Abstract

The invention discloses an oil way preheating system of a diesel engine. The diesel engine comprises a diesel tank, a diesel pipeline, a diesel filter element and a fuel pump, wherein an electronic booster pump is additionally arranged on the diesel filter element; heating elements are correspondingly arranged in the diesel tank, in the diesel pipeline and outside the diesel filter element; the heating elements and the electronic booster pump are connected with a control switch; and the control switch is connected with a power supply. The invention further discloses a preheating method. The preheating method comprises the following steps: firstly, diesel in the diesel tank, the diesel filter element, a first pipeline and a second pipeline is preheated; when wax-deposited diesel in a precipitation cup of an oil-water separator is changed to a normal color, the heating is stopped; the gear of the control switch is switched; the electronic booster pump starts to work; the preheated dieselis pumped to the fuel pump; the fuel pump pumps the diesel back into the diesel tank; and the cyclic heating is performed. The preheating system and the preheating method can effectively solve the problem of difficult starting of the diesel engine, and meanwhile, can prolong the service life of the fuel pump through adding the fuel filter element to reduce the cost.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to an oil circuit preheating system of a diesel engine and a preheating method thereof. Background technique [0002] When the construction site of the engineering project is located in a high altitude or cold area, it is difficult or impossible to start the diesel engine due to the low temperature. For example, the Pakistani market cannot provide equipment power diesel suitable for low-temperature climates. In winter, the phenomenon of diesel freezing and waxing will occur, resulting in the failure of normal start-up and operation of equipment. Contents of the invention [0003] The object of the present invention is to provide an oil circuit preheating system and a preheating method for a diesel engine, which can avoid the occurrence of freezing and waxing of diesel oil in the fuel tank, and solve the problem of difficulty in starting the diesel engine in cold winter weat...
