Embodiment Construction

[0013] A gas engine gas positive pressure injection mixing device is characterized in that it is an integral connection structure of a gas inlet part 1, a hexagonal mounting screw part 2 and an intake pipe insertion part 3.

[0014] The air intake pipe insertion part 3 is divided into three rows of small air injection holes 4 in tandem according to a division angle of 90° within 180° of the circumference.

[0015] The number of the air injection small holes 4 is 35, and the sum of the cross-sectional areas of all the small holes is twice the diameter of the gas inlet part (1).

[0016] The angle of the inclined plane of the insertion part 3 of the air inlet pipe is 45°

[0017] It is provided with a gas inlet part 1, a hexagonal mounting screw part 2, an inlet pipe insertion part 3, a low-pressure gas outlet and an air injection hole 4, such as figure 2 , during the actual engineering installation, different gas engine gas positive pressure injection and mixing devices can b...

Abstract

The present invention discloses a positive-pressure fuel gas injection and mixing unit of a gas engine. The unit is composed of a fuel gas inlet part (1), a hexagonal screw-down part (2) and an air inlet pipe insertion part (3) which are integrally connected together. The air inlet pipe insertion part (3) is circumferentially partitioned into multiple rows of longitudinally arranged air injectionpores (4). The sum of the sectional areas of all of the ten to fifty air injection pores (4) is two times larger than the drift diameter area of the fuel gas inlet part (1). The angle of the inclinedplane of the inserted part of the air inlet pipe insertion part (3) is 15 degrees to 60 degrees. The unit has the advantages of simple structure, small volume, convenient operation and adjustment, reliable operation performance, wide application range, safe use, simple assembly and easy maintenance.

Description

technical field [0001] The invention relates to a gas engine gas positive pressure injection mixing device. Background technique [0002] At present, the gas positive pressure injection mixing method of gas vehicles in my country mainly adopts Venturi mixer and proportional mixer, and the gas enters the intake manifold through the mixer for mixing. The processing technology of the mixer is difficult, there are many parts, and the cost is high, and it is often limited by the size of the engine intake pipe during the installation process. It has caused certain difficulties for the gasification transformation of in-use vehicles. Contents of the invention [0003] The object of the invention is: a gas engine gas positive pressure injection mixing device. [0004] The purpose of the present invention is achieved like this: [0005] A gas engine gas positive pressure injection and mixing device is characterized in that it is an integral connection structure of the gas inlet p...
