As the enhancement of independence innovation awareness and the automobile electronic industrialization was brought forward , a new wave of automobile motor electronic control unit ( ecu ) research has shown up . consequently , some electronic fuel injection ( efi ) motor systems which can meet the standard of eu - i and eu - ii have been worked out 隨著自主創(chuàng)新意識的增強,汽車電子產(chǎn)業(yè)化口號的提出,國內(nèi)掀起了汽車發(fā)動機電子控制單元( ecu ? electroniccontrolunit )研究的熱潮,相繼設計出排放達到歐i 、歐ii標準的電噴發(fā)動機系統(tǒng),但在實際應用中,還存在著種種的問題。
