Motorcycle engine control method and device thereof

Abstract

The invention discloses a method and a device for controlling a motorcycle engine. The device is used for judging an operating state of a motorcycle, controlling automatic flameout of the engine and re-starting the engine so as to reduce oil consumption in a process of stopping and operating the motorcycle at an idle speed. The invention checks operation information of the motorcycle through an ignition control chip module to judge a current operation state of the motorcycle. When the ignition control chip module checks that the motorcycle is in a static state, the engine operates at the idlespeed, and a position of throttle opening of the motorcycle is a default value of an origin point, after the conditions are satisfied, the position of the throttle opening is a default value of the time of the automatic flameout, the ignition control chip module controls the automatic flameout of the engine. When the ignition control chip module checks that the throttle opening of the motorcycle is changed to be more than a default value of the voltage of the throttle opening, the ignition control chip module controls a relay to act and starts up a motor to operate, and controls a spark plug to ignite and re-start the engine.

Description

technical field [0001] The invention relates to a motorcycle engine control method and its device, in particular to a method and its device for judging the running state of the motorcycle, controlling the engine to automatically shut down, and restarting the engine. Background technique [0002] In today's society, motorcycles are people's favorite short-distance means of transportation because of their sensitivity and speed. However, in recent years, energy shortage issues and environmental protection awareness have risen. How to make vehicles save energy and reduce pollution has become the goal of vehicle development. [0003] As shown in Figure 1, it is the structure diagram of the "motor vehicle engine idle speed control device" disclosed by the Chinese patent publication number CN1815012A. degree, restart the engine. [0004] Among them, the "motor vehicle engine idle speed control device" disclosed by the Chinese patent case publication number CN1815012A is to close ...

AI Technical Summary

Problems solved by technology

However, when the car is going downhill or driving, the throttle will also be reset to zero, which may easily lead to a misjudgment that the car is idling for a stop, and the engine will stop running, causing danger on the road.

And its control engine stops running, needs to make instruction through electronic control unit 108, control engine trigger coil 110 short circuit or open circuit, easily cause time and cost to increase

In addition, it does not take into account that the battery 100 needs to be started repeatedly when it is idle, which will easily cause the power to drop and cause the engine to fail to start, which will easily cause inconvenience and danger.
