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
What is the compression ratio on a 1.4 corsa petrol engine?
For the Opal Corsa generation Corsa B, 1.4 i petrol engine, the compression ratio is 9.4. It has 60 horsepower and a 46 liter fuel tank. For the 1.4 XER, the compression ratio is 10.5. For the 1.4 i 16V ECOTEC, the compression is 10.5.
Why is diesel engine more expensive than petrol engine?
Because of higher compression ratio.
What is the compression ratio of a petrol engine?
It can be anywhere from 8.5 to 1 for a normal car to 13 to 1 or higher for a race engine.
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..
What is the maximum pressure and temperature produced inside a four stroke petrol engine for a given compression ratio?
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 will happen if petrol is used as a fuel in diesel engine?
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 ......
Is there any vehicle which can run on both petrol and diesel?
A vehical that runs on petrol and diesel is impossible as they are both ignited in different ways. For exaple petrol is ignited by the spark plugs and a diesel is ignited by the shear force of the compression from the pistons. A petrol engine has a round 9:1 compression ratio and a diesel has about 20:1 but these veary from engine to engine I hope that hasn't lost you
What is the typical compression in a diesel engine verses a petrol engine?
2.5 liter Petrol 8-1 diesel 25-1 compression
The air fuel ratio of the petrol engine is controlled by?
The air fuel ratio of the petrol engine is controlled by Carburetor
Why diesel engine generates more power than a petrol engine?
Higher compression ratio, therefore it develops far more torque which equates to pulling power.
