Controller of vehicle internal combustion engine

摘要

A controller of a vehicle internal combustion engine that is automatically stopped and restarted under a prescribed condition related to operation of the vehicle is disclosed. The engine includes an output shaft, a starter constantly meshed with the output shaft, and a throttle valve regulating the intake air amount supplied to the engine. After the engine has been subjected to an automatic stopping procedure, the controller restarts the engine when a restarting condition is met, and the controller uses the starter to restart the engine if the engine speed is in such a predetermined range that autonomous operation of the engine cannot be restored. The controller predicts, as a predicted air amount, the amount of air drawn into the cylinder of the engine after the restarting condition is met. The controller reduces an engine start fuel injection amount, which is calculated when the starter is used, in correspondence with the predicted air amount.
