Abstract

Purpose

This paper aims to present the production of waste plastic oil from landfill waste plastics, the performance and emissions of a compression ignition (CI) engine, using waste plastic oil, were tested and compared with using diesel oil. The physical characteristics, gross calorific value (MJ/kg), kinematic viscosity cst @40°C, specific gravity @15.6°C, cetane index, flash point and distillation temperature @90 per cent are determined. The experimental CI engine is a four-stroke, direct injection, single cylinder, 709 C.C. and has been tested with in-brake-specific fuel consumption (BSFC), brake conversion efficiency, brake-specific energy consumption and exhaust gas emissions.

Design/methodology/approach

The results show that the characteristics of liquid fuel from landfill plastics (LFLP3) are similar to diesel oil. The CI engine was able to run with LFLP3. The efficiency was slightly higher than that of diesel fuel, whereas the BSFC was lower. The exhaust-gas emission average for LFLP3 was reduced compared to diesel oil operation.

Findings

The efficiency of the CI engine using LFLP3 is slightly higher than diesel fuel at all load conditions. In this study, LFLP3 was a lower pollutant than diesel fuel. Environmental values and energy consumption are important when reviewing the ignition of any fuel in a combustion chamber.

Originality/value

The efficiency of the CI engine using LFLP3 is slightly higher than diesel fuel at all load conditions. In this study, LFLP3 was a lower pollutant than diesel fuel. Environmental values and energy consumption are important when reviewing the ignition of any fuel in a combustion chamber.
