VERFAHREN ZUR AUSWERTUNG DES BRENNRAUMDRUCKVERLAUFS
摘要:
The invention relates to a method for evaluating the march of pressure in the combustion chamber of an internal combustion engine, wherein the output signal of at least one cylinder pressure sensor and a crankshaft angle sensor is evaluated. Pressure march characteristics for specific valve control times are obtained by analysing the march of pressure in the combustion chamber via the crankshaft angle. Said characteristics enable the following valve control times to be deduced in relation to the crankshaft angle: 'outlet opens', 'outlet closes', 'inlet opens', 'inlet closes'.
