The method involves deriving an exhaust gas counter pressure from the condition that the quantity of exhaust gas flowing into a volume (20) between at least one exhaust valve (25) of the internal combustion engine (1) and a turbine (5) of the exhaust gas t...

The mass of exhaust gas is determined, in a volume (20) between an engine (1) exhaust valve (25) and a turbine (5) of the exhaust gas turbocharger (5, 10, 15). Pressure after the exhaust valve is determined from the mass of exhaust gas, using the universal...

The invention relates to a method for functional testing of a bypass element (24) that regulates the exhaust gas flow of an internal combustion engine (1) via the exhaust turbine (44) of an exhaust gas turbocharger (40) and a bypass (22) bypassing it, wher...

A system 40 for starting an internal combustion engine 12 of an automotive vehicle 10 has a controller 54 coupled to a starter/alternator 42. The engine 12 has a crankshaft 50 and a turbocharger 24. The controller 54 initiates the starting of the engine 12...
