摘要
隨著全世界范圍內(nèi)汽車技術(shù),尤其是汽車電子控制技術(shù)的迅猛發(fā)展,我國汽車工業(yè)進步很快,進口汽車增幅很大,以電控發(fā)動機為代表的電控裝備的維修已經(jīng)成為汽車檢測與維修行業(yè)的重點和難點。本文先介紹了電控發(fā)動機的發(fā)展歷史而后著重介紹了汽油機的電控燃油噴射系統(tǒng)的組成、工作原理及檢修,最后介紹了柴油機電控燃油噴射系統(tǒng)、共軌技術(shù)的發(fā)展及原理。為了使和汽車專業(yè)有關(guān)人員能更全面、系統(tǒng)的掌握和理解有關(guān)汽車發(fā)動機電控燃油噴射系統(tǒng)的結(jié)構(gòu)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 service.But after this article first introduced the electrically controlled engine development history to introduce emphatically the gasoline engine electrically controlled fuel injection system composition, the principle of work and the overhaul, finally introduced the diesel engine electrically controlled fuel injection system, altogether the axle technology development and the principle.In order to enable with the automobile specialized concerned personnel more comprehensive, 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
