Abstract: A method of operating an engine includes operating the engine in first and second engine operating map regions by performing passive jet ignition combustion with a first stoichiometric fuel mixture and a first volume of residual gas. The engine is operated in a third engine operating map region by performing turbulent jet controlled compression ignition (TJCCI) with an ultra lean fuel mixture and a first volume of cooled exhaust gas recirculation, a fourth engine operating map region by performing passive jet ignition combustion with a third stoichiometric fuel mixture and a second volume of cooled exhaust gas recirculation, and a fifth engine operating map region, characterized by shutting off the engine. The engine is operated in a mode transition region between the second, third, and fourth engine operating map regions by performing passive jet ignition combustion with a second stoichiometric fuel mixture and a second volume of residual gas.

Abstract: A hybrid machine includes an engine, a first and second motor, a first and second generator, and a first and second geartrain. The engine generates power from a combustion reaction and includes an intake port, a combustion chamber, a piston, a crankshaft, and an exhaust port. The intake port receives air from an external environment. The combustion chamber mixes the air with fuel to create a mixture that is ignited. The piston actuates to rotate the crankshaft. The exhaust port delivers exhaust gases out of the engine. The first and second motors respectively include a first and second hub that rotate from supplied power. The first and second generators respectively generate power when a first and second shaft rotate. A first and second geartrain respectively connect to the first and second motors, the first and second generators, and the crankshaft to transmit power to a first and second wheel.
