    摘要： A system and method for hydrogen rich exhaust gas recirculation are provided. The system includes the addition of a supplemental injector injecting additional natural gas beyond the stoichiometric point into one of the engine cylinders. After combustion, the exhaust of the cylinder remains high in hydrogen. The exhaust is then routed through a hydrogen rich exhaust path to an exhaust gas recirculation mixer where is it mixed with natural gas and exhaust gas from the other cylinders. The resultant mixture is then routed to all of the cylinders of the engine for improved combustion due to the additional hydrogen.

    摘要： A vehicle has a waste heat recovery (WHR) system and an engine. The WHR system includes a WHR working fluid circuit with a pump, a power turbine, and a condenser. An engine coolant circuit circulates coolant between the engine and an engine coolant heat exchanger/working fluid boiler in the WHR working fluid circuit. At least one exhaust gas heat exchanger/superheater in the WHR working fluid circuit receives waste heat from an exhaust circuit and/or from an exhaust gas recirculation circuit. A working fluid cooled charge air cooler in the WHR working fluid circuit receives waste heat from compressed charge air in a charge air intake circuit. A recuperator may transfer waste heat from working fluid passing from the power turbine to the condenser to working fluid passing from the working fluid cooled charge air cooler to the engine coolant heat exchanger/working fluid boiler.

    摘要： An exhaust gas recirculation venturi pump for drawing an exhaust gas from an exhaust manifold of an internal combustion engine through an exhaust gas recirculation system. The exhaust gas recirculation venturi pump includes a first passageway that at least in part is configured to provide a venturi effect using the flow of an air/fuel mixture through the exhaust gas recirculation venturi pump. At least the decrease in pressure of the air/fuel mixture created by the venturi effect may draw an exhaust gas from the exhaust manifold into the exhaust gas recirculation venturi pump. Moreover, the suction provided by the venturi effect may pull the exhaust gas through an exhaust gas recirculation system, even when the exhaust gas pressure at the exhaust gas manifold is equal to or greater than the pressure of the intake charge at the intake manifold.
