Effective utilization and evaluation of waste plastic pyrolysis oil in a low heat rejection single cylinder diesel engine

ABSTRACT

On growing population leads to increasing the energy demand in the automotive sector. Many researchers are working for the substitute alternative for fossil fuel products to meet the huge energy needs. Energy from the waste plastics can be utilized because of its disposal volume increased enormously. The major of the advantage of conversion to fuel is not the only disposal but also enables energy to be derived from the disposal of waste plastics. The motivation of our research is to the utilization of energy retrieval from waste plastics as a Waste Plastic Pyrolysis oil (WPO). The novelty of this research is to evaluate of performance of plastic pyrolysis oil extracted from Low-Density Polyethylene (LDPE) on low heat rejection engine (LHR). The incremental ratio of WPO was blended with pure diesel and its performance and exhaust emission norms are evaluated on a direct injection single cylinder low heat rejection diesel engine. The results of WPO were studied and compared for compatibility with pure diesel. Brake specific fuel consumption decreases for LHRWPO10 about 3 to 8% and the brake thermal efficiency is similar to pure diesel with 23.14% at full load condition. LHRWPO10 evidenced an improved reduction of carbon monoxide ranging from 6 to 14% and hydrocarbon ranging from 7 to 16.2% for various load conditions. LHRWPO20 recorded around 5% reduction in CO at 75% load condition.
