if you see the difference between valves
valves are use in four stroke engine, and ports are use in two stroke engine.
4stroke engine are stronger than 2stroke cause you get to break down on a 2 stroke
For two Stroke Engine TVS50 is a Example and for Four Stroke Engine Pulsar, Apache are the examples......
The four strokes of an engine, in proper order, are: intake, compression, power, and exhaust. During the intake stroke, the engine draws in air and fuel. Next, the compression stroke compresses the mixture, followed by the power stroke where the mixture is ignited, creating power. Finally, the exhaust stroke expels the spent gases from the combustion process.
Nikolaus Otto invented the four-stroke internal combustion engine
Explain the advantages of four-stroke engine over two-stroke engine
in my opinion a two stroke engine is a better quality engine as compared to a four stroke engine!
two stroke
Four stroke engines are quieter than two strokes, but have less power.
compare the two stroke and four stroke engine in power output and thermal efficiency?
In a four-stroke engine its called the compression stroke
The four-stroke engine produces 1 power stroke for every 720 degrees of crankshaft rotation.
The four strokes of a four-stroke engine are the intake, compression, power, and exhaust strokes. During the intake stroke, the engine draws in air and fuel. The compression stroke then compresses this mixture, followed by the power stroke, where the spark plug ignites the mixture, generating power. Finally, in the exhaust stroke, the engine expels the burnt gases from the combustion process.
You can use four stroke oil for a (very) limited period in a two stroke engine in an emergency. However it is not formulated for two stroke engines and is not recommended.
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.
four stroke.
A two stroke engine combines the four strokes of a typical internal combustion engine into two strokes instead of four.
