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......
Nikolaus Otto invented the four-stroke internal combustion engine
The camshaft operated the inlet and outlet valves in the cylinder to admit fuel to the engine before ignition and expel the exhaust gas after the power stroke. The camshaft operates at half the crankshaft speed in a four-stroke 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.
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.
A 1993 Honda xr100r would have a four stroke engine.
