Abstract
Measurement of the operation of the accelerator pump of an internal combustion (IC) engine is provided while the engine is running under load by snapping the engine throttle from a steady state throttle position to a full throttle position and back within a time interval less than the response time of the engine power valve (enrichment valve), and comparing the relative magnitudes of the carbon monoxide (CO) and hydrocarbon (HC) constituents of the engine exhaust gas measured before and after the snap acceleration to provide an indication of the performance of the accelerator pump.
