基于HIP9011的二冲程煤油发动机爆震识别系统研究
Research on Knock Identification System of Two Stroke Kerosene Engine Based on HIP9011
摘要
Abstract
In order to solve the knock intensity limit the use of safety,power and economic issues in heavy two-stroke engine,this research designed two-stroke kerosene engine knock recognition system based HIP9011.It can identify shock state of the two-stroke kerosene engine explosion rapidly and accurately,and established a good foundation for the two-stroke kerosene engine knock control.This paper used intrinsic modal feature energy method to extract the detonation characteristic frequency of the body vibration signal and determined the detection range of the knock signal according to the cylinder pressure curve.Two-stroke kerosene engine knock detection system is designed based on Infineon cx2765x chip and the HIP9011 chip,and it designed PC system to display the operating state of the engine by using LabVIEW.A two-stroke kerosene engine test bench was set up and tested.The experimental results show that the knock detection system can accurately judge the engine knock status and knock intensity.关键词
