Singh, Ishmeet (2017) Impact of using waste cooking oil (WCO) and kerosene (K) blend as renewable additive to diesel fuel on diesel engine performance and emissions. Coursework Masters thesis, University of Southern Queensland. (Unpublished)
Abstract
The exhaust emissions of the engines has impacted the environment and the human health by leading to global warming and severe health conditions. The elevated demand of fossil fuels has increased the crude oil prices and the fuel reserves are expected to exhaust in the near future. The above factors has led to a push towards the research and production of alternative renewable fuels which may serve as supplement to the current fossil fuels.
In this project, the performance and emissions of a four stroke single cylinder air – cooled Yanmar diesel engine were studied with two different fuels: Waste Cooking Oil (WCO) – Kerosene Oil (K) – Petroleum Diesel (PD) blend and ordinary Petroleum Diesel. The Waste Cooking Oil was blended with Kerosene Oil in a 10:10 proportion by volume and added to Petroleum Diesel (80%) without the transesterification process. The fuels properties of the fuel and the different blends were recorded. The performance and the emissions were compared for WCO (10%)-K (10%) - PD (80%) blend to that of Petroleum Diesel at different engine speeds. The performance was compared in terms of brake power, torque, brake specific fuel consumption, brake thermal efficiency and exhaust gas temperature and the emissions of Carbon Monoxide (CO), Carbon Dioxide (CO2), Nitrogen Oxides (NOx) and unburned Hydrocarbon (HC) were analysed for both the fuels.
The brake power and torque for the Waste Cooking Oil – Kerosene – Diesel (WCO10K10D80) fuel blend was higher than that achieved by the neat Petroleum Diesel (D100). A maximum brake power of 2.37 kW was achieved using the WCO10K10D80 fuel blend whereas the peak power achieved by the Petroleum Diesel was 2.05 kW. The maximum torque achieved using the WCO10K10D80 fuel blend was 7.85 N.m and the maximum for D100 was 7.03 N.m. The brake specific fuel consumption for the v WCO10K10D80 fuel blend was less than the D100 fuel. The exhaust gas temperature was lower for the WCO10K10D80 fuel blend than the D100 fuel. The brake thermal efficiency was improved with the WCO10K10D80 fuel blend which attained a maximum of 18.11 % at 2850 rpm. With the WCO10K10D80 fuel blends the NOx and CO2 emissions were lower than that of with the Petroleum Diesel. The CO and the unburned hydrocarbons for WCO10K10D80 blend showed higher levels as compared to the Petroleum Diesel. Oxygen emission showed a similar trend for both the fuel blends.
