i do agree with the safety concerns of LPG, abt the fule, if we arrest knocking also, what are the factors which will affect the engine life, such like, corrosion,...

if SI engine fuel is changed from Petrol to LPG (Liquified petroleum gas), will there be any drop in engine life. What are the adverse effects expected from the outcome...

one confusion, you mentioned for CI 25:1 Effcy is 44.12 and for CI 14:1 Effcy is 55.7, why for a high CI, effcy is less ?

thx nany, what is the max thermal effy for a Diesel engine (Idle conditions) what is the max thermal effy for a Petrol engine (Idle conditions)

What is the max thermal efficiency of a CI & SI engine, Why CI engine is having more thermal efficiency ?
