ABSTRACT:
Heretofore, auxiliary air was directed to a particulate filter assembly of a supercharged diesel engine for proper regeneration thereof by a relatively large auxiliary air compressor, or alternatively from a take-off duct communicating with the inlet manifold of the diesel engine. The former solution often requires a governed compressor for improved efficiency and is expensive, and the latter does not provide satisfactory regeneration throughout the full operating range of the engine. These problems are overcome by providing an oxygen supply system for a diesel engine having an inlet manifold, an exhaust manifold, a supercharger, a first passage device for communicating pressurized air from the supercharger to the inlet manifold, a second passage device including a particulate filter assembly for communicating exhaust gas from the supercharger to the atmosphere, and a third passage device including an auxiliary pump mechanism having a relatively small air pump that provides sufficient oxygen solely from the first passage device to assure proper regeneration under all normal engine operating conditions.
