Because the fuel is ignited by a spark plug rather than by compression as is the case with a diesel.
There are basically two types of spark ignition engine. They are the diesel spark engines and the petrol spark engines.
spark ignition engine is also known as petrol engine. but in diesel engines the fuel is burnt due to the high compression of air.so there is no need of spark plug
SI stands for Spark Ignition. eg. Petrol Engine.
you cut off the ignition spark in a petrol engine
you cut off the ignition spark in a petrol engine
A spark ignition engine, like your average gasoline/petrol burning car engine.
A 'spark ignition ' engine is your regular gasoline engine as opposed to a diesel, which is a 'compression ignition' engine
petrol engine - Fuel and air mixtures together and compressed in engine. These mixtures ignited by Spark plug Diesel Engine - Air only compressed at high pressure and Temperature. Fuel injected at high temp so that the ignition takes place
No. Spark plugs remain in Petrol engines. MPFI stands for Multi Point Fuel Injection, thus replacing the carburetor with injectors. Petrol engines need a source for ignition unlike Diesel engines, where the ignition happens due to compression.
Petrol & Gas engines are spark ignited engines where as diesel engines are compression ignited engines. Petrol engines works with explosion of fuel air mixture due to spark from spark plug inside the cylinder. Diesel engines works with combustion of fuel air mixture due to compression, compressed mixture attains a very high temperature which exceeds the flash point of diesel and starts burning inside the cylinder and the hot gases after burning of fuel misture exerts force on piston which makes the diesel engines work. Diesel engines are highly efficient than petrol engines.
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.
