Embodiment Construction

[0013] The invention discloses a method for recovering and utilizing waste heat of lubricating oil of an internal combustion engine. The lubricating oil in the inner oil pan of the engine is connected to a double-layer vacuum insulation container through a pipeline of a miniature DC pump. When the internal combustion engine stops working for a period of time, the micro DC pump will guide the lubricating oil in the oil pan into the double-layer vacuum insulation container. Since the lubricating oil in the water tank is in a high temperature state when the internal combustion engine is working, the waste heat generated by the internal combustion engine will be absorbed. Stored in a double-layer vacuum insulation container to achieve the purpose of recovering the waste heat of the internal combustion engine lubricating oil; when the internal combustion engine starts, the micro DC pump will return the lubricating oil stored in the double-layer vacuum insulation container to the oil ...

Abstract

The invention relates to a lubricating oil waste-heat recycling and reutilization method for an internal combustion engine. The lubricating oil in an oil pan in the engine is delivered to a double-layer vacuum heat-preserving vessel through a pipeline of a miniature straight-flow pump; when the internal combustion engine stops working after working for a period of time, the lubricating oil in the oil pan is introduced to the double-layer vacuum heat-preserving vessel through the miniature straight-flow pump, and since the lubricating oil in a water tank is in a high temperature state in the working process of the internal combustion engine, the waste heat generated in the working process of the internal combustion engine is stored in the double-layer vacuum heat-preserving vessel to achieve the purpose of recycling the waste heat of the lubricating oil of the internal combustion engine; and when the internal combustion engine is started, the lubricating oil stored in the double-layer vacuum heat-preserving vessel is output to the oil pan through the miniature straight-flow pump, and the temperature of the internal combustion engine rises through an oil suction disc and via an oil pump to achieve the purpose of reutilizing the waste heat of the lubricating oil of the internal combustion engine. The invention is simple and skilful in design, energy-saving and suitable for various diesel locomotives.

Description

Technical field [0001] The invention relates to a method for recycling waste heat, in particular to a method for recovering waste heat of lubricating oil generated during the operation of an internal combustion engine. Background technique [0002] In the prior art, it is difficult for motor vehicles such as various automobiles, tractors, and agricultural vehicles to start under low temperature conditions. Generally, when the temperature is in the range of -10°C to -15°C, it is difficult for the car to start cold. When the temperature drops below -40°C, it cannot be started at all without preheating. One of the reasons for the difficulty in starting the internal combustion engine at low temperature is that the temperature of the cylinder head, cylinder liner, and piston is low, which absorb a large amount of heat from the compressed gas in the combustion chamber, so that the temperature of the compressed gas cannot reach the combustion temperature when the compression ends;...
