一、系统概述 1983年大连海运学院科研所研制成功了检测柴油机燃烧和喷油过程的微型计算机系统,并已应用在远洋货轮育英号、丁湖山号和机车厂柴油机试验台上。对监视柴油机气缸内的工作是否正常起了很大作用,对研制和改进柴油机也有重大的意义。 这一系统在柴油机气缸盖的示功阀上装一个压电石英式或应变仪式压力传感器,用来检测气缸内气体的压力。如条件允许,还可以在喷油器前的高压油管上装一个专门的三通接头,接头上装一个测量油压的压电石英或应变仪式传感器。把喷油器略加改造,可以装一个喷油器针阀升程传感器。在柴油机的飞轮附近,
I. System Overview In 1983, Dalian Institute of Marine Science and Research successfully developed a miniature computer system for testing the combustion and fuel injection of diesel engines and has been applied to the offshore freighters Yuying, Dinghushan and locomotive diesel engine test stands. The monitoring of diesel engine cylinder work is normal play a significant role in the development and improvement of diesel is also of great significance. The system is equipped with a piezoelectric quartz or strain gauge pressure sensor on the pilot valve on the cylinder head of a diesel engine to detect the pressure of the gas in the cylinder. If conditions permit, you can also install a special three-way connector on the front of the high-pressure fuel pipe of the injector. The connector is equipped with a piezoelectric quartz or strain gauge sensor that measures the hydraulic pressure. The injector slightly modified, you can install a injector needle lift sensor. Near the flywheel of a diesel engine,
