Ionization gas analyzer and method

A method for identifying gases using ionization voltage comprising the steps of:

• providing an ionization chamber including a plurality of ionization electrodes therein;
• providing a test gas within the ionization chamber;
• providing a plurality of variable high voltage pulses to the plurality of ionization electrodes from a high voltage generator;
• generating a plurality of ionization voltages from the plurality of variable high voltage pulses in an ionization voltage analyzer;
• and
• producing a gas code identifier from the ionization voltage analyzer in response to the plurality of ionization voltages.

A motor vehicle having an exhaust gas analyzer system comprising:

• an ionization chamber including a plurality of ionization electrodes contained therein, the ionization chamber containing a test gas;
• a high voltage generator coupled to the plurality of ionization electrodes, the high voltage generator for providing a plurality of variable high voltage pulses to the plurality of ionization electrodes;
• and
• an ionization voltage analyzer coupled to the ionization chamber, wherein the ionization voltage analyzer receives a plurality of ionization voltages from the plurality of ionization electrodes in response to the plurality of variable high voltage pulses, and produces a gas code identifier in response thereto.
