- Paper presents an experimental study on the pressure variations inside of 3 - cylinder, a direct injection AD3.152 type diesel engine. The main aim of the preliminary engine test was to use of the crankshaft free acceleration method for detection of diesel knock phenomenon. For this research, each combustion chamber was equipped with AVL cooled pressure sensor mountedat the top of engine head. Using of such sensors and special prepared at Technical University of Radom data acquisition system allow to record time histories of in-cylinder pressure variations at conditions of free acceleration of the engine crankshaft. Results presented in this paper show, that such transient engine conditions can be successfully used for detection of diesel knock phenomenon. High frequency pressure oscillations, typical for knocking were observed in the first phase of the acceleration process for selected combustion chambers. Experimental tests have been done for engine fuelled with regular diesel oil (DF) and its blend with Ethyl Tert Butyl Ether (ETBE) used as an oxygenated additive. Engine test procedure, used methodology and data acquisition system and engine test results carried out in non-stationary conditions with using of crankshaft acceleration method are presented in the paper.
