 2.5%-6.2% lower compared to diesel oil (DO). Among the pure vegetable oils, the best performance results for D243 diesel engine are obtained from heated pure sunflower oil up to 135oC.

The problem of the military vehicles engines fuelling increases with the growth of the amount of vehicles in the armies. At the same time, another problem with fuel supply in modern engines is the use of bio component additives, which changes characteristics (quality) of the used fuels. Therefore, it is important to take actions to adapt engines to powering with fuels coming from renewable sources.The aim of the research was to evaluate the possibility of feeding the diesel engine (influence on the useful parameters and composi-tion) with mixtures of the unified battlefield fuel F-34/F-35 with biocomponents in the form of anhydrous ethyl alcohol and RME. The tests were conducted during fuelling of the engine with six kinds of fuels: basic fuel (diesel oil), NATO code F-34/F-35 fuel, as well as fuel mixtures: F-34 and RME with different ratio and F-34/F-35 with bioethanol. In the result of the research it was concluded that the parameters of the G9T Renault engine with the common rail fuel system in terms of F-34 and RME consumption (using) decreased in comparison to diesel oil basic fuel. It is not possible to supply the engine with the mixture of ethyl alcohol and F-34 fuel – alcohol pre-cipitation and obliteration of fuel system components

This paper represents the mustard oil is a kind of renewable energy and alternative fuel of the future. In order to cope with the current situation of load shedding, and reduce dependence on imported fuels, the Bangladesh government to encourage the use of renewable energy. Because the diesel engine with multiple functions, including small pumping irrigation system and backup generators, diesel fuel is much higher than that of any other gasoline fuel. In Bangladesh, mustard oil used as edible oil has been all over the country. Mustard is a widely grown plants, more than demand in Bangladesh and the mustard seed is produced annually. Therefore, to use the remaining mustard oil diesel fuel as a substitute. Fuel properties determine the standard procedure in fuel testing laboratory. An experimental device, and then a small diesel engine made in a laboratory using different conversion from the properties of biodiesel blend of mustard oil. The study found, biodiesel diesel fuel has a slightly different than the property. Also observed, and bio diesel, engine is able to without difficulty, but deviates from its optimal performance. Biodiesel was different (B20, B30, B50) of the blends have been used in engine or a fuel supply system, in order to avoid the complex deformation. Finally, it has been carried out to compare the performance of different operating conditions with different blends of Biodiesel Engine, in order to determine the optimal blends.

In these years, a problem of air pollution in a global scale becomes a matter of great concern. In such social situation, diesel engines are strongly required to reduce the NOx and particulate emission in the exhaust gas. In this paper, measurements of particulate emissions from a low speed two-stroke marine diesel engine were conducted with several kinds of diesel oil and a heavy fuel oil, to know the characteristics of particulate emissions at the present situation. The effects of engine load and sulfur content of the fuel on the particulate emission have been examined. The particulate emission from the test engine was measured by partial-flow dilution tunnel system, and particulate matter collected on the filter was divided into four components, SOF (soluble organic fraction), sulfate, bound water and dry soot, by Soxlet extraction and ion chromatograph. Results show that the particulate emission from the test engine operated with heavy fuel oil is three times as much as the value with diesel oil and that not only sulfate but SOF and dry soot concentration increase with the increase in fuel sulfur content. It is also found that the conversion rate from sulfur in fuel into sulfate in particulate matter is nearly independent of the sulfur content in the fuel and increases with the increase in the engine load.

A comparative series of experimental tests has been performed on a 4-stroke multi cylinder indirect injection diesel engine fueled with diesel oil, pure gas-turbine fuel and gas-turbine fuel with additives. The engine has been equipped aimed at monitoring both the overall performances and the variation with time of the pressure in the pre-combustion chamber. Some key parameters have been investigated at different engine speeds and loads (ignition delay, pressure rise in the pre-combustion chamber, power output, specific fuel consumption, exhaust gas temperature) and discussed results are presented.
