点火延迟时间测量系统的研制
A SYSTEM FOR MEASURING IGNITION DELAY TIME
-
摘要: 自行研制的催化点火器点火延迟时间测量系统使用微机技术、实时在线测量,测试精度高、系统稳定可靠,并完成了多批次国产催化点火器的鉴定工作。稍加改装,还可用于各类点火系统的点火延迟时间测量。Abstract: A measuring system for ignition delay time,which consists of an Intel 8253 chip,a microcomputer,an electric magnetic valve and an ultraviolet photodiode was developed.It can realize the real-time and on-line measurement with precision of 0.001 second.The system has been used successfully in measuring of ignition delay time to appraise the performance of a catalytic igniter.
