内燃機関の制御装置
Document Type and Number:
Japanese Patent JP4311441
Kind Code:
B2
Abstract:
An internal combustion engine control apparatus controls an internal combustion engine including: an exhaust passage including branch portions provided for the left and right banks and a common portion in which an exhaust gas purification device is provided; and a fuel supply system that supplies fuel to the respective engine cylinders. In the internal combustion engine, in order to recover the exhaust gas purification device, a bank control is executed in which the air-fuel ratio of the cylinders of the left bank is made rich while the air-fuel ratio of the cylinders of the right bank is made lean. The internal combustion engine is capable of running on alcohol-containing fuel and has an alcohol concentration sensor. The amount of unburned fuel to be supplied to the exhaust gas purification device during the bank control is adjusted based on the alcohol concentration in fuel.
