Patent ID: 8302401

Claim:
A method for supplying power with a diesel engine to an apparatus comprising: operating a diesel engine having at least one combustion chamber for accommodating air and combustible fuel, drivably connecting the diesel engine to the apparatus whereby the diesel engine powers the apparatus and the apparatus imparts a power demand on the diesel engine, generating a signal of the power demanded of the diesel engine, delivering the signal of the power demanded of the diesel engine to a controller operable to provide output command signals of the power demanded of the diesel engine, supplying air to the combustion chamber of the diesel engine with a supercharger comprising a positive air displacement device having at least one movable member operable to vary the effective displacement of the positive air displacement device such that it varies the trapped air volume generally at the point that the internal air compression of the supercharger begins, operating the supercharger to generate the air supplied to the combustion chamber of the diesel engine, varying the air supplied by the supercharger to the combustion chamber of the diesel engine by operation of the movable member responsive to the command signals from the controller of the power demanded of the diesel engine to selectively boost the flow of air delivered to the combustion chamber of the diesel engine at or above the naturally aspirated flow of air to the combustion chamber of the diesel engine, and introducing combustion fuel into the combustion chamber of the diesel engine responsive to the command signals from the controller corresponding to the boost of the flow of air delivered to the combustion chamber of the diesel engine.
