Abstract

This invention relates to an automatic system used in collecting and analyzing the combustion pressure data in the cylinder of a lower-middle speed engine connected by a pressure sensor, a Hall sensor, an upper dead point gear disk, a signal amplifier, a terminal board, a data collection card and a PC, in which, said system amplifies the pressure signal in the cylinder collected by the pressure sensor by a signal amplifier and cuts in it together with the signal of the upper dead point collected by the Hall sensor to the terminal board then collects the signals into the PC set by a high speed collecting card and the software of the data collection and combustion analyzing system mounted in the PC set displays the collected signal waveforms to compute curves of combustion heat discharge rate, heating volume and the temperature in the cylinder.

Description

technical field [0001] The invention relates to an automatic system for collecting combustion pressure data in a medium-low speed engine cylinder and utilizing the obtained cylinder pressure data for combustion analysis. Background technique [0002] The design, development and improvement of electronically controlled engines, new fuel engines and traditional engines are inseparable from the research and analysis of the combustion process of the engine, and the combustion pressure in the cylinder (indicator diagram) is an important performance parameter (curve) that characterizes the combustion process of the engine. ). Therefore, accurate collection of real-time in-cylinder pressure signals and effective and accurate combustion analysis are the basis and key to the study of engine combustion process. [0003] The existing research on the combustion pressure data acquisition and combustion analysis system in the engine cylinder is relatively mature, but most of them use ext...
