Abstract

The invention discloses an electromagnetic fuel injection valve, which comprises a spray pipe inlet. An iron core is arranged in the spray pipe inlet, and a coil is wound on the iron core; the coil is connected with an electrode plate; a spring is arranged in the iron core; one end of the spring is pressed in the iron core, while the other end is pressed on a magnet; a spray pipe main body is sleeved outside the magnet; the spray pipe main body is in sealed connection with the spray pipe inlet; a valve seat is arranged in the spray pipe main body and is provided with a valve hole; and the front end of the magnet is fixed with a steel ball which is matched with the valve hole and is used for closing and opening the valve hole. The injection valve has the advantages of accurate control of oil injection, quick dynamic response, high product stability, simple structure and low processing cost.

Description

technical field [0001] The invention relates to an electromagnetic injection valve, in particular to an injection valve used in an electronically controlled gasoline engine fuel injection system. Background technique [0002] The electronic gasoline injection valve is the core component of the electronically controlled gasoline injection system of the automobile engine, which has an important influence on the combustion and emission performance of the automobile. Electronic gasoline injection valves precisely meter fuel and create a fuel spray. Due to the high requirements for the injection accuracy of oil mist, and the harsh environment such as high temperature, high pressure and vibration in the engine, the requirements for the accuracy and stability of the injection valve are very high, so the processing accuracy and production cost of the product are raised. requirements. The currently used electronic gasoline injection valve has complex structure, high processing cost...
