Abstract

The application discloses an on-line monitoring system for an automobile engine, comprising: a data acquisition module, a data processing module, an exhaust fluctuation signal database, a pattern recognition module, an analog-to-digital converter, a control module, a circular linked list, a memory module and a diagnosis module. This application is interconnected with other automotive electronic control systems such as the engine centralized controller through bus technology, and becomes a unit of the automotive internal network; this system can not only be used as a powerful tool for engine optimization control, but also can be used for other types of vehicles through software transplantation. Engines and different applications; the system interface type can be set according to requirements, thus making the system more versatile, and has long-term application prospects in internal combustion engine fault diagnosis, optimal control and noise control of automotive engines.

Description

technical field [0001] The application belongs to the field of automobile monitoring, and in particular relates to an on-line monitoring system of an automobile engine. Background technique [0002] The automobile engine is a very complex mechanical, electrical and hydraulic system, which consists of two major mechanisms (crank linkage mechanism, gas distribution mechanism) and five major systems (fuel supply system, cooling system, lubrication system, ignition system, and starting system). There are also many types of faults, and the relationship between the fault phenomenon and the cause is also complicated, which may be one-to-many, many-to-one or many-to-many. Different faults manifest in different ways. Therefore, what kind of detection object to choose, which parameters to detect, and how to carry out signal analysis and data processing are the main problems to be solved in condition monitoring and fault diagnosis. [0003] The traditional engine performance detection...
