The waste gas of case and the mixture of engine oil can be directly discharged in environment by a pressure-reducing valve.If crankcase is not logical
Wind, its internal pressure can constantly increase when engine works, and engine may finally be caused to cast anchor.Due to crankcase discharge
Waste gas contains harmful composition, especially nitrogen oxides, has been used at present in Europe for the ventilating system of crankcase closing
New exhaust emission regulations（The Euro3 of in September, 2014 issue is to 6 standards）.When temperature is less than 4 degree, in crankcase waste gas
The moisture contained（Due to Water vapor condensation）Icing phenomenon occurs, causes a certain degree of block up occurs in crankcase ventilation system
Plug, at this moment crank case vent heater just arises at the historic moment, and a strength is made for environmental protection, especially for diesel engine
For, its waste gas circulation control has become the important means for reducing discharged nitrous oxides.Crankcase heater would generally pacify
Mounted in specified location.Here, the waste gas of crankcase can be incorporated into the position of internal combustion engine intake fresh air, if crankcase adds
Hot device joint is surprisingly come off, then crankcase waste gas can be caused to be directly discharged into air, pollutes environment, admission line therefore gas leakage, mistake
More air are mixed into engine, dilute gas mixture, and therefore engine power also declines, have such regulation in America ＆ Canada：
It must detect whether crankcase heater has connected by diagnostic system.The principle of work and power of crankcase heater is to convert electrical energy into
Heat energy, its process are completed by the core of heater, it is also necessary to are used PTC thermistor, passed heat by thermistor
To heat-conductive assembly, and then it is transported to need air intake position to be heated.
Traditional crankcase heater is connected, complicated, installation inconvenience more using circuit, and attachment structure cloth with thermal source
Office is unreasonable, and fault rate is high during use.
