AI Technical Summary

Technical Problem

Existing gas generator sets have difficulty adjusting the air-fuel ratio under different environmental conditions, leading to problems such as abnormal combustion and flameout.

Method used

The system employs a multi-fuel generator set control system, which includes a fuel switching switch, an engine start switch, a carburetor, a gas supply electronic control valve, a signal detection module, and a control device. The signal detection module detects the engine's operating status signal and sends it to the control device, which controls the on/off state of the gas supply electronic control valve and the ignition timing of the ignition device. The air-fuel ratio is adjusted using an oxygen sensor.

Benefits of technology

It achieves closed-loop control of air-fuel ratio under different environmental conditions, improves engine starting performance and operational stability, and enhances the adaptability and operating efficiency of generator sets.

Abstract

The invention discloses a multi-fuel generator set control system, a multi-fuel generator set control method and a generator set, which are applied to the technical field of generator sets. The control system comprises a fuel change-over switch, an engine starting switch, a carburetor, a fuel gas supply electric control valve, a signal detection module, an ignition device and a control device. A gas fuel supply pipeline of the multi-fuel engine is connected with a gas inlet of the gas supply electric control valve, and a gas outlet of the gas supply electric control valve is connected with a gas fuel inlet of the carburetor. And the signal input end of the fuel type detection circuit is connected with the fuel change-over switch. And the signal output ends of the oxygen sensors are respectively connected with the signal input end of the control device. The oxygen sensor is used for detecting an oxygen content signal, and the oxygen content signal is used for adjusting the air-fuel ratio. Closed-loop control over the air-fuel ratio can be achieved through oxygen content signals collected by the oxygen sensor so as to adapt to different air oxygen contents caused by different environmental parameters.
