“…This test was developed to simulate wear in hydraulic pump components and correlated well with both pump stand and vehicle field tests. All these laboratory tests basically have been conducted in order to simulate the wear in engine parts that are in contact with biodiesel (Fazal,et al;23) Kimberly, et al, 24) ). The tribology wear tests used the ball-on-ring contact method with four different fuels forcing a stationary ball against a rotating ring, forming the tribocontact (Fig.…”

Lubricity is a critical property of diesel fuel because it affects engine performance. Current and future regulations are expected to reduce the sulfur content of diesel fuel. Low lubricity (i.e., low sulfur content) increases diesel engine wear and damages the fuel injection system. Alternative types of fuel have reduced diesel engine exhaust emissions and improved the friction and wear properties of engine parts.Four types of diesel fuel, pure petrodiesel, soybean oil, palm oil, and waste edible oil (WEO), were compared for their fuel properties, engine performance, and emission characteristics. A series of tests was performed using various types of diesel fuel. The ball-on-ring wear testing method was used as an analytical tool for this purpose. The lubricating efficiency of the fuels was estimated using a photomicroscope to measure the average width of the wear scar produced on the test ring.The wear experiments showed that the wear scar widths were 3.48 mm, 2.76 mm, 2.90 mm, and 2.93 mm for lubrication of the pure petrodiesel, soybean oil, palm oil, and WEO, respectively. Lubricities of this diesel are as follows: soybean oil > palm oil > WEO > pure petrodiesel. The ability of biodiesel to be highly biodegradable and its superior lubricating property when used in compression ignition engines make it an excellent fuel. This detailed experimental investigation confirms that biodiesel can substitute mineral diesel without any modification in the engine. The use of biofuels as diesel engine fuels can play a vital role in helping the developed and developing countries to reduce the environmental impact of fossil fuels.

“…Habibullah et al [21] found that 20% calophyllum biodiesel blends have a better lubrication performance than diesel and other blends at different loads (40 kg, 50 kg, 63 kg and 80 kg) at a constant speed (1800 rpm) and room temperature using a four-ball tribotester. Each biodiesel fuel showed lower friction and wear characteristics than low sulfur fuels [22]. The lubrication performance of jatropha biodiesel blends increases with increasing the percentages of biodiesel in the blend, and the jatropha biodiesel showed better lubricity at lower load and temperature conditions [23].…”

Study on the Tribological Characteristics of Australian Native First Generation and Second Generation Biodiesel Fuel

Biodiesels are a renewable energy source, and they have the potential to be used as alternatives to diesel fuel. The aim of this study is to investigate the wear and friction characteristics of Australian native first generation and second generation biodiesels using a four-ball tribo tester. The biodiesel was produced through a two-step transesterification process and characterized according to the American Society for Testing and Materials (ASTM) standards. The tribological experiment was carried out at a constant 1800 rpm and different loads and temperatures. In addition, the surface morphology of the ball was tested by scanning electron microscope (SEM)/energy dispersive X-ray spectroscopy (EDX) analysis. The test results indicated that biodiesel fuels have a lower coefficient of frictions (COF) and lower wear scar diameter (WSD) up to 83.50% and 41.28%, respectively, compared to conventional diesel fuel. The worn surface area results showed that biodiesel fuel has a minimum percentage of C and O, except Fe, compared to diesel. In addition, the worn surface area for diesel was found (2.20%-27.92%) to be higher than biodiesel. The findings of this study indicated that both first and second generation biodiesel fuels have better tribological performance than diesel fuel, and between the biodiesel fuels, macadamia biodiesel showed better lubrication performance.

Advancement in lubricant technology is driven by technical demands, oil market, innovations from related chemical areas and other conventional factors. Nevertheless, a personal impact of an individual scientist can also be very important. Few individuals can claim to have accelerated lubricant progress more than Dr. Joseph M. Perez, who initiated many new developments in lubricant technology and drove them to large scale implementation. Early in his career at PennState he worked on aerospace lubricants, developing highly efficient additives for supersonic planes. When working at Caterpillar he dealt with hydraulic fluids, gear oils and many heavy duty lubricants. During employment at NIST and upon return to PennState Dr. Perez realized the importance of vegetable oils. He pioneered many research directions for their applications, becoming directly involved in vegetable-based engine oils, hydraulic fluids, greases, biodiesel, elevator fluids and many other areas. His innovative thinking, enthusiasm and initiatives will be sorely missed by lubricant researchers.
