On cold start the diesel engine air compressor

Northern or western China's plateau in winter, due to lower ambient temperature, difficulty in starting air compressor machinery. The main reason is: the end of compression cylinder diesel engine air compressor air temperature of less than the required starting temperature, air pressure inside the cylinder and significantly lower than the required starting pressure; optimum operating temperature of the battery 20 ~ 40 ¡æ, with the ambient temperature decreased, the corresponding decline in output capacity, resulting in decreased engine power air compressor start system; the ambient temperature is low, the oil viscosity becomes large, the friction between the negative resistance is increased, the diesel engine air compressor start slowing down, while increasing the viscosity of diesel, fuel injector spray quality deterioration, extending the ignition lag period; air density and oxygen content in air increases with altitude decreases, the higher the altitude, engine air compressor machine more difficult to start.

       At low temperatures, in order to ensure all kinds of construction machinery in cold conditions can be safely put into use, should be doing routine maintenance, preferably with a cold start assist system.

Several common low-temperature start-up mode:

       (A) a good selection of low-temperature performance of diesel engine air compressor oil air compressor oil low temperature viscosity of such a small, good lubrication between the friction, starting resistance, which will help to start. The current multi-grade oil, such as the smaller figures before 15W/40W low-temperature oil flow, the better. Therefore, the low temperature recommended 10W or 5W oil.

      (B) a good low temperature performance of batteries, the battery may be necessary, Airbrush insulation, low temperature conditions to ensure that its charge properly and there is sufficient output current, thereby increasing the power of your system.

(C) filling the cold start solution

(D) flame preheat start

      (E) circulating water heating systems (also known as fuel heater system)

      (Lu) Other methods of preheating

In addition to the warm-up mode, the method can be applied to preheat hot water, steam warm-up Mini air compressor method, electric preheating method and other methods for low temperature starting.
