关键词:电子控制技术电控燃油喷射系统结构工作原理
Abstract
Along with the world scope in the automobile technology, the automobile electronic control technology swift and violent development, our country automobile industry progress is in particular very quick, imports the automobile increased range to be very big, already became the automobile examination and the service profession key point and the difficulty take the electrically controlled engine as representative's electrically controlled equipment after this article first introduced the electrically controlled engine development history to introduce emphatically the gasoline engine electrically controlled fuel injection position, the principle of work and the overhaul, finally introduced the diesel engine electrically controlled fuel injection system, altogether the axle technology development and the order to enable with the automobile specialized concerned personnel prehensive, system grasping with the understanding related motor car engine electrically controlled fuel injection system structure principle of work.
Keywords: Electronic control technology, electrically controlled fuel injection system, structure, principle of work
