[0033] 1A to 2 show a first embodiment of the present invention. Specifically, FIGS. 1A to 1C are schematic diagrams showing the overall structure of a rotation angle detecting device. Fig. 2 is a modification showing the main structure of the rotation angle detecting device.
[0034] The internal combustion engine control system (engine control system) according to the present embodiment includes an electronically controlled fuel injection system, an intake module (intake air amount control device), and an engine control unit (ECU). The electronically controlled fuel injection system injects fuel into a combustion chamber of an internal combustion engine of a vehicle, such as a motorcycle (for example, a single-cylinder four-cycle gasoline engine for a motorcycle, hereinafter referred to as an engine). The intake module is coupled to the intake system of the engine. The ECU controls the electronically controlled fuel injection system and intake module.

[0099] 3 to 5 show a second embodiment of the invention. Specifically, FIG. 3 is a schematic diagram of an air intake module, wherein the air intake module has a rotation angle detecting device according to a second embodiment. Fig. 4 is a schematic diagram showing an intake air temperature detector according to a second embodiment. Fig. 5 is a schematic diagram showing an intake module pressure detector according to a second embodiment.
[0100] The intake module of this embodiment includes a rotation angle detection device (see the first embodiment), an intake air temperature detector 6 and an intake module pressure detector 7 . The rotation angle detection device includes a magnet 2, a throttle opening degree detector 3 and an open yoke. The intake air temperature detector 6 measures the temperature of intake air supplied to the combustion chamber of the engine (intake air temperature). Then, the intake air temperature detector 6 converts the measured intake air temperat...
