The volume flow regulating valve is composed of a cylinder with a dual piston mounted axially displaceably in the cylinder, with a central pressure chamber being formed in the region of the barbell-shaped central piece of the dual piston. Aside from an inlet for the fluid medium, it is also the case that the two outlet ducts are provided at the central pressure chamber. The outlet ducts are arranged on the cylinder with such an axial spacing that—when the dual piston is situated in a central position in relation to the two outlet ducts—the first outlet duct—preferably partially covered by the first piston—and the second outlet duct—preferably partially covered by the second piston—each open up an equal opening cross-sectional area.

  • Patent number: 9765685
    Abstract: Systems, methods, apparatus provide improved turbocharging of an internal combustion engine. A single, discrete turbocharger is affixed to each engine combustion cylinder. Turbochargers can be mounted to their associated cylinders in close proximity, thus harvesting higher energy exhaust gases from each combustion cylinder. Tip in and spool up responses can be further improved using low rotational inertia turbochargers that can operate effectively across a wide range of engine operational speeds. Controlled balancing valves between cylinder exhaust lines can deliver exhaust gases from a single cylinder selectively to multiple turbochargers in appropriate operational conditions. Moreover, multiple turbochargers' compressors can be configured in series to achieve pressurization compounding of combustion air for low RPM operation. Nesting of turbochargers relative to one another permits improved mounting of each turbocharger in close proximity to its corresponding combustion cylinder.

  • Patent number: 9726074
    Abstract: A turbocharger includes: an inflow passage to guide a fluid to a housing space for a turbine wheel; an exhaust passage to discharge the fluid having rotated the turbine wheel from a turbocharger body; a bypass passage connecting the inflow passage and the exhaust passage; a valve unit having one valve for a communicating portion between the exhaust passage and the housing space, and another valve for the bypass passage; an actuator to turn the valve unit and a stem connected to the valve unit about an axis of the stem; and a controller to operate the actuator. The controller adjusts the opening of the bypass passage by turning the valve unit within a specific range about the axis of the stem when a specific condition is met, and closes the exhaust passage by turning the valve unit beyond the specific range when the specific condition is not met.

  • Patent number: 9631551
    Abstract: An internal combustion engine includes working cylinders and a fresh gas line for supplying fresh gas to the working cylinders. The fresh gas line has a charge air section. A mechanically driven compressor is disposed in the charge air section of the fresh gas line. An air control/shut-off flap is disposed in the charge air section such that, in dependence on a position of the air control/shut-off flap, a gas mass flow in the charge air section flows completely or partially via the mechanically driven compressor or flows past the mechanically driven compressor. A method for operating an internal combustion engine is also provided.

  • Patent number: 9605588
    Abstract: A supercharger (15) is provided with a bypass pathway (17). A backflow preventer (20) is provided to the air intake pathway (8) between an airflow meter (10) and the bypass pathway (17). The backflow preventer (20) has: a casing (41) formed by locally expanding the cross-sectional area of the air intake pathway; and an inner tube (42) substantially constructing a duct for the mainstream of air intake. The inner tube (42) is supported by a flange portion (50) and the downstream end (42a) opens within the casing (41). During backflow when the bypass pathway (17) opens, a portion of the intake air enters into an exit-side space section (55), and the flow is prevented by the flange portion (50). Consequently, reverse flow is suppressed.

  • Patent number: 9574489
    Abstract: A turbocharger control system for an internal combustion engine having first and second turbochargers connected in series includes first and second pressure sensors, and a controller. The first and second pressure sensors are disposed in an air intake of the engine, and are configured to sense boost pressure of the first and second turbochargers, respectively. The controller is configured to receive pressure signals from the first and second pressure sensors, and to control operation of at least one of the first and second turbochargers to maintain a desired boost pressure ratio.

  • Patent number: 9528430
    Abstract: Systems and methods for compensating for deposits that may accumulate within a compressor recirculation valve positioned in parallel with a turbocharger compressor are presented. The systems and methods adjust actuators to maintain engine operation such that it may be more difficult for a driver to become aware that a compressor recirculation valve diagnostic is being executed.
