| 摘要： | Currently the U.S. Army has two full-scale engine tests which are used for qualifying engine oils. Both tests are based on the Detroit Diesel 6V-53T engine with a number of similarities between the two test procedures. The first of these tests is Method 354, FTMS 791B for qualification of MIL-L-46167 arctic engine oils (OEA) while the other is the newly released Method 355T, FTMS 791B for qualification of MIL-L-2104D tactical engine oils (OE/HDO). One of the main differences between these two test /procedures is that the Method 354 procedure uses an aluminum engine block which is no longer available from the manufacturer. Other differences are that this method is run for a shorter test duration at a lower engine power output level under steady-state conditions. The unavailability of the case aluminum cylinder block from the manufacturer and the phase-out of Chis aluminum engine from the Military inventory means that Method 354 must be updated or replaced. This project was an attempt to develop a correlation between the two test methods by comparing results from Method 355T with results from Method 354 using the lubricants used in developing and standardizing Method 354. |
