The design of the main research engine and electronically controlled fuel injection system to control the actuator principles, electric control system sensor applications, diesel engine electronic control system, electric control unit (ECU) design and electronic control technology in the future development trend, in which electronic control unit mainly controlled by microputer. Electrical control system to replace mechanical control is not only to improve the control of diesel engine operating parameters measurement precision also satisfy the energy conservation requirements. Improve the diesel engine, intelligent electronic control system is an important future research direction of the world39。 關(guān)鍵詞： 傳感器 。電氣化控制系統(tǒng)取代機(jī)械化控制不僅提高柴油機(jī)運(yùn)行參數(shù)測量的控制精度也滿足了節(jié)能減排的要求。 I 摘 要 為了降低柴油機(jī)的能源消耗，滿足節(jié)能和排放法規(guī)的要求，電子控制技術(shù)在柴油機(jī)中的應(yīng)用和發(fā)展已經(jīng)成為必不可少的一個(gè)壞節(jié)。本設(shè)計(jì)主要研究柴油機(jī)電控噴油系統(tǒng)和執(zhí)行器的控制原理、電控系統(tǒng)中傳感器的應(yīng)用、 柴油機(jī)電控系統(tǒng)的電控單元 （ ECU） 設(shè)計(jì)及電控技術(shù)未來的發(fā)展趨勢 ，其中電子控制單元主要由單片機(jī)控制。 提高柴油機(jī)電控系統(tǒng)的智能化是未來世界重工業(yè)研究的重要方向，是 各國綜合實(shí)力的象征。 ECU。s heavy industry, is a symbol of national prehensive strength.
