    Abstract: A voltage-controlled delay line (VCDL) comprises a series of delay cells outputting a clock output signal having a delay relative to a clock input signal input to the series of delay cells. A duty-cycle correction section corrects the duty cycle of the clock output signal by providing opposite current outputs which are fed back to the series of delay cells to substantially simultaneously charge and discharge current of the series of delay cells in opposite directions. A control current input to the series of delay cells controls the amount of the delay. A voltage-to-current converter converts a control voltage into the control current so that the delay changes substantially linearly as the control voltage changes. The method for using the VCDL to produce linear delay is also included. The VCDL can be used in a delay-locked loop (DLL).

    Abstract: A computer readable storage medium having stored data representing instructions for controlling a spark ignited direct injection internal combustion engine having a plurality of cylinders operable in at least homogeneous and stratified modes, includes instructions for determining a desired value for an engine operating parameter based on current engine operating conditions wherein the desired value results in scheduling of an air/fuel ratio between homogeneous range and stratified range of allowable air/fuel ratios, instructions for operating a first portion of the cylinders in the homogenous operating mode, and instructions for operating a second portion of the cylinders in the stratified operating mode such that a combined air/fuel ratio associated with the first and second portions of the cylinders approaches the scheduled air/fuel ratio.

    Abstract: A method for controlling mode transitions, such as from stratified to homogeneous mode, in a direct injection engine adjusts a number of cylinders carrying out combustion to prevent engine torque disturbances. Cylinder activation is used when changes in cylinder air/fuel ratio cannot be compensated using ignition timing adjustments. In addition, the number of cylinders to activate is also determined and measures are taken if the number of cylinders determined are not available to be activated.

    Abstract: A speed control system is shown for an internal combustion engine (10) having an intake manifold (44) and throttling device (96) connected thereto in parallel with the main throttle plate (62). After an idle speed command is detected (200), the engine (10) is decelerated (204-230) to a preselected speed by adjusting the throttling device (96) to concurrently force both engine speed and engine acceleration within a predetermined acceleration/speed range(s). When the preselected speed is reached, engine speed is regulated (300-328) to a desired idle speed by adjusting the throttling device (96) to force a difference between the engine and idle speed towards zero.
