Vehicle rooftop engine cooling system
First Claim
1. A method of using an engine cooling system with a bus including a rooftop and an engine in an engine compartment for propelling the bus, the engine including a passage for allowing coolant to flow there through for cooling the engine, the method comprising:
- providing a horizontal rooftop engine cooling system including a radiator unit through which coolant fluid flows for removing heat from the radiator unit, a fan to assist in removing heat from the radiator unit, and a continuously variable power drive and speed control system for controlling power to and the speed of the fan;
horizontally locating the rooftop engine cooling system on the rooftop of the bus;
interconnecting the radiator unit of the rooftop engine cooling system to the passage of the engine to allow coolant to flow between the engine and the rooftop cooling system to cool the engine;
controlling power to and the speed of the fan with the continuously variable power drive and speed control system using pulse width modulation.
