This is to heat the oil pipeline in the car or mechanical equipment, so as not to freeze and block the oil pipeline in the cold season (or region), I recommend using an electric mattress heating wire to wrap around the outside of the oil pipe, and then wrap a protective layer on the outside, which is not safe to put directly in the oil pipe. The temperature should not be too high, just keep it not frozen! Just a suggestion, the electric mattress wire is 220V, just cut a quarter to maintain the temperature, there is a temperature but will not burn red, please be sure to pay attention to safety! Try to do it, the longer the electric mattress wire, the lower the temperature, on the contrary, the higher the temperature!
It is also possible to directly wrap insulation materials outside the oil pipe, filter, and oil circuit switch position, but the effect is slightly worse!
