Embodiment Construction

[0049] figure 1 is a schematic block diagram of a prior art crankcase ventilation system 100 showing the flow paths of blow-by gas 170 and fresh air 160, figure 1 , the black solid arrows indicate the flow direction of the blow-by gas 170 , and the hollow arrows indicate the flow direction of the fresh air 160 . Such as figure 1As shown, the crankcase ventilation system 100 is a typical structure of a non-supercharger, and the crankcase ventilation system 100 in the present invention is not limited to this structure. The crankcase ventilation system 100 may generally include a crankcase 150 , an oil separator 140 , a PVC valve 130 , a breather hose 180 and an oil pan 190 . The reason for designing the crankcase ventilation system 100 is as follows: when the engine 320 is running, gas enters the crankcase 150 through the gaps between the cylinder wall, the piston and the piston ring, and the opening of the piston ring. This situation is generally called blow-by. 170 (Blowby)...

Abstract

The invention provides a heating system for engine oil, and belongs to the technical field of engines. The heating system comprises a temperature sensor, an engine oil delivery channel, a waste gas delivery bypass, a controller and an additional heat exchanger, wherein the temperature sensor is used for detecting the environment temperature; the engine oil delivery channel is used for delivering engine oil in an oil pan to an engine; the waste gas delivery bypass is used for delivering waste gas exhausted by the engine; the controller is used for selectively starting and stopping the waste gas delivery bypass according to the environment temperature; and the additional heat exchanger is connected into the engine oil delivery channel and the waste gas delivery bypass, and the additional heat exchanger is used for absorbing heat of waste gas and transmitting the heat to engine oil flowing through the additional heat exchanger in a heat exchange way when the waste gas delivery bypass started and is only used for delivering engine oil when the waste gas delivery bypass is stopped. By adoption of the heating system for engine oil, the problems that when a vehicle is in a short-distance traveling working condition for a long time in cold weather, emulsion of engine oil is generated, consequentially, abnormal abrasion of parts is caused, abnormal sounds can be made when abnormal abrasion is severe, and even a bearing bush gets stuck and starting is unavailable are solved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a heating system for engine oil. Background technique [0002] The role of engine oil in the engine is not only lubrication, but also cleaning, cooling, anti-corrosion and anti-rust functions. Once the oil is emulsified, its film formation will be greatly reduced, resulting in abnormal wear of friction pairs and affecting the life of the engine. [0003] In cold climates, the crankcase ventilation system is prone to condensed water. When the vehicle is driving for a short distance, the engine oil temperature is difficult to reach a high temperature state, so the condensed water in the crankcase ventilation system will accumulate in the crankcase ventilation system; in cold environments, long-term short-term As the distance travels, the water will gradually increase and the emulsification of the oil will occur; this will lead to abnormal wear of the parts, and in severe cases, it ...
