Claims

[Claims for Utility Model Registration] A combustion chamber that has at least two intake valves and has a convex ridge line formed between it and the exhaust valve, and an intake port that is branched on the downstream side and connected to the intake valves. an intake pipe having an intake pipe, a control valve capable of opening and closing the intake pipe is rotatably provided in the intake pipe, and the control valve has at least two notches at a position facing the intake valve. An internal combustion engine characterized in that intake air is introduced into the combustion chamber through the notch when the intake pipe is blocked.
