Methanol intake manifold device, engine and automobile

Abstract

The invention discloses a methanol intake manifold device, an engine and an automobile. The methanol intake manifold device comprises an intake manifold, a fuel injector, a piezoelectric ceramic wafer and a high-frequency signal generator, wherein the fuel injector is used for ejecting a methanol fuel spray into the intake manifold, the piezoelectric ceramic wafer is arranged in the intake manifold and disposed in the fuel spray direction of the fuel injector or the downstream area of the fuel spray direction, and the piezoelectric ceramic wafer is electrically connected with the high-frequency signal generator and used for converting a high-frequency signal sent by the high-frequency signal generator into high-frequency mechanical vibration so as to scatter the liquid methanol molecular structure. According to the technical scheme, through the piezoelectric ceramic wafer and the high-frequency signal generator, the problem that methanol atomization is difficult is solved, cold start of the automobile can be realized by using methanol fuel, it is unnecessary to use two sets of fuel supply systems, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a methanol intake manifold device, an engine and an automobile. Background technique [0002] In recent years, methanol, as a fuel to replace raw coal and oil and gas, has gradually been used in automobiles, ships, industrial boilers, heating and other fields, resulting in better economic and environmental benefits. On March 19, 2019, the Ministry of Industry and Information Technology, the National Development and Reform Commission and other departments jointly issued the "Guiding Opinions on the Application of Methanol Vehicles in Some Areas", which requires strengthening the rational layout of the methanol vehicle industry and maintaining the quality of products, technologies and special-purpose products of methanol vehicles and related industries in my country. The international leading position in the field of equipment will accelerate the construction of methanol automobile ...

AI Technical Summary

Problems solved by technology

Under this scheme, methanol vehicles need to use two sets of fuel supply systems, including two sets of fuel tanks, fuel pipelines, fuel rails, and fuel injectors, which not only increase the cost of the vehicle, but also cause difficulties in the layout of the fuel supply system, and OBD (On Board Diagnostics , on-board automatic diagnostic system) problems with increased difficulty in diagnosis
