between 18 and 25 to one depending on engine

I agree. It all depends on what engine you have.

How does compression ratio affect engine efficiency and performance?

Engine efficiency is increased though compression ratio by allowing a more thermodynamic energy to be converted into mechanical energy. Energy transfer is the key to efficiency.


What is the compression ratio for a 1997 Mach 1?

The 1997 Ford Mustang Mach 1, equipped with a 4.6-liter V8 engine, has a compression ratio of 9.85:1. This ratio contributes to the engine’s performance by balancing power output and fuel efficiency. The higher compression ratio allows for better thermal efficiency, enhancing the overall driving experience.


What is meant by cetane number?

A cetane number is a rating given to diesel fuels. It is a rating of how fast the diesel fuel ignites under compression. In diesel engines, there are no spark plugs and the engine uses compression (pressure) to cause ignition.


How much will milling gt40p heads 40 000 raise your compression?

Milling GT40P heads by .040 inches can increase the compression ratio by approximately 0.3 to 0.5, depending on the specific engine setup and current compression ratio. The exact increase also depends on factors like the piston design, cylinder volume, and head gasket thickness. It's important to calculate the new compression ratio using these variables to ensure optimal performance and prevent potential engine damage. Always consult with a professional or use a compression ratio calculator for precise measurements.


What is the total displacement in cubic inches of a v6 engine when the compression ratio is 3-3 and 1 half Does it equal 173 cubic inches?

The compression ratio doesn't deal with the displacement, the bore and stroke do. If it's a modern engine it should say the size of the engine in liters. You can use this to convert the engine size to cubic inches. A 173ci engine is a 2.8L engine when converted.

What is the compression ratio of a diesel engine?

The compression ratio of a Diesel ranges from 14:1 to as high as 25:1. I agree just depends on engine.


Why compression ratio of petrol enine is 8 where as diesel engine is 22?

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

How much compression should a diesel have?

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.


Why diesel engine car is costlier than petrol engine car?

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.

What happens when a diesel engine intakes natural gas through the intake proccess?

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
