Abstract

An electronic fuel injection device with self-adjusting valve for pulse exhaust engine and its fabricating method are provided. The device comprises combustion chamber, injection pipe, main fuel injector, cold start injector, blade electricity generator and self-adjusting inlet valve control system. Open and close of the inlet valve is controlled by the self-adjusting inlet valve control system according to the working frequency of the engine.

Description

technical field [0001] The invention relates to a pulse jet engine device and a control method of an electric jet with self-adaptive valves. technical background [0002] The pulse jet engine is divided into valve type and valveless type. The valve type means that there is a check valve at the air inlet at the front of the combustion chamber to prevent the detonation gas from being sprayed out in reverse from the intake pipe. The valveless type does not have this Function. Their working principles are basically the same: when combustible gas explodes and burns in the combustion chamber, that is, deflagration, high-temperature gas is generated and rapidly expands, and the expanded gas is ejected at high speed through the jet tube. produce forward thrust. [0003] For the valveless pulse jet engine, although its structure is simple, because the intake pipe of the combustion chamber inlet has no valve, part of the detonation gas will be ejected from the intake pipe in the opp...
