The compression ratio of a Diesel ranges from 14:1 to as high as 25:1. I agree just depends on engine.
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
It has a compression ratio of 17.5:1
The Diesel
Because of higher compression ratio.
between 18 and 25 to one depending on engine I agree. It all depends on what engine you have.
Around 18:1 will give a running diesel on a engine such as an old perkins 4203
A diesel engine requires at least a 20:1 compression ratio, or about double a gasoline engine. The PSI this translates to depends on the size of the cylinder. You will need to consult the manufacturer's service manual.
Due to the increase in the compression ratio of a diesel which fires on compression rather than spark, the engine is built much stronger than a petrol engine. It therefore just costs more to manufacture.
The diesel engine is on compression.
Petrol or gasoline in a diesel will cause internal engine damage. if petrol is used in diesel engine it may cause explosive sound with burning ....bcz high compression ratio ......
a diesel engine has generally compression ratio of 12-14 which means around 1000cent.temp is developed inside the engine cylinder.if natural gas is intaken then it will burn before the completion of compression stroke.no diesel fuel is required now
