| 发明名称 | Control system having variable-speed engine-drive fan | ||
| 摘要 | A control system for use with a machine having an engine is disclosed. The control system may have a cooling circuit, a heat exchanger associated with the cooling circuit, and a sensor configured to generate a signal indicative of a temperature of the cooling circuit. The cooling system may also have a fan mechanically driven by the engine to direct air through the cooling circuit, and a controller in communication with the sensor and the engine. The controller may be configured to adjust a speed of the engine based on the signal. | ||

| 主权项 | 1. A control system for a machine having an engine, comprising: a cooling circuit; a heat exchanger associated with the cooling circuit; a sensor configured to generate a signal indicative of a temperature of the cooling circuit; a fan mechanically driven by the engine to direct air through the heat exchanger; and a controller in communication with the sensor and the engine, the controller configured to adjust a speed of the engine based on the signal by adjusting fueling of the engine by an amount related to a desired seed of the fan. | ||
