EN It is important that marine diesel engines run in their normal condition in order to maintain correct efficiency, low pollution and high reliability. The record of in-cylinder pressure pattern and its evaluation is one of the most powerful sources for experimental based analysis of internal combustion engines. In addition, collected data and calculated values expand the engine diagnostic system capabilities. From the other hand reliable calculation of mean indicated pressure and other performance data requires accurate measurement of cylinder pressures and detection of the crankshaft position. It is necessary to ensure correct synchronization of recorded pressure shape with crankshaft position. For this purpose magnetic pick-up to measure the rotational speed from flywheel is usually used as a source of sampling pulses. The instantaneous piston speed can be investigated using the linear movement sensor located inside the crankshaft box. For this purpose marine propulsion testing engine was equipped with optic fiber sensor to perform permanent piston position measurement. Test bed with examined engine is equipped additionally with: optoelectronic in-cylinder pressure transducer, magnetic pick-up to measure rotational speed from flywheel, optic fiber sensor to measure the rotational speed and angular increments from propeller shaft and strain gauge arrangement designed to provide effective torque measurement.
