Full-Scale Engine Performance Characteristics of AVIATION SAFETY-TYPE FUELS

TESTS conducted on a full-scale aircraft engine show that satisfactory engine operation can be obtained at warmed-up conditions with low-volatility fuels of the safety type.

The engine used in the tests was modified for direct cylinder fuel injection, as fuels of this type are not sufficently volatile to be satisfactorily vaporized by means of a carburetor induction system.

Knock-limited performance, specific fuel consumption, and oil dilution characteristics were studied in these tests.
