    摘要： A diagnostic system includes a host system having a processor, storage media and a user interface including a display screen, and a plurality of support data sources, which may be resident at or remote from the host system. The storage media stores service or maintenance test designations and descriptions. System software responds to user selection of displayed vehicle systems or symptoms to be diagnosed by displaying test designations. Upon user selection of a test designation, the system displays the first page of the test description and simultaneously links to appropriate support data sources and displays pertinent support data on a portion of the display screen. A method includes selecting and displaying test descriptions and, in response to each such display, automatically retrieving and displaying related data from a support data source.

    摘要： An improved automated engine diagnosing device employing a digital data processor and a cathode ray tube monitor for displaying individual engine cylinder numbers in separate association with correlated values of exhaust gas emissions pollutants. Engine timing data associated with the time of firing of individual cylinders of the engine being tested synchronizes select cylinder firing inhibition for orderly accumulating gas emissions data generated from an exhaust probe placed in the tail pipe of the automobile under test. An automatic sequential firing inhibition and a manually selectable firing inhibition permits dual modes of data acquisition for developing pollutant data to be utilized by the processor for generating the analysis display on the cathode ray tube monitor.

    摘要： A processing unit for normalizing the output data of a gas analyzer in view of zero adjustment data and gain adjustment data formulated by the processing unit controlling air input and span reference simulation of a reference gas. A voltage reference generator is manually variable for calibrating the system while passing a known reference gas through the analyzer, in order to provide a scaling factor for use during output data adjustment. A hold switch is manually actuable by the operator for storing in memory the value of a gas analyzation voltage for permitting adjustment to the output data after the gas is removed from the cell of the analyzer.

    摘要： A wheel balancer comprises apparatus for determining the radius of a rim of a hub of a wheel and for determining the distance of the inner and outer side walls of the hub from a reference plane. A framework which is pivotal downwardly over the wheel to be balanced carries a pair of ultrasonic transducers to determine distance of the sides of the wheel from the reference plane. A transducer monitors the position of the framework. The distances monitored by the ultrasonic transducers are stored in a microprocessor against the corresponding positions of the framework at intervals on movement of the framework. The ultrasonic transducers detect a large change in distance from the reference plane caused by the hub well periphery. The hub rim radius is computed from the well periphery radius, while the distances of the side wall from the reference plane is obtained by looking up the stored values of distances which corresponds with the appropriate position of the framework for the hub rim radius.

    摘要： A method and apparatus of developing a stabilized power firing event signal for a cylinder in a wasted spark ignition system having pairs of complementarily connected cylinders, each with a spark plug connected to an opposite end of an independent ignition coil. The first and second firing event signals are developed for each spark plug upon firing of the ignition coil. The first and second signals are combined with like polarity in a summation circuit for eliminating common mode signal portions. The combined signal, which is now stabilized and accurately indicates spark duration, is used for capturing secondary ignition data and may be visually displayed for analysis.

    摘要： A method of determining the cylinder #1 power firing event in a wasted spark ignition system comprises developing a first signal comprising the integration of all power firing event signals, a second signal comprises the integration of all wasted firing event signals and comparing the amplitudes of the two signals to determine which represents the power firing events. The firing event signals are sorted for integration based upon knowledge of the polarity of spark plug firings, the cylinder firing order and the occurrence of a #1 cylinder firing event signal.
