Abstract

The invention discloses a device with a changeable gas injection direction and a changeable orifice number, and aims to solve the problems that the gas injection direction and the orifice number cannot be changed in the prior art. The device with the changeable gas injection direction and orifice number is composed of a nozzle (1) and a sealing bolt subassembly. The nozzle (1) is a cylinder type structural member formed by a circular cylinder and a spherical end face; gas orifices are formed in the spherical end face. The sealing bolt subassembly is composed of a No. 1-1 sealing bolt (3), a No. 1-2 sealing bolt (4), a No. 1-3 sealing bolt (2), ellipsis, a No.1-M sealing bolt, a No. 2-1 sealing bolt, a No. 2-2 sealing bolt, ellipsis, a No.2-M sealing bolt, ellipsis, a No. N-1 sealing bolt, a No. N-2 sealing bolt, a No. N-3 sealing bolt, ellipsis, and a No. N-M sealing bolt, wherein the screws of all the sealing bolts are provided with external threads; the sealing bolt subassembly is arranged in the gas orifices on the nozzle (1) in a threaded connection manner.

Description

technical field [0001] The invention relates to a gas injection device used in a gas fuel engine, more specifically, the invention relates to a gas injection direction and injection hole number variable device. Background technique [0002] Gas fueled engines greatly reduce NO while reducing petroleum fuel consumption X It has made great contributions to improving the environmental pollution caused by vehicle exhaust and alleviating the dependence of countries around the world on petroleum fuels. The flow in the cylinder and the concentration distribution of gas in the cylinder have a great influence on the combustion of gaseous fuel. The gas intake method commonly used in gas fuel engines is multi-point injection in the intake port. The latest research results show that when the fuel enters the cylinder in the way of multi-point injection in the intake port, just like direct injection in the cylinder, the gas and air are not mixed uniformly. Different injection direction...
