Abstract: Methods and systems are provided for a diesel fuel injector for an internal combustion engine is provided. The diesel fuel injector comprises an injector nozzle body, the injector nozzle body comprising a first thickness of material, wherein an injection passage for injecting fuel using the fuel injector is formed in the first thickness of material, the injection passage defining an opening through which fuel is sprayed from the injector; and a second thickness of material, wherein the second thickness of material forms an outer surface of the injector nozzle body and wherein the second thickness of material extends around the injection passage, spaced apart from the injection passage opening, such that condensation forming on the outer surface of the injector nozzle body is positioned away from the opening of the injection passage. A method of manufacturing a diesel fuel injector is also provided.

Abstract: A condensate reservoir for a charge air cooler of an engine has one or more inlets for receiving condensate from the charge air cooler, and a chamber for collecting the condensate from the charge air cooler. The condensate reservoir is configured to be in thermal communication with an exhaust gas recirculation duct of the engine such that thermal energy from the exhaust gas recirculation duct may be transferred to the condensate reservoir to vaporize the condensate collected in the chamber.
