How Can you turn ANY Car to Run on BioFuel?
That depends on what you define as biofuel. Technically all fossil fuels are biofuels, they just happen to be from ancient life and transformed by geologic processes over millions of years. It’s quite possible to synthesize fuels like gasoline and diesel directly from biomass such as trash, dried sewage and storm debris and we already have much of the infrastructure involved on an industrial scale. You simply have to gasify the biomass into syngas much as we currently do in the plasma torch incinerators of waste disposal plants then use the syngas in Fischer Tropsche synthesis reactors to produce the gasoline and diesel much as we now do with syngas made by gasification of natural gas to produce synthetic diesel with which we dilute our high sulfur diesel in order to meet the new federal ultra low sulfur diesel requirements (Shell’s GTL plant, and the upgraders of the tar sands are such gasification/FT reactor operations). Of course such synthetic fuels have a much higher cost basis then letting nature do all the work and drilling a hole into nature’s reserves hence synthetic fuels are unlikely till a relatively high fuel price can be guaranteed, that is it’s not enough for gasoline prices to reach $4 a gallon in the US but rather for investors to believe that it will not drop below $4 a gallon for at least fifteen years, even then there would be a much larger profit to just drill for oil.
As to the traditional bio-fuels. Gasoline based cars with fuel injection can easily be converted to run on ethanol as it simply requires a different air fuel mix ratio and that is controlled by computer in a modern fuel injection car. Diesel cars can run on vegetable oils since diesel engines were originally designed to run on vegetable oil but there are problems with how thick vegetable oil is when compared to petroleum based diesel so care must be given to either transesterfy the oils into shorter chain esters or to heat both engine and vegetable oil before using the vegetable oil as a fuel. The latter is done by running the engine on regular diesel till it’s hot and till heat from the engine coolant can heat the vegetable oil to the appropriate temperature before switching to the vegetable oil and to switch back to diesel as you approach your destination so that a few minutes of running on diesel will purge the engine and injectors of the more viscous vegetable oils.
Gasoline engines can also run on butanol without any modifications since the burn characteristics of butanol is very similar to gasoline. However most butanol is made from petroleum even though like gasoline and diesel, it can be made from either petroleum or biologic sources.
So yes, any car can be modified to run on biofuel but the modifications and suitable biofuels are different between gasoline and diesel cars as well as depending on which biofuel you are talking about. More importantly, any fuel can be a biofuel, a fuel is simply a method of storing energy chemically much as a battery does, it’s how that energy is captured from the sun that determines whether or not it’s a biofuel.
