It differs from a diesel engine in the method of mixing the fuel and air, and in the fact that it uses spark plugs to initiate the combustion process. In a diesel engine, only air is compressed (and therefore heated), and the fuel is injected into the now very hot air at the end of the compression stroke, and self-ignites. In a petrol engine, the fuel and air are usually pre-mixed before compression (although some modern petrol engines now utilise cylinder-direct petrol injection). The pre-mixing was formerly done in a carburetor, but now (except in the smallest engines) it is done by electronically-controlled fuel injection. Pre-mixing of fuel and air allows a petrol engine to run at a much higher speed than a diesel, but severely limits their compression, and thus efficiency
What else can I help you with?
Is fuel for a two stroke engine fatal to a four stroke engine?
No it isn't fatal, but it would smoke quite a bit, because a two stroke engine needs two stroke oil mixed in the petrol, and a four stroke just needs petrol.
Can you reverse the spin of a small engine?
Petrol engine? 4-stroke, no. 2-stroke, some.
Advantages and disadvantages of four stroke petrol engine?
One advantage of having a four stroke petrol engine is the fuel economy. A disadvantage of the engine is in the cold weather they are harder to start.
What will happen if you put petrol in a 2 stroke engine?
It will overheat the engine
How Air cooling of 4 stroke single cylinder motorbike petrol engine occurs?
The air cooling of a 4 stroke petrol engine takes when the air flows on the engine .it takes not by radiation.
What happens if you put 2 stroke petrol into a 4 stroke engine?
nothing the 2stroke-petrol will smoke as it burns the oil which should be mixed in it
Is 4 stroke fuel normal petrol?
4 stroke fuel is straight petrol, it does not have oil in it! If you use it in a 2 stroke engine you will seize the motor. 2 stroke fuel has oil added to it.
Does a 4 stroke engine use unleaded petrol?
Yes
Disadvantages of six stroke petrol engine?
high cost
Advantages of two stroke engine over a four stroke engine?
Explain the advantages of four-stroke engine over two-stroke engine
Principal of four stroke petrol engine?
4stroke engine are stronger than 2stroke cause you get to break down on a 2 stroke
What happens if petrol mix with engine oil in a 4 stroke engine?
If petrol mixes with engine oil in a 4 stroke engine then the mixture becomes thick and its combustion will not be efficient. The exhaust will be smoky due to this incomplete combustion. also this will reduce engine efficiency.
