Abstract: An internal combustion engine includes an intake manifold supplying charge air to the cylinders. An exhaust manifold conducts exhaust gas away from the cylinders. A turbocharger including a turbine has an exhaust gas inlet connected with the exhaust manifold and also includes a compressor having an air inlet and outlet. The compressor air outlet is connected to the intake manifold to pressurize charge air during high power levels of engine operation. An EGR bypass connected between the turbine exhaust gas inlet and the intake manifold recirculates a portion of the exhaust gases to the cylinders. An intake air bypass adapted to recirculate a portion of compressor outlet air back to the compressor air inlet to reduce compressor outlet pressure and aid EGR flow through the EGR bypass to the cylinders during high power operation of the engine is connected between the compressor air outlet and the compressor air inlet.

Abstract: A turbocharger component cooling system employs an ejector using energizing gas from the turbocharger system to draw cooling fluid through a plenum around the component to be cooled into the secondary inlet of the ejector and dumping the combined energizing and cooling gas flows into a low pressure dump. Energizing gas is drawn from the high pressure side of the compressor or turbine flows in the turbocharger and returned to the low pressure side in the same flow.

Abstract: An airflow system for an engine includes a first turbine coupled with a first compressor and a second turbine coupled with a second compressor. The first turbine receives exhaust from the engine, and the first compressor supplies compressed air to the engine. The second compressor compresses air from atmosphere. A first conduit fluidly couples the first and second turbines, and a second conduit fluidly couples the first and second compressors. A wastegate valve is fluidly coupled with the exhaust manifold and movable between a first position in which exhaust fluid is allowed to bypass the first turbine and a second position in which fluid is restricted from bypassing. The airflow system includes a third conduit fluidly coupling the second compressor and the wastegate valve. The wastegate valve moves to the first position when compressed air in the third conduit has at least a predetermined pressure.

Abstract: A method of operating an internal combustion engine wherein intake ambient air is boosted to a higher pressure by passage through at least one compressor and then introduced into the internal combustion engine. Fuel is also introduced into the internal combustion engine for providing combustion in admixture with the air charge at a combustion temperature approximating a target value. Various engine operating parameters, inclusive of torque demand, e.g., accelerator pedal depression, are sensed and the boosted pressure is changed in a manner proportional to a change in the sensed torque demand so as to maintain the combustion temperature at approximately the target value, i.e., below 2100° K.

Abstract: A system and method for determining EGR flow in a multi-cylinder internal combustion engine include determining specific heat of the exhaust gas based on current engine operating conditions and determining EGR flow rate based on the determined specific heat and a signal provided by a sensor. In one embodiment, a species tracking model is used to determine the amount of various species within the exhaust gas which may include oxygen, nitrogen, carbon dioxide, and water, for example, to determine the current specific heat, which is compared to a reference specific heat for the sensor, the difference being used to adjust the sensor value and determine the EGR mass flow rate. The species tracking model uses a simplified combustion model to estimate the amount of each specie in the exhaust gas based on various engine operating parameters, such as fuel, air/fuel ratio, and turbo boost, for example.

Abstract: In a method of limiting the charge pressure of an internal combustion engine charged using an exhaust gas turbocharger, a control unit performs an actual value/setpoint value comparison of a controlled variable with a predefined limit value and generates or limits actuating signals for an actuator drive of an actuator acting upon the controlled variable. The setpoint value is taken from a characteristic map memory as a function of the instantaneous operating state of the internal combustion engine. In order to allow the internal combustion engine to operate at the highest possible charge pressure and corresponding power output, measured values of the temperature and of the pressure upstream and downstream, respectively, from a compressor of the exhaust gas turbocharger are used for reading the limit value from the characteristic map memory.
