  • Vehicle gas emission sampling and analysis assembly
    Publication number: 20020026822
    Abstract: A vehicle gas emission analyzer assembly for a vehicle having a passenger compartment includes a gas analyzer system adapted to determine concentration and/or mass flow of at least one exhaust gas of an internal combustion engine. The analyzer may include a particular housing for the gas analyzer system. The gas analyzer system may include a hydrocarbon gas analyzer that is operated at a temperature that is sufficiently high to reduce deposits of hydrocarbon molecules present in the sample gas. The gas analyzer may include an ultraviolet source including a discharge lamp having a discrete emission line at an absorption frequency for a particular nitrogen-based gas.

  • PC compatible modular based diagnostic system
    Patent number: 5659680
    Abstract: A PC-based diagnostic system is modular-based, and includes a motherboard, a backplane board, a PCMCIA board, and a keypad adapter board. The motherboard communicates with I/O modules connected to the backplane board, PCMCIA modules connected to the PCMCIA board, and with a keypad or a mouse through the keypad adapter board. Based on the type of device to be tested, various diagnostic programs can be accessed internally to provide the signals used to perform the test. A system controller and a processor are provided on the motherboard to control the transfer of data and control from the motherboard, through the backplane, and to the I/O modules. Additional select lines are provided to select one or more I/O modules during a test. An ISA bus is also provided in a standard arrangement.

  • Method of analyzing vehicle emissions and in-flight gas analysis apparatus
    Patent number: 5099680
    Abstract: A method and apparatus for measuring the concentration of one or more emission gases in the exhaust of a vehicle, including a conventional gas analyzer and a transducer for monitoring at least one parameter directly related to the operating condition of the vehicle. Samples of gas emissions are supplied to the gas analyzer and the transducer is monitored while the vehicle is operated in a convention manner. A running history of readings of exhaust gas concentration(s) of interest is maintained during vehicle operation with earlier readings being supplanted by recent ones. Upon the occurrence of a predetermined event, the running history is preserved in order to provide a correlation between the exhaust gas concentrations and known operating parameters of the vehicle.
