Problems solved by technology

[0003] Compared with the inductive discharge ignition system, the CDI ignition system has the advantage of fast ignition, but the biggest disadvantage of this system is that the spark duration is very short (about a few hundred nanoseconds), and the electric energy provided by the motorcycle power supply to the ignition system Restricted, the mixed gas cannot be fully burned, which restricts the performance of the engine and correspondingly increases the emission of pollutants

Abstract

This invention relates to motorcycle direct current portfire with high efficiency, which belongs to motorcycle portfire technique and adds one magnetic machine coil on the base of motorcycle original capacity portfire system. The portfire coil second adopts floating earth method and realizes the aim by multiplying the coil through high reverse diode and connecting the piston electrode.

Description

Technical field [0001] The invention belongs to the field of fuel motorcycle ignition devices. Background technique [0002] Contemporary motorcycles all use capacitor discharge ignition system, which is called CDI ignition system. The following introduces the working principle of the CDI ignition system. figure 1 A conventional motorcycle ignition device is shown, wherein the ignition device includes a magneto 1, a CDI ignition system 5, an ignition coil 6, a spark plug 7, and a magneto winding L 2 , Diode VD 4 , SCR V S , trigger switch IK, capacitor C 3 , ignition coil 6 and spark plug 7 constitute a standard capacitive discharge ignition system, at this time, L 2 The output voltage via VD 4 to C 3 Charge. Under the triggering action of the trigger switch IK, the one-way thyristor V S conduction, C 3 Energy through the ignition coil primary N 1 release, the ignition coil secondary N 2 An ignition high voltage is generated in the middle, the spark plug is broke...
