Embodiment Construction

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

[0023] see Figure 1 to Figure 7 As shown, the gas electric injection valve for a gas fuel engine includes a housing 9, a solenoid valve part and a valve core part, the solenoid valve part and the valve core part are coaxially installed on the housing, and the solenoid valve part is located above the valve core part. The casing 9 is made of hard aluminum alloy, and high-performance fluororubber is installed between the magnetic valve part and the casing 9, between the valve core part and the casing 9, and around the gas inlet and gas outlet of the casing 9. Material O-ring seal 10. The solenoid valve components include a solenoid valve casing 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 materials.

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...
