Development of New Technology and Composite Polymer Self-regulating Temperature Heating Materials and Components for Plastics Industry in Automotive Cold Start Application TAN Hong-sheng 12 WANG Ri-hui 2 LI Li 2 ZHENG Qiang (1 Department of Polymer Science and Engineering, Zhejiang University, Hangzhou 3100272, China Sinopec Qilu Co., Ltd. Resin Research Institute, Zibo, Shandong 255400) Heater, pass.
Diesel cold start and operation test. As can be seen from Table 3, the developed combination heater is heated in the condition of zero diesel wax (especially when the oil temperature is 7.8C wax), and the cold start and normal operation of the cold V power supply truck are very effective, and this is without heating. In the case of the device, it is impossible to achieve at all; in the case of wax-free heating (13 tests), although the cold start is successful, it is turned off after half an hour of operation. This is because a small amount of diesel components in the fuel tank have been waxed. After the ignition, during the oil supply process, the wax deposition section will aggregate in the oil-water separator to reach a certain amount and then block, stop, and extinguish. This, on the other hand, shows that the combination heater also plays a key role in the normal operation of the truck. In the case of proper use of the heating device, the above test shows that the car battery power supply is sufficient to meet the requirements of using the heater and ignition start.

The combined heater developed can meet the requirements of cold start of diesel vehicles in winter, indicating that composite polymer self-limiting temperature heating materials and components are applicable to the automotive field.
