A METHOD AND APPARATUS FOR CONTROLLING LOCOMOTIVE SMOKE EMISSIONS DURING TRANSIENT OPERATION

摘要

A method and apparatus for reducing the smoke emissions of a railroad locomotive during throttle notch changes. For certain throttle notch increases the present invention advances the engine timing angle and controls application of the load at the new throttle notch position, according to certain predetermined parameters. These strategies, when used together or separately, minimize visible smoke during transient operation.
