摘要： A method for extending the low-load operation of a homogeneous charge compression ignition engine includes employing a valve actuation device creating a negative valve overlap, thereby trapping and recompressing combusted gases within a combustion chamber, the device effecting increasingly longer negative valve overlap as engine load decreases, injecting during the negative valve overlap a fraction of fuel into the recompressed combusted gases, and igniting the fuel with a heat source during the negative valve overlap.

摘要： The profile of a tool or other object having a flat reference plane is illuminated by interfering beams of coherent light to generate a striped light pattern which at any point deviates from straight lines as a function of the surface spacing from the reference plane. A camera image of the pattern taken at an angle to the beams is processed by an image analysis program which converts the stripes to lines corresponding to light peaks and valleys of the pattern. Tool wear or object profile is determined from the deviation of lines from straight reference lines. The program includes algorithms for identifying peak and valley line segments, determining the segments which are neighbors of other segments, and connecting lines according to a set of rules and constraints which use the data on neighbor segments and the proximity of segment end points.
