Abstract
An excess oxygen reduction system includes a fuel cut-off condition module, an injector module, and a valve module. The fuel cut-off condition module determines whether a fuel cut-off condition exists. The injector module prevents a fuel injector from fueling a cylinder when said fuel cut-off condition exists. The valve module closes an impulse charging valve when said fuel cut-off condition exists.
