ADVANCED ELECTRICAL COOLING FAN CONTROL SYSTEM
In front-wheel drive vehicles which cool the radiator by a motor driven fan there is a tendency for engine cooling water heat dissipation to increase because of increases in engine output and increased capacity. On the other hand, maintaining the cooling air flow by improving the performance of fan systems has become very important where there is a tendency for the cooling air flow of the radiator to drop during motoring as the area of the cooling air inlets and height of front ends are being restricted by style and wind resistance capabilities. In the new Nissan Bluebird a new cooling system has been employed which controls the fan speed via the engine control unit making it possible to achieve optimum fan control by taking account of not only water temperature but also the vehicle driving conditions. At the same time this system reduces the cost of cooling systems by using fewer components compared to conventional systems. The paper gives an outline of the cooling system.
