The examination of injection strategies of jet propellant-8 for compression ignition engine with a low compression ratio

Fuel Communications, 2021
Jet Propellant-8 (JP-8) is used as a fuel for standard CI engine instead of diesel oil, especially in military applications on a large scale. For all such applications, the engine regulation parameters are optimal for diesel oil.
