What happen when petrol fuel is use in diesel engine?

Petrol in a diesel engine will destroy the engine.


Is petrol is used in diesel cars?

No, diesel engine require diesel fuel. Put petrol in a diesel engine and you will destroy it.


Can a petrol engine be converted to a diesel engine?

No, you cannot convert a petrol to burn diesel.


Why not use petrol in diesel engine?

If you use Petrol or Gasoline in a Diesel engine you will destroy that engine. That is why you do not use it.


Can you make a diesel engine which works on the basic principle of petrol engine or you can say it uses diesel as a fuel but works on the principle of petrol engine?

No, a diesel is a compression firing engine and a petrol is a spark firing engine. Diesel fuel will not burn in a petrol engine with spark plugs.


Is it possible to use diesel in petrol engine?

No. A petrol or gasoline engine will not run on diesel fuel.


What is thermal efficiency of petrol engine?

The maximum Thermal Efficiency of Petrol Engine or Gasoline Engine or Otto Cycle Engine is about 25-30%.


Why diesel engine has more efficiency than petrol engine?

Diesel is a more combustible fuel than petrol, therefore less fuel is required to generate the same power as petrol. This also means that spark plugs aren't required, like in a petrol engine, since the diesel will ignite off engine compression alone. This also makes the engine arguably more reliable since there are less parts, and less things to go wrong.


Why cant petrol be used in diesel engine?

Because one has a petrol engine and the other has a diesel engine. Petrol/gasoline does not ignite the same way as diesel. It also does not have the lubrication qualities that diesel has. Gas in a diesel engine will damage the fuel system if the diesel very quickly.


Why diesel engine has volumetric efficiency greater than gasoline engine?

In diesel engine the air is only compressed in compression stroke and then diesel is entered .......so only small amount of fuel is consumed then petrol engine which take lot amount of fuel.......


Who is better gasoline engine or diesel engine?

diesel. Diesel engines tend to have better efficiency especially at less than full load. Gasoline/Petrol and LPG engines tend to have better power weight ratios.


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
