柴油機(jī)電子控技術(shù)柴油機(jī)電控技術(shù)源于上世紀(jì)八十年代，首先應(yīng)用的是燃油噴射系統(tǒng)的電子控制。目前先進(jìn)的燃油噴射系統(tǒng)如共軌燃油噴射系統(tǒng)已在轎車和重型卡車柴油機(jī)上得到批量應(yīng)用。如Wart Si la、MAN Bamp。除了電控燃油系統(tǒng)外，其它系統(tǒng)也開始改用電控方式，MAN Bamp。MAN Bamp。柴油機(jī)電子管理技術(shù)可對(duì)柴油機(jī)性能實(shí)現(xiàn)更高層次的控制，主要完成柴油機(jī)監(jiān)測(cè)、控制和故障診斷和與外延設(shè)備的聯(lián)系等功能，柴油
