A two-stroke engine is an internal combustion engine that completes the process cycle in one revolution of the crankshaft (an up stroke and a down stroke of the piston, compared to twice that number for a four-stroke engine). This is accomplished by using the beginning of the compression stroke and the end of the combustion stroke to perform simultaneously the intake and exhaust (or scavenging) functions. In this way, two-stroke engines often provide strikingly high specific power, at least in a narrow range of rotational speeds. The functions of some or all of the valves required by a four-stroke engine are usually served in a two-stroke engine by ports that are opened and closed by the motion of the pistons, greatly reducing the number of moving parts.

What are the strokes in a two stroke diesel engine?
suction stroke and exhaust strokes are the two strokes involved in 2 stroke engine....
How does a two stroke engine combine the four strokes of a typical internal combustion engine?
A two stroke engine combines the four strokes of a typical internal combustion engine into two strokes instead of four.
What are strokes of a two stroke engine?
intake and exhaust
Why you prefer four stroke engine over two stroke engine?
Four stroke engines are quieter than two strokes, but have less power.
What is the difference in combustion in a 2 stroke engine and a 4 stroke engine?
2 stroke means it takes two strokes for a power stroke and 4 sroke takes four strokes for power stroke so in otherwise 2 strokes are way faster and more torqey
What is the difference between cycle and stroke?
In a two-stroke engine, two strokes is one cycle. In a four stroke engine, four strokes is one complete cycle. A stroke is a part of a cycle. Remember that the "up" motion and the "down" motion each count as one stroke.
What are the major difference between 4stroke engine and 2stroke engine?
A four stroke engine has 4 strokes per cycle, whereas the two stroke engine has only 2 strokes per cycle. Since the 2 stroke engine has twice as many power strokes as a 4 stroke engine at a given rpm, the 2 stroke is capable of making nearly twice the power of a 4 stroke for a given displacement.
If speed of a two-stroke engine is N then what is the speed of a four-stroke engine?
It could be anything. The difference between the two is that in a two-stroke engine the piston goes back and forth (two strokes) for every ignition event (spark plug firing for a gas engine or fuel injection for a Diesel), while it goes back and forth twice (four strokes) for a four stroke engine.
What is the difference between 2 stroke and 4 stroke?
in a two stoke engine ther is only two steps before it starts the cycle over, in a 4 stroke engine there is 4 strokes
How many strokes make 1 crankshaft rotation?
It depends on the type of engine. In a four-stroke engine, there are four strokes - intake, compression, power (combustion), and exhaust - required to complete one full rotation of the crankshaft. In a two-stroke engine, there are two strokes - compression/ignition and exhaust - needed to complete one rotation.
Which is better a two stroke or four stroke engine for a dirt bike?
i would say i two stroke because two strokes are much easier to fix, there faster and better.
Which is faster a two stroke dirt bike or a four stroke dirt bike?
Two strokes can accelerate faster but it depends on engine size
