As a kid I was always told: Suck-Squeeze-Bang-Blow!
Induction, Compression, Expansion (or Ignition), Exhaust
- As the piston is drawn down, the inlet valve opens and fuel mixture is drawn in with fresh air. (with turbo engines, it's pushed in)
- Piston rises and the inlet valve closes compressing the gases
- Around tdc the mixture is ignited (spark - Petrol or by the heat caused during compression - Diesel) and the piston is forced down by the expanding (ignited) gases
- Piston rises and the exhaust valve opens to allow the burnt mixture to be forced out.

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.
Why is a 2 stroke faster?
A 2 stroke fires each cylinder, every revolution. In comparison a 4 stroke only fires half the cylinders every revolution. So a 250cc 2-stroke engine should have the same power as a 500cc 4stroke(has the same amount of CC's fired per revolution).
How many rotations of the crankshaft are required to complete each stroke of a two stroke cycle engine?
one rotation
The volume of blood pumped during each cardiac cycle is called what?
That is called the stroke volume.
Technician a says the otto cycle gasoline engine has four strokes per cycle technician b say that crankshaft makes four revolutions during four stroke cycle who is right?
Technician A is correct. The crankshaft must revolve two times to complete one cycle, which as 4 strokes. One half revolution for each stroke. Intake, compression, combustion, exhaust = four strokes to complete a cycle. One half revolution for each stroke of the piston going up or down. Look at a diagram and you'll see this is pretty simple.
How many top dead center in a four stroke engine?
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.
How many rotation of the crankshaft are required to complete each stroke of a four stroke cycle engine?
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.

How many revolution the crankshaft make in a four stroke cycle engine to complete on thermodynamic cycle?
The crankshaft makes two complete revolutions to complete one thermodynamic cycle. The crankshaft rotates 180 degrees during each stroke of the engine. Hence a total of two revolutions occur after completion of the four strokes. Chechout "www.howstuffworks.com " to see how crankshaft works.
What is faster two stroke or four stroke?
It is generally accepted that a 2-stroke is more powerfull than a 4-stroke - for each full cycle (induction, compresion, ignition, exhaust) a 2-stroke engines crank rotates twice and a 4-strokes engine rotates 4 times. Therefore, for each 4-stroke Bang you get Bang, Bang from a 2-stroke! 4-stroke engines are far more efficient though and 2-stroke engines are getting close to being legislated out of existence (we have just lost 250cc Motorcycle GP racing in preferance for 600cc 4-strokes).
What is stroke volumes and cardiac output?
Systole refers to the contraction of muscle fibers in the myocardium, diastole refers to relaxation of the fibers in the myocardium, stroke volume is the volume of blood ejected from the heart during the cardiac cycle. Finally the cardiac cycle refers to all of the aforementioned items and is the entire cycle of the heart from systole to diastole. Mike Branch HAMILTON ISLAND EMERGENCY RESPONSE TEAM.
Why do most very large engines operate on two stroke cycle?
very large is the keyword here. for a very large engines that runs large machines, we need high power engines. two-strike cycle engines produce more power than 4-stroke cycle engines. that's why they are used. as they produce more pollution than 4-strokes, they must be limited to small spaced engines machines or large machines that required very high power.
