Example Embodiment

[0014] Hereinafter, the present invention will be described in more detail with examples in conjunction with the accompanying drawings:

[0015] A gas engine multi-mode discharge ignition system includes: an ignition controller, a power supply, a capacitor energy storage type ignition coil, an inductive energy storage type ignition coil, an anti-reverse breakdown diode, an ignition high-voltage line interface and a spark plug. The system includes an inductive energy storage type ignition coil and a capacitor energy storage type ignition coil. The two ignition coils can be independently controlled and can switch the discharge mode according to the working conditions of the natural gas engine. There is a signal conditioning circuit inside the ignition controller, which regulates the top dead center signal and the speed signal into a standard square wave signal, and obtains the ignition control signal through the standard square wave signal, and the ignition control signal controls t...

Abstract

The invention relates to the technical field of gas engines, in particular to a multi-mode discharging ignition system which meets the requirement of natural gas engines for stable running under various conditions. The multi-mode discharging ignition system comprises an ignition controller, a power source, a capacitive energy-storage ignition coil, a first reverse-breakdown preventive diode, a high-voltage wire connector, a second reverse-breakdown preventive diode, an inductive energy-storage ignition coil and an ignition plug. The engine provides a top dead center signal and a rotation speed signal to the ignition controller in real time, the top dead center signal and the rotation speed signal are processed by the ignition controller to generate an ignition signal pulse which can control discharge time of the capacitive energy-storage ignition coil and the inductive energy-storage ignition coil. The ignition system is flexible to control and high in energy utilization rate, and the natural gas engine can stably operate under various conditions.

Description

technical field [0001] The invention relates to the technical field of gas engines, in particular to a multi-mode discharge ignition system for a gas engine that satisfies the stable operation of various working conditions of the natural gas engine. Background technique [0002] With the development of the economy, the energy crisis and environmental pollution are becoming increasingly serious, and people are paying more and more attention to the utilization of new energy sources such as natural gas. However, compared with traditional engine fuel gasoline and diesel, natural gas has a higher ignition temperature and slower flame propagation speed. When technologies such as lean burn and EGR are used to improve combustion efficiency and reduce NO X When it is easy to aggravate the variation of the combustion cycle, this puts forward higher requirements for the ignition system, requiring the ignition system to have higher ignition energy and longer ignition duration. Traditio...
