Ignition control method for motorcycle engine

Abstract

The method relates to an electronically controlled system of a motorcycle, in particular to an ignition control method of the electronically controlled system of the motorcycle. The method comprises the following steps: S1, storing calibration data in a memory of ECU; S2, acquiring position signals and status data of a piston by the ECU, after the operation of a motor, calculating data for a basic ignition angle by ECU according to the operating position of the piston; S3, comparing the calibration data of step S1 with the status data of step S2 by the ECU, and obtaining the revised data for the basic ignition angle; S4, overlapping the data of the basic ignition angle calculated in the step S1 and the revised data for the basic ignition angle calculated in step S3 by the ECU to obtain data of a preignition angle; and S5, transmitting the obtained data of the preignition angle calculated in step S4 to an ignition coil by the ECU and controlling the ignition of the ignition coil by the ECU. The method well controls the ignition process, allows an engine to ignite at the best moment and causes the mixed air in the cylinder to fully burn, therby reaching effects of diminishing the oil consumption and improving the quality of tail gas.

Description

technical field [0001] The method relates to the technical field of electric control systems of motorcycles. In particular, the invention relates to an ignition control method of an electronic control system of a motorcycle. Background technique [0002] The air pollution caused by motorcycle exhaust emissions has become an increasingly urgent research topic, especially for small and medium-sized cities, motorcycles have become an indispensable means of transportation for people. How to control the pollution caused by motorcycle exhaust to the atmosphere has become an urgent problem to be solved. It is well known that to reduce the pollution caused by motorcycle exhaust emissions, there are many solutions, such as purifying the inside of the engine and treating the exhaust system outside the engine. Practice has proved that the most effective motorcycle exhaust treatment solution is to use an electronic control unit to control the EFI process of the motorcycle engine. The...

Problems solved by technology

However, most of the existing motorcycles that have been used are not equipped with electronic control units. Although some motorcycles are equipped with electronic control units, because the internal control program of the electronic control unit is not reasonable enough, the effect of the motorcycle on exhaust gas control Not ideal, so it is necessary to improve the electronic control unit in the existing motorcycle
