| Abstract:The techniques of modifying TBD234V6 diesel engine into natural gas/diesel oil dual fuel engine 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 compared with the prototype; the emission is partially improved; in the conditions of sudden load and unload, it shows good response; the fuel replacement ratio is high; the operative performance is good; the safety and reliability are satisfactory; it achieves good economic and social benefits. |
