12:1 for rich mixture and it is 15:1 for lean mixture
Check spelling and state context
The pressure ratio in jet engines is the ratio of pressure between the entrance of the compressor and the exit of the compressor.
The air fuel ratio of the petrol engine is controlled by Carburetor
S.I Engine lower compression Ratio is 6 to 11

because a diesel engine ignites its fuel with pressure, and not with a spark like a petrol engine. that is why a petrol engine does not need as high a compression ratio as a diesel engine
The ratio is about 15:1 fuel to air.
what is the compression ratio,boreXstroke & dimension of 4g69 engine.
It depends on the engine.
The compression ratio of a Diesel ranges from 14:1 to as high as 25:1. I agree just depends on engine.
8th number/letter in VIN
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.
