Ignition system and ignition control method of motorcycle

Abstract

The invention provides an ignition system of a motorcycle. The ignition system of the motorcycle comprises an accelerator cable, a magnet, a magnetic switch, a rotating speed sensor, and a digital igniter, wherein the accelerator cable synchronously rotates along with a carburetor; the magnet synchronously rotates along with the accelerator cable; the magnetic switch is closed and a closing signal is closed when the accelerograph opening is smaller than critical accelerograph opening, and the magnetic switch is cut off when the accelerograph opening is not smaller than the critical accelerograph opening; the rotating speed sensor is used for detecting the rotating speed of an engine and transmitting a rotating speed signal; the digital igniter is used for calculating the rotating speed acceleration, controlling an advance angle of ignition according to an economy cruise curve if the closing signal is received, and controlling the advance angle of ignition according to a power cruise curve if the closing signal is not received when the rotating speed acceleration is smaller than the preset acceleration; the digital igniter is used for controlling the advance angle of ignition according to an economy acceleration curve if the closing signal is received, and controlling the advance angle of ignition according to a power acceleration curve if the closing signal is not received when the rotating speed acceleration is not smaller than the preset acceleration. The dynamic performance and the economic performance of the motorcycle are improved by the ignition system. The invention also provides an ignition control method of the motorcycle.

Description

technical field [0001] The invention relates to the technical field of motorcycle ignition, and more specifically, relates to an ignition system and an ignition control method of a motorcycle. Background technique [0002] At present, most motorcycle ignition systems use capacitor discharge igniters, which only have an ignition curve of an analog signal. The ignition curve is a relationship curve between the engine speed and the ignition advance angle. Taking the ignition advance angle as the ordinate, the curve is roughly: when the engine speed is not greater than 1500r / min, the ignition angle advance angle is 15°; when the engine speed is higher than 1500r / min but lower than 3000r / min, the ignition angle advance angle is is 15~30°; when the engine speed is higher than 3000r / min, the ignition angle advance angle is 30°. Define the low speed range when the engine speed is not greater than 3000r / min, the medium speed range when the speed is between 3000r / min and 6000r / min, a...

Problems solved by technology

[0003] Since there is only one analog signal in the igniter, the ignition curve is the relationship curve between the engine speed and the ignition advance angle set when the engine load is a constant value, which leads to the ignition advance angle of the engine at high load and high speed. Larger, smaller output power, resulting in larger fuel consumption, making the motorcycle's power performance and economic performance poor
