Respuesta :
The multivalve is a valve where the cylinder has two valves and the engine can able to operate at higher revolutions per minute than a two valve engine delivering power.
Explanation:
The valves are the mechanical control element used to produce fresh charge and allow burnt gases to move out of cylinder.
The fresh charge enters the inlet valve through inlet and burnt gases passes through exhaust valve and escapes through exhaust valve.
The intake valve is used to control the flow of fuel into chamber and exhaust valve controls the flow of exhaust gases out of the cylinder.
The valves that are having cold engine, oil consumption, off-throttle braking and excessive smoke are symptoms of bad valves. Intake valves are larger due to the air and fuel taken in by the engine is greater than exhaust valve.
