The method uses an additional charge from the exhaust system (7) in a low RPM range, so that the exhaust valve (6) is opened at the beginning of a compression stroke. After the valve is closed, the exhaust gas fed into the combustion chamber is used to compress the chamber volume via the piston (2). At the end of the compression stroke, the exhaust valve is opened and the exhaust gas is blown out of the chamber via the exhaust valve into the exhaust system. Opening timing and opening duration of the exhaust valve are continuously regulated dependant upon exhaust temperature and engine RPM. |
