CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE

摘要

Control apparatus for internal combustion engine in which alcohol fuel can be used includes: acquisition unit for acquiring alcohol concentration of fuel; electric motor for driving internal combustion engine; and a control unit configured to control the internal combustion engine and the electric motor. The control unit is configured, when the running time from a low-temperature start to the stoppage of the internal combustion engine or a parameter increasing with an increase of the running time is equal to or lower than a predetermined value, to cause, after the stoppage of the internal combustion engine, the electric motor to subject the internal combustion engine to motoring and to set the motoring time of the motoring to be shorter when a fuel alcohol concentration acquired by the acquisition unit is relatively high compared to when a fuel alcohol concentration acquired by the acquisition unit relatively is low.

1. A control apparatus for an internal combustion engine in which alcohol fuel can be used, comprising:
an acquisition unit for acquiring an alcohol concentration of fuel; an electric motor for driving the internal combustion engine; and a control unit configured to control the internal combustion engine and the electric motor, wherein the control unit is configured, when the running time from a low-temperature start to the stoppage of the internal combustion engine or a parameter increasing with an increase of the running time is equal to or lower than a predetermined value, to cause, after the stoppage of the internal combustion engine, the electric motor to subject the internal combustion engine to motoring and to set the motoring time of the motoring to be shorter when the alcohol concentration of the fuel acquired by the acquisition unit is relatively high compared to when the alcohol concentration of the fuel acquired by the acquisition unit is relatively low.
