Abstract

The invention discloses a control method and system for an electric-control water pump of an engine. By the adoption of the control method and system for the electric-control water pump of the engine, the defects that in the prior art, the cooling effect is poor under a large-torque area working condition, the effective specific fuel consumption is high under a speed regulating area working condition, and in-time heat dissipation cannot be achieved under a halt working condition can be overcome. The control method comprises the steps that the temperature data of cooling water in the position where a temperature sensor is located are collected through the temperature sensor which is arranged in the center of a water outlet pipe of a cooling water radiator corresponding to the electric-control water pump to be controlled of the engine; the temperature data collected by the temperature sensor are obtained through an electronic control unit (ECU) , and the working condition of the engine is determined by processing the temperature data, and the rotating speed of the electric-control water pump is regulated to be increased if the working condition of the engine is the large-torque area working condition, or the rotating speed of the electric-control water pump is regulated to be decreased if the working condition of the engine is the speed regulating area working condition, or the electric-control water pump is controlled to operate for a preset period of time if the working condition of the engine is the halt working condition.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a method and system for controlling an electronically controlled water pump of an engine. Background technique [0002] At present, electronically controlled engines have been widely used, and have shown advantages over traditional mechanical pump engines in various aspects, but most electronically controlled engines still use mechanical water pumps. The flow rate of the traditional mechanical water pump (driven by the crankshaft through the transmission belt) is only proportional to the speed and has nothing to do with the size of the load, resulting in the following traditional disadvantages: near the speed of the high torque point in the external characteristics, due to the decrease of the engine speed, the flow rate of the water pump decreases. The cooling effect becomes worse. At this time, the heat load of the engine is relatively large, which leads to an increase in the te...
