Abstract
To minimize excessive temperature elevation when in a fast idle state for an engine covered with a cowling, and to prevent heat damage to the cowling, for motorcycles. A radiator and an electric radiator fan are positioned ahead of a watercooled engine and are installed inside a cowling C. When a transmission neutral sensor detects when the transmission is in neutral and a engine speed sensor detects a speed at or over a fast idle speed of the engine both output a high-level signal continuously for a specific length of time to a timer. This state is recognized as the fast idle state of the engine, the transistor is switched on, and the electric motor of the radiator fan 17 is actuated.
