The starting methods of
Cummins generator set in low-temperature environments mainly include the following:
1. Use diesel engine oil with good low-temperature performance: In low-temperature environments, it is recommended to use 10W or 5W engine oil because these oils have lower viscosity at low temperatures, good lubrication effect, low starting resistance, and are conducive to starting.
2. Use batteries with good low-temperature performance: If necessary, the battery can be insulated to ensure that it can be charged normally under low-temperature conditions and has sufficient output current, thereby increasing the power of the starting system.
3. Spray low-temperature starting fluid: The starting fluid has a low ignition point and can quickly ignite at low diesel engine speeds, thereby igniting the diesel in the combustion chamber to achieve starting. A certain amount of starting fluid can be sprayed into the intake pipe before starting.
4. Install a heating device: Install a heating device on the intake pipe to heat the intake air with electrical energy, increasing the gas temperature inside the cylinder at the end of compression, which helps with low-temperature starting.
5. Heating and cooling medium: By heating and cooling the medium, the diesel generator set can be started normally in an environment below -40 degrees Celsius.
6. Circulating water heating: The coolant is heated by a fuel heater and circulated back to the engine, raising the temperature of the engine body and oil, reducing viscosity, and enabling smooth start-up at low temperatures.
7. Flame preheating start: Use a flame preheating device to heat the electric plug to a certain temperature and then turn on the starter to start the flame preheating, suitable for extreme low temperature environments.
These methods can effectively help Cummins generator sets start smoothly in low-temperature environments, ensuring the normal operation of the equipment.
