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.
Suck, squeeze, bang, blow. :) Intake, compression, power, exhaust.
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.
Each piston has one TDC position, when it is at its maximum height. During the four stroke cycle, each cylinder has two TDC events. Those are compression and exhaust.
four stroke.
