Abstract

The invention relates to an ignition device for a gasoline engine, in particular to a piezoelectric ignition system of a single-cylinder gasoline engine under a fixed working condition. The piezoelectric ignition system of the single-cylinder gasoline engine under the fixed working condition comprises a camshaft, and an air inlet cam and an exhaust cam are arranged on the camshaft. A piezoelectriccam is further arranged on the camshaft, and a fixed seat plate is arranged below the piezoelectric cam. A piezoelectric device is fixed above the seat plate, and the piezoelectric device is connected with a sparking plug in the gasoline engine through a guide wire. A normally open switch is mounted on the guide wire. The camshaft can rotate, and drive the piezoelectric cam to periodically extrude the piezoelectric device downwards, then current is generated, the current is released through the sparking plug, atomized gasoline in the gasoline engine can be periodically ignited, and then the gasoline engine runs. The piezoelectric device is provided with piezoelectric ceramics.

Description

technical field [0001] The invention relates to a piezoelectric ignition system for a single-cylinder gasoline engine with a fixed working condition, which relates to an ignition device for a gasoline engine. Background technique [0002] The ignition system of a traditional gasoline engine has a series of electrical equipment and electrical appliances such as a battery. Its structure is relatively complex and occupies a large volume. , chainsaw engine, the crankshaft speed of the engine remains almost constant, the ignition timing and ignition advance angle are basically unchanged, but the requirements for the working environment and portability are high, so an ignition system with a simple structure and light weight is required to adapt such a request. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned deficiencies and provide a single-cylinder gasoline engine piezoelectric ignition system with a fixed working condi...
