Problems solved by technology

The application of the common rail pipe in the single-point injection control system is currently in the development stage in China, because the single-point injection system has very high requirements on the sealing of the gas, and at the same time requires the gas injected from the single-point injection system to flow smoothly in the common rail pipe , and the common rail pipe has to bear very high pressure. These factors lead to a great increase in the difficulty of the design and production of the common rail pipe

Abstract

The invention discloses a common-rail pipe of a gas engine. The common-rail pipe comprises a tubular gas main, wherein one end of the gas main is provided with a sensor mounting port for mounting a sensor, and the other end of the gas main is provided with a gas entrance; the gas main is provided with a plurality of gas manifolds which are arranged in a straight line; the gas manifolds are circular pipes vertically communicated with the gas main; one side of the gas main, which is opposite to the gas manifolds, is provided with more than two connecting pieces for fixing the common-rail pipe; and a mounting seat for assembling the common-rail pipe is arranged between the gas manifolds. According to the common-rail pipe of the gas engine, a plurality of manifolds are arranged on the gas main, so that the structure is simple and compact, the manufacturability is good, the reliability is good, and the gas flow is unobstructed.

Description

technical field [0001] The invention relates to the technical field of gas engines, and more specifically relates to a gas engine common rail pipe. Background technique [0002] For a long time, gas engines on the market generally use electronically controlled pressure regulation to control the amount of air and gas, so that the air-fuel combustible mixture enters the cylinder to organize combustion. At present, through the optimization and upgrading of the gas engine control system, an electronically controlled single-point injection system is introduced to more accurately control the amount of air and gas. Based on the working principle of the single-point injection system, combined with the different characteristics of different engine charge requirements, there must be a set of devices To ensure the durable and reliable gas input and output of the single-point injection system, this device is a common rail pipe. The application of the common rail pipe in the single-poin...
