Best Answer

Diesel fuel is used in diesel engines as a partial lubricant. It also has a high flash point due the fact that diesel engines ignite the fuel by compression rather than spark. A gasoline engine on the other hand fires the fuel by spark and the fuel has a lower flash point. Gasoline has no lubricating qualities whatsoever. Diesel engines are designed to run on diesel fuel and the use of gasoline in a diesel engine will destroy it. Gasoline engines on the other hand will not even run on diesel but no damage will be done to the engine. You will however have to drain the fuel tank and flush out the fuel lines.

How can you change your diesel engine for petrol?

That is impossible. You cannot convert a diesel to run on petrol or vice versa.


Can diesel oil be used in a petrol engine or vice versa?

Because , petrol is ignited before or on reaching the dead center at low temparature. But diesel burns at high temp also that's why petrol is not sufficient to diesel engines.


What happens if petrol is used in diesel engine and vice versa?

If gasoline is used in a diesel it will damage the engine. If diesel is used in a gasoline engine it will do no real damage as the engine will not run.


Can you mix diesel oil with non diesel oil?

I am not sure what you are asking but putting oil for diesel engines in a gasoline engine with some oil in it would not be good, or vise versa


What happens if you put diesel in a petrol engine and vice versa?

Neither would run correctly if at all. Both could suffer major damage.


How do petrol and diesel engines work?

No. Diesel and petrol, while both petrochemicals, act quite differently. Petrol is ignited by a spark, and at a relatively low pressure. Diesel 'self ignites' when placed under sufficient pressure, therefore diesel engines do not use spark plugs, and require higher operating pressures to work. To allow for the different pressures, there are large differences between the designs of petrol and diesel engines, carburettors/fuel injectors and valve systems. The only way to convert a petrol car to a diesel (or vice versa) is a complete engine swap.


Why would a 1998 ford escort run rough or not start after fueling?

the only reason a car will run rough or not start after refueling is either the wrong type of fuel has been put in[i.e diesel into a petrol or visa versa]or the fuel put in is contaminated.


What would happen if diesel is let into a petrol engine or vice-versa?

I assume by gasoline that's the same as unleaded/petrol.... Well basically you will not do any serious damage to the engine itself, the car will stop working, quite possibly have some black smoke coming out the exhaust as the diesel works it way through, you will not be able to use the car until the entire fuel system has been drained out, so its a costly and frustrating mistake to make.


Why are multi cylinder engines preferred to single cylinder engines?

this is rhetorical when you think about it. when you have more cylinders, you have more power, but less fuel efficiency, and vice versa. In this answer its not all completely correct in some cases a multi-cylinder engine can have a better fuel economy compared to a single cylinder engine, it depends on the capacity of the of the cylinder, the size of the valves and how much they allow the fuel and air mixture (in S.I engines A.K.A petrol engines) or air for diesel engines. One reason that i know of for a multi-cylinder engine to be preferred to a single cylinder engine is because it gives less stress to the engine when running it also causes the engine to be more stable. In addition a multi-cylinder engine has less time between power strokes so the engine is more efficient.


How are heat engines classified?

heat engines are classified on the location of the combustion chamber , if it is outside the whole set up then it is external heat engine and vice versa.
