Two. Intake, and exhaust.
Very simple The Reversible Process: That type of process that work cycle, it mean to complete revolution and come back to the initial point from where it start. Example are Carnot Cycle. Two and Four stroke engine. Irreversible Process: Opposite to reversible process called irreversible process. Example are Electricity
Mean effective pressure (mep ) is a parameter indicating a engine's performance, which is obtained by dividing mechanical work done in a cycle (W)by volume swept in a cycle (V). Clearly work is the product of pressure and volume or torque and angle. Since torque is a measurable quantity, the work per cycle can be calculated as W = T * 2pi ( 2 stroke engine), W = T * 4pi ( 4 stroke engine) therefore mep = W / V = T * 2pi / V or T * 4pi / V
cam less engine technology is the use of solenoids to open and close the intake and exhaust valves in a gasoline engine. Instead of using a camshaft, which has fixed timing limitations, solenoid controlled valves have unlimited timing ability therefor giving the modern engine maximum fuel efficiency and optimizing power and torque outputs on the fly via Computer controlled.
In a four-stroke engine, the intake valve opens in the intake stroke, allowing air-fuel mixture to enter, while the exhaust valve remains closed. During the compression stroke, both valves stay closed to build pressure. In the power stroke, the fuel ignites, pushing the piston down, with both valves still closed to retain pressure. Finally, in the exhaust stroke, the exhaust valve opens, allowing gases to escape, while the intake valve stays shut. This cycle repeats continuously, ensuring efficient engine operation.
A two-stroke engine does not have a cam or camshaft. Seeing there is no intake/exhaust valves it would be pointless to have a camshaft.
it varies a lot
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.
There is no camshaft in a 2-cycle engine.
A two stroke engine has half the strokes of an otto (or four stroke) engine, therefore it takes two crankshaft roatations to complete a cycle on a four stroke engine and only one revolution in a two stroke engine. There are several types of two stroke engines, the different types have to do with how the receive the air/fuel mixture, also you have two stroke diesel engines.
'a 4 stroke engine cycle' is usually what it is called...
The camshaft operates the valves on a 4 cycle engine.
the four stroke engine cycle
A stroke is half of a revolution.2 revs is 4 strokesone another is the samea 4 stroke engine goes through 2 revolutions to complete one cyclea cycle is an X number of strokes to complete combustion and power process in an internal combustion engine'The intake stroke is the first downward movement of the piston, half of a revolution. The next half of a rev is the compression stroke, then power stroke, and exhaust 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.
It is called the compression stroke.
