Controlling turbocharger boost pressure using exhaust pressure estimated from engine cylinder pressure.

Turbocharger boost control using exhaust pressure estimated from engine cylinder pressure

One exemplary embodiment includes a product including a housing that has a mixer portion and first, second and third openings. The first opening is configured to receive at least a portion of exhaust gases produced by an internal combustion engine, and the second opening is configured to receive intake air. The mixer portion is in communication with the first and second openings to mix the exhaust gases and the intake air into a gas mixture. The third opening is in communication with the mixer portion to flow the gas mixture therethrough. The invention further includes a particulate separator disposed within the housing. The particulate separator is configured to remove particulates from the exhaust gases. The product may be included in a low-pressure EGR path and/or a high-pressure EGR path.

The present invention relates to a compressor-cooler module, having a housing, a compressor contained in the housing, and an air cooler disposed within the housing and positioned in the flow path of the compressor. The present invention also includes an intake in fluid communication with the housing, a cooler bypass valve operably associated with the air cooler and the compressor, and a low-pressure exhaust gas recirculation passage operably associated with the cooler bypass valve, and the cooler bypass valve selectively directs exhaust gas to bypass the air cooler.

Integration of an exhaust air cooler into a turbocharger

An adsorption element for adsorbing gases and vapors from the gaseous atmosphere in the intake tract of an internal combustion engine. The adsorption element is disposed within a wall of a flow cross section carrying the intake air, has a planar adsorption medium along which the intake air flows, and is pleated to create folds in longitudinal direction of the intake stream.
