Abstract

The invention discloses a starting exhaust device for an engine fuel control system. The device comprises a machine body, a first cavity and a second cavity are formed in the machine body, the second cavity is located below the first cavity, the top face of the first cavity is communicated with an extrusion cavity, and the top face, located in the center, of the extrusion cavity is communicated with an air inlet pipe; and two exhaust hole grooves are formed in the annular inner wall of the air inlet pipe in a communicating manner, and exhaust mechanisms are arranged in the two exhaust hole grooves in a communicating manner. According to the device, a cylindrical protrusion is matched with a cylindrical clamping groove to provide buffer for a cylindrical piston during pushing, and two movable blocks on a limiting rod are matched with a buffer spring to provide buffer for the cylindrical piston during resetting, so that the cylindrical piston is effectively protected, and the service life of the cylindrical piston is prolonged; and an annular joint on an exhaust pipe is sleeved with an annular block provided with a dustproof net, and the annular block is in threaded connection with the annular joint, so that the dustproof net can effectively provide dustproof protection for the exhaust pipe, and impurities are prevented from entering the exhaust pipe.

Description

technical field [0001] The invention relates to the technical field of engine fuel control systems, in particular to a starting exhaust device for an engine fuel control system. Background technique [0002] The engine fuel control system is mainly composed of a fuel storage tank, a fuel pump, a fuel filter, a fuel supply rail, and a fuel injector. The function of the fuel control system is to supply the gasoline required for combustion into the cylinder. Mixed combustible gases are formed in the housing cavity of the cylinder, so it is necessary to evacuate the mixed combustible gases in the cylinder housing cavity. [0003] When the existing starting exhaust device for engine is actually used, the internal exhaust piston lacks a limit protection structure, and the exhaust pipe port lacks a dustproof structure. Now a starting exhaust device for engine fuel control system is proposed to solve the problem. above question. Contents of the invention [0004] The present inv...
