Cummins 903, Low Viscosity Synthetic Oil Test
Abstract
A 400 hour modified NATO endurance test was conducted to assess the performance and endurance of the Cummins 903 engine using the Single Common Powertrain Lubricant (SCPL) developed by TARDEC's Fuels and Lubricants Technology Team (FLTT). The FLTT group in building 210 provided the funding to purchase the Cummins 903 engine and supplied the SCPL that was used during testing. The test was run to look at the engines performance and endurance throughout the 400-hour test along with comparing the engine to previous engine data that was obtained at the same test conditions using standard 15W-40 engine oil. Test conditions are as follows, standard conditions for performance testing only: 77 deg F ambient air and 86 deg F fuel supply temperature, modified desert operating conditions for performance and 400 hour endurance testing: 120 deg F ambient air and 175 deg F fuel supply temperature. The Cummins 903 using SCPL passed the 400-hour modified NATO engine test conducted at desert-like operating conditions. The data showed the engine to perform well while operating with SCPL during the 400-hour endurance test under desert operating conditions, although anomalies in oil pressure and an oil leak after the 400-hour endurance test were noted. TARDEC's Fuels and Lubricant Research Facility at Southwest Research Institute has been commissioned to tear down the engine, conduct a complete analysis of the engines condition and provide a report on their findings.
