Abstract

The invention discloses an automatic calibration method for engine knock. The automatic calibration method for engine knock comprises the steps of carrying out knock control matching by adopting engine knock intelligent-calibration, self-adaption and self-studying technologies; collecting the following equipment running data: temperature, rotate speed, oil consumption condition and ignition anglecondition; storing the data, and carrying out secondary analysis; and intelligently optimizing knock calibration. By adopting the technical scheme, the complex control logics such as cylinder detection, data analysis and processing are greatly simplified; and along with the development of a knock sensor technology and an electronic technology, the accuracy in signal acquisition is realized, and irrelevant noise can be eliminated through filter analysis in different ways and detonation sensor feedback signal processing in different ways, so that the engine work knock situation can be accuratelydiscriminated, control parameters such as advance angle of ignition are dynamically adjusted, the accuracy control requirement of a high-speed internal combustion engine is met, and the whole intelligent calibration process is realized.

Description

technical field [0001] The invention belongs to the technical field of automobile engine testing. More specifically, the present invention relates to an automatic calibration method for engine knock. Background technique [0002] Engine Management System (Engine Management System, namely EMS): In 1979, BOSCH integrated the ignition advance angle electronic control and fuel quantitative electronic control, developed Motronic, and introduced knock control, exhaust gas recirculation, etc. to meet more To meet the stricter performance and emission requirements, its electronic control range covers the entire engine, which is called the engine electronic management system, and its core is the electronic control of fuel quantification and ignition timing. Its technical solution is: [0003] 1. Through the matching of the engine stand, the engine has good steady-state performance, and the design power, torque and fuel consumption performance of the engine can be achieved under the...
