Introduction
Biodiesel can be used in nearly any diesel engine, with little or no engine conversion. However, biodiesel is a stronger solvent than regular diesel (petrodiesel) - so much so that it will not only "clean out" the fuel tank, sending debris into the fuel filter, but it will also soften and dissolve many rubber and plastic products, including those used in fuel lines, filters and pumps. This deterioration can take years, however, and the replacement of rubber components does not have to happen immediately. Thus for long life, a different grade of components is needed in an engine designed for biodiesel.
Biodiesel produces less particulates than petrodiesel and is thus much better for the health of the population, particularly those living in urban areas exposed to significant levels of pollution.[verification needed]
While W can be used as fuel, it has a negative effect on the engine after prolonged use. Thus it is better to process the oil into biodiesel, especially for vehicles which get heavy use.
Sources
Biodiesel can be made from any[verification needed] fat or oil, such as:
- fish oils (e.g. in Norway[1])
- vegetable oils, which are now often cheaper than regular fuel,[verification needed] if bought in bulk, and we consider that premium cooking oils are not needed.[verification needed]
- used deep frying fat or oil (which would normally be discarded, at economic and environmental cost) - take-away food shops typically have a regular output of this waste.
- Even fat from liposuction operations should be able to be used.[1]
Suggested projects
- Search for literature discussing the health impacts of vehicle pollution, and different aspects of the pollution such as particulates vs other pollutants.[expansion needed])
- Design a relatively simple, reliable way of converting vegetable oil (waste and/or new) into biodiesel, to minimize the technical expertise and resources needed, perhaps making it more practical for production in small or medium-sized remote towns.[expansion needed]

Notes
- ↑ Fortune in fat, Aftenposten, 6 Dec 2006. Norwegian businessman Lauri Venoy owns a firm in Miami, Florida, was reported to be making an agreement with US hospital giant Jackson Memorial to supply 11,500 liters of human fat per week from liposuction operations.
