- The aim of this paper is to study the results obtained from a common rail dual cylinder diesel engine. Modern methodology involves the use of non-intrusive techniques of cylinder pressure measurements using sensors installed in the engine test rig. This work analysis the experiments carried out on a dual cylinder diesel engine .The results obtained are analysed to develop the relationship between the cylinder pressure levels and noise emitted from engine. Multiple injection process in diesel engines; engine test rig setup; cylinder pressure levels, noise levels; PSD plots for cylinder pressure signals, PSD plots for cylinder noise signal, PSD plots for cylinder pressure derivative signals for 1600, 2000 RPM; in cylinder pressure spectrogram at 1600 RPM, 100% load; motored cylinder pressure spectrogram at 1600 RPM; cylinder pressure and noise emission spectrograms; piston slap noise emissions, valve noise emissions and valve noise emissions spectrograms; and correlation between cylinder pressure and radiated noise levels are presented in the paper.
