Problems solved by technology

[0007] The technical route of multi-point injection of the existing branch pipe intake gas is injected into the intake manifold. Since there is still a certain distance between the manifold and the air passage in the cylinder head, when the engine load changes rapidly, the transient response speed of the engine will be reduced. Second, due to the gas residue in the intake manifold, the residual gas will enter the next cylinder with the air during the valve overlap period, which causes uneven work of each cylinder; finally, the residual gas in the intake manifold still exists Risk of tracheal flashback explosion

Embodiment Construction

[0024] The specific embodiments of the present invention will be described in detail below in conjunction with the drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0025] The specific implementation of the present invention is as follows: Figure 1-2 As shown, a fuel gas injection device includes a common rail tube body 1 with a hollow inside. One side of the common rail tube body 1 is protrudingly provided with a plurality of ports that can respectively connect each intake port on the cylinder head and the intake manifold. The transition pipe sockets 2 connected to the respective outlets of the gas outlets, and each transition pipe socket 2 is provided with a protruding jet pipe 3 that connects the inner cavity of the common rail pipe body 1 with the cylinder head intake port, and a gas injection system Installed between the intake manifold and the cylinder head. One end of the transition pipe ...

Abstract

The invention discloses a fuel gas jetting device. The device comprises a shared-rail pipe body of which the interior is hollow, one side of the shared-rail pipe body is provided with multiple transition pipe bases making all air inlets in an air cylinder cover and all air outlets in an intake manifold communicated respectively in a protrusion mode, each transition pipe base is provided with a gas ejector pipe which is protruded outside and communicate the inner cavity of the shared-rail pipe body with an air inlet channel of the air cylinder cover, an accommodating cavity which extends in the lengthwise direction of the pipe body and can be sealed is formed in the other side of the shared-rail pipe body in an inward-sunken mode, exhaust ends communicated with the inner cavity of the shared-rail pipe body and multiple jetting metering valves making the gas ejector pipes and the inner cavity of the shared-rail pipe body communicated respectively, and a double-layer venting structure and an anti-leaking fuel gas structure are arranged on the shared-rail pipe body. The fuel gas jetting device can effectively prevent fuel gas from leaking into an engine room, which makes fuel gas combustion safe and reliable.

Description

Technical field [0001] The invention relates to the field of internal combustion engines, and more specifically, it relates to a gas injection device. Background technique [0002] With the gradual implementation of my country's energy structure adjustment and energy saving and emission reduction strategies, natural gas engines have begun to be used more and more on inland vessels. However, due to the lag in the construction of infrastructure such as inland gas stations and related technical specifications and management specifications are not perfect, it is difficult to promote a single fuel gas engine within a period of time. As a transitional power, dual-fuel gas engines play a positive role in the exploration and development of the application of natural gas in the water operation industry. The dual-fuel can be completed by adding gas supply devices, gas injection devices, and gas control parts to existing fuel-powered ships. The transformation of ships, with low transformat...
