Class Information
Number: 123/672
Name: Internal-combustion engines > Charge forming device (e.g., pollution control) > Including exhaust gas condition responsive means
Description: Subject matter wherein the means for forming the mixture of fuel and oxidant senses at least one characteristic or parameter of the products of combustion (e.g., composition, or temperature or pressure, etc.) and uses such information to modify the relative proportion or ratio of fuel and oxidant in the mixture supplied to the internal combustion engine.
