Abstract: Systems and methods of reducing the emissions of vehicles having a spark ignited internal combustion engine are provided. When the exhaust temperature is less than a set point temperature, the oxygen concentration of the exhaust is increased as the exhaust passes from a first stage catalytic converter to a second stage catalytic converter. The increased oxygen content of the exhaust improves the removal efficiency of carbon monoxide and/or hydrocarbons at the second stage catalytic converter without (or with minimal) reforming nitrogen oxide compounds. The oxygen concentration of the exhaust is not increased when the exhaust temperature is greater than the set point temperature.

Abstract: Methods and apparatus for removing undesired pollutants from exhausts streams of spark-ignited internal-combustion engines in vehicles while producing electrical energy as a byproduct. The apparatus includes a reduction catalyst, a thermoelectric generator (TEG), and an oxidation catalyst. The TEG cools the exhaust stream and generates electricity. The exhaust stream is oxygenated after passing through the TEG and prior to passing through the oxidation catalyst.

Abstract: A system and method for controlling an internal combustion engine and electrical inverter system for powering a load, including controlling the operation of a spark-ignited internal combustion engine prime mover used in generation of electrical power by way of a generator. A microprocessor (e.g., DSP) controlled circuit taking engine speed input from an engine speed signal is used to control the operation of the internal combustion engine prime mover so that it is preferably operated substantially at wide open throttle.
