摘　　要：分析TBD234V6型柴油机改装为天然气/柴油双燃料发动机的技术原理,对关键部件及控制策略进行了设计和研究。台架试验表明,改装后的双燃料发动机与原机相比,动力性保持不变,排放有部分改善;在负荷突加突卸的情况下,具有较好的响应特性;燃油替代率较高;系统具有良好的操作性、安全性和可靠性;经济效益和社会效益较好。The techniques of modifying TBD234V6 diesel engine into natural gas/diesel oil dual fuel en- gine are introduced, the key components and controlling strategy were developed and researched. The test bed research show that the dynamic performance of modified dual fuel engine remains unchanged com- pared with the prototype ; the emission is partially improved ; in the conditions of sudden load and unload, it shows good response; the ~uel replacement ratio is high; the operative performance is good; the safety and reliability are satisfactory; it achieves good economic and social benefits.
