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...
