Abstract

The invention belongs to the technical field of engines, and in particular relates to a dual-fuel engine pressure regulating device and a dual-fuel engine with the same. The dual-fuel engine pressure regulating device of the present invention comprises a valve body, a slider, a first inlet, a second inlet and a first outlet, the slider is slidably arranged inside the valve body, and The interior of the valve body is divided into a first chamber and a second chamber, the first inlet is used to communicate with the first chamber and the external pipeline of the valve body, and the second inlet is used to communicate The second chamber and the external pipeline of the valve body, the interior of the slider is provided with a conduction channel, and the first outlet can be connected to the interior of the first chamber through the conduction channel Pass. According to the dual-fuel engine pressure regulating device of the present invention, the pressure balance between the first chamber and the second chamber can be ensured, thereby ensuring the pressure balance of different fuels during the injection process.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a dual-fuel engine pressure regulating device and a dual-fuel engine with the same. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] In an existing dual-fuel engine, when fuel injection is performed, it is necessary to ensure a certain pressure balance relationship between the two fuels. However, the pressure control technology of some fuels is not very mature, and it is difficult to control the pressure of the fuel at a certain value. Therefore, it is difficult to ensure the pressure balance between different fuels during the dual fuel injection process, resulting in insufficient combustion of the fuel in the engine. , What is more harmful to the engine. Contents of the invention [0004] It is an object of the invention to at least solve the problem of pre...
