    摘要: An air induction and exhaust system for a diesel engine provides particulate filtering upstream from a turbocharger assembly (116) in the exhaust system. The air induction system provides for compression of the charge air, with an induction compressor (419) being part of a turbocharger system. The exhaust and induction impellers are located outside of a vehicle engine compartment to aid thermal management. The exhaust system provides a diesel particulate filter (32) which is located in the exhaust system in close proximity to an engine exhaust manifold and upstream from the exhaust impeller (417) of the turbocharger. With the diesel particulate filter (32) so located exhaust heat helps initiate carbon oxidation in the filter (32), and heat generated by oxidation in the filter (32) contributes to turbocharger (116) operation.
