ダヘツド。 The number of intake valves and the number of exhaust valves in each cylinder are different, and a pair of camshafts that open and close these intake and exhaust valves are disposed between the cylinder head and a head cover that covers the top surface of the cylinder head.
In the OHC engine, the cylinder head is provided with a protruding wall that divides the space between the head and the head cover into an intake valve side chamber and an exhaust valve side chamber, and locally communicates these two chambers. A cylinder head for a DOHC engine, characterized in that a communication part is provided, and a blow-by gas outlet is provided in the head cover at a location on the side of the two chambers having fewer valves and away from the communication part. .
