Problems solved by technology

However, this method only passively closes the oil cooling nozzle, and relies on combustion to generate heat to preheat the piston to increase the operating temperature of the engine, and cannot automatically control the operating temperature of the engine. It is preheated, causing the viscosity of the engine oil to increase, making it difficult to lubricate the various parts of the engine, resulting in increased engine running resistance

Embodiment Construction

[0071] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0072] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0073] see figure 1 , the embodiment of the present invention provides an engine temperature control system, including a parameter acquisition unit 1, an electronic control unit 3 and a heating unit 4;

[0074] The parameter collection unit 1 is used to collect engine operating parameters to send to the electronic control unit 3;

[0075] The electronic control unit 3 is used to store preset operating parameters, and when the ratio of the engine operating parameters to the preset operating parameters is less than the threshold value δ, an opening instruction is sent to the heating unit 4; when the ratio of the engine operating parameters to the preset operating parameters is greater tha...

Abstract

The invention provides a temperature control system for an engine, and a control method thereof, relates to the technical field of engine control, and aims at automatically adjusting the working temperature of the engine in the case of cold start-up or low-temperature running of the engine, thereby improving the working performance of the engine. The temperature control system for the engine comprises a parameter acquisition unit, an electronic control unit and a heating unit, wherein the working parameters of the engine are acquired through the parameter acquisition unit, the ratios of the working parameters of the engine to preset working parameters, are compared with a threshold value delta through the electronic control unit to obtain corresponding instructions, the turn-off and turn-on of the heating unit are controlled to automatically control the temperature of engine oil located in an oil channel of an engine oil nozzle, and the piston is heated by virtue of the heated engine oil to raise the working temperature of the engine. The temperature control system for the engine is used in the technical field of engine control.

Description

technical field [0001] The invention relates to the technical field of engine control, in particular to an engine temperature control system and a control method thereof. Background technique [0002] The engine is a power conversion system that provides power for the car, and its operating temperature determines the performance of the engine. Moreover, an oil cooling nozzle is also arranged in the engine, on the one hand to cool down the working piston in the engine, and on the other hand to lubricate the various parts in the engine to reduce the wear of the various parts in the engine and improve the service life of the engine . [0003] At present, when the engine is cold started or running at low temperature, the oil cooling nozzle of the engine has been opened to cool down the piston. At this time, the operating temperature of the engine is relatively low, and it is difficult to reach the optimal operating temperature for a long time. When the operating temperature of...
