What is involved in converting a diesel engine to run on biofuel?
I am buying a diesel RV to do a tour of the country next year with my environmental organization and I want to convert the engine to run on biodiesel. I am interested in knowing both the ease or difficulty of having this done, as well as what sort of cost will be involved.
"Biodiesel is registered as a fuel and fuel additive with the Environmental Protection Agency (EPA) and meets clean diesel standards established by the California Air Resources Board (CARB). Neat (100 percent) biodiesel has been designated as an alternative fuel by the Department of Energy (DOE) and the US Department of Transportation (DOT)."

I think Zealot needs to do a little more research before talking about things they are not 100% sure about.
The above website will answer most of your questions regarding what Biodiesel is and how it is refined and blended for comsumer use.
It has been my experience that most places that vend Biodiesel, do so right alongside the pumps used for petroleum based diesel fuel. Look for signs as you pull your RV into the truck stop/fuel stop and the Biodiesel pumps will be clearly marked.
Good luck and hope this has helped....
Diesel Engine at is Finest
Diesel engines can be broadly distinguished as two-stroke and four-stroke. Bulky engines usually operate on the two-stroke cycle. Lighter engines generally operate on four-stroke cycle.
Generally cylinders are used in multiples of 2, 4, 6, or 8, .It doesn’t matter what number of cylinders are being used as long as the load on the crankshaft is counterbalanced to prevent excessive vibration. The inline-6 cylinder is used widely in medium and heavy duty engines.
How these engine work? The temperature of gas rises when it is compressed. When the inlet valve opens air is sucked into the cylinder of a Diesel Enginesdue to vacuum created. The piston then moves upward and compresses air raising its pressure and temperature. As the piston moves up towards the end of compression stroke, injection of diesel fuel the combustion chamber that is cylinder takes place. There is high pressure inside cylinder so the fuel is injected through an atomizing nozzle at reasonably high pressure. The mixture of fuel and air then ignites and burns rapidly. The gas in the chamber expands. This forces the piston to move down and thereby producing power stroke. The connecting rod which is linked to crankshaft forces it to turn and delivers rotary power at the output end of the crankshaft. Scavenging of the engine is completed either by ports or valves
Accessorizing a turbocharger is a vital accessory and is used to compress the intake air. To increase the efficiency an after cooler/intercooler is used to cool the air after compression. Speed of the engine can be controlled using Governor by adjusting the rate of fuel delivery. In cold weather conditions these Diesel Enginescan prove problematic. To overcome this problem small electric heater called glow plug is used inside the cylinder to warm the cylinders prior to starting. While you can also have resistive grid heaters in the intake manifold to warm the inlet air until the engine reaches operating temperature. Engine heaters fixed into the utility grid are mostly used when a Diesel Enginesis shutdown for long period in cold weather to lessen the startup time and engine wear.
