直接数字式电控柴油喷射是在电脑的智能化管理下,通过开关型高速电磁阀对由凸轮驱动的柱塞泵所产生的高压脉冲燃油进行直接调节,以实现对柴油机定时、油量、喷油率、喷射压力优化控制的一种高新技术。其具体系统形式主要包括电控泵喷嘴和本文作者在此基础上经结构变型和性能改进而研制的电控泵—管—嘴系统两种。前者目前是发达国家卡车柴油机的主要电控装置,而后者在国际上发表后,引起了良好反响。本文将以此为核心来介绍柴油机电控喷射技术的开发成果和运用实践,并对其在我国的发展提出建议。
Direct digital electronic diesel injection is the intelligent management of the computer through the switch-type high-speed solenoid valve driven by the cam-driven high-pressure pulsed pulse fuel pump directly to achieve the timing of diesel, fuel, spray Oil rate, injection pressure optimization control of a high-tech. The specific system forms mainly include the electric pump nozzle and the author of this article, based on the structural changes and performance improvements and developed two kinds of electric control pump - pipe - nozzle system. The former is currently the main electronic control device for truck diesel engines in developed countries, and the latter has caused good repercussions since its publication in the world. This article will take this as the core to introduce the development and application of diesel electronic injection technology, and put forward some suggestions on its development in our country.
