Problems solved by technology

[0003] At present, it is mainly based on the engine running time and vehicle mileage to decide whether to replace a new spark plug. However, due to the different driving habits of drivers and vehicle operating conditions, the aging degree of spark plugs is different. Simply based on engine running time and vehicle mileage , cannot accurately judge the aging degree of the spark plug, and thus cannot replace the spark plug in time

Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] The invention continuously adjusts the ignition energy of the spark plug under standard working conditions until the engine misfires, and compares the minimum ignition energy of the normal ignition of the spark plug with the standard value to determine the aging coefficient of the spark plug, which provides more accurate replacement and maintenance of the spark plug. basis. Describe in detail below the aging detection method of the spark plug provided b...

Abstract

The invention discloses a sparking plug aging degree detecting method and device, and a vehicle. Through an online test of an engine, the ignition energy of a sparking plug is continuously adjusted, the minimum ignition energy of normal ignition of the sparking plug is determined, the minimum ignition energy is compared with a standard value, the aging coefficient of the sparking plug is determined, accurate detection of the aging degree of the sparking plug is achieved, and more accurate basis is provided for replacement and maintenance of the sparking plug.

Description

technical field [0001] The invention relates to the technical field of engines, and more specifically, to a method, a device and a vehicle for detecting the aging degree of a spark plug. Background technique [0002] Gasoline engines generate power through the timely combustion of fuel and mixed gas, but gasoline as fuel is difficult to ignite spontaneously even in high temperature environments, and it is necessary to use "fire" to ignite it in order to make it combust at the right time. The spark plug is a device in the gasoline engine ignition system that introduces high-voltage current into the cylinder to generate electric sparks to ignite the combustible mixture. [0003] At present, it is mainly based on the engine running time and vehicle mileage to decide whether to replace a new spark plug. However, due to the different driving habits of drivers and vehicle operating conditions, the aging degree of spark plugs is different. Simply based on engine running time and ve...
