Based upon initial testing, it was concluded that the T64 engine could operate on emulsified fuel (JD1) without any engine or control adjustment or modifications. This was accomplished without loss of performance or deterioration of engine components. However, the limited program indicated that water additives had severe effects on fuel system components which meet normal Military Specification corrosion resistance requirements. Extensive follow-on testing for fuels and long term engine endurance operation are required to evaluate these fuels fully from an engine life standpoint.
This paper summarizes engine operation, and decribes components following limited operation on a water emulsification of JP4.
