Abstract:-Biodiesel has recently received increasing attention because of many advantages such as higher cetane number and flash point compared to diesel fuel.

However, corrosion of engine parts exposed to biodiesel or biodiesel-diesel fuel blends is still a critical challenge in the biodiesel industry. In the existing literature, there is still a lack of systematic studies including corrosion process in light alloy and changes in mechanical and fuel properties of engine parts (such as brass) after exposure to biodiesel.

:- Therefore, in this study, (1) waste sunflower oil biodiesel (WSOB, B100) was supplied and blended with diesel fuel (B0) at the volume ratios of 10%, 20%, and 40%, which are called as B10, B20, and B40, as usual.

1. NTRODUCTION

   In recent years, rapid exhaustion of world petroleum reserves, rising prices of fossil fuels, and growing environmental concerns have propelled researchers to seek for renewable energy sources (Chien et al., 2009; Behc¸et et al., 2015).

   Biodiesel is one of the most promising alternative clean fuels to diesel fuel. Biodiesel is generally produced by means of transesterification reaction in which triglycerides in a vegetable oil or fat react with a simple monohydric alcohol (usually methanol or ethanol) in the presence of a suitableThe most common brass is nominal brass which contains 70% copper and 30% zinc. It is also known as cartridge brass this brass is subjected to dezincification if left for long times in water, the zinc disappears and the metal has a dull copper color as copper is all that is left on the surface. Brass with less than 15% zinc is sup- catalyst, after ten days of immersion were taken using Optical Microscope. The photomicrographs were done without etching to reveal the surface property at a magnification of 700 The samples were prepared for the study by cutting brass into 1 cm2 coupons and soaking them in different small plastic containers containing petrol, kerosene and diesel. The corrosion rate of each sample for a specific period of immersion (120, 240, 360, and 480, 600 and 720 hours) was determined on average of three samples exposed under the same condition and test media in different container. The finding showed that brass is resistant to corrosion after long hours of contact in chosen liquid fossil fuels..

3. METHOD

   The samples were cut into coupons of 36 pieces using shearing machine and arc saw. The plastic containers were first washed with detergent, rinsed in distilled water and allowed to dry for hours. They were filled with testing fluids which were petrol, kerosene and diesel. Each of the measured samples was inserted into identified plastic containers. Complete immersion in testing fluid was ensured for periods of 120, 240, 360,

   480, 600 and 720 hours. Proper cleaning of each sample was ensured after removal using water and mentholated spirit. After each period the samples were removed and weighed to determine the weight loss. The data were collected from the experiment and analyzed. Photomicrogrsamples

4. RESULTS AND DISCUSSION

   Corrosion rates of brass in petrol, kerosene and diesel were low after long immersion period. Corrosion rate of brass in petrol was the highest, followed by brass in kerosene (both almost have the same pH of about 6.95 and alittle increase from acidic to alkalis). Brass in diesel has the least corrosion rate and the pH was slightly less thanthat of kerosene and diesel which increase toward neutral. Diesel was most viscous among petrol and kerosene

   Fuel is filled and stored in a tank of some type. The fuel will interact with materials and impurities in both storage tank and fuel system. The fuel will also be exposed to various ambient conditions suchastemperature moisture and exposure to oxygen in air. Examples of dependence are vapor pressure, connected to high and low temperatures, deposits depending of low temperature solubility and oxidationstabilitydepending

      In conclusion, the influence of liquid petroleum products on the corrosion rate of brass was investigated and the following findings were deduced from the study. The corrosion rates of brass in petrol, kerosene and diesel were low after a long period of contact.Corrosion rate was highest for brass in petrol than in kerosene, and the rate

      was least in diesel at early hours of immersion. Energy

      content of isobutanol is 33 MJ/kg (26.5 MJ/l) representing around 82% of volumetric energycontent of gasoline. Densities of butanol isomers are higher than those for gasoline, which improves volumetric fuel economy to some extent. Theoretically, volumetric fuel consumption increases some3.5% when 16 vol-% butanol is blended with non-oxygenated gasoline.
