吸排気装置。 The alcohol fuel spray is combusted by the intake air taken in through the intake system, and exhaust gas is discharged through the exhaust system, and the unburned components in the exhaust gas are transferred to an oxidation catalyst installed in the exhaust system. The apparatus is configured to include a temperature sensor for detecting the temperature of the oxidation catalyst and a throttle valve for throttling the intake system, and when the temperature of the oxidation catalyst is low, the intake air is reduced by the throttle valve. An intake and exhaust system for an alcohol engine characterized by a narrowing system.
