Abstract
Systems and methods for improving emissions of an internal combustion engine are presented. In one example, engine crankshaft acceleration is a basis for estimating engine air-fuel ratio during engine starting when output of an oxygen sensor may be unavailable. An actual engine air-fuel ratio may be adjusted in response to the estimated engine air-fuel ratio.
