Abstract
An engine control system is disclosed for reducing the hydrocarbon content in the exhaust gas of a crankcase scavenged, two-stroke engine in the operating range near idle, with light operator induced engine loading. As operator demand for engine output power is increased, the system increases the fuel per cylinder supplied to the engine while restricting the supplied mass of air per cylinder to a value less than that flowing at unloaded engine idle.
