Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] combine figure 1 As shown, an automatic calibration system for steady-state engine conditions includes an engine and an AVL standard bench for providing the engine with the conditions required for engine operation. The AVL is automatic vehicle positioning, and the AVL standard bench provides the engine with a The various conditions required can stabilize the load of the engine at the same time. The AVL standard bench is provided with a sensor for detecting the running state of the engine. The engine is connected to the sensor. It includes a parameter configuratio...

Abstract

The invention provides an automatic engine stable state calibration system. A parameter configuration module transmits configuration parameters to a monitoring and variable-locking module, the monitoring and variable-locking module calculates to lock parameters according to the configuration parameters, and transmits the parameters to a management module, the management module controls the operating state of an engine according to the locked parameters, a sensor acquires and feeds the operating parameters of the engine back to the monitoring and variable-locking module, the monitoring and variable-locking module judges the operating parameters and transmits the operating parameters meeting requirement to the parameter configuration module, and the parameter configuration module receives and processes the operating parameters meeting requirement and generates and outputs calibrated parameters; in addition, an automatic calibration method utilizes a personal computer (PC) to calculate the parameters of the engine, automatically try to configure the parameters of the engine, acquire the parameter information in the operation of the engine in real time and record the calibrated parameters reaching the stable operation point, an operator only needs to carry out simple configuration, and thereby a great deal of time and a lot of material resources are saved.

Description

technical field [0001] The invention relates to an automatic calibration system and an automatic calibration method for an engine steady-state working condition. Background technique [0002] With the continuous development of the engine, the requirements for the calibration of various parameters of the engine are constantly increasing. The parameters that need to be calibrated for the engine are very large, and the relationship between them is very complicated. The traditional method of manually changing the parameter data for calibration , the professional technical level of the calibration personnel is high. In the calibration process of a parameter, a large number of calculations and repeated attempts are required, which consume a lot of working time and more material resources. Contents of the invention [0003] An object of the present invention is to overcome the frequent manual operation and time-wasting deficiencies of the engine steady-state calibration system in...
