Problems solved by technology

Since the operating conditions of each vehicle are different, and the driver's operating habits are also very different, the accuracy of judging the aging degree of the spark plug by this method is low, resulting in the aging of the spark plug, but due to the uneven running time and mileage The preset value is not reached, so the spark plug is not replaced in time, which affects the normal performance of the engine

Embodiment 1

[0047] This embodiment provides a spark plug aging monitoring method, which can monitor the spark plug aging in the engine at any time with high accuracy.

[0048] Such as figure 1 Shown, this spark plug aging monitoring method comprises the steps:

[0049] S1. Determine that the engine of the vehicle is in a preset detection working condition.

[0050]Wherein, this step is the preparatory work before monitoring. The preset detection working conditions may be working conditions such as no failure of the engine, and engine cylinders not being ignited. By setting the engine in a preset detection working condition, the influence of other factors (such as the running condition of the engine) on the monitoring result can be reduced, and the accuracy of the monitoring result can be improved. Optionally, the ending procedure in this embodiment means that the spark plug to be tested is not monitored. When the engine is not in the preset testing condition, if the spark plug to be t...

Embodiment 2

[0093] This embodiment also provides a spark plug aging monitoring system, which can implement the spark plug aging monitoring method in the above embodiment, such as image 3 As shown, the spark plug aging monitoring system includes:

[0094] A determining module 401, configured to determine that the engine of the vehicle is in a preset detection condition.

[0095] The opening module 402 is used for opening the Lamda closed-loop control, so as to provide air to the target cylinder where the spark plug to be tested is located in the engine.

[0096] The control module 403 is used to ignite the target cylinder through the spark plug to be tested, and is used to record the actual charging time of the ignition coil connected to the spark plug to be tested when the instantaneous speed change value of the engine when the target cylinder is ignited is greater than the preset speed change value.

[0097] The first determination module 404 is used to determine the aging coefficient ...

Embodiment 3

[0108] The embodiment of the present invention also provides a storage medium on which a computer program is stored, and when the program is executed, the spark plug aging monitoring method as described in the above-mentioned embodiments of the present invention is realized.

[0109] Certainly, a storage medium containing computer-executable instructions provided by the embodiments of the present invention, the computer-executable instructions are not limited to the operations in the spark plug aging monitoring method as described above, and the spark plug provided by the embodiments of the present invention can also be executed. Relevant operations in the aging monitoring method, and have corresponding functions and beneficial effects.

[0110] Through the above description about the implementation mode, those skilled in the art can clearly understand that the present invention can be realized by means of software and necessary general-purpose hardware, and of course it can al...

Abstract

The invention discloses a spark plug aging monitoring method and system and a storage medium, and belongs to the technical field of vehicle engine monitoring. The spark plug aging monitoring method comprises the steps that when an engine is in a preset detection working condition, Lamda closed-loop control is started firstly, and a target cylinder is ignited; and then the actual charging durationof an ignition coil connected with a spark plug to be tested is recorded when an instantaneous rotating speed change value of the engine is greater than a preset rotating speed change value when the target cylinder is ignited, the aging coefficient of the spark plug to be tested is obtained according to the actual charging duration, and if the aging coefficient of the spark plug to be tested is greater than the preset aging coefficient, when the current running mileage of a vehicle is smaller than the preset mileage, it is determined that a monitoring result of the spark plug to be detected isin an aging state. By means of the spark plug aging monitoring method, the spark plug can be detected online in real time, the aged spark plug can be replaced in time, and normal work of the engine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle engine monitoring, in particular to a spark plug aging monitoring method, system and storage medium. Background technique [0002] The engine is used to provide power to the vehicle to drive the vehicle to move. Natural gas engines generate power by burning a mixture of natural gas and air. Moreover, the natural gas engine needs to use the spark plug to ignite the mixture in the gas cylinder. The spark plug provides ignition energy through the high-voltage coil, thereby forming a high-energy spark between the center electrode and the ground electrode, and then igniting the mixture in the cylinder. The aging degree of the spark plug directly affects the combustion state of the engine. [0003] In the prior art, the most common way to monitor the aging status of spark plugs is to judge whether the spark plugs are aging based on the engine running time and vehicle mileage during vehicle maintenanc...
