2019-28-2382
Since the 20th century increase in the number of cars in the major cities is been a point of concern because of the toxic gasses being emitted from the engine of an automobile. These gasses are polluting the atmosphere and degrading the air to breathe. The main gasses responsible for the degradation of air quality are carbon monoxide, hydrocarbon and oxides of nitrogen. There is a necessity to find ways to reduce the pollution emitted into the atmosphere from the automobile. The source of emission is either evaporation from fuel tank or carburetor which is easy to be dealt with or harmful gasses due to improper combustion which is a concern for the environment. The two ways to reduce these emissions are, modification in the engine to minimize the production of harmful gases and to treat the harmful gasses emitted from the engine before blowing it into the atmosphere from the exhaust. Catalysts help to break harmful gasses into smaller compounds that are environment-friendly.

2019-28-2377
Engine performance significantly depends on the effective exhaust of the combustion gases from the muffler. With stricter BSVI norms more efficient measures has to be adopted to reduce the levels of exhaust emissions from the exhaust to the atmosphere. Muffler along with reducing the engine noise, is intended to control the back pressure as well. Back pressure change has significant effect on muffler temperature distribution which affects the NOx emission from the exhaust. Many research communications have been made to reduce the exhaust emissions like HC, CO and CO2 from the exhaust by using different generation biofuels as alternate fuel, yet they have confronted challenges in controlling the NOx content from exhaust. This work presents the combined effect of Muffler geometry modifications and blended microalgal fuel on exhaust performance with an aim to reduce NOx emission from the exhaust of a four-stroke engine.

The diesel engine is widely used for its high thermal efficiency and better fuel conversion efficiency. However, increasing usage of petroleum fuel and environmental degradation motivates to use renewable biofuels as a replacement to conventional diesel. Biofuels produced from non-edible sources can be used as a partial substitute of diesel for the significant growth of fuel economy and reduction of environmental pollution. Methanol can be implemented as a blended fuel in the diesel without affecting engine design. In this study, the effect of diesel methanol blends and injection parameters such as fuel injection pressure (FIP)and start of injection (SOI) on a common rail direct injection (CRDI) diesel engine performance and emission were investigated. Four blends were prepared by mixing diesel with methanol (5%, 10%, 15% and 20% by mass) and adding a certain amount of oleic acid and iso-butanol to get a stable blend.

The need of Diesel as fuel has greatly pressurized the now scarcely available natural resources and is likely to become a luxury for the future generations. This paper aims at finding an alternate for diesel that can hopefully reduce the pressure on its existing demand. This paper presents a comparative study on use of different blends of Jatropha Oil (J) and Ethanol (E) as fuel in a diesel engine to observe its performance and emission characteristics. The findings are later compared with corresponding values of neat Diesel as fuel. Since Jatropha oil is more viscous and has polyunsaturated characteristics in its natural form, its ethyl ester was produced by transesterification process and later blended with Ethanol in different proportions like 90% J 10%E, 80J-20E, 70J-30E and 60J-40E.
