Device for heating vehicle engine oil by utilizing tail gas

Abstract

The invention relates to a device for heating vehicle engine oil by utilizing tail gas, in particular to a device for heating the low-temperature engine oil of an engine by utilizing the tail gas of a vehicle, which comprises an exhaust pipe, wherein a bypass branch pipe is arranged on the exhaust pipe, a sealing door is installed at the shunting openings of the exhaust pipe and the bypass branch pipe, one end of the sealing door is connected with a switch shaft, the switch shaft is connected with a cylinder through a pulling arm outside the exhaust pipe, and a heat-insulating layer and a heating oil jacket are sequentially coated outside the bypass branch pipe. The device adopting the scheme has simple and compact structure and uses the tail gas to rapidly heat the vehicle engine oil, thus the heating time of the engine oil in the low-temperature state of the vehicle can be shortened, the oil consumption can be reduced, and the pollutant discharge can be reduced. The device can be widely applied to the design of the auxiliary systems of various vehicles, particularly vehicles used in severe cold areas after being slightly modified so that good technological approaches for the energy saving and the emission reduction of the vehicle is provided.

Description

technical field [0001] The invention relates to an auxiliary equipment on a vehicle, in particular to a device for heating the low-temperature engine oil of the engine by using the exhaust gas of the vehicle itself. Background technique [0002] With the vigorous development of the automobile industry, automobiles have gradually become a daily necessity and have entered the lives of ordinary people. However, with the popularization of automobiles, the environmental pollution caused by automobile exhaust has become the top priority of energy saving and emission reduction in countries all over the world. All countries in the world are committed to research and development of energy-saving products to reduce fuel consumption and carbon dioxide emissions. [0003] When the car is started, the engine oil temperature is low, and the frictional resistance of the internal parts of the engine is relatively high, which not only affects the service life of the engine, but also fuel co...
