Inspection Data for Spark Ignition Engines from Air Force Nontactical Vehicles (MEEP Project H79-1C, Synthetic Oils). Volume 2. Appendices

摘要

Many DOD vehicles are operated under short-trip, 'stop and go' conditions. Since this type of operation imposes severe requirements on the engine oil and because poor performance and failure in the engine oil increase operation and maintenance costs, the decision was made to test synthetic lubricants as a possible solution to the problem. Today's energy shortage, rising labor and material cost, and smaller budgets require exploration of potential methods of cost reductions in operation of government vehicles. This MEEP project was requested by the Triservices through the Joint Deputies for Laboratory Committee (JDLC). Of approximately 450 general-purpose vehicles selected by 11 Air Force installations for this program, 29 of the vehicles were chosen for engine inspection at USAFLRL, San Antonio, TX. Based solely on the results of the engine tear-down inspections and in consideration of the data developed from oil analyses and maintenance records, synthetic lubricants can be successfully used in spark ignition engines. Statistical studies revealed no significant differences could be determined which would clearly indicate if the use of any one test oil would be more advantageous that the use of any of the other test lubricants. Final conclusions, of course, reside with the Warner Robins Air Logistics Center where coordination of the compilation of a report covering all aspects of the program will be made.
