The depletion of fossil fuels as well as the rises of greenhouse gases had caused most government worldwide to follow the international energy policies for the use of biodiesel. One of the economical sources for biodiesel production is waste cooking oil. The use of waste cooking oil is more sustainable if they can perform similarly to conventional diesel fuel. This paper deals with the experimental study carried out to evaluate the engine performance and exhaust emission of diesel engine operated by biodiesel from waste cooking oil at various engine speed. The biodiesel used are known as B5, which contains of 5% of waste cooking oil and 95% of diesel fuel. The other one is B20, which contains of 20% of waste cooking oil plus 80% of diesel. Diesel was used as a comparison purposes. The results show that power and torque for B5 give the closest trend to diesel. In terms of heat release, diesel still dominates the highest value compared to B5 and B20. For exhaust emission, B5 and B20 showed improvement in the reduction of NOx and PM.

Particulate matter (PM) is one of the major pollutants emitted by diesel engine which have adverse effects on human health. Accordingly, many researches have been done to find alternative fuels that are clean and efficient. Biodiesel is preferred as an alternative source for diesel engine which produces lower PM than diesel fuel. However, the manufacturing cost of biodiesel from vegetable oil is expensive. Therefore, using waste cooking oil (WCO) for biodiesel would be more economical and sustainable solution. The characteristics of direct injection diesel engine in term of the PM have been investigated experimentally in this study. The experiments were conducted using single cylinder diesel engine with different speed (1200 rpm, 1500 rpm, 1800 rpm, 2100 rpm, 2400 rpm) at constant load. PM emission of WCO B100 and diesel fuel was compared and the effect of PM components such as soluble organic fraction (SOF) and soot were studied. The result showed WCO B100 reduces the PM emission at all engine speed. Furthermore, both fuels showed highest reduction of PM concentration at moderate engine speed of 1500 rpm.

Nowadays, many researches are conducted to produce alternative fuel. In order to overcome increasing price of fossil fuel and environmental issues, fuel from natural sources such as palm, rapeseed and jathropa are increasingly being utilized to produce bio-fuel. Similar as natural source, waste product such as plastics and tires also can be processed to produce alternative fuel. In this paper, engine performance of diesel engine operating with 100% waste plastic disposal fuel (WPDF) is analyzed and compared to diesel fuel. The experiment is conducted using single cylinder YANMAR TF120M diesel engine which is operating at variable speed and constant load. The performance parameters that analyzed in the experiment are engine power, torque, combustion pressure and exhaust gas temperature. Results of the experiment shows that waste plastic disposal fuel (WPDF) potentially can be use as alternative fuel in diesel engine. However, based on the data obtained, performance of diesel engine operating with WPDF is lower compared to diesel fuel.

Cooking Oil

In the present experimental investigation, untreated waste cooking oil (UWCO) was used as an alternative fuel for a diesel engine. The high viscosity of the UWCO was reduced by blending with ordinary diesel. The blends of varying proportions of UWCO and diesel were prepared, analyzed and compared with diesel fuel. Measurements of chemical and physical properties have indicated a good potential of using UWCO as an alternative diesel engine fuel. The results showed that blends containing 5 to 40% of UWCO in diesel yielded the properties closely matching that of diesel. The performance of the engine using blends of UWCO was evaluated in a four cylinder diesel engine and compared with the performance obtained with diesel. Significant improvement in the engine performance was observed. The results showed that the addition of 30% UWCO with diesel produced higher brake power with a reduction in exhaust emission such as CO2 and NOx. The specific fuel consumption and the exhaust temperature were increased due to decrease in viscosity of the UWCO. Acceptable thermal efficiencies of the engine were obtained with blends containing up to 30% volume of UWCO. From the properties and engine test result, it has been established that 10-30% of UWCO can be substituted for diesel without any engine modification.

