Example Embodiment

[0022] In order to further explain the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0023] See Figure 1 to Figure 7 As shown, the gas electronic injection valve for a gas fuel engine includes a housing 9, a solenoid valve component and a valve core component. The solenoid valve component and the valve core component are coaxially mounted on the housing, and the solenoid valve component is located above the valve core component. The shell 9 is made of hard aluminum alloy, and high-performance fluorine rubber is installed between the magnetic valve part and the shell 9, between the valve core part and the shell 9, and around the gas inlet and the gas outlet of the shell 9 Material O-ring 10. The solenoid valve component includes a solenoid valve housing 1 and an iron core coil 2. The iron core 21 of the iron core coil 2 is E-shaped and is formed by stacking FeSiCr sheet material...

Abstract

The invention discloses a fuel gas electronic injection valve used for a gas fuel engine. The fuel gas electronic injection valve comprises a shell, an electromagnetic valve component and a valve element component. The valve element component comprises a valve element, a valve block, a valve seat and an armature, wherein the valve block is installed in the valve element and fixedly connected with the lower end of the armature; when the electromagnetic valve component is powered on, under the effect of electromagnetic force, the armature pulls the valve block to upwards move so as to form a fuel gas channel between the lower surface of the valve block and the upper surface of the valve seat; and when the electromagnetic valve component is powered off, the lower surface of the valve block and the upper surface of the valve seat are attached to form a sealing face, and the fuel gas channel is blocked. The fuel gas electronic injection valve can be suitable for high-speed gas machines and dual-fuel engines, and the requirements of high response speed, accurate fuel gas metering, wide single cylinder power covering scope and the like are met.

Description

technical field [0001] The invention relates to a gas engine and a dual-fuel engine component, in particular to a gas electric injection valve for a gas fuel engine. Background technique [0002] The new emission regulations define extremely strict limits for the NOx, SOx and particulate matter content in the exhaust gas. With the market's strong pursuit of clean power, the engine industry is vigorously developing gas fuel engine technology. The gas engine ferry has been successfully operated in Norway, and the tugboat will follow. Dual-fuel and even tri-fuel engines have been used to power LNG vessels and offshore oil and gas platforms for many years. As one of the main fuels, gaseous fuel has its own characteristics: low temperature, no lubrication, extremely dry and corrosive. Considering the differences between gaseous fuels and traditional fuels, the design and manufacture of fuel supply systems will inevitably face many new challenges. [0003] As the core componen...
