  • Publication number: 20030106541
    Abstract: The present invention relates to an electronically driven pressure boosting system that is used to boost the torque output of an internal combustion engine. Engine operating parameters are fed to an engine control unit (ECU). A supercharger is controlled by the ECU and when powered by an electrical supply system boosts engine torque. When the supercharger is in an idle mode of operation at low supercharger speeds it does not boost torque, and when it is in a boost mode of operation at high supercharger speeds, it does boost engine toque. The supercharger requires a lag time to accelerate from an idle speed to a boost speed. The electronic control system monitors the engine operating parameter(s) and calculates therefrom a likelihood that the engine torque will need to be boosted by the compressor.

  • Patent number: 6273076
    Abstract: The performance of a compression ignition internal combustion engine is improved by optimizing excess air ratio (lambda) and/or intake air charge temperature (ACT) on a full time, full range basis. The basic procedure is to first determine the desired or optimum lambda and then to control ACT and intake manifold absolute pressure (MAP) to maintain them at the optimum values for the fuel quantity required at a particular operating point. This approach allows control of both temperature and pressure of the air entering the engine. Full range control requires that lambda and ACT be controlled both upward and downward to achieve optimal engine performance. Control of both lambda and ACT is further enhanced through the use of a supercharger with adjustable input power installed in series with a standard turbocharger compressor of the engine.
