Abstract

Better fuel economy and higher power with lower maintenance cost has increased the popularity of diesel engine vehicles. Diesel engines are used for bulk movement of goods, powering equipment, and to generate electricity more economically than any other device in this size range. The diesel engine is typically more efficient than the gasoline engine due to higher compression ratio. Diesel engines also do not suffer from size and acceleration limitations, which the SI engine is prone to. But now a day’s problems are arise with the energy crisis and air pollution across the world due to the vehicles. Energy crisis increase the demand of fuel economy of vehicles. EGR, WI, WDE, OEC technique displaces oxygen into intake air and lower oxygen concentration in combustion chamber, which lower the flame temperature and increase the specific heat of inlet charge, which control the NOx and improve performance. EGR, WI, WDE, OEC techniques does not give effective result at higher load. It also higher soot deposit on the combustion chamber parts. From the some changes in catalytic convertor it should give some positive result to reduce NOx. There are many work have been done on SI engine using different changes on catalytic convertor. And it gives very positive result on NO¬¬x¬emission and performance.So from analysis of literature survey it concluded that there is good scope of experimental study on CI engine with changes in catalytic convertor.
