Abstract
The present investigation reports the production of pyrolytic plastic oils and their performance in compression ignition (CI) diesel engines with different oil and additive blends. Experimental investigation has been conducted on a four-stroke single-cylinder variable compression diesel engine at a steady engine speed of 1,500 rpm with a different blend of pyrolytic plastic oil (PPO) and ethanol with diesel for various load conditions. Parametric studies are conducted for blend proportion of 10%–20% and compression ratio of 16–18. The engine thermal efficiency is found to be augmented significantly by 2.67% and specific fuel consumption reduced by 0.59% at maximum engine load for 60D20PPO20E to that of diesel. The brake specific fuel consumption is also diminished for fuel mixtures by increase of concentration of additives in the fuel blend than diesel. The overall improvement in engine performance is found at 20% blend of PPO and ethanol in diesel with the highest compression ratio of 18. The novel correlation for brake thermal efficiency with respect to influencing parameters has been developed.
