Embodiment Construction

[0012] Referring to accompanying drawing 1, what the embodiment of the present invention shows is the capacitive discharge type electronic igniter used on the outboard motor, including generating coil, charging and discharging circuit, ignition angle control circuit, ignition coil, wherein, the generating coil L1 of the magneto , which is the AC voltage generated by cutting the lines of force when the magnetic field of the magneto rotates. It is not only the power supply of the whole igniter but also the trigger signal source.

[0013] When the alternating voltage in L1 is up positive and down negative, the rectification and charging circuit composed of diode D1, capacitor C1 and ignition coil T1 completes a charging process to capacitor C1. When the voltage in L1 is lower positive and upper negative, it is rectified by diode D5, filtered by inductor L2 and current-limited by resistor R1, and the trigger pulse is added to the control electrode of the thyristor SCR. At this tim...

Abstract

The invention relates to a capacitor discharge type electronic igniter for an engine. The capacitor discharge type electronic igniter comprises a generator coil, a charge / discharge circuit, an ignition angle control circuit and an ignition coil. As an L2, an RT and an R2 are added, trigger current has smaller fluctuation and no back angle; as the L2 and the RT are added, the error trigger rate is smaller and the igniter is more reliable; as a D3 is added, residual voltage on a primary coil is totally released to protect the primary coil, and the power is increased; and as a trigger coil is not needed, the cost is reduced, and the reliability is enhanced.

Description

technical field [0001] The invention relates to a capacitive discharge electronic igniter for an engine and belongs to the field of electronic technology. Background technique [0002] In the prior art, a capacitor discharge type electronic igniter for an engine is composed of a generating coil, a charging and discharging circuit, an ignition angle control circuit, and an ignition coil. When the magneto rotates, positive and negative alternating currents are induced in the charging electrical winding of the magneto. When the charging winding of the magneto is positive and negative, the current passes through the semiconductor diode to charge the energy storage capacitor, and the electric energy required by the ignition coil is stored in the capacitor. When the rotation of the magneto rotor becomes negative up and down positive, the ignition angle control circuit triggers the thyristor to conduct, and the current stored in the capacitor quickly discharges to the primary of t...
