| 摘要 |
The present invention relates to a device for communicating the intake and exhaust ports of the multicylinder internal combustion engine used for vehicles, vessels, and so on, which transports an explosive exhaust pressure from the exhaust stroke in one cylinder to another cylinder on the suction stroke as a suction pressure correspondingly to improve an air suction speed and an air intake amount, and temporarily stores suction gas remaining in the suction pipe after the suction stroke and intakes the suction gas at a high speed into the cylinder on the next suction stroke to restrain suction interference as well as to improve suction efficiency, and temporarily stores a part of exhaust gas exhausted in a high pressure on the exhaust stroke and successively exhausts the exhaust gas after a predetermined time lapses to lower exhaust gas-induced noise. |
