Embodiment Construction

[0019] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, in this embodiment, the gasoline engine igniter circuit includes a single-chip microcomputer chip power supply circuit, a signal trigger circuit, a capacitor discharge ignition circuit and an igniter flameout function circuit, and the single-chip microcomputer chip power supply circuit provides the necessary working voltage for the single-chip microcomputer chip to work. The signal trigger circuit uses another inductor and its back-end circuit to realize the generation of the trigger signal, which does not interfere with the power supply circuit. Then, when the single-chip microcomputer chip is working normally, after receiving the trigger signal, the single-chip microcomputer chip outputs the trigger level. Make the igniter work and ignite.

Abstract

The invention relates to a gasoline engine igniter controlled by a single-chip microprocessor (SCM). The gasoline engine igniter comprises a capacity discharge ignition circuit, a signal trigger circuit, an SCM chip power supply circuit and an SCM chip integrated circuit (IC) 1, wherein, the capacity discharge ignition circuit, the signal trigger circuit and the SCM chip power supply circuit are controlled by an SCM chip; and as the signal trigger circuit and the SCM chip power supply circuit are mutually independent without interfering with each other, the SCM chip power supply circuit does not adsorb the current in the trigger coil of the signal trigger circuit, thus increasing ignition energy, improving the stability of the whole circuit, ensuring sufficient combustion of thegasoline in an engine, and reducing environmental pollution.

Description

technical field [0001] The invention relates to an automobile igniter, in particular to a gasoline engine igniter controlled by a single-chip microcomputer. Background technique [0002] The current gasoline engine igniter technology is mostly controlled by a single-chip microcomputer. The power supply voltage of the single-chip microcomputer in this type of igniter is taken from the trigger coil circuit. The power supply circuit of the single-chip microcomputer chip will absorb most of the current in the trigger coil circuit of the igniter, causing the igniter The ignition current is low and unstable, resulting in the overall low ignition energy and rapid attenuation of high-speed ignition energy, resulting in problems such as incomplete combustion of gasoline, substandard exhaust emissions, and poor high-speed stability of the engine. [0003] The open date is June 7, 2000, and the public number is CN2381806Y, a high-voltage high-frequency igniter controlled by a single-ch...
