摘 要：
It was designed based on the MC9S12XS128 MCU.The peak-hold type driving circuit of the NG gas jet valve and the single-cylinder independent ignition driving circuit were used according to the characteristics of LNG engine,and the NG temperature control scheme was designed in order to solve the impacts of the different NG temperatures which gasified from vaporization in different conditions.The results of Hardware-in-the-Loop test show that the electrical control system can achieve the control functions of in-turn engine ignition and single-point-continuous fuel injection.
