Which is more efficient a petrol engine or a diesel engine?
It will depend upon the conditions. Under normal operating conditions a diesel engine is more efficient than a petrol engine.
What is more efficient diesel or petrol car?
diesel is more efficient
Why diesel gives more milage than petrol and petrol car costly than diesel?
Diesel engines are more efficient and do use less fuel, but they do not cost less than a petrol engine, they cost more. Diesel fuel also costs more. A diesel engine will however last longer.
Is diesel or petrol more efficient?
Diesel engines are more efficient. They get better mileage, produce more torque, and last much longer than a gasoline engine. They are also more expensive to build.
What is more efficient the gasoline engine or diesel engine?
The diesel is more efficient but more expensive to build.
Which engine is more efficient diesel engine or gasoline engine?
Diesel engines are more efficient than gasoline engines.
What is better a diesel or petrol engine?
It's more a question of "different", than "better". Petrol engines can have better power-to-weight ratios, while diesels are a little more efficient.
Why a turbocharger is not used in a petrol engine?
They certainly are. Using them together with carburetted engines can be a bit tricky, and usually the compression has to be lowered when compared to a naturally aspirated engine.
Which is more efficient otto engine or diesel engine?
diesel cycle
Why petrol engines are faster than diesel engines?
Petrol engines are widely considered to be the most efficient of engines, because they are more refined than diesel. Since diesel is not completely refined, it cannot completely combust and so does not (in theory) produce as much energy per litre of fuel as a petrol engine. However, some diesel engines can be made to be much more efficient than petrol engines because they have a different type of fuel, and burn it in a different way.

Why is petrol engine RPM is greater than diesel engine?
for same power diesel engine produces more torque @ less rpm whereas petrol engine produces less torque @more rpm this difference is due to different combustion processes of diesel and petrol
Is the petrol engine is costly thab diesel engine?
No, diesel engines cost more to build than petrol engines. They are built much heavier.
