combustion pressure measurement - Opis:
- The practical design of the marine engine multi in-cylinder pressure acquisition system has been presented. The system operational properties and measurement methodology is aimed the online marine diesel engine applications. The design of engine combustion pressure recording system is based on piezoelectric sensors set that comprises quartz pressure element and charge amplifier, mounted on the indicator pipes, equipped with valves. The required crank degree signal is obtained from shaft encoder that is installed on the test bed engine shaft-line (free end of the hydraulic break). The encoder's TDC dedicated reference pulse is able generate simultaneously at the cylinder 1 and 6 in TDC position. The accuracy of the static crankshaft position calibration was evaluated. Additionally, a complex timing system was developed for individual cylinder TDC and crankshaft positioning definition. Before real time data acquisition starts, the number of engine cycles is defined for recording and the first pulse of each crankshaft revolution is used as trigger signal, so that all instantaneous pressure and crank angle signals acquisition can be started at the identical crankshaft position. The method provides required numbers of combustion cycles to be measured for time domain averaging and off line processing.
