Abstract

A throttle management apparatus for an internal combustion engine is provided which allows the response of the engine to an operator's request to be improved while allowing the output characteristic of the engine to be controlled arbitrarily. The throttle management apparatus controls plural throttle valves provided for plural cylinders respectively. The throttle management apparatus includes an electric throttle management apparatus which electrically drives the throttle valves for some of the cylinders based on an electric signal generated according to selected operating conditions of the vehicle, and a mechanical throttle management apparatus which, through throttle activation member operation, mechanically drives the throttle valves for the rest of the cylinders. In an engine having a V type cylinder head configuration, the electric throttle management apparatus controls the throttle valves of one cylinder bank of the cylinder bank pair, while the mechanical throttle management apparatus controls the throttle valves of the other cylinder bank.