The increasing consumption and demand for fossil fuels have more significance than before alarm above its lessening rate and for that reason, stimulated the actions are needed to challenge the issue with an efficient and less polluting alternative fuel for diesel. This study evaluated the performance of an 8.2 kW small diesel engine using three fuels, namely diesel, waste cooking oil biodiesel and wild tree biodiesel, such as granadilla oil biodiesel (GBD) and tung oil biodiesel (TBD). The experimental engine was tested at 1,500 rpm of constant engine speed and 20–80% of engine load. The specific fuel consumption, brake specific energy consumption, brake mean sufficient pressure, brake thermal efficiency, exhaust emission and temperature were evaluated. It was found that the small diesel engine worked well using wild trees biodiesel. The brake means effective pressures were lower by 5–8% and thermal brake efficiency was decreased in the range of 9–15%, compared with diesel fuel. The exhaust emission was lower than Thailand’s industrial standard and slightly higher than waste cooking oil biodiesel and diesel fuel operation. The operation of biodiesel from wild trees is suitable for farmers and is considered feasible for local communities in the future.

In this study, engine performance on thermal factors for different biodiesels has been studied and compared with diesel fuel. Biodiesels were produced from Pongamia pinnata (PP), Calophyllum inophyllum (CI), waste cooking oil (WCO), and acid oil. Depending on their free fatty acid content, they were subjected to the transesterification process to produce biodiesel. The main characterizations of density, calorific range, cloud, pour, flash and fire point followed by the viscosity of obtained biodiesels were conducted and compared with mineral diesel. The characterization results presented benefits near to standard diesel fuel. Then the proposed diesel engine was analyzed using four blends of higher concentrations of B50, B65, B80, and B100 to better substitute fuel for mineral diesel. For each blend, different biodiesels were compared, and the relative best performance of the biodiesel is concluded. This diesel engine was tested in terms of BSFC (brake-specific fuel consumption), BTE (brake thermal efficiency), and EGT (exhaust gas temperature) calculated with the obtained results. The B50 blend of acid oil provided the highest BTE compared to other biodiesels at all loads while B50 blend of WCO provided the lowest BSFC compared to other biodiesels, and B50 blends of all biodiesels provided a minimum % of the increase in EGT compared to diesel.

Global Agenda

The continued using of petroleum energy as a sourced for fuel is widely recognized as unsustainable because of the decreasing of supplies while increasing of the demand. Therefore, it becomes a global agenda to develop a renewable, sustainable and alternative fuel to meets with all the demand. Thus, biodiesel seems to be one of the best choices. In Malaysia, the biodiesel used is from edible vegetable oil sources; palm oil. The uses of palm oil as biodiesel production source have been concern because of the competition with food materials. In this study, various types of biodiesel feedstock are being studied and compared with diesel. The purpose of this comparison is to obtain the optimum engine performance of these different types of biodiesel (edible, non-edible, waste cooking oil) on which are more suitable to be used as alternative fuel. The optimum engine performance effect can be obtains by considering the Brake Power (BP), Specific Fuel Consumption (SFC), Exhaust Gas Temperature (EGT) and Brake Thermal Efficiency (BTE).

Performance And Emission

This paper presents a comparative analysis of the diesel engine performance and emission characteristics, when operating on diesel fuel and various diesel-biodiesel (B10, B20, B40, B60) blends, at various loads and engine speeds. The experimental tests were performed on a four-stroke, four-cylinder, direct injection, naturally aspirated, 60 kW diesel engine D-243. The in-cylinder pressure data was analysed to determine the ignition delay, the Heat Release Rate (HRR), maximum in-cylinder pressure and maximum pressure gradients. The influence of diesel-biodiesel blends on the Brake Specific Fuel Consumption (bsfc) and exhaust emissions was also investigated. The bench test results showed that when the engine running on blends B60 at full engine load and rated speed, the autoignition delay was 13.5% longer, in comparison with mineral diesel. Maximum cylinder pressure decreased about 1–2% when the amount of Rapeseed Methyl Ester (RME) expanded in the diesel fuel when operating at full load and 1400 min–1 speed. At rated mode, the minimum bsfc increased, when operating on biofuel blends compared to mineral diesel. The maximum brake thermal efficiency sustained at the levels from 0.3% to 6.5% lower in comparison with mineral diesel operating at full (100%) load. When the engine was running at maximum torque mode using diesel – RME fuel blends B10, B20, B40 and B60 the total emissions of nitrogen oxides decreased. At full and moderate load, the emission of carbon monoxide significantly raised as the amount of RME in fuel increased.
