Abstract

The invention discloses an engine oil filtering, cooling and preheating integrated system and method. The system comprises a filtering submodule, a cooling submodule, a preheating submodule and an oil path switch submodule, wherein the preheating submodule comprises a main module body, an exhaust inlet / outlet pipe and an exhaust circulating pipe; an engine oil inlet / outlet is arranged at the bottom of the main module body; the filtering submodule is connected with an oil sump through an engine oil pump; the input end of the oil path switch submodule is connected with the filtering submodule; and the oil path switch submodule can intelligently choose to trigger engine oil heating or engine oil cooling according to the engine oil temperature. The system provided by the invention has the advantages that engine oil can be filtered, cooled and preheated; the integrated degree is high, the operation is reliable, and energy conservation and environmental protection are achieved; according to the working condition requirements, the engine oil temperature can be managed to remain in the optimum state; and therefore, the engine heating period is shortened, the engine cold-starting performance is improved, and the friction loss and the abrasion of engine parts are reduced.

Description

technical field [0001] The invention relates to the field of engines, in particular to an engine oil filtering, cooling and preheating integrated system and method. Background technique [0002] In the case of cold start of the engine, especially in cold seasons, due to the high viscosity of the engine oil and the low temperature of the water, it leads to higher emissions and fuel consumption during the start-up phase. Usually, it takes about 10 minutes for the vehicle to warm up from the engine to its optimum operating temperature, and at this stage due to the high viscosity of the engine oil and the poor operating temperature, the fuel consumption increases by as much as about 9%. When the engine oil is viscous, it is easy to cause bearing wear, which affects the life of the engine. At present, the effective utilization rate of fuel for automobiles can only reach one-third, and the rest of the energy is discharged into the atmosphere through different forms such as coolin...

Problems solved by technology

[0002] In the case of cold start of the engine, especially in cold seasons, due to the high viscosity of the engine oil and the low temperature of the water, it leads to higher emissions and fuel consumption during the start-up phase

Usually, it takes about 10 minutes for the vehicle to warm up from the engine to its optimal operating temperature, and the fuel consumption at this stage is even as high as about 9% due to the high viscosity of the engine oil and poor operating temperature.

When the engine oil is viscous, it is easy to cause the wear of the bearing bush, thus affecting the life of the engine

At present, the effective utilization rate of fuel for automobiles can only reach one-third, and the rest of the energy is discharged into the atmosphere through different forms such as cooling medium heat dissipation and exhaust emissions, which has a certain impact on the environment and also caused a waste of energy.

[0003] In order to reduce the impact of ambient temperature on the engine, the traditional way is to install the heating device on the engine separately, but this will limit the structure, volume, process conditions, etc. Corresponding increase, lower assembly efficiency

At present, the engine and the heating device are connected through pipelines, the overall structure is complex, oil leakage, water leakage and other phenomena are prone to occur, and there are many fault points, which affect the reliability of the engine

At the same time, the cooling, filtering and preheating of engine oil in the prior art lack relevance and continuity, and the heating efficiency of engine oil is low and the heating effect is not obvious, which seriously affects the normal operation of the engine
