Need to convert a gasoline engine to run on biogas - methane?

Answer 1

Jeffery S has it pretty close to correct. There are many applications in industry where gasoline engines are converted to run on methane. There are numerous applications using sewer gas to fuel engines to drive pumps or generators.

Assuming you are not going to try this with a car then it can be fairly simple. The trick is to get the methane at the correct pressure (usually only ounces of pressure) to feed into the intake of the engine. This is a bit different than using propane but only in the pressures you may be dealing with.

If you were going to try this with a vehicle then you have a real problem because the methane will need to be stored a very high pressure in order to get a sufficient volume to go any distance. This can be very expensive and very dangerous if you are not properly trained to handle 2000 to 5000 psi gas tanks and the needed pressure reduction systems.

Answer 3

I don't know about the methane....

To my understanding, the diesel engines manufactured today can run on bio-diesel and normal diesel with no modification.

E-85.... I feel it is a bunch of bull at this stage... The biggest savings I have seen verses gasoline is only 3%-5%. You get approx. 25% less mpg. It does have many environmental benefits, but try selling that to the general public. Also, you can't use E-85 in a normal car engine. The ethanol is so corrosive that you have to have stainless steel or nickel plating on surfaces exposed to it for long periods of time.. (tank,fuel lines,cylinders,pistons,etc.) It will also eat thru the normal rubber (buna, i think) used for the o-rings and gaskets on a conventional gas engine.

Answer 4

Same as Propane Butane LPG whatever you are calling LPG these days. You will need to look into fuel mixture and jet size though.

Hey you guys, biogas not biodiesel, read the question.

Answer 5

these E85 vehicles that the car companies are coming out with are very misleading here are the reasons
#1 E85 fuel has 15% alcohol in its make up which means it has less BTU's per gallon (BTU = British Thermal Unit)
#2 Less BTU's per gallon means you need to burn more fuel than you would with gasoline
#3 Burning more fuel to achieve the same distance you would in a full tank of gasoline is taking a step backwards.
#4 If gas costs $3.00 per gallon and you fill up your tank of 22 gallons that's $66.00 dollars this gives you a range of 400 miles per tank COMPARE E85 2.90 per gallon times 22 gallons equals $63.80 distance traveled with a full tank of E85 309 miles per tank
#5 The cost of buying a new vehicle well that's just priceless
Bonus answer you cannot build a engine to support 2 different types of fuel and make it run well on either or Example do you see any combination Diesel slash gasoline vehicles.

Answer 6

The conversion to methane should be very similar to converting to run on any gas. Check out conversions for propane.

Because is just a fake: chemically speaking it is impossible to oxidize water in a combustion engine in order to win energy. Water already is the product of an oxidation. Would be similar, if somebody invent a stove which is run on ash instead of wood.

Answer 8

I think you need a diesel engine, or somehow convert your gasoline engine to a diesel engine. You're going to need to change the spark plugs to glow plugs, modify the ignition system... Don't forget to add lube into the fuel, or your engine will burn out. Then you'll never need gasoline again.

Answer 9

Yes, we all need to do that. When you find out how to do it, don't let the oil companies know; they'll have you killed.

Answer 10

Yes, but what is your question?
