Purpose The purpose of this study is to get much insight about the combustion and emission characteristics of partially processed high free fatty acid linseed oil, i.e. esterified linseed oil (ELO), and diesel fuel in a single-cylinder compression ignition engine. Design/methodology/approach The variable compression ratio (CR) diesel engine (3.5 kW) of CR ranging from 12:1 to 18:1 is used for the experimentation purpose. In this study, CR varied from 16:1 to 18:1 for investigating the combustion and emissions characteristics of ELO. Various features such as combustion pressure, net heat release rate and mean gas temperature are analysed. The emission characteristics such as hydrocarbon, carbon monoxide, carbon dioxide and nitrogen dioxide are investigated with different loads and CRs. The effect of an ambient temperature condition is also reported. Findings Results from this investigation reveal that the burning of ELO is found to be advanced for all CRs as compared to diesel fuel, whereas these features were found to be lower for a CR of 17. Emissions of ELO are found to be higher at all loads and CRs. Overall, this study provides a necessary framework to enhance further research in this area. Originality/value This investigation shows that ELO has better combustion in the first phase of combustion. However, the exhaust emissions of ELO have higher value due to improper combustion in the second and subsequent phase of combustion due to higher viscosity.

Due to the depleting fossil fuel reserves and increasing environmental concerns, researchers have been studying the effect of adding different types of oils to diesel and more recently plastic oil. The present paper is an experimental study of the effect of compression ratio and injection parameters such as injection pressures and injection timing on the performance and emission characteristics of a variable compression ratio diesel engine fuelled with blends of plastic oil. Various proportions of ethanol and diesel are blended with plastic oils for the preparation of test fuels. It is observed from the experimental study that P90D5E5 blend gives the highest brake thermal efficiency yielding an increase of 16% and 38% compared with pure diesel and pure plastic oil, respectively. Smoke emissions are found to be the lowest for P90D5E5 than diesel and P100. Brake-specific fuel consumption, carbon monoxide and smoke values are reduced for all blends with an increase in injection timing, pressure and compression ratio. Combustion analysis of the blends indicates higher values of cylinder pressures and net heat release rates for P90D5E5 and P100, respectively.
