STEADY-STATE AND TRANSIENT A/F CONTROL REQUIREMENTS FOR COLD OPERATION OF A 1.6 LITER ENGINE WITH SINGLE-POINT FUEL INJECTION
An engine dynamometer test facility capable of controlling temperatures from 0 deg F to 150 deg F was used to investigate A/F control characteristics of a 1.6 liter engine with single point fuel injection. Two types of tests were run. In the first, the effect of induction system temperature on manifold wall wetting and transient A/F control was determined. In the second, a cold start procedure was developed to determine the effect of engine temperature on the percent of fuel which burns by observing exhaust A/F during steady state operation while the engine warms up. It was found that transient A/F control problems due to manifold wall wetting are much greater than steady state problems associated with incomplete fuel burning.
