The first effect of the water temperature sensor is through relatively simple changes in its internal resistance to be achieved by varying the current variation through the resistor to drive the change in water temperature sensor changes indirectly tell people of the engine operating temperature. The second category, there is no change in the water temperature sensor in terms of structure, but its role is to provide an engine control unit temperature change analog signals. It is supplied by the supply voltage 5V power supply control unit, the control unit returns the signal to a linear change signal of 1.3V-3.8V. The main role is to tell the temperature of the engine control unit now how much. Conversely it is a signal to the control unit and its importance. The main engine work differently under different operating temperatures. For example: 86 degrees below the normal temperature of the engine more than 10 percent of jet fuel, the purpose is to allow the engine to rapid heating to reduce cold engine wear. The temperature rose to 86 degrees and then let the engine a little less spray oil, a little slow to make the temperature of regeneration. So its role is very important. If he had had a problem, the engine control unit provides the wrong signal, such as in a hot car engine provides a low signal to your car if it's more than a little spray oil, the generator sensor special, so it becomes a little oil La. The best recommendations for future oil room building following options: Minimize the number of oil engine room doors and windows, a generator sensor, avoiding oil leakage noise machine; try to increase the oil from the engine room air inlet from oil-based, VDO generator sensor, extending from the silencer, production generators sensor, the best building air intake chamber; increases in aircraft exhaust estuary and try to extend the expansion chamber exhaust expansion chamber from the oil-room, five-room addition to the ground wall can be used acoustic treatment, the use of perforated plate resonance absorption structure according to the spectral characteristics of the generator set.
