Embodiment 1

[0035] This application relates to a natural gas supply device for engines, which provides natural gas supply for dual-fuel engines. The main structure of the gas supply device is a double-wall support pipe 1, a natural gas injection valve 2, a double-wall corrugated pipe 3, and a double-wall gas supply pipe 4. There is a cylinder head that needs to be used on the engine, and several natural gas intake passages and pressurization passages are arranged on the cylinder head, so that each double-walled support pipe 1 corresponds to a natural gas intake passage, and the double-walled support pipe 1 1 is fixedly connected to the cylinder head, so that the natural gas delivery cavity in the double-walled support tube 1 communicates with the natural gas intake channel on the cylinder head, and the upper end of the double-walled support tube 1 is fixedly installed with the natural gas injection valve 2, and the natural gas injection valve 2 The upper end of the double-wall corrugated p...

Abstract

The invention belongs to the technical field of engine natural gas system fixing, and particularly relates to a natural gas system fixing frame based on an engine cylinder cover. The natural gas system fixing frame comprises a double-wall supporting pipe, the double-wall supporting pipe is fixedly connected with a natural gas inlet channel of the cylinder cover, and a natural gas injection valve is arranged at the upper end of the double-wall supporting pipe; a double-wall corrugated pipe is arranged at the upper end of the natural gas injection valve, a double-wall air supply pipe is arranged at the upper end of the double-wall corrugated pipe, the double-wall supporting pipe comprises an air cavity between the double walls, the double-wall corrugated pipe comprises an air cavity between the double walls, and the double-wall air supply pipe comprises an air cavity between the double walls; and the cylinder cover is further provided with a pressurized air inlet channel, the pressurized air inlet channel is connected with the natural gas inlet channel in an acute angle manner, air can enter an air inlet cavity, when natural gas leaks, the air inlet cavity can suck the natural gas in the air cavity from an air inlet connector, and then the concentration of the leaked natural gas is reduced.
