Locomotive starting difficulty in winter, a tile burning with oil?
Low winter temperatures, inside the battery electrolyte viscosity increases, the resistance increases, the permeability variation, and thus a significant reduction in the voltage of the capacity and, starting not enough electricity, the output function declines reach the starting speed requirements.
Low winter temperatures, gas viscosity increases, evaporation variation, atomization, the concentration of the mixture is difficult to achieve can ignite make starting difficult.
High in winter because of the use of lubrication oil pour point, low temperature flow is poor, dynamic viscosity at low temperature is higher than the national standard, such as 10 w / 30 oil, pour point - 30 ℃. Pumping temperature 25 ℃, dynamic viscosity at low temperature is not more than 3500 mpa/s. If the temperature below 25 ℃, using 10 w / 30 oil starting has been difficult, some people in the pour point - mistaken for temperature 30 ℃. In more than pumping temperature Degrees (- 26-29 ℃) and forced starting car, would be a tile burning phenomenon, so special attention should be paid to in the winter it is better to handle before starting rocking-turn crankshaft 10-20 laps, good lubrication, both for the engine parts and then start the engine, so easy to start, and can reduce the wear and tear.
Winter often do so can prolong the life of the engine and battery. Winter is the best to the rolls of parking, can avoid caused by starting the engine.
Suggest winter temperatures below 45 ℃ - use 0 w / 30 viscosity
- select 5 w / 30 viscosity below 30 ℃
- below 25 ℃ to choose 10 w / 30 viscosity
