Plastic waste can be converted into oil and used as alternative fuel. Increasing the intake density can solve the problem of high emissions during engine operation. The tri-charged technology avoids turbo lag, power consumption, and reduction in emissions. The results showed good performance of the tri-charged engine running on pyrolysis oil.
Plastic waste is an absolute source of energy due to its high heating value and economy. It can be converted into oil by pyrolysis process and used in internal combustion engines as an alternative fuel. However, it emits significant-high emissions, challenging to operate the engine in a continuous regime. These problems can be resolved by increasing the intake density. The supercharger and turbocharger are the best options to increase the density of intake air. However, the turbocharger has a problem of turbo lag, and the supercharger consumes engine output. Thus, in the present work, a tri-charged technology is implemented to avoid the problem of turbo-lag, power consumption, and reduction in emissions when operates at different blends of pyrolysis oil. Results showed that the tri-charged engine could run on plastic waste pyrolysis oil operate at full load capacity, presenting good performance compared with the conventional diesel engine. The best engine performance was found at PPO-20 in combination with tricharged boosting. However, more percentage blending tends to increase the HC and CO emissions, with a fuel efficiency penalty. The result suggested that tri-charged technology is a promising technology and pyrolysis oil is an alternative fuel for specific engine applications at certain operating conditions.(c) 2022 Elsevier Ltd.
