Digital direct-current igniter for motorcycle

Abstract

The invention relates to an igniter for a motor vehicle, in particular to a digital direct-current igniter for a motorcycle. The digital direct-current igniter comprises a trigger pulse shaping circuit, a negative pulse separation circuit, a positive pulse separation circuit, an ignition advance angle control circuit, a boosting circuit taking a boosting transformer and a switch power tube as cores, and an ignition discharging circuit, and is characterized in that: the ignition advance angle control circuit takes a singlechip processor as a core; and the singlechip processor controls the boosting circuit in a pulse width modulation (PWM) mode. The ignition advance angle control circuit takes a singlechip as a control core, and the ignition advance angle of an engine is subjected to accurate curve control through the quick operation and control functions of the singlechip, so that the engine works in an optimal state; and the PWM control mode is adopted, so that constant high power is output when the boosting transformer is started, and the rise rate of charging voltage of an ignition capacitor is improved.

Description

technical field [0001] The invention relates to a motor vehicle igniter, in particular to a motorcycle digital direct current igniter. Background technique [0002] The principle and function of the motorcycle igniter is to receive and store the ignition energy provided by the magneto or power supply, and determine the ignition advance angle according to the ignition trigger signal. At the appropriate ignition moment, the ignition energy pulse is released instantaneously and provided to the primary of the ignition coil. A high voltage is induced in the secondary of the ignition coil, which causes the spark plug to generate a discharge spark. There are various ignition methods for motorcycles, and there are three commonly used ones: inductive discharge battery ignition method, capacitor discharge battery ignition method, and capacitor discharge magneto ignition method. The three ignition methods have different structures and cannot be interchanged when used. The inductive d...
