Essential Tips On The Excellent History Of Biodiesel Fuel
Dr. Rudolf Diesel invented the well known diesel engine, in the 1890s. The engine’s development was basically an answer to the rudimentary steam engines that had been in existence since the auto-mobile emerged. The steam engines were inefficient and could be dangerous, and the diesel engine was lauded for its reliability as an alternative.
Unlike the petrol engine that was to gain wider acceptance, the diesel engine operates on the basis of compression – ignition. Air enters into the engine cylinder and is compressed when the piston rises, igniting the mixture and emitting power. The petrol engine on the other hand uses a spark to ignite a fuel/air mix when the air is compressed, and needs a somewhat complex “backup” system of plugs, coils and leads.
It is said that the public first got to see the early biodiesel engine at the turn of the century, but it was to be the 1930s before biodiesel fuel was developed, at the time when the oils were converted into fatty acid methyl esters.
Following the war period and during times of relative plenty, there was little real interest in biodiesel as an alternative. When petro diesel was readily available and quite cheap, vegetable oil based alternatives were not suitable. As the vegetable oil was subject to a higher viscosity, experimentation resulted in further development and the emergence of what we now know as biodiesel.
Transesterification, the process of converting vegetable oils and making them available as a diesel fuel replacement was initially mooted by a Belgian inventor back in 1937, but it was not perfected until the 1980s, when complex socio-economic factors combined to draw our attention towards efficiency and energy security. At this time the process was perfected, making biodiesel fuel a very real alternative for environmentalists and those concerned about society.
Biodiesel first gained widespread acceptance in Europe in the 1990s, due to much higher prices of petro diesel. Biodiesel first went into production in the US in 1996, and during the decade to follow it has become more and more available and the subject of more interest in general.
