Q: In many Asian countries 2-stroke engine vehicles are contributing a lot in the smoke pollution. They sohuld be replaced with 4-stroke engine. How can we acheive this?
A: Yes ofcourse!! we have to convert all two stroke engines into four stroke. there are many concern for that. 1.Availability of the fuel is becoming a big problem for us now. so saving the fuel is one important creteria. 2.Pollution, due to the emission of the carbon monoxide the climate itself is getting changed in the entire part of the world and the problem like cancer, asthma etc. so if we are not controlling the pollution emission then it will be a big problem for the next generation. 3.Sound pollution, the two stroke engine will give more noise than the four stroke. we cannot compare the energy which is given by the two stroke engine with four stroke engine because eventhough it gives more energy some amount of the fuel is burnt unneswserly which is emitting pollution as well as fuel waistage. we can design the engine in such a way to get more energy out put with four stroke cycle.
