What is the compression ratio of and engine?

Compression ratio is the difference in the volume of a engine cylinder between when the cylinder is at it's largest volume, compared against when the cylinder is at it's smallest volume. Gasoline engines use 8:1 to 12:1 compression ratio. Diesel fuel engines use 14:1 to 25:1.

Why do diesel engines ignite even though they have no spark plugs to ignite this mixture?

Compression and heat. The fuel/air mixture is compressed to such a high level as to get hot enough to cause the mixture to self ignite. Gas engines require a spark to ignite the fuel. Gasoline engines have a compression ratio of 8:1 to 12:1. Diesel engines have a compression ratio of 14:1 to 25:1.

What is the compression ratio for gasoline?

It would vary between gas engines and how they were built, but most would fall between 8 1/2 to 1 and 11 to 1 compression ratio.

What is meant by the compression ratio of a combustion engine?

The compression ratio of a combustion engine is the relationship of the largest and smallest capacities of the combustion chamber. A higher compression ratio is advantageous because the engine operates more efficiently, extracting more mechanical energy from the fuel. Most gasoline-powered engines have a compression ratio of around 10:1.

What is compression ratio for petrol engine?

Different engines - different ratios, but commonly around 8 to1.

Do NASCAR engines use antifreeze?

Yes, NASCAR racing engines use antifreeze. There is no other way for them to keep the engine from overheating. NASCAR engines are similar to street engines but with more horsepower.

Does disel engines have a higher cc compared to petrol engines?

No..the compression ratio is much higher eg a small petrol engine will have a ratio of 8:1 where a diesel small engine has around 17:1..

Does NASCAR use turbocharged engines?

No, NASCAR engines are naturally aspirated and turbochargers are prohibited (not allowed).

Why high compression ratios are not used in spark ignition engines?

spark ignition itself can easily burnt the air fuel mixture hence the high compression ratio is not needed.
