Lubricity of liquefied gas - Assessment of the various pressure and temperature high-frequency reciprocating rig (VPT-HFRR)- LPG blended fuel for diesel engine

摘要

In this research, a test apparatus (VPT-HFRR) for evaluating lubricity was manufactured at an arbitrary pressure according to the lubricity test method (HFRR) for diesel fuel. The lubricity of LPG blended fuel (LBF) for diesel engines was examined using VPT-HFRR. This was a value close to that of diesel fuel, and when a suitable lubricity had been maintained, it was checked. Prototype trucks were manufactured and their durability was examined. After a run of 70,000 km or more, no serious trouble had occurred, and when LBF was maintained at a suitable lubricity, it was checked.
