Variable Compression Ratio - Production

Production

Variable compression engines have existed for decades but only in laboratories for the purposes of studying combustion processes. These designs usually have a second adjustable piston set in the head opposing the working piston. (very much like model aircraft 'Diesel' engines) Variable compression engines have been highly desirable but technically unobtainable for production vehicles due to the mechanical complexity and difficulty of controlling all of the parameters. The advances in low cost microcontrollers and a wealth of experience in their application to engine management now makes the control possible.

Famous quotes containing the word production:

    “The production of obscurity in Paris compares to the production of motor cars in Detroit in the great period of American industry.”
    —Ernest Gellner (b. 1925)

    “To expect to increase prices and then to maintain them at a higher level by means of a plan which must of necessity increase production while decreasing consumption is to fly in the face of an economic law as well established as any law of nature.”
    —Calvin Coolidge (1872–1933)

    “The problem of culture is seldom grasped correctly. The goal of a culture is not the greatest possible happiness of a people, nor is it the unhindered development of all their talents; instead, culture shows itself in the correct proportion of these developments. Its aim points beyond earthly happiness: the production of great works is the aim of culture.”
    —Friedrich Nietzsche (1844–1900)
