Abstract
The engine cooling system is required to provide much higher performance today owing to the improved power output of engines and the trend toward a more compact engine compartment. For front engine/rear drive vehicles equipped with a fluid coupling drive fan, one of the main problems that must be dealt with is the rise in coolant temperature during idling. This paper presents a new method to simulate the engine coolant temperature under idling condition, and an improved engine cooling system that features a totally redesigned fan blade for maximum efficiency. This new system, consisting of a high performance cooling fan shroud and coupling, achieves a substantial noise reduction and contributes to fuel economy and power output improvements.
