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.

Opis:
This paper explores the feasibility ofusing in-cylinderpressure-based variables in terms of certain class of errors, caused by indirect pressure measurement. Experimental direct in-cylinder measurement pressure setup was constructed, to make comparisons with standard indicator channel and indicator valve design. Zero-dimensional model was used for particular combustion system design. Subsequently, paper describes the application of a zero-dimensional combustion model for pressure signal analysis in cylinder head indicating passage of medium speed marine diesel engine. Recording of engine cylinder pressure development and its qualified evaluation is common aid for maintenance. Especially the outline of experimental test-bed, the injector nozzle equipped with piezoelectric pressure transducer, measurement system specification, B type uncertainty -mean angular speed characteristic, wavelet "denoising" setting and signals comparison, engine cylinder indicator model channel, cylinder pressure traces influenced by engine speed and load, cylinder pressure traces influenced by engine load and speed with two different indicator channel lengths, Indicated engine cylinder power in motoredmode of operation are presented in the paper.
