Abstract

A computerized analyzer for rapid diagnosis of an apparatus, which, by way of example may be an automotive vehicle. In such an application, the analyzer will read and/or compare the vehicle specifications to the related actual vehicle condition. The analyzer will also record either of these readings.

Claims

1. An apparatus for analyzing various condition signals received from an internal combustion engine to be tested comprising:

a. an information storage device for storing specification information and producing selected specification signals when addressed;

b. computer means for receiving said specification signals and converting them to usable voltages;

c. kill circuit means for disabling selected cylinders of said engine;

d. control means including numeric input means for addressing the storage device to select and initiate retrieval of specification information from said storage device, said control means further including numeric indicator means disposed for response to signals from said computer to display the firing order of said engine, said numeric input means operatively connected to said kill circuit means to disable a desired cylinder of said engine, and said numeric indicator means disposed for receiving signals from said kill circuit through said computer for indicating the disabled cylinder; and

, e. power supply means for operating each component of the test apparatus.

2. An apparatus as set forth in claim 1 wherein said numeric indicator means in response to selected sequential control and computer signals displays specific test information in addition to said firing-order display.

3. An apparatus as set forth in claim 2 (1) wherein said control means includes numeric indicator means for simultaneous display of the specification information address and tHe test mode.

4. An apparatus as set forth in claim 1 including additional indicator means for receiving said usable voltages and for comparison thereof to condition signals to be tested, and for selectively indicating the usable voltages, the condition signals and the comparison of the two.

5. An apparatus as set forth in claim 4 wherein said second-mentioned indicator means comprises a unitary structure disposed for selectively receiving the specification signals and the condition signals for comparison and display thereof.

6. An apparatus as set forth in claim 5 wherein said unitary indicator means and said computer means include means for identification of the parameter of condition and specification signals being received.

7. An apparatus as set forth in claim 4 (1) wherein said apparatus includes means for selectively producing a printed record of said specification signals, said condition signals and said comparison of the two.
