Opposed piston engine

• 100% balance of internals (including primary, secondary, rocking, & rotary forces) reduces friction & wear

• 70% Lower piston friction, lower average piston speeds, & 100% balanced forces give smooth running

• 75% more valve head and curtain area per displacement lowers charge pumping energy needs

• 80% more area and better geometric access for injectors and / or spark plugs per displacement

• Lower individual & distributed con-rod and crankshaft forces reduces weight & reciprocating masses

• Higher power durations (200o) more power events / rev. and more power overlaps add smoothness

• Proprietary combustion chamber to engine block heat transfer reducing parts

• Air cooled, with no radiator, coolant, or coolant pump giving lower weight and cooling work losses

• 80% off-the-shelf, widely sourced parts give resiliency, lower build & repair costs, and improve logistics

• Our modular designs give build and use-case flexibility, upgrade paths, and reduce inventory needs

• Our balance plus low piston speeds give lower use costs, better maintenance intervals, and longer oil life
