Abstract
A study was conducted to investigate the effects of diesel fuel lubricity on diesel engine fuel injection equipment (FIE) wear and failure rates, for diesel fuels with poor to moderate lubricity characteristics, with and without lubricity additives. Five tests were used to evaluate diesel fuel lubricity characteristics: 1) a modified Falex Corporation Ball-on-Three-Disk (BOTD) lubricity test rig; 2) a high-speed Detroit Diesel Corporation (DDC) 8V71T engine test rig operated at maximum load and speed conditions under elevated fuel, coolant and ambient temperatures; 3) a Wärtsilä VASA 9R32, medium-speed, diesel engine electric power generation unit in Iqaluit, Nunavut, Canada, 4) a fuel pump rig (FPR) and 5) a high frequency reciprocating rig (HFRR).
Conclusions drawn from the BOTD, DDC 8V71T, VASA 9R32, FPR and HFRR test results indicate that several lubricity additives, added to diesel fuel at concentrations from 70 ppm to 400 ppm, are capable of: 1) improving the lubricity of poor lubricity diesel fuels to satisfactory levels and 2) substantially reducing FIE wear rates. The BOTD was shown to have the best correlation with the DDC 8V71T and FPR tests with and without lubricity additives. The BOTD fuel lubricity bench test and associated proposed ASTM test method was found to be capable of determining fuel lubricity for fuels, with and without lubricity additives. The BOTD also appeared to be a reasonable indicator of the potential performance of the diesel fuel used in the VASA 9R32 tests. The BOTD was capable of doing this in a short time frame (less than 3 hours) using a 35 ml (1.2 US fl. oz) sample of test fuel.
