To start the way Cummings generator under low temperature

As everyone knows Cummings generator under the condition of low temperature cooling is excessive, leading to not start. But in the environment of low temperature is not can not start, there are other startup mode.
(1), hot water preheating method
Still can use hot water preheating method (heat to boiling point of the hot water injection cooling system) steam preheating method (steam through the pipeline from the water tank under the water pipe enters the cooling system, or directly into the cooling water jacket of engine), electric preheating method (the heater directly into the cooling system or oil, the heat efficiency is high, the power generation unit the utility model is used) and many other methods to start at low temperature.
(2), circulating water heating system (also known as the fuel heater heating system)
This is the low temperature auxiliary starting new ways adopted in recent years, the low temperature starting way is through the fuel heater attached to the engine coolant pump the body out, through the fuel heater heats then recirculated to the engine body, thereby heating the engine, to achieve the purpose of starting the engine under the condition of low temperature.
(3), cold starting liquid filling
Cold starting fluid is a kind of auxiliary starting fuel (hydrocarbons of low volatilization point and low pour point oil with additives composition), one with additive can improve the low pour point oil cylinder wall lubrication conditions, achieving the purpose of starting. Select start the boot, should better starting liquid atomization, and good control of injection blowing position and spraying amount of time. In addition, avoid starting fluid into the inlet air filter from the direct injection, so as not to affect the quality of the filter elements and increase the lifting liquid injection quantity, cause the engine cold start running speed.
(4), flame preheating
The lowest work temperature flame preheating device is -40 Deg. C, working process of electronic automatic control. Flame preheating starting device generally by the electronic controller, an electromagnetic valve, a temperature sensor, a flame preheating plug and fuel pipe and wire. The working process of the device is, the electro thermal plug heating to 850-950 deg.c on starter, automatic open circuit of electromagnetic valve, to supply the electric plug through the fuel tube, flame preheating.
Usually in the environment of low temperature Cummings generator can take several ways to the start.
