US 2009/0241541 A1 · PRE-TURBO EXAHUST FILTRATION SYSTEM FOR INTERNAL COMBUSTION ENGINES

Abstract

An air induction and exhaust system for a diesel engine provides particulate filtering upstream from a turbocharger assembly in the exhaust system. The air induction system provides for compression of the charge air, with an induction compressor 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 which is located in the exhaust system in close proximity to an engine exhaust manifold and upstream from the exhaust impeller of the turbocharger. With the diesel particulate filter so located exhaust heat helps initiate carbon oxidation in the filter, and heat generated by oxidation in the filter contributes to turbocharger operation.

Dependent claims

A motor vehicle comprising:

an air induction system;
an exhaust system;
an engine compartment;
an engine located in the engine compartment and connected to receive charge air from the air induction system to support internal combustion and further connected to discharge exhaust gas resulting from internal combustion to the exhaust system;
a particulate filter connected into the exhaust system downstream from the engine;
and
a turbocharger having an exhaust turbine remotely mounted to the vehicle relative to the engine compartment and in the exhaust system downstream from the particulate filter and further having a compressor driven by the exhaust turbine for pumping air into the air induction system, the compressor also being remotely mounted relative the engine compartment.
