The Exhaust Valve Usually Starts Opening at Sarah Lewis blog

The Exhaust Valve Usually Starts Opening. Valve failures are often the result of detonation, poor quality or defective valves, a driver who’s zinged the engine, improper valve lash, or sloppy machining. On the intake stroke, the intake valve will be open and a mixture of air and fuel can enter. The exhaust valve has closed just after the piston started down and the intake valve is opening very quickly. Always refer to the oem timing procedure so you know. Exhaust valve opening (evo) overhead cam timing can be tricky on some engines. Valve seat concentricity is critical for proper alignment and a tight compression seal. The exhaust valve opens at bdc and stays open during the exhaust stroke, and potentially stays open until the start of the intake stroke. The valve will then close so that the mix can be compressed and burned, then the exhaust valve opens on the exhaust stroke so that the burned mixture can be forced out by the upwards movement of the piston. It closes after quite a few degrees of piston reaching the. The inlet valve usually opens few degrees before the piston reaches tdc in its exhaust stroke. The cycle starts with the intake stroke, near top dead center (tdc), where the piston is at its highest possible.
