Engine Valves

In Simple Terms

F1 engines must have exactly two intake valves and two exhaust valves in each cylinder. These valves must be traditional poppet-style valves (the most common type) that open and close using camshafts, and the sealing surfaces must be circular and located either on the cylinder head or approved inserts.

• Each cylinder requires exactly 2 intake and 2 exhaust valves
• Only reciprocating poppet valves mechanically actuated by camshafts are allowed
• Valve sealing interfaces must be circular in shape
• Sealing surfaces must be on the cylinder head or conventional approved inserts
