valve timing diagram of two stroke engine

The gears keep the cam timing in sequence with the crankshaft. So the valves open when their suppose to and no damage occurs from valve to piston clearances.

could you display a diagram of a timing chain for vw polo 1.2 12 valve
variable valve timing is where the engine changes valve timing based on the driving situation much like ignition timing is changed to meet the needs of the engine in specific situations. in most cars valve timing is static and determined by the timing gear on the camshaft
Intake valve and exhaust valve.
for mechanical and dynamic requirements. By studing correct timing of opening and closing of inlet and exhaust valves improves power and efficiency of engine and reducing of fuel consumption be done.
In a two-stroke reed valve engine the reed valve is used to seal the fuel air mixture in the crankcase.
To set the V8 valve timing, first, ensure the engine is at top dead center (TDC) on the compression stroke for the number one cylinder. Align the timing marks on the crankshaft and camshaft gears according to the manufacturer's specifications. After securing the timing chain or belt, check the valve clearance and adjust if necessary. Finally, double-check all alignments and reassemble the components before starting the engine.
If the valve timing is correct and there are no damaged engine parts (or weak/faulty valve springs) that should not happen, yet however if the engine is "over-revved" the valves could "float" which is not normal operation. (If the engine is an interference engine there may possibly be engine damage.) That is normal and it is called valve overlap.
valves are use in four stroke engine, and ports are use in two stroke engine.
It relieves the cylinder of exhaust on the 4th stroke of a 4 stroke engine.
