Supercharged engine and method of control
Methods and systems for minimizing the power consumed by a supercharger pump in an engine system. The methods and systems minimize the delta pressure across the pump with a control strategy for positioning the electronic throttle and supercharger bypass valve in a coordinated manner to deliver the required amount of fresh air flow into engine (i.e., the air flow associated with the driver's requested torque), while, at the same time, minimizing the power consumed by the supercharger pump for best fuel economy..

Deceleration fuel shut off for carbureted engines
Fuel efficiency of small carbureted engines can be improved through the use of a fuel shut off valve that ceases fuel flow in the carburetor upon determination that the engine throttle has been closed and the engine is not at or near an idle condition.. .

Method for controlling rail pressure
Proposed is a method for closed loop rail pressure control of a v-type internal combustion engine with an asymmetrical firing order, wherein an actual rail pressure is computed from the measured rail pressure; a system deviation is determined by means of the actual rail pressure and a set rail pressure; and wherein a correcting variable for actuating a pressure actuating element, in particular a suction throttle, for regulating the rail pressure is computed. The invention is characterized by the fact that the actual rail pressure is computed from the measured rail pressure by means of an averaging filter in that below a limit speed (nli) the rail pressure is averaged over a constant time and in that above the limit speed (nli) the rail pressure is averaged over a working cycle of the internal combustion engine..

Data rate throttling
The throttling of mobile device data rates is provided at events, e.g., sporting events, and other venues with large, dense crowds. The system can monitor the loading of the mobile radio antennas at the venue, and when the loading reaches a threshold loading point, the system can selectively throttle the data rates of mobile devices at the venue.

Piston pump for delivering fluids, and associated vehicle brake system
A piston pump for delivering fluids comprises a piston, a cylinder element and a pressure chamber which is arranged between an inlet valve and an outlet valve and is closed by a cover, wherein means for throttling the fluid flow are provided in the fluid flow downstream of the outlet valve, and a vehicle brake system has a piston pump of this type. The throttle means comprises a movable annular disc which is guided on the cylinder element and the internal diameter of which is adapted to the external diameter of the cylinder element, wherein the axial travel of the annular disc sets a variable first throttle cross section..
