Embodiment Construction

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within 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. The method for detecting the aging degree of the spark...

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 present invention relates to the technical field of engines, and more particularly, to a method, device and vehicle for detecting the aging degree of spark plugs. Background technique [0002] A gasoline engine generates power through the timely combustion of fuel and mixed gas, but gasoline as a fuel is difficult to spontaneously ignite even in a high temperature environment. To make it combust in a timely manner, it is necessary to use "fire" to ignite. A spark plug is a device in the ignition system of a gasoline engine that introduces a high-voltage current into the cylinder to generate an electric spark 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 the new spark plug. However, due to the different driving habits of drivers and the different operating conditions of the vehicle, the spark plugs have different aging degrees. , the aging degre...
