Petrol Engine
Today I am going to tell you guys about petrol engine it is a internal combustion engine and the combustion take place by igniting petrol by spark plug. One interesting this I would like to add here that petrol is a hydrocarbon and have eight carbons and 18 hydrogen. It has low density and low volatile hydrocarbon. Petrol engine of a car is light weight as compared to diesel engine due to low compression ratio of petrol as due to low volatility petrol get burn by giving ignition by shark plug. In ideal condition a 14.5:1 air to fuel ratio required for getting an optimal output from a petrol engine. Petrol engine has more rpm for a same distance than a diesel engine so that is why it wear tear fast and lead a low life in comparison of diesel engine of same capacity. In a cylinder piston move from top to bottom to take a suction of air and petrol mixture. Then this mixture start getting compressed as crank piston mechanism is design in this way to compress the mixture. When piston m...
