Purpose: Performances of a tractor diesel engine fueled by three different animal fats biodiesels were evaluated comparing with light oil tractor in terms of power, fuel consumption rate, exhaust gases, particulate matter amount and field work capacity. Methods: Animal fats based on pig biodiesel were manufactured manually and tested for its engine performance in the tractor diesel engine and fuel adoptability in the field works. Four different fuels, three different content of biodiesel (BD20, BD50, BD100) and light oil, were prepared and tested in the four strokes diesel engine. Power output, fuel consumption rate and exhaust gases of the four fuels in the diesel engine were compared and discussed. Results: Power output of light oil engine was the greatest showing 5.3% difference between light oil and BD100, but 0.37% better power than BD20 engine power. Less exhaust gases of $CO_2$, CO, $NO_X$ and THC were produced from animal fats biodiesel than light oil, which confirmed that biodiesel is environmental friendly fuel. For fuel adoptability in the tractor, biodiesel engine tractor showed its fuel competitiveness comparing with light oil for tractor works in the faddy field. Conclusions: With four different fuel types of animal-fats biodiesel, performances of a four cylinder diesel engine for tractor were evaluated in terms of power, exhaust gases, particulate matters (PM) and field work capacity. No significant differences observed in the engine performances including power output and exhaust gases emission rate. No significant power difference observed between the various fuels including light oil on the engine running, however, amounts of noxious exhaust gases including $CO_2$ and $NO_X$ decreased as biodiesel content increased in the fuels. Field performances of animal-fats biodiesel tractor were investigated by conducting plowing and rotary operation in the field. Tilling and rotary performance of light oil tractor and BD20 tractor in the field were compared, in which about 10% travelling speed difference on both operations were monitored that showed light oil tractor was superior to BD20 tractor by 10%. Animal-fats can be an alternative fuel source replacing light oil for agricultural machinery and an environmental friendly fuel to nature.

문제 정의
Animal-fats biodiesel produced in the USA was about 450 million litres in 2008 that was taking up 20% of the total biodiesel production amount in 2008 (Goodfellow, 2010). The objective of this study was to evaluate the performance of tractor disel engine fuelled by animal-fats biodiesel comparing with light oil tractor diesel engine.
제안 방법
In order to measure engine performance with four different fuels we chose C type test cycle, “Off-road vehicles and industrial equipment”, in this experiment.
With four different fuel types of animal-fats biodiesel, performances of a four cylinder diesel engine for tractor were evaluated in terms of power, exhaust gases and temperatures, particulate matters (PM) and field works capacities. No significant differences observed in the engine performances including power output and exhaust gases emission rate.
대상 데이터
A engine used for this investigation is a vertical type water cooled 4 cycle diesel, displacement of 1,999 cm3, power output of 34 kW at 2,600 rpm, manufactured by a domestic tractor company (Table 1).
The tractor mounted with the diesel engine was put on the field works of plowing and rotary operation, the major tractor operations in the faddy plot. Two fuels, BD20 and light oil, were tested for fuel feasibility in the tractor engine. The tractor operater was the same person on the two operations and the two works were carried out by the same condition and the same patten in the one plot, so we assumed that errors of operater and surrounding were ignoable.
However, BD is usually blended with light oil making BD5 or BD20 form, thus calorific value difference is less than 5% in the actual usages. With the 100% pure biodiesel (BD100), four different fuels were prepared for this test; BD20, BD50, BD100 and light oil. BD20 meant biodiesel 20% mixed with light oil 80% in weight basis and BD100% was pure biodiesel BD100% mixed with light oil 0% (Kim et al.
성능/효과
Field performances of animal-fats biodiesel tractor were investigated by conducting plowing and rotary operation in the plot. Tilling and rotary performance of light oil tractor and BD20 tractor in the field were compared, in which about 10% travelling speed difference on both operations were monitored that showed light oil tractor was superior to BD20 tractor by 10%. Animal-fats can be an alternative fuel source replacing light oil for agricultural machinery and an environmental friendly fuel to nature.
