The Benefits of Biodiesel Fuel

Benefits of Biodiesel

  • Easy – no conversion to your vehicle and biodiesel can be splashblended with diesel at any time in your fuel tank. 
  • Non-Toxic – biodiesel is the only alternative fuel to have completed the EPA Tier I and II health testing. The test results concluded that biodiesel is non-toxic and biodegradable, posing no threat to human health. 
  • NonFlammable – biodiesel will only ignite at a very high temperature (350° F). As a comparison, gasoline ignites at -43° F. 
  • Good for Your Engine – tests show that biodiesel is more lubricating to both your fuel injection pump and engine than diesel fuel and so may prolong your engine life. 
  • Renewable – biodiesel is made from 85% vegetable oil, a renewable resource. 
  • Cleaner Emissions – greenhouse gases, particulates, and carcinogens are greatly reduced. 
  • Sustainable – in a cradle to grave life cycle analysis, biodiesel comes out positively. For example, one study showed that biodiesel yields 3.2 units of fuel product energy for every 1 unit of fossil energy consumed in its life cycle. By contrast, 1.2 units of fossil resources are used to make 1 unit of diesel fuel.

And what’s the difference between a gasoline engine and a diesel engine, anyway?

— A gasoline engine intakes a mixture of gas and air, compresses it and ignites the mixture with a spark. A diesel engine takes in just air, compresses it and then injects fuel into the compressed air. The heat of the compressed air lights the fuel spontaneously.   

— A gasoline engine compresses at a ratio of 8:1 to 12:1, while a diesel engine compresses at a ratio of 14:1 to as high as 25:1. The higher compression ratio of the diesel engine leads to better efficiency. 

— Gasoline engines generally use either carburetion , in which the air and fuel is mixed long before the air enters the cylinder, or port fuel injection , in which the fuel is injected just prior to the intake stroke (outside the cylinder). Diesel engines use direct fuel injection — the diesel fuel is injected directly into the cylinder.
