摘要： Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency or the engine.

摘要： Disclosed is a control system and method for controlling a superturbocharged engine system in various operation modes. Throttle control mode may idle the superturbocharger during low and medium engine loads, so that boost is not created in the intake manifold. During high engine load conditions (open throttle), boosting occurs in response to the driver, operator, or control system requesting increased engine loads. For transient control mode, the control system may respond to transient conditions in response to engine speed and load so that the engine does not bog down or overcome vehicle traction limits. The control system may also predict future operating points.

摘要： Disclosed is a symmetrical traction drive that utilizes multi-diameter rollers having traction surfaces for transferring rotational mechanical energy between the shaft and a transfer gear. Multi-diameter rollers are mounted in carriers disposed between two substantially symmetrical ring gears. Sloped traction surfaces of the ring gears mate with inner traction surfaces on both sides of the multi-diameter rollers. Since force is applied to the inner traction surfaces on both sides of the multi-diameter rollers, forces are substantially equalized on each side of the multi-diameter rollers. An outer traction surface of the multi-diameter roller interfaces with a traction surface on the shaft. Speed reduction ratios of at least 20:1 or greater can be achieved. The high speed drive may include exhaust turbines, steam turbines, including a Tesla turbine or Schumacher turbine, compressors, combinations of turbines and compressors, high speed pumps, dentist drills, or other devices that operate with high rotational speed.

For transient control mode, the control system may respond to transient conditions in response to engine speed and load so that the engine does not bog down or overcome vehicle traction limits. The control system may also predict future operating points. For steady state control mode, the control system may receive a plurality of input data, an actual/current control data input, look up a desired value for the control input, compare the desired to the actual control input, and perform control logic on the comparison results to obtain an updated continuously variable transmission ratio to control the superturbocharged engine system independent of throttling on the engine.
