Injector and vehicle

Abstract

The invention provides an injector and a vehicle so as to solve the problem that in the prior art, methanol fuel cannot be fully injected into a combustion chamber. The injector comprises a base, a nozzle, a first injection pipe and a second injection pipe, wherein the base is provided with a first mounting hole and a second mounting hole; the nozzle is connected with the base and communicated with the first mounting hole and the second mounting hole; the first injection pipe is arranged in the first mounting hole, an outlet of the first injection pipe is communicated with the nozzle, and the first injection pipe is used for conveying methanol to the nozzle; and the second injection pipe is arranged in the second mounting hole, an outlet of the second injection pipe is communicated with the nozzle, and the second injection pipe is used for conveying gasoline to the nozzle. According to the injector, two kinds of fuel injectors are combined into a whole, the first injection pipe and the second injection pipe are connected to the combustion chamber through the base and the nozzle, two kinds of fuel can be injected at the same position, the methanol injection distance is the same as the gasoline injection distance during injection, the methanol injection distance is shortened, and the methanol can be fully injected into the combustion chamber.

Description

technical field [0001] The invention relates to the field of mechanical structures, in particular to an injector and a vehicle. Background technique [0002] At present, the market is vigorously promoting methanol vehicles. The methanol engine needs to run normally, and methanol must be injected into the combustion chamber before it can be burned. As a new type of liquid fuel, methanol has a high ignition point and a large latent heat of vaporization. It needs to absorb a large amount of heat at the beginning of combustion. If the vehicle is cold and injects methanol directly into the combustion chamber, the engine will fail to ignite. [0003] In order to solve the problem that methanol cannot be ignited in a cold car, the vehicle is first ignited with gasoline, and when the temperature of the vehicle rises, methanol is injected into the combustion chamber, and methanol has been continuously used since then. [0004] Current vehicles use two sets of fuel injection systems...
