Lack of fuel lubrication performance associated with JP-8 in modern diesel engines equipped with High Pressure Common Rail fuel systems can lead to premature performance loss or field failure. As engines in the Army fleet are replaced with modern engines, provisions for JP-8 fuel compatibility will need to be addressed by engine OEM s. Analytical Engineering, Inc. proposes to partner with Cummins Inc. Fuel Systems in a Phase I effort to define which components in a modern pump are susceptible to lubricity related failure when using JP-8 and high/low sulfur fuels. This effort will culminate in a definition of identified components and potential metallurgical and / or ceramic material modifications needed for fuel compatibility.
