What’s the difference between Biodiesel and PPO?
Plant oils can be used to run diesel engines. Problems occur because plant oils are generally too thick and heavy for the fuel pumps and fuel injectors to cope with. There are two ways to solve this problem – either make the plant oil less thick and heavy, or make the vehicle more able to cope with thick and heavy fuel. Biodisel has a much heavier environmental impact than using PPO. PPO makes sense for local production and represents the best possible environmental performance from any of the available biofuels. B) Thinning the oilThe most common and well known method is to turn plant oil into Biodiesel. The oil molecule is chemically split, separating the free flowing esters from the heavy glycerol content. Biodiesel is a well recognised fuel which has a vast amount of scientific research behind it, and fuel standards are in place, along with a fledgling, but well financed and growing global industry. There is another method of thinning plant oil, which involves mixing it with a solv
