Abstract

The invention discloses a multi-point injection gas engine and a gas mixer, comprising a gas outlet casing extending into an air intake passage, the head end of the gas outlet casing is connected to a gas supply mechanism, and the gas outlet casing is provided with a penetrating The first air outlet hole and the second air outlet hole inside and outside the air outlet housing, and the extension lines of the centerlines of the first air outlet hole and the second air outlet hole intersect in the air inlet channel. In the present invention, the gas is regulated by the gas mixer and sprayed into the intake port of the cylinder head. Through the unique intersection and collision, an umbrella-shaped radiation surface is formed, and the mixing area of ​​the gas and the air in the intake port of the cylinder head is increased, so that the gas and air are Uniform mixing in the intake passage; at the same time, the gas mixer is an independent structure and is not integrated with the cylinder head. Compared with the prior art, the manufacturing difficulty and cost are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of gas engines, in particular to a multi-point injection gas engine and a gas mixer. Background technique [0002] The technical scheme of the gas engine adopting the gas multi-point injection technology is to install a gas injection valve at the air intake passage of the cylinder head of each engine. After the gas injection valve injects the gas into the intake passage, the gas and air Mixed, their mixture along the intake port, through the intake valve of the cylinder head into the combustion chamber. Whether the gas and air are mixed uniformly in the intake port is an important technical point of whether the gas can be fully burned in the combustion chamber. The more uniform the two are mixed, the more uniform the mixture can be formed in the combustion chamber, which will burn after being ignited. The more fully, the higher the combustion efficiency. [0003] In order to improve the combustion efficien...
