Problems solved by technology

However, the current multi-point EFI generally has one injection valve for each cylinder, that is to say, several injection valves are needed for several cylinders. The above structure has the following problems: 1. High failure rate; There is a difference in jet flow between the valves, and its energy consumption is high; 3. The cost is high

Abstract

The invention discloses an automobile fuel gas injection valve. One end of an air outlet of a valve body is provided with an output gas distribution device, and the output gas distribution device comprises a shell, a gas distribution chamber arranged in the shell and at least one discharging channel communicated with the gas distribution chamber and located below the gas distribution chamber. Thevalve body is internally provided with a switching device for opening and closing the air outlet. The output gas distribution device further comprises a regulating device for regulating the output flow rate of the air outlet, the regulating device comprises a screwed plug, a nut and a screw rod, and one end of the screw rod passes through the screwed plug and is matched with the nut by a screw thread. In the invention, after entering through an air inlet, gas enters into the gas distribution chamber through the air outlet, and then the gas is supplied to a gas cylinder through a plurality of discharging channels from the gas distribution chamber, thus the vehicular fuel gas injection valve realizes the purpose of simultaneously injecting gas to a plurality of gas cylinders by one injectionvalve, and the injection process can not generate flow rate difference and has low energy consumption.

Description

(1) Technical field [0001] The invention relates to an automobile gas injection valve, which is provided with an output gas distribution device and can simultaneously output gas to a plurality of cylinders through one injection valve. (2) Background technology [0002] With the rise of gasoline prices and in order to protect the ecological environment, buses or cars on the market began to use natural gas as vehicle fuel to replace gasoline and diesel. At present, vehicle gas devices include single-point self-priming and electronic injection. The single-point self-priming type is to install the mixer in front of the throttle valve, which can only improve the degree of gas mixing at the throttle valve, but it is difficult to solve the problem of backfiring and blasting in a section of the pipe wall from the throttle valve to the intake manifold. Therefore, the structure of the intake manifold has a major impact on the delivery and distribution of the mixture, and it is difficu...
