Yes, until there is a rocker arm or camshaft installed to press valves open.
It is exactly what it says. The number of valves the engine has per cylinder. If you have 16 valves on an 8 cylinder engine, you have 2 valves per cylinder.
Camshaft opens and closes the valves The CAMSHAFT is connected to the CRANKSHAFT with gears so that the valves (intake and exhaust valves) are opened and closed at the proper time for each cylinder, and fully sychronized for with the movement of all of the other parts of the engine.
To determine if both the intake and exhaust valves are closed at Top Dead Center (TDC) for a cylinder, you can perform a visual inspection by removing the valve cover and observing the valve positions. Alternatively, use a compression gauge or a leak-down tester; if both valves are closed, the gauge will show pressure buildup without any significant drop. Additionally, checking the camshaft position relative to the crankshaft at TDC can confirm that both valves are in their closed positions.
Valves per cylinder makes one's engine more powerful or less powerful. A engine that has 2 valves per cylinder is better that a engine that has only one.
yes during ventricular systole AV valves are closed.
When #1 piston is at its upper most position in the cylinder bore and both intake and exhaust valves are closed
The piston is on the up stroke to compress so both valves are closed
Top Dead Center, unless otherwise specified, refers to when the piston in cylinder number one reaches the closest it can be to the cylinder head. All the valves should be closed at this point.
16 valves
When the engine is in time, cylinder 1 is at Top Dead Center (TDC) on the compression stroke. This means that both the intake and exhaust valves for cylinder 1 are closed, and the piston is at its highest point in the cylinder, ready for the ignition of the air-fuel mixture. Proper timing ensures that the engine's valves open and close in sync with the piston's movement for optimal performance.
3 valves per cylinder ( according to the owners manual )
