ジン。 Three reciprocating movements of the piston in the cylinder constitute one cycle, and each stroke of suction, compression, explosion, exhaust, scavenging air intake, and scavenging air exhaust is repeated in this order, while the first exhaust port is filled with oxygen in the exhaust gas. An air-fuel ratio sensor for detecting the concentration is disposed, and a first exhaust passage for discharging burnt gas is connected thereto. A first exhaust valve that opens during the exhaust stroke is disposed, and a second exhaust passage is connected to the air-fuel ratio sensor for detecting the concentration. A second exhaust passage is connected to the port and is independent from the air-fuel ratio sensor and exhausts residual gas and scavenging air for removing the residual gas, and a second exhaust valve that opens during the scavenging exhaust stroke is disposed. , a first intake passage provided with a fuel supply device that feedback-controls the amount of fuel according to the oxygen concentration detected by the air-fuel ratio sensor is connected to the first intake port; A first intake valve that opens is disposed, and a second intake passage that is independent of the fuel supply device and supplies scavenging air for exhausting residual gas in the combustion chamber is connected to the second intake port. At the same time, a second valve opens during the scavenging suction stroke.
A scavenging engine characterized by being provided with an intake valve.
