Embodiment Construction

[0033] The following description of this or these embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application or uses.

[0034] see now Figure 2A , one embodiment of the present invention includes a product or system 10 that may include one or more of the following components. System 10 may include an internal combustion engine 12 such as, but not limited to, a diesel internal combustion engine. The intake side 14 may include an intake manifold 18 coupled to the internal combustion engine 12 to deliver air into cylinders of the internal combustion engine 12 . A main intake line 20 may be provided and connected at one end 22 to (or form part of) the intake manifold 18 and may include an open end 24 for drawing air therethrough. An air filter 26 may be located at or near the open end 24 of the main intake line 20 .

[0035] A combustion gas exhaust side 16 may be provided and constructed and arranged to exhaust combustion exhaus...

Abstract

One embodiment of the invention includes a method comprising: in an internal combustion engine ventilation system having an intake side and a combustion exhaust side, injecting air from the intake side into the combustion gas exhaust side.

Description

[0001] This application claims the benefit of US Provisional Application Serial No. 60 / 886,921, filed January 27, 2007. technical field [0002] The field to which this disclosure generally relates includes internal combustion engine ventilation systems and components thereof, turbocharger systems and components, and methods of making and using the same. Background technique [0003] Figure 1 is a schematic diagram of a product or system 10 including a modern gas exchange system for a single-stage turbocharger. Such a system may include an internal combustion engine 12 constructed and arranged to burn a fuel, such as diesel fuel, in the presence of oxygen (air). System 10 may further include a ventilation system including an intake side 14 and a combustion gas exhaust side 16 . The intake side may include an intake manifold 18 coupled to the internal combustion engine 12 to deliver air into cylinders of the internal combustion engine 12 . A main intake line 20 may be provi...
