Combustion noise: structural vibration and noise of diesel fuel in the combustion process in the cylinder combustion noise level is very high, VDO water temperature sensor, however, higher engine structure in most parts of the steel, its natural frequency more in the high frequency region, because of the sound wave propagation frequency response does not match, VDO temperature wholesale, because they can not spread smoothly in the low frequency high peak cylinder pressure level, VDO temperature specials, while the high frequency cylinder pressure level is relatively easy to spread. When the water temperature sensor fails, often displayed cold start or hot car temperature signal, ECU not overly rich mixture to provide a signal supplied to the engine can only be compared with the thin mixture (hot car signals) , it is not easy to start the engine cold. This situation needs to check the water temperature sensor plug contact is normal or replace the water temperature sensor. For example: Read the car static engine (referring to the cold car) data found that the temperature of the engine coolant ECU output of 105 ℃, but this time (the set temperature in winter) the actual temperature of the engine is only 1 ℃, VDO water temperature, it is clear that the water temperature signal of engine ECU received is wrong, indicating a problem with the water temperature sensor VDO water temperature _ _ Zhongxin Electrical and Mechanical Production VDO temperature provided by the Dongguan City, South City Zhongxin Electrical and Mechanical operation. VDO water temperature _ _ Zhongxin Electrical and Mechanical Production VDO water temperature is Dongguan Nancheng Zhongxin Electrical and operating (zhongxin888.net.cn) this year introduced a new upgrade, the above picture is for reference only, please call the telephone or pictures on this page, for the latest Information, Contact: Miss Li.
