Engine oil outer cooling and circulating system of engine

Abstract

The invention relates to an engine oil outer cooling and circulating system of an engine. The engine oil outer cooling and circulating system comprises a constant-temperature control mechanism for performing constant-temperature control on engine oil, wherein an oil inlet of the constant-temperature control mechanism is communicated with an oil outlet of a filter base of the engine through an oil inlet tube, and the oil outlet is communicated with an oil return port of the filter base of the engine through an oil outlet tube. The constant-temperature control mechanism comprises a temperature master control unit, a temperature detection mechanism and a cooling mechanism, wherein standard values of the temperature of the engine oil of the engine are stored in the temperature master control unit; the temperature detection mechanism is used for detecting the temperature of the engine oil in real time, is arranged in the oil outlet tube and can instantly transmit the detected engine oil temperature to the temperature master control unit connected with a signal output end of the temperature detection mechanism; the cooling mechanism is used for cooling the engine oil and receives control signals emitted by the temperature master control unit to cool the engine oil under different engine operation conditions by adjusting the flow and speed of self cooling liquid. The engine oil outer cooling and circulating system is simple in structure, can effectively ensure the temperature of the engine oil flowing into the engine, simultaneously ensures the pressure of the engine oil flowing into the engine, provides good operation environments for the engine and is suitable of engines of various vehicles.

Description

technical field [0001] The invention relates to a vehicle engine, in particular to an engine oil cooling system, in particular to an engine oil external cooling circulation system. technical background [0002] The engine is the core component of the vehicle. During the developmental test, the engine oil will continue to heat up due to the engine running and the load increasing. In order to ensure the engine's operating performance, it is necessary to cool down the engine in the test. [0003] In the prior art, a cooler is generally integrated on the engine, and the engine oil is cooled by the cooler, but this cooler integrated on the engine body has the following defects: [0004] (1) Small size: Since the cooler is integrated on the engine, and the engine needs to be installed on the vehicle, due to the limitation of the layout space of the vehicle, the cooler can only be made very small, resulting in cooling of the engine by the cooler the effect is not very good; [00...

AI Technical Summary

Problems solved by technology

[0004] (1) Small size: Since the cooler is integrated on the engine, and the engine needs to be installed on the vehicle, due to the limitation of the layout space of the vehicle, the cooler can only be made very small, resulting in cooling of the engine by the cooler the effect is not very good;

[0005] (2) The initial temperature of the coolant is relatively high: since the cooler uses the coolant of the engine cooling cycle system to cool the engine, and the coolant is limited by the thermostat, the initial temperature of the coolant is relatively high, which does not meet the requirements. The cooling temperature requirements when the engine starts, resulting in poor performance when the engine starts;

[0006] (3) Uniformity of use of the cooler: Since the cooler needs to match the overall structure of the engine, oil pump and other components at the beginning of the design, different engine models cannot be used universally or interchangeably. Therefore, once cooled If the cooler fails, the designated cooler needs to be replaced, while other coolers cannot be used, resulting in the monopoly of various manufacturers on customers

[0007] (4) The oil pressure at the oil inlet and outlet of the cooling circulation system is inconsistent, resulting in pressure loss after the oil flows in the cooling circulation system, which cannot guarantee sufficient oil pressure for the engine
