Abstract: Synergistic induction and turbocharging includes the use of one or more throttles in close proximity to each cylinder intake valve to control air flow in each intake port delivering air to combustion cylinders in an internal combustion engine system. A turbocharger may also be affixed in close proximity to each cylinder exhaust valve to enable a synergistic combination of hyper-filling cylinders with combustion air and immediate harvesting of exhaust gas by adjacent turbochargers. In some implementations the turbochargers may be low-inertia turbochargers. The combination of individual throttles per intake port and a turbocharger in close proximity to each cylinder enables faster ramp-up of an engine in the early stages of acceleration. Various implementations thus provide improved fuel economy and improved engine performance in tandem, instead of one at the expense of the other.

Abstract: An internal combustion engine has two exhaust valves (24, 25) per combustion chamber (21), and variable valve timing for each exhaust valve. The exhaust valves (24, 25) are associated with respective exhaust tracts (26, 27) including a turbocompounder (31) and a turbocharger (41). The turbine exhaust from one of the turbomachines is directed to turbine inlet of another of the turbomachines.

Abstract: A system includes a controller that is configured to respond to engine load being at a designated engine load point by operating an engine with a lower exhaust gas recirculation (EGR) amount and a more advanced fuel injection timing than any other steady-state engine load point when EGR and fuel injection are enabled. The controller is further configured to respond to engine load being within a range of engine load points around the designated engine load point by increasing the EGR amount and retarding fuel injection timing as load increases and as load decreases away from the designated engine load point. This may result in decreased fuel consumption while maintaining emissions below designated levels.

Abstract: Methods are provided for identifying degradation in components of a compressor recirculation valve (CRV). One method includes differentiating between degradation of a throttle of the CRV and a position sensor of the CRV based on each of a throttle inlet pressure and commanded position of the throttle of the CRV. The method also includes utilizing output from the position sensor of the CRV in response to the commanded position of the throttle of the CRV.

Abstract: Methods and systems are provided for diagnosing an intake oxygen sensor. In one example, a method may include indicating degradation of an intake oxygen sensor based on a first time constant of an output of the intake oxygen sensor and a second time constant of an output of a throttle inlet pressure sensor. The method may further include adjusting EGR flow based on the output of the intake oxygen sensor and the output of the throttle inlet pressure sensor when the intake oxygen sensor is not degraded.

Abstract: A turbocharger system comprises a first relatively small turbocharger and a second relatively large turbocharger connected in series and an exhaust gas flow control valve. The exhaust control valve has an inlet port communicating with the exhaust gas flow upstream of the first turbine a first outlet port communicating with the exhaust flow downstream of said first turbine but upstream of said second turbine, and a second outlet port communicating with the exhaust flow downstream of said second turbine. The valve is operable to selectively permit or block flow through the first and second outlet ports.

Abstract: A multi-stage exhaust turbocharger has parallel high pressure stages (30, 40) and a single low pressure stage in series. The high pressure stages (30, 40) have variable geometry turbines. The low pressure stage (60) has a divided scroll turbine wheel (62) with each scroll fed independently from the respective turbines of the high pressure stages. Valves V1, V2 determine flow paths to the respective turbines to ensure series, sequential operation.
