A turbocharged, diesel engine has a small catalyst provided upstream of the turbocharger with EGR collected from the exhaust stream downstream of the catalyst and upstream of the turbocharger. By making the catalyst small, it packages into a pipe coupling the manifold to the turbocharger, readily reaches lightoff, and absorbs little exhaust energy, thereby providing acceptable conversion of hydrocarbons and CO, but still allowing fast turbocharger response. In one embodiment, the engine has two cylinder banks, two exhaust manifolds, and two pre-turbo catalysts installed upstream of the turbine.

A turbocharger system for an internal combustion engine includes a turbocharger with a utility pedestal extending between the turbocharger and hard point associated with the cylinder block. The utility pedestal includes a mounting pad for attaching the combined turbocharger and pedestal assembly to an engine, as well as internal oil and coolant supply passages for supplying the turbocharger with coolant and lubricating oil under pressure.

A turbocharger system for an internal combustion engine includes a turbocharger with a utility pedestal extending between the turbocharger and the hard point associated with the cylinder block. The utility pedestal includes a mounting pad for attaching the combined turbocharger and pedestal assembly to an engine, as well as oil and coolant supply passages for supplying the turbocharger with coolant and lubricating oil under pressure. An internal, isolated, turbocharger oil drainback passage conducts waste oil from the turbocharger to a crankcase sump without permitting the waste oil to contact the engine's moving parts.

A turbocharger system for an internal combustion engine includes a turbocharger with a utility pedestal extending between the turbocharger and a mounting surface associated with the engine. The utility pedestal includes a mounting pad for attaching the combined turbocharger and pedestal assembly to the engine, as well as internal oil and coolant supply passages for supplying the turbocharger with coolant and lubricating oil under pressure.

A turbocharger system for an internal combustion engine includes a turbocharger with a utility pedestal extending between the turbocharger and a mounting point associated with the cylinder block. The utility pedestal includes a mounting pad for attaching the combined turbocharger and pedestal assembly to an engine, as well as oil and coolant supply passages for supplying the turbocharger with coolant and lubricating oil under pressure. The utility pedestal's fastening system is configured so as to cover a minimum amount of space of the engine surface to which the pedestal is mounted, so as to reduce the footprint of the turbocharger system.

A dual-inlet turbocharger system for internal combustion engine includes a single-shaft turbocharger with a dual-inlet compressor section. An air router provides a bifurcated air supply for the dual-inlet compressor section, and also provides a bifurcated source of charge air for the engine's cylinders in the case in which the present turbocharger system is applied to a V-block engine.

As one example, an apparatus configured to regulate flow in an exhaust passage of an internal combustion engine system is provided. The apparatus comprise a housing disposed within the exhaust passage defining a first region and a second region, where the first region includes a first stopper and a first valve plate, where first stopper completely surrounds first region, and the first valve plate seats on the first stopper to seal first region, and where the second region includes a second stopper and second valve plate, where second stopper completely surrounds the second region, and the second valve plate seats on the second stopper to seal second region, and where the first stopper; a translating mechanism coupled between first and second plates, the mechanism coupling the first and second plates through a set of gears in the housing, such that forces acting to close first plate are translated through mechanism to act to open the second plate, and vice versa; and an actuator to move the translating mechanism, where such movement causes both the first and second plates to rotate concurrently.
