Your question: Do 4 stroke engines have spark plugs?

Is there a difference between 2-stroke and 4-stroke spark plugs?

The differences between two-stroke and four-stroke engines

The first difference is the fact that the spark plugs fire once every revolution in a two-stroke engine, while firing is once every other revolution in a four-stroke engine. … A four-stroke engine has a separate compartment for the oil and doesn’t require mixing.

How often does a spark plug fire in a 4-stroke engine?

Two-stroke engines fire once every revolution, while four-stroke engines fire once every other revolution. This gives two-stroke engines a significant power boost.

What does the spark plug do in a 4-stroke engine?

A spark plug is used as a source of ignition, as the “spark” in its name implies. It is a key component of internal combustion engines and its primary function is to ignite a fuel/air mixture within the combustion chamber of a car, or other system. … 4-stroke internal combustion engine.

What are the advantages and disadvantages of a 4-stroke engine?

More fuel efficiency :- 4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes. Less pollution :- As power is generated once every 4 strokes & also as no oil or lubricant is added to the fuel; 4 stroke engine produces less pollution.

Which engine is not used in spark plug?

Why do diesel internal combustion engines require no spark plug to ignite the fuel unlike petrol engines? Spark plugs are used in the petrol engines to ignite the air fuel mixture whereas in diesel engines the presence of spark plugs is not necessary.
