The Performance of a Spark-Ignited Stratified-Charge Two Stroke Engine Operating on a Kerosine Based Aviation Fuel 972737
This study examines the feasibility of broadening the fuel capabilities of a direct-injected two-stroke engine with stratified combustion. A three cylinder, direct-injected two-stroke engine was modified to operate on JP-5, a kerosene-based jet fuel that is heavier, more viscous, and less volatile than gasoline. Demonstration of engine operation with such a fuel after appropriate design modifications would significantly enhance the utilization of this engine in a variety of applications. Results have indicated that the performance characteristics of this engine with jet fuel are similar to that of gasoline with respect to torque and power output at low speeds and loads, but the engine's performance is hampered at the higher speeds and loads by the occurrence of knock. Although full load engine operation was never achieved with JP-5 without knock present, the severity of such a limitation was decreased or eliminated through much of its operating range with minor changes in engine design and operating variables.
