A petrol engine is called a spark ignition engine because it uses a spark plug to ignite the air-fuel mixture in the combustion chamber. When the engine's piston compresses the mixture, the spark plug generates a spark that ignites it, causing an explosion that drives the piston down. This ignition method distinguishes it from diesel engines, which rely on compression ignition. The term reflects the fundamental mechanism by which combustion occurs in petrol engines.
What else can I help you with?
Why petrol engine is called spark ignition engine?
Because the fuel is ignited by a spark plug rather than by compression as is the case with a diesel.
How many types of spark ignition engine?
There are basically two types of spark ignition engine. They are the diesel spark engines and the petrol spark engines.
What is spark ignition or Diesel?
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
Full form of SI engine?
SI stands for Spark Ignition. eg. Petrol Engine.
How are internal combustion engines?
you cut off the ignition spark in a petrol engine
How are internal combustion engines stopped?
you cut off the ignition spark in a petrol engine
What engine uses a spark plug to ignite a compressed air-gas mixture?
A spark ignition engine, like your average gasoline/petrol burning car engine.
What is spark ignition engine?
A 'spark ignition ' engine is your regular gasoline engine as opposed to a diesel, which is a 'compression ignition' engine
IS the petrol NECESSARY FOR burning combustion?
Yes, petrol is necessary for burning combustion in spark ignition engines. It serves as the fuel source that, when combined with air and ignited by a spark plug, initiates the combustion process that powers the engine.
What is the difference between a diesel engine and a petrol engine ignition of mixture?
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
Does an mpfi engine replace spark plug?
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.
What are the defferences between dessel and petrol engine?
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.
