  • Publication number: 20210348548
    Abstract: Cross-port air flow that improves engine fuel economy and reduces pumping losses during part-throttle operation can be implemented in various types of internal combustion engine systems using ports that interconnect the intake ports of different cylinders, thus allowing different cylinders to share combustion air. Cross-port air flow is commenced during part-throttle engine operation to disrupt the primary combustion air flow from each throttle to its associated cylinder, which reduces charge density and engine power. The engine compensates for the reduced power by incrementally opening the throttles, thus increasing the primary combustion air flow, reducing pumping losses and improving fuel economy.

  • Patent number: 11149632
    Abstract: Methods and systems for damping an impact velocity in an engine system are provided. In one example, the engine system comprises a variable compression ratio (VCR) mechanism including a rod length adjustment assembly configured to adjust a distance between a crankshaft interface and a piston interface. The rod length adjustment assembly also includes a fluid control circuit including a damping cavity positioned between a first rod section and second rod section and configured to dampen a relative motion between the first and second rod sections during a compression ratio adjustment to reduce noise, vibration, and/or harshness (NVH).

  • Publication number: 20200072122
    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.
