Abstract

An embodiment of the invention provides a three-way valve and an engine and relates to the technical field of vehicle equipment. The three-way valve comprises a three-way valve body and a pressure adjusting device, wherein the three-way valve body comprises a valve seat and a valve cover which are connected mutually, and a first through hole penetrating through the valve cover is formed in the valve cover; the pressure adjusting device comprises an elastic sheet, a first spring, a retaining nut and an adjusting bolt; the elastic sheet is clamped between the valve seat and the valve cover; theretaining nut is arranged in the first through hole and arranged on the adjusting bolt in a sleeving manner; one end of the first spring is connected with the elastic sheet, and the other end of the first spring is connected with the adjusting bolt. According to the three-way valve and the engine in the embodiment, oil pressure can be stabilized, so that the fuel metering accuracy of a flue spraynozzle is improved.

Description

technical field [0001] The invention relates to the technical field of automobile equipment, in particular to a three-way valve and an engine. Background technique [0002] The methanol engine uses M100 methanol as fuel, which has the advantages of good emission and good economy. However, due to the large latent heat of vaporization and poor evaporation of methanol at low temperature, it is difficult for the concentration of combustible mixture to reach the ignition limit, which makes it difficult for methanol engines to start cold at low temperatures. Gasoline, as a traditional fuel, has good evaporative properties. It can solve the problem of difficult cold start by injecting gasoline into the engine for combustion, and then injecting methanol after the engine water temperature reaches a certain temperature. At the same time, as a traditional fuel, gasoline is easy to refuel. The gasoline fuel supply system has mature technology and strong engineering implementation, whic...
