Problems solved by technology

If oil and gas remain in the cylinder for too long, it will seriously corrode the cylinder and shorten the life of the cylinder
In addition, the oil and gas remaining in the cylinder for a long time will also cause carbon deposits on the spark plug and the cylinder head, making it difficult to restart the engine, thereby increasing the power consumption of the battery 100

Abstract

The invention provides a method for controlling an idling mode of an engine, which is suitable for the engine in the idling stop mode. The engine comprises a cylinder head, a cylinder, a piston and a crank. The ignition control method comprises the following steps: firstly, detecting the crank angle to judge the position of the piston; secondly, beginning to perform a delay ignition action when the crank is rotated positively to a first ignition angel behind an upper dead center to ensure that the positive rotation inertia force of the crank is weakened after the delayed first ignition angle each time; thirdly, opening a vent valve of the cylinder head when the positive rotation inertia force of the crank cannot overcome the upper dead center and the crank is rotated inversely; and fourthly, performing an ignition action when the crank is rotated reversely to a second ignition angle. Therefore, residual oil gas can be combusted again to meet the requirement of environmental protection.

Description

【Technical field】 [0001] The present invention relates to an ignition control method of an engine, in particular to an ignition control method of an engine in an idle stop state. 【Background technique】 [0002] Nowadays, the problems of global warming, air pollution and energy shortage have gradually attracted people's attention. In order to improve the above problems, in the prior art, a device that can automatically turn off the engine in idle speed has been proposed as follows: Motor vehicle engine idle speed control device". [0003] figure 1 It is a structural diagram of an existing motor vehicle engine idle speed control device. see figure 1 , the idle speed control device shown in it is used to automatically turn off the engine when the motorcycle is idle, so as to reduce the consumption of gasoline and reduce the emission of exhaust gas. [0004] figure 1 The disclosed "engine idling control device for motor vehicle" is composed of a battery 100, a main switch 1...
