Why Is The Inlet Valve Clearance Always Smaller Than The Exhaust Valve Clearance? Why is the inlet valve clearance always smaller than the exhaust valve clearance? … The exhaust valve has a near constant flow of very hot air. Therefor the exhaust valve will expand more then the inlet valve and need more clearance because
What Happens When Both Valves Are Closed? During the compression stroke the intake and exhaust valves are closed. During the exhaust stroke, the exhaust valve is open and the intake valve is closed. … At no time are both valves open at the same time. On which strokes are both valves closed? 2. Compression stroke:
How Do I Know Which Valve Is Intake And Exhaust? If you are thinking how you can distinguish the intake from the exhaust valve, then they can most easily be differentiated by the diameter of the valve head. The intake valves have a larger diameter of the valve head, so they are larger. How do
At What Temperature Does The Exhaust Valve Open? When the valve opens and exhaust gas begins to flow out from under it, the valve is heated not only on the top of its head by combustion itself but the back side of it is heated as well by exhaust gas, whose temperature can be as
