  • Patent number: 9988974
    Abstract: An exhaust gas turbocharger with a wastegate port configured to permit some exhaust gas flow to exit a turbine volute upstream of the turbine wheel and enter a bypass channel thereby bypassing the turbine wheel, a valve with a valve head dimensioned to seat on a valve seat and to move between a seated position and an open position, the bypass channel having a sidewall contoured to surround the valve head as the valve head moves between the seated position and the open position, he bypass channel sidewall shaped so that a throat area (At) area between the bypass channel sidewall and valve head gradually increases as the valve head moves between the seated and the open position, such the bypass flow is controlled by the throat area (At) and not the area between the valve head and the valve seat.

  • Patent number: 9957822
    Abstract: An asymmetric twin scroll turbine 10 combined with an integrated exhaust manifold cylinder head 20 may be designed to accommodate mixed, radial or axial flow turbines. The asymmetric twin scroll turbine 10 includes a first scroll 11 and second scroll 12 wherein the first scroll 11 is larger and has greater mass flow capacity than the second scroll 12. The larger volute increases flow capacity and counteracts backpressure creating evenly balanced or equalized peak pressures and pulsations between both volutes and balancing of gas flow between cylinder sets. By equalizing peak pressures, pulsations, and gas flow between cylinder sets, engine self-ignition can be avoided in the cylinder set that would have had the largest peak pressures and pulsations. By in creasing flow capacity of the larger volute and balancing gas flow between cylinder sets, the turbine pressure differential is reduced and the engine can operate more efficiently, improving fuel economy.

  • Patent number: 9957945
    Abstract: Disclosed is an inventive method for controlling a corona ignition device of an internal combustion engine. A corona discharge, which ignites fuel in a combustion chamber of the engine, is generated by applying a voltage to the corona ignition device. An actual value that is characteristic of the nitrogen oxide concentration of the exhaust gas is compared with a setpoint value, and, if the actual value deviates from the setpoint value by more than a specified threshold value and the actual value is greater than the setpoint value, the voltage is reduced after the comparison.

  • Patent number: 9951793
    Abstract: A compressor housing may include a shroud portion which is axially spaced from an inlet portion and configured to at least partially surround the compressor wheel. The compressor housing may be further configured to include a recirculation cavity which is formed between an exterior surface of the shroud portion and an interior surface of the compressor housing. Furthermore, a recirculation slot may define an airflow pathway between the recirculation cavity and the compressor wheel. Additionally, the compressor housing may include an angled shroud support extending radially through the recirculation cavity from the exterior surface of the shroud portion to the interior surface of the compressor housing. The angled shroud support may be spaced an axial distance away from the recirculation slot to reduce turbulence in the airflow as the airflow moves from the recirculation cavity to the compressor wheel.
