摘要：
A control system for an internal combustion engine for use in a vehicle. An ECU determines whether the catalytic converter is in a predetermined high temperature condition, and also determines whether the engine has continuously been in an operating condition in which the rotational speed of the engine exceeds a predetermined value and load on the engine exceeds a predetermined value, over a predetermined time period. When the catalytic converter is in the predetermined high temperature or when the engine has continuously been in the above high speed and high load condition over the predetermined period, the ECU controls the throttle valve in a manner such that the opening of the throttle valve is decreased.
