The increasingly strict restrictions being place on diesel engine emissions have the interest in alternative combustion concept. The dual fuel engine exhibits much better emission characteristics than a diesel engine whilst having similar efficiency. The dual fuel engine is investigated for their potential to achieve near zero nitrogen oxide (NOx) and soot-particle emissions. In both SI and diesel...
Diesel engines are increasingly becoming important because of their fuel economy and efficiency. Now-a-days, ceramic coating over the cylinder head, valves and the piston top surfaces are provided for thermal insulation. These thermal barrier coatings reduce the heat transfer from the combustion chamber to the cooling jackets and to the atmosphere. This paper presents the investigation of the temperature...
Biodiesel is renewable and environmental friendly alternative diesel fuel for diesel engine. It can be produced from food grade vegetable oils, inedible oil, animal fats and waste or used vegetable oils, by transesterification process. Transesterification is a chemical reaction in which vegetable oils and animal fats are reacted with alcohol in the presence of a catalyst. The products of reaction...
In a normal diesel engine, about thirty percent of the total energy is rejected to the coolant. The low heat rejection concept is based on suppressing this heat rejection to the coolant and recovering the energy in the form of useful work. The purpose of this project is to increase the performance of the engine and improved the fuel economy resulting from coating those using partially stabilized zirconia...
Emission control is one of the biggest challenge in today's automotive industry. Emission control can be achieved either by controlling combustion or by treating the exhaust gas. The latter is comparatively easier since there is less or no need to modify the engine itself. One such after treatment method is the use of catalytic converter. But, the 3-way converter is expensive due to use of both platinum...
Ethanol is a bio-based renewable and oxygenated fuel, thereby providing potential to reduce the PM emission in diesel engine and to provide reduction in life cycle of carbon dioxide. So that reduces ozone layer depletion. There are several studies which reports improvement in the engine performance and emission by using ethanol blend fuels. Many researches going on in the area of ethanol as alternate...
