転式内燃機関の排気ガス浄化装置。 The cylinders of the internal combustion engine are divided into a first cylinder group and a second cylinder group, and each cylinder group is provided with an independent exhaust passage.
2 sensors and a catalytic converter are arranged, and the second sensor and catalytic converter are arranged.
A second O 2 sensor and a catalytic converter are arranged in the exhaust passage of the cylinder group to control the air-fuel ratio of the air-fuel mixture supplied to the first cylinder group based on the output signal of the first O 2 sensor . In a split operation type internal combustion engine, the air-fuel ratio of the air-fuel mixture supplied to the second cylinder group is controlled based on the output signal of the second cylinder group, and the supply of fuel to the second cylinder group is stopped during partial cylinder operation. An exhaust gas purification device for a split operation type internal combustion engine, in which a heater is disposed within two sensors and the heater is heated during partial cylinder operation.
