What is fuel air ratio?

Air to fuel ratio is the ratio between the weight of air to the weight of fuel, for example: 14.7 pounds of air to 1 pound of fuel would be a air:fuel ratio of 14.7:1 This particular example is called the stoichiometric ratio for gasoline...it's ideal ratio in order to efficiently use all the fuel. This ratio varies for different fuels....for example, ethanol fuels have a stoichiometric air:fuel ratio of 13.85:1. In actuality, a gasoline car gets it's best fuel mileage when the fuel is reduced slightly and produces it's best power when the ratio is a little heavier on the fuel side.

Can a petrol engine run on lean air-fuel ratio such as 30 by 1 while a diesel engine can?

No, the perfect fuel/air ratio is 14.6 to 1. A ratio of 13 to 1 is a safe ratio for most non turbo gas engines. Turbo engines can run a 12 to 1 ratio. Chrysler's lean burn system of the 70's and 80's used a ratio of around 18 to 1 and it was horrible. No gasoline engine can run at 30 to 1.


Why is dynamic compression ratio so important to engine durability?

Dynamic compression ratio is important to engine durability by ensuring its compatibility with a specific cam and octane. A higher ratio means the engine derives optimal mechanical energy from an air-fuel mixture.
