www.chinabuses.org: Recently Foton AUV released their 3rd generation e-AIR Engine Intelligence Cooling System after many year development, and there are thousands of Foton AUV buses equipped with e-AIR Engine Intelligence Cooling System to ensure perfect matching of working process and engines and the bus can save 5% fuel every 100 km.
It is learned that e-AIR Engine Intelligence Cooling System can monitor the temperature of the engine in working conditioner in real time and it can also control the switch and rotational speed so that the engine can always work in the best temperarure.
Traditional engine cooling system adopts V bend or hydraulic motor to get power from engine and the e-AIR Engine Intelligence Cooling System adopts intelligent electric fan to make the best use of the energy. The average rotate speed for bus engine is 2000rpm, and the transmission ratio is 1.2-1.5, and the electric fan will consume 10kW or more, taking 10% of the power for the engine, but e-AIR Engine Intelligence Cooling System can consume about 2.5kw.
The traditional bigger electric fan will generate larger noise and vibrate, and smaller electric fan is used for the e-AIR Engine Intelligence Cooling System, and the noise can be reduced for 2-4 decibel.
The best temperature for the enigne is between 85-95 C, and the e-AIR Engine Intelligence Cooling System integates Real-time temperature sensing system, CAN information control system, ECU Electronic information processing system and Electronically controlled air terminal to make sure that the temperature is between 85-95 C.
