Oil - Vegetable Oil

Vegetable oils are a triglyceride that is extracted from agricultural crops, these oils are natural products and therefore their chemical composition changes from one crop to another. They are used in engines and chainsaws as a lubricant instead of petroleum based oils. Canola Oil – made from rapeseed – is an example of a vegetable oil, it is cleaner than petroleum based oils and has less health risks as petroleum oils are commonly carcinogens and can cause eczema, but still is an excellent lubricant. Furthermore Canola oil is non-toxic for the environment.

Grease

Grease is a semi-solid lubricant. Greases have an initial high viscosity but after application the viscosity decreases. An example of a grease used as a lubricant is Silicone Grease, it is a good lubricant and provides resistance to corrosion. It’s used as a lubricant for bike chains and airsoft gun mechanisms and it’s made when silicone oil is mixed with a thickener. Silicone grease does not swell or soften rubber and so is used for lubricating rubber parts and preserving them. The temperature range of it is around -40 to 200°C with some extremes than can be manufactured. Due to its cheap cost and high availability, silicone grease has many different uses such as waterproofing underwater lights and cameras and possibly any other moving part.

Solid Lubricant – Graphite

Graphite is used as a lubricant due to its structure of molecules, it is made out of sheets of carbon atoms where the atoms have a strong bond with others in its plane, but a weak bond with atoms above or below the layer. This makes it a good lubricant because the layers of atoms can easily slide off one another. It is used as a lubricant when there are very high or low temperatures involved, for example a gear lubricant in mining machinery and most

    1.0 IntroductionBiodiesel is defined as mono-alky esters of long -chain fatty acid. It is a fuel that derived from the vegetable oils, animal fats, which is similar to the diesel fuel except that it is made from the crops. It is produced from domestically grown, renewable sources, such as crop oils or animal fats which are then chemically converted into biodiesel (Habmigren, 2003). Unlike diesel, biodiesel contains no petroleum products and free of sulfur compounds and aromatics (Habmigren, 2003). Until today, it is still the only alternative fuel for motor vehicle. The biodiesel blends have ranged from 2/98% (B2), 20/80% (B20), to 100% (B100) (Hafman, 2003). The reasons biodiesel is a viable alternative to diesel from fossil fuels for trucks and buses are it can reduce the pollution, it can enhance the country's economy, and it is renewable sources and can produce almost same energy as diesel fuels.…
