Abstract

The invention relates to the field of automobile control technologies, and in particular relates to an engine temperature adjustment system and an engine temperature adjustment method. The system comprises an engine, a thermostat, a main water tank and a first water pump. The system also comprises a second water pump, a controller, an ignition lock electrically connected with the controller, and a temperature sensor, wherein the second water pump is connected with the first water pump in parallel, pipelines from the thermostat to one end of the second water pump and from the other end of the second water pump to the first water pump are covered with heating wires controlled by the controller, the temperature sensor is installed between a water outlet of an engine and the thermostat; the controller controls the second water pump and the heating wires to work according to an ignition lock signal and a temperature sensor signal, and thus the engine preheats in advance before start, and the work temperature of the engine after start is normal. According to the system and the method provided by the invention, automatic adjustment of the engine temperature is achieved, and work reliability of the engine is improved.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to an engine temperature regulating system and method. Background technique [0002] It is generally difficult for traditional vehicles to start in the cold season. One of the reasons is that the temperature of the engine block is low after being left overnight. At this time, the oil-air mixture enters the block and is difficult to burn. [0003] When driving in summer, for some heavy-duty vehicles, if they climb uphill frequently, the water temperature will be too high. At this time, if you continue to drive, it is very easy to have a "boiling" fault. The correct way is to park the car and let the engine run at an idle speed. , until the water temperature drops below the safe temperature. [0004] Specifically, such as figure 1 Shown is a truck engine temperature regulation system in the prior art, including: engine 1', water pump 2', temperature sensor 3', radiator ou...
