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.

In this research work, a surge tank is developed and utilised in the diesel engine for controlling the NOX emission. This surge tank acts as a damper for fluctuations caused by exhaust gases and also an intercooler in reducing the exhaust gas temperature into the diesel engine intake manifold. With the utilisation of the surge tank, the NOX emission level has been reduced to approximately 50%. The developed surge tank is proved to be effective in maintaining the circulation of water at appropriate temperatures. A trade-off has been established between the engine performance parameters including the brake thermal efficiency, brake specific fuel consumption, exhaust gas temperature and all emission parameters including HC and CO.

The usage of alternate fuels has been a priority ever since the depletion of the conventional fuels. During the recent times the concept of using biodiesel as fuel has been predominant due to its ability to be used in the same engine as conventional fuels. The source of biodiesels are mainly non edible oils such as Jatropha and Pongamia. This paper reviews the properties of the alternate fuels when used in the compression-ignition engine. These alternate fuels used are vegetable oils and alcohols. The review compares the key properties of diesel to the alternate fuels used. The properties such as such as brake thermal efficiency, volumetric efficiency, exhaust gas temperature and smoke levels are compared with the values obtained from the usage of conventional diesel fuel in a low heat rejection engine (L.H.R) engine. apart from the properties there is also a need for the check of pollutants emitted during the processes, oxides of nitrogen from diesel fuel and aldehydes from the alternate fuels.

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.

This paper presents the performance of biodiesel blends in a single-cylinder water-cooled diesel engine. All experiments were carried out at constant speed 1500 rpm and the biodiesel blends were varied from B10 to B100. The engine was equipped with variable compressions ratio (VCR) mechanism. For 100% Jatropha biodiesel, the maximum fuel consumption was 15% higher than that of diesel fuel. The brake thermal efficiency for biodiesel and its blends was found to be slightly higher than that of diesel at various load conditions. The increase in specific fuel consumption ranged from 2.75% to 15% for B10 to B100 fuels. The exhaust gas temperature increased with increased biodiesel blend. The highest exhaust gas temperature observed was 430°C with biodiesel for load conditions 1.5 kW, 2.5 kW, and 3.5 kW, where as for diesel the maximum exhaust gas temperature was 440°C. The CO2emission from the biodiesel fuelled engine was higher by 25% than diesel fuel at full load. The CO emissions were lower with Jatropha by 15%, 13%, and 13% at 1.5 kW, 2.5 kW, and 3.5 kW load conditions, respectively. TheNOxemissions were higher by 16%, 19%, and 20% at 1.5 kW, 2.5 kW, and 3.5 kW than that of the diesel, respectively.

The aim of this experimental work is to study the effect of nanoparticles added to diesel fuel on engine performance characteristic. Nano fuels are prepared by adding Al2O3 or TiO2, both with particle size less than 45nm of diesel fuel. Four doses of each type namely (25, 50, 100 and 150) ppm are prepared. These nanoparticles are blended with diesel fuel in varying volume fraction by the means of an electric mixer and an ultrasonicator. The Nano fuels are (DF+Al2O3) and (DF+TiO2). Physicochemical properties of nano fuels are measured and compared with these of neat diesel. The study shows that the addition of nanoparticles to diesel fuel improves its physical properties such as cetane number, thermal conductivity and viscosity. The influence of nanoparticles addition is very clear on the engine performance. The results show that the performance parameters are improved for example, brake thermal efficiency is increased from 19.4% for diesel to 21% and 25% for DF+Al2O3 and DF+TiO2 respectively, the brake specific fuel consumption (BSFC) is decreased by 8% and 20% for DF+Al2O3 and DF+TiO2 respectively, the brake specific energy consumption (BSFC) is decreased by 8% and 20% for DF+Al2O3 and DF+TiO2 respectively at 25ppm and 75% load. The exhaust gas temperature is 382°C for pure diesel while it is 417°C for DF+Al2O3 and 353°C for DF+TiO2. The peak pressure for pure diesel is 62 bar and it increases with DF+Al2O3 to 66.2 bar as for DF+TiO2 the peak pressure decreases to 57.2 bar at full load and 150ppm.

The effect of iso‐butanol addition to diesel fuel on engine performance parameters has been experimentally investigated. The used engine was a single cylinder four stroke CI engine Type Lister 1–8. The tests were performed at engine speed that ranges from 375 to 625 with an increment of 42 rpm at different loads and with 10, 20, 30 and 40% v/v iso‐butanol‐diesel fuel blends. The overall engine performance parameters measured included air‐fuel ratio (AFR), exhaust gas temperature, brake power (Bp ), brake specific fuel consumption (bsfc) and brake thermal efficiency (η th ). The experimental results show that AFR, exhaust gas temperature, (Bp ) and (ηbth ) decreased and bsfc increased with iso‐butanol addition compared to net diesel fuel. Also, the obtained results indicate that the engine performance parameters when using up to 30% iso‐butanol in fuel blends are better than that of 40%.

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.

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).
