Description

Intake pipe for gas engine

technical field

The utility model relates to an intake pipe, in particular to an intake pipe for a gas engine.

Background technique

Existing gas engines are generally four cylinders or six cylinders, the mixture of gas and air enters each cylinder of the gas engine through the intake pipe, and the current intake pipe distributes the intake air volume of the mixture of gas and air entering each cylinder Inhomogeneity, and thus inconsistent combustion between individual cylinders, affects the efficiency of the gas engine.

Contents of the invention

The technical problem to be solved by the utility model is to provide an intake pipe for a gas engine, which can make the mixture of gas and air entering each cylinder of the gas engine uniform, thereby improving the efficiency of the gas engine.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is: the air intake pipe for a gas engine includes a pipe body, the axial middle part of the pipe body is provided with a general air intake port, and the pipe body is provided with a pipe for respectively communicating with each other. Several single-cylinder intake manifold interfaces of each cylinder of the gas engine, the single-cylinder intake manifold interfaces are evenly distributed in the axial direction.

As a preferred solution, the total intake port and the interface of the single-cylinder intake manifold are arranged radially opposite to each other.

As a preferred solution, the number of the single-cylinder intake manifold interfaces is six.

As a preferred solution, the pipe body is provided with several fixing seats along the axial direction, and the fixing seats are arranged radially opposite to the interface of the single-cylinder intake manifold.

As a preferred solution, the tube body is provided with a sensor mount for fixing the temperature and pressure sensor.

After adopting the above-mentioned technical scheme, the effect of the utility model is: because the air intake pipe for the gas engine includes a pipe body, the axial middle part of the pipe body is provided with a general air inlet, and the pipe body is provided with a Respectively corresponding to several single-cylinder intake manifold interfaces connected to each cylinder of the gas engine, the single-cylinder intake manifold interfaces are evenly distributed in the axial direction, therefore, connect each single-cylinder intake manifold interface to the corresponding gas engine The cylinders of the cylinders are connected, and the mixture of gas and air enters the pipe body from the main intake port. Since the main intake port is set in the middle of the axial direction, and the single-cylinder intake manifold interface is evenly distributed in the axial direction, the gas and air The mixed gas enters into each cylinder of the gas engine very evenly, thereby improving the efficiency of the gas engine.

Detailed ways

A kind of air intake pipe for gas engine, as shown in Figure 1, Figure 2 and Figure 3, it comprises pipe body 1, and the axial middle part of described pipe body 1 is provided with general air inlet 2, and described pipe body 1 is provided with There are a number of single-cylinder intake manifold interfaces 3 corresponding to each cylinder of the gas engine, and the single-cylinder intake manifold interfaces 3 are evenly distributed in the axial direction.

The total intake port 2 and the single-cylinder intake manifold interface 3 are arranged radially opposite to each other. In this embodiment, the number of the single-cylinder intake manifold interfaces 3 is six. Certainly, if the number of cylinders of the gas engine is four, the number of the single-cylinder intake manifold interfaces 3 is also four. The pipe body 1 is provided with several fixing seats 4 along the axial direction, and the fixing seats 4 are arranged radially opposite to the single-cylinder intake manifold interface 3, and the fixing seats 4 are used to connect the inlet The trachea is fixedly mounted on a bracket or other fixtures. The tube body 1 is provided with a sensor mount 5 for fixing the temperature and pressure sensor.

The working principle of the utility model is: connect each single-cylinder intake manifold interface 3 downwards with the cylinder of the corresponding gas engine respectively, and the mixed gas of gas and air enters the pipe body 1 from the total air inlet 2, Since the main intake port is arranged in the middle of the axial direction, and the single-cylinder intake manifold interface 3 is evenly distributed in the axial direction, the mixed gas of gas and air enters into each cylinder of the gas engine very uniformly, thereby improving the performance of the gas engine. efficiency.
