Abstract

An exhaust gas turbocharging system for an internal combustion engine including a turbine portion with adjustable turbine geometry for powering a compressor portion which delivers a pressurized charge air mass flow to the internal combustion engine air intake. A charge regulator controls the turbine geometry so that the cross-section of exhaust gas flow to the turbine portion is decreased with an increased working load of the internal combustion engine. It is further proposed that at least one heat exchanger is exposed to the charge air circuit so that heated air is fed thereto for heating such as to heat engine lubricating oil.
