The 'strokes' refer to (1) intake (of fuel-air mixture into the cylinder head), the (2) compression of these gasses, the (3) ignition (or combustion) of the mixture to force the piston down in the cylinder and (4) exhaust of the burned gasses into the exhaust system.
These activities (or 'strokes') require the synchronization of the valves (opened and closed by the camshaft rotation) with the motion and position of the piston so that both intake and exhaust valves are closed when the piston rises to compress the gasses and open when the piston rises to expel the burned gasses. Intake valve(s) open to allow fuel-air into the cylinder and exhaust valve(s) open to allow the rising piston to force burned gasses into the exhaust system. Of course, the ignition system must send a spark to the plug at the correct time for this all to work.

What is a cycle in a 4 cycle engine?
The 4 strokes of an internal combustion engine are as follows:- 1 Induction stroke 2 Compression stroke 3 Power stroke 4 Exhaust stoke
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.
What about 4 stroke?
A 4 stroke engine is also referred to as a four cycle refers to the internal combustion whereby the piston completes 4 separate strokes with a single thermodynamic cycle.
Why are they calledFour-stroke engine?
Because it takes 4 strokes to complete i cycle. 1, intake stroke. 2, compression stroke. 3, power stroke. 4, exhaust stroke.
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 is the 4 stroke cycle in a petrol engine?
The 4 strokes of an internal combustion engine are as follows:- 1 Induction stroke 2 Compression stroke 3 Power stroke 4 Exhaust stoke
How many strokes are in a 2 cycle engine?
Cycle means the number of piston strokes for a complete cycle. 2 stroke= 2 cycle.
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 does 4-strokes engine work?
1st stroke, intake. 2nd stroke, compression. 3rd stroke, power. 4th stroke, exhaust. The 4 stroke cycle take 2 full revolutions of the crankshaft.
The burning air-fuel mixture forces the piston down on what stroke?
Depends on if this engine is a 2 stroke, 4 stroke, or rotary engine. I assume you are referring to a 4 stroke as found in the vast majority of automobiles built today. The answer is, At the top of the compression stroke. The 4 strokes of a 4 cycle engine are:# intake/induction stroke # compression stroke # power stroke # exhaust strokeDepends on if this engine is a 2 stroke, 4 stroke, or rotary engine. I assume you are referring to a 4 stroke as found in the vast majority of automobiles built today. The answer is, At the top of the compression stroke. The 4 strokes of a 4 cycle engine are:# intake/induction stroke # compression stroke # power stroke # exhaust stroke
How many revolutions of the crankshaft does it take to complete the cycle of a 4-stroke cycle engine?
It takes two revolutions of the crankshaft to complete the cycle of a 4-stroke cycle engine. Each revolution includes the intake, compression, power, and exhaust strokes of the engine.
Is a ktm 65 sx 2 stroke or 4 stroke?
Some of them are two strokes an some are 4 strokes Most of them are 2
