Advanced Opposed-piston 2-stroke Diesel Demonstrator

Tactical and operational missions require equipment powered by lightweight, high output 50 to 150+ BHP engines. Engine powered equipment in this size is predominately 2-cycle diesel. Department of Defense (DoD) has mandated the use of heavy fuels: jetand diesel. Next generation fuel efficient, lightweight, high power density (1.5 HP/in3 disp.), heavy fuel engines (HFE) are needed. TARDEC will research opposed-piston (OP) 2-cycle diesel engines incorporating advanced 2- and 4-cycle dieseltechnologies. Design concepts will be evaluated by building a single cylinder research engine. AED Corp.'s proposed design combines its extensive hardware developed HFE direct-injected controlled combustion engine technology with electronicallycontrolled common rail fuel injection, variable nozzle turbocharger, cooled articulated pistons, and high turbulent combustion chamber. Using Detroit Diesel Corp.'s (DDC) production 2-cycle components, the engine's design will facilitate hardware changesneeded to evaluate critical design variables (i.e. crankshaft phasing). Operating on a controlled dual combustion thermodynamic cycle limiting maximum cylinder pressure, exceptionally high power density, low fuel consumption, and low emissions arepredicted. Phase I work has confirmed that DDC 71 & 92 series components can make up the majority of components in the mechanical engine structure. Proof of concept will occur during the Phase I Option, Concept Engine Testing. The Phase II fullyinstrumented Advanced Demonstrator Model (ADM) design, build, development and operational testing will evaluate and optimize the OP engine to determine its potential for future military and commercial use.
