| 摘 要： | 由于石油资源逐渐枯竭和严格限制汽车排放污染，促使世界各国广泛发展车用天然气发动机。该课题研究通过自行建立的柴油天然气双燃料供应系统，采用发动机台架试验方法，分析了车用柴油天然气双燃料发动机的工作特性和双燃料的控制方法，提出一种电子控制方案，并进行了可行性试验，初步试验结果令人满意。但与国外同类技术相比，其控制功能仍需进一步完善。

| Abstract: | Natural gas engines for vehicles have widely been developed in the world because of lacking oil resources and stern exhaust regulations for vehicles.In this paper a fuel delivery system with diesel and natural gas is set up.According to the results of engine bench,the paper describes the operation performance of diesel/natural gas dual fuel engines for vehicles and analyzes controlling methods for dual fuels.The test of the electronically controlled dual fuel engine has been conducted and the results showed that the control method for diesel fuel was easy to meet the requirement of engine output torque.The control method is an advanced one in the inland but control functions should be improved further. |
