1. Speed ??combustion stage from the beginning to the fire at this stage maximum pressure occurs when the cylinder ended. When a small amount of diesel fuel on fire, combustible mixture continued to increase fire quickly spread, burning speed, heat release rate is high. Pressure and temperature inside the cylinder dramatically. But the pressure rises too fast VDO sensor, crank linkage would severely impact loads, and with a sharp percussion specialty sensors, diesel engine explosion rough, this situation should be restricted. For the diesel engine working smoothly sensor wholesale, the growth rate should not exceed the maximum pressure 292kPa ~ 588kPa / 1 ° (crank angle) is detected in the engine water temperature is low, the water table water temperature information ECU's temperature sensor input air-fuel ratio becomes rich, so that the engine ran smoothly, if this time the water temperature sensor cold state information sensor does not occur, it will make the air-fuel ratio becomes lean, causing the engine does not operate properly. Similarly, if the warm-cold issue information, then allow air-fuel ratio becomes rich, the engine is not normal. VDO sensor _VDO (Online) _ sensor provided by the Dongguan City, South City Zhongxin Electrical and Mechanical operation. Dongguan Nancheng Zhongxin Electrical and operating (zhongxin888.net.cn) Dongguan, Guangdong, industrial products leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Zhongxin Electrical and Mechanical leadership with the staff warmly welcome all inquiries negotiations to create a better future for electromechanical faithful.
