Reed Valves.
An engine may have two, three, or four valves per cylinder.
An engine may have two, three, or four valves per cylinder.
There are two types of valves in an engine. The valves are located in the head. There are exhaust valves and fuel intake valves
It depends on which valves you are referring to. On a four stoke engine there are at least two per cylinder.
Valves control the in-flow and out-flow of fuel, air and exhaust fumes in a combustion engine (known as intake valves and exhaust valves). A 4-cylinder engine with 16 valves will have 4 valves per cylinder, with two intake and two exhaust valves per cylinder. With experience it is easy to tell the sounds of the valves apart because each engine sounds different with different valves. Generally the less number of valves means a deeper/throatier sound from the cars and vice-versa
Intake valve and exhaust valve.
An 8V engines, is a 4 cylinder engine with two valves per cylinder. A 16V engine has 4 valves per cylinder. More valves is like having bigger lungs, it will make more horsepower out of the same size engine.
Take the head off the engine then you will see the top of the valves. Look on the side of the motor right below the valves you will see a cover with two screws remove them and you will see behind it the stems of the valves - there are two springs you have to push one at a time and there is a slide clip which slides and pops off. Then push the valves up and pull it out of the engine.
Each cylinder has 5 valves. Three intake valves and two exhaust.
My 1991 Mazda 323 has two plastic screws on drivers side, facing engine. Are they airbleeder valves?
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.
