Embodiment Construction

[0027] A kind of engine preheating method, it comprises following process:

[0028] Preparation Phase:

[0029] The first step is to power on the vehicle, initialize and process;

[0030] The second step is to collect the water level of the water tank; judge whether it is necessary to replenish the coolant, and display it on the screen in the cab, and replenish it in time if necessary;

[0031] The third step is to collect the ambient temperature and judge whether the engine needs to be warmed up; if the next step is required, start the engine directly;

[0032] Preheating process:

[0033] In the fourth step, if preheating is required, the preheating system is turned on through two electromagnetic reversing valves, and the cooling system is turned off;

[0034] The fifth step is to turn on the electric heater and the water pump to heat the coolant; the electric heater is used to heat the coolant, and the water pump is used to circulate the coolant in the system.

Abstract

The invention relates to the technical field of engines, in particular to an engine preheating method and system. The system involves an engine, an electric heater, a water pump, an engine cooling system and a water tank, wherein the electric heater, the water pump, the engine cooling system and the engine communicate through cooling liquid pipelines, the electric heater and the water pump side cooling liquid pipeline form an engine preheating system, a first electromagnetic conversion valve and a second electromagnetic conversion valve are installed on the two sides of an engine correspondingly, the engine cooling system and the preheating system communicate with different electromagnetic conversion valve positions correspondingly, the water tank is installed between the first electromagnetic conversion valve and the electric heater to supplement water to the engine preheating system, a water level sensor is mounted on the water tank, and a normally open electromagnetic valve and a temperature and water level sensor assembly are mounted on a water supply pipeline for connecting the water tank with the electric heater. The system is simple in structure, easy and convenient to operate, high in efficiency and capable of effectively solving the problems that an engine is difficult to start and large in abrasion in winter.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine preheating method and system. Background technique [0002] In winter, the ambient temperature is low, the fluidity of the lubricating oil in the engine is poor, the frictional resistance between the parts is large, the engine is difficult to start and the engine wears out. Therefore, a vehicle that has been parked for a long time needs to be preheated when it is started. When the temperature of the engine reaches a certain temperature before starting, the performance of the vehicle can reach the best state. The traditional engine warm-up system has a complex structure and a long warm-up time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an engine preheating method and system with simple structure, easy operation and high efficiency, which can effectively solve the problems of difficulty in starting the ...
