Multi-spot electrojet device for gas generator

Abstract

The invention relates to a multi-spot electrojet device for a gas generator, which comprises a cylinder body, a crank, an air intake manifold, an ignition device, an electric controller and a gas passage, wherein the ignition device is connected with the electric controller, a jet nozzle communicated with each pipeline of the air intake manifold is arranged on the gas passage, and the signal end of the jet nozzle is connected with the electric controller. The multi-spot electrojet device is characterized in that a rotating speed sensor used for detecting the rotating speed of the generator is connected onto the electric controller, a crank angle sensor connected with the electric controller is arranged on the crank, and the ignition device and the jet nozzle are connected with the electric controller through a speed regulator. Because of the adoption of the technical scheme, the multi-spot electrojet device has the advantages that the use is convenient, the structure is compact, the engine can maintain the stable rotating speed of 3000r or 1500r and the like, the multi-spot electrojet is adopted, the air-fuel ratio can be effectively controlled, the mixing is more sufficient, the combustion is more complete, the output power of a generator set is improved, the exhaust of harmful gas is reduced, and the response is faster.

Description

technical field [0001] The invention relates to a gas generator set, in particular to a gas electric injection device. Background technique [0002] At present, most of the engines that use gas as fuel are modified from gasoline engines. At the place where the gas intake is mixed, the main method is to directly connect the gas pipeline in front of the throttle, and absorb the fuel to do work through the negative pressure of natural suction. Or adopt the off-the-shelf Venturi type mixer, the air flow can increase the negative pressure to absorb fuel when passing through the mixer. Both of the above use a naturally aspirated hybrid to fuel the engine. However, the fuel system of this structure has the same problems as the carburetor-type engine, such as the air-fuel ratio cannot be controlled, the mixing is insufficient, the combustion is incomplete, and the emission is not up to standard. At present, the electronic control method is generally used to regulate the speed of ...

However, the fuel system of this structure has the same problems as the carburetor engine, such as the air-fuel ratio cannot be controlled, the mixing is insufficient, the combustion is incomplete, and the emission is not up to standard

At present, the electronic control method is generally used to regulate the speed of the generator. The negative pressure of the engine is used to inhale, and the mixture is mixed through the carburetor or the Venturi tube, and then the intake of the mixed gas is controlled by the throttle connected to the electronic speed regulating motor. In order to achieve the purpose of speed regulation, it has a limited effect on the stability of the unit, and will directly affect the response speed of the generator set for loading and unloading. The unit power supply gas consumption rate is high, the power is low, the mixing is insufficient, and harmful gas emissions More, causing environmental pollution, unable to keep the engine at a stable speed such as 3000 or 1500
