Prices of fossil fuels are heightening day by day. Stringent emission norms, escalation in energy demand and depletion of traditional fuels, forced the researchers to find alternative for internal combustion engines. On the other hand utilization of plastic products in various fields has tremendously increased and globally it has contributed a lot for economic growth, but its indispensable nature confronting viable environment. Presence of hydrocarbons in waste plastic products grabs the attention of researchers in recycling and converting them into liquid fuel. Properties of oil derived from waste plastics are close to that of conventional fuels used in internal combustion engines. This experimental study attempts to investigate the performance emissions and combustion characterises of common rail direct injection (CRDI) engine fuelled with waste plastic oil and diesel blends. The experiments are carried out with 10, 20 and 30% of diesel blended with waste plastic oil on volume basis. The investigations are carried out at a constant speed of 2000 rpm with load varying from 20 to 80%. Results illustrate that 9.23 % decrement of brake thermal efficiency and increment of 16.35% in NOx emissions are perceived when contrasted with diesel.
