In this study is investigated the possibility of removal of the barred speed range by reducing only one harmonic component of the excitation, that one responsible for resonance within the barred speed range. The active torsional vibrations control was based on a pilot injection and delayed combustion while keeping mean indicated pressure (m.i.p.) at the required value for a normal operation of the marine engine on the propeller law. The Sulzer two

A new thermal recycling system for the production of alternative fuel from waste plastics is developed, in which plastic waste is melted and mixed with heavy oil A at temperatures around 200 °C, producing fuels that are suitable for diesel engine generator systems. In experiments, polyethylene (PE), polypropylene (PP), and polystyrene (PS) of weight-average molecular weights (Mw) between 4,000 to 300,000 were used in the production of polymer fuel
