Problems solved by technology

When the motor vehicle is running cold, the lubricating oil has not yet heated up to the ideal working condition. At this time, the internal combustion engine often has poor lubrication effect and low working efficiency, especially the engine in the motor vehicle driving in the city. The distance is not far, and the low speed or idling operation takes a large proportion of the time, so the engine is usually in a cold car working condition, which has a great impact on the fuel consumption of the internal combustion engine

Embodiment Construction

[0015] Below in conjunction with embodiment the present invention is described in further detail:

[0016] The invention uses exhaust gas discharged from the engine to heat the lubricating oil of the engine, so that the lubricating oil of the engine reaches the set ideal lubricating working temperature as soon as possible and maintains the ideal lubricating working temperature. Such as figure 1 As shown, the steps of the method for reducing engine oil consumption by using exhaust waste heat in the embodiment of the present invention are as follows: After the engine exhaust gas and the engine lubricating oil drawn from the engine lubricating passage are introduced into the heat exchanger for heat exchange, low-temperature exhaust gas and high-temperature lubricating oil are obtained. , introduce high-temperature lubricating oil into the engine slideway as a lubricating medium for recycling, and discharge low-temperature exhaust gas at the same time; in the process of heat excha...

Abstract

The invention discloses a method for reducing emission and oil consumption of an engine by using tail gas waste heat, and relates to the technical field of engines. The method comprises the following step: heating engine lubricating oil by use of tail gas exhausted by the engine, so that the engine lubricating oil reaches a set ideal lubricating working temperature as quickly as possible, and is kept at the ideal lubricating working temperature. Compared with the prior art, the method is used for reducing the emission and the fuel oil consumption of the engine by utilizing the tail gas waste heat, so that the energy waste is reduced.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to a method for reducing engine emissions and fuel consumption by using exhaust waste heat. Background technique [0002] The internal combustion engine is an energy conversion mechanism that converts the heat energy generated by fuel combustion into mechanical energy. It mixes and atomizes air and fuel in proportion to form a combustible mixture and introduces it into the cylinder, then compresses the combustible mixture that enters the cylinder, ignites it, and generates high-pressure propulsion after combustion and expansion. The piston works, and finally discharges the exhaust gas after combustion. The fuel utilization rate of the engine is low, and about 35% of the heat energy is discharged with the exhaust gas. The exhaust gas is usually treated by the three-way catalytic converter and then discharged into the atmosphere through the muffler. When the motor...
