Abstract
A compact system for introducing hydrocarbons in the form of engine fuel into the bearing housing for a turbocharger adjacent the turbine wheel shaft. The hydrocarbons are directed outward by centrifugal force and are vaporized by the heat of the impeller. As a result the hydrocarbons are available substantially immediately after the turbine to interact with a catalyst to increase the temperature of the exhaust stream for regeneration of a diesel particulate filter.
