Abstract
An engine control scheme determines the appropriate and desired magnitude of scavenging air flow for a two stroke engine as a function of both load and engine speed. The desired air flow is determined, as a function of engine load and engine speed, to achieve an optimal magnitude of emissions within the exhaust stream and to also optimize a reverse thrust capabilities of the marine propulsion system.
