Natural Sources

Fossil fuel is non-renewable energy. This type of energy sources are widely used in many critical areas such as industrial application and vehicle application. Realizing this fact, many researches are conducted to produce alternative energy sources to reduce the dependence to fossil fuel for energy generation. As for example, fuels that produced from natural sources such as palm, rapeseed and jathropa are commonly used as alternative fuel especially for transportation purpose. Apart from natural sources, waste source such as used tires also can be utilized to produce alternative fuel. In this paper, the engine performance of diesel engine operating with unblended tire derived fuel (TDF) are analyzed and compared to diesel fuel. The experiment is conducted using a single cylinder, direct injection diesel engine. The engine operates at variable engine speed while constant load exerted to the engine. The performance parameters that are analyzed in the experiment includes engine power, engine torque, combustion pressure and exhaust gas temperature. Results from the experiment shows that diesel engine can operate with unblended TDF. However, TDF is not suitable for high engine speed applications. Furthermore, TDF produce lower performance output compared to diesel fuel.

This paper investigates the impacts of using n-butanol-diesel fuel and ethanol-diesel fuel blends on engine performance, exhaust emission, and cycle-by-cycle variation in a Diesel engine. The engine was operated at two different engine speed and full load condition with pure diesel fuel, 5% and 10% (by vol.) ethanol and n-butanol fuel blends. The coefficient of variation of indicated mean effective pressure was used to evaluate the cyclic variability of n-butanol-diesel fuel and ethanol-diesel fuel blends. The results obtained in this study showed that effective efficiency and brake specific fuel consumption generally increased with the use of the n-butanol-diesel fuel or ethanol-diesel fuel blends with respect to that of the neat diesel fuel. The addition of ethanol or n-butanol to diesel fuel caused a decrement in CO and NOx emissions. Also, the results indicated that cycle-by-cycle variation has an increasing trend with the increase of alcohol-diesel blending ratio for all engine speed. An increase in cyclic variability of alcohol-diesel fuel blends at low engine speed is higher than that of high engine speed.

The consumption of diesel fuel in Indonesia is increasing every year, one way to overcome this problem is to use natural bioaditive in the form of essential oils found in Indonesia. Essential oils used in this study are fragrant lemongrass because fragrant lemongrass contains carboxylic compounds (-COOH) [1,2,3]. With the aim of improving engine performance and reducing fuel consumption. This research was conducted by mixing fragrant citronella oil with diesel oil with a percentage of 1%, 0.5% and 0.1% of the total volume. Diesel engines are operated with variations in loading 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800 and 2000 W at a constant engine speed of 1500 rpm. The variables measured and calculated in this experiment are power, torque, Break Mean Effective Pressure (BMEP), Specific Fuel Consumption (SFC). The results showed that adding citronella oil to diesel fuel with a percentage of 1%, 0.5% and 0.1% significantly reduced fuel consumption by 15.5%, 3.6% and 2.6% respectively. The maximum reduction in fuel consumption reaches 0.055 liters / hour at 200W loading with a bioaditive level of 0.1%. The next study planned is to mix clove oil and citronella oil as bioaditive so that it is expected to reduce fuel consumption and engine corrosion.

Waste Plastic

The increase of industrial activities and motor vehicles globally causes rise demands in fossil fuel as energy sources. Since fossil fuel is non-renewable energy, many researches have been conducted to reduce the reliance to this fossil fuel. In conjunction, the number of waste plastic and tires around the world is increasing as a result of modern application and increasing number of motor vehicle. This type of waste is hard to decays and commonly dumped onto open landfills. Utilization of waste tires and plastics can produce alternative fuel that potentially can be used in diesel engine. In this paper, the combustion characteristics of two waste source fuels known as waste plastic disposal fuel (WPDF) and tire disposal fuel (TDF) are discussed. The combustion characteristics of both fuels are compared to diesel fuel. WPDF and TDF used in this experiment are pure concentrated and not blended with diesel fuel. The experiment is conducted using single cylinder YANMAR TF120M diesel engine. The engine is operated at constant load at 20 Nm and variable speed ranged from 1200 rpm to 2400 rpm. The combustion characteristics that discussed in this paper are ignition delay and peak pressure. Both characteristic are measured at two engine speed region which is low speed (1200 rpm) and high speed (2100 rpm). From the results obtained, it can be observed that WPDF has comparable ignition delay compared to diesel fuel while TDF has longest ignition delay compared to WPDF and diesel fuel. TDF also produce highest peak pressure compared to other tested fuels. Moreover, TDF is not suitable for high speed application since it cause backfire when engine speed reach 2200 rpm.

Experimental testing using coconut oil produced by dry method on engine has been conducted in the Laboratory of Energy Conversion, Mechanical Engineering, Mataram University. The purpose was to evaluate the effect of using this coconut oil on the engine performance. The oil was mixed with diesel oil in order to obtain biodiesel. There were four combinations of ratio diesel oil to coconut oil; namely 100% : 0% (mkp0%), 90%:10% (mkp10%), 80%:20% (mkp20%) and 70%:30% (mkp30%.). Mitsubishi L300 diesel engine was used in this experiment by variating engine speed 1000 rpm, 1050 rpm and 1100 rpm with torgue load at 1 kg. At engine speed of 1200 rpm the loads were varied as 1 kg, 1.5 kg and 2 kg. The result shows that by increasing the number of coconut oil in the mixture will reduce engine fuel consumption. Fuel consumption of the mixture will be better compare to the fuel consumption of pure diesel oil. Specific fuel consumption efective (SFCe) of coconut oil-diesel mixture at mkp 10%, 20% and 30% are lower than of pure diesel oil. The reduced SFCe are 1.45 %, 1.71% and 3.57 % at effective power 0.838 PS, 1.98%, 4.31% and 4.31% at effective power 1.257 PS and 1.22%, 3.92% and 7.12% at effective power 1.676 PS. By varying the engine speed, the result also shows that SFCe of the mixture is also lower than SFCe of pure diesel oil.

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.
