What fuel will airplanes run on once fossil based fuels are exhausted?
Q. Cars have options of bio fuels and electricity.. Ships have nuclear options... But what fuel option does an airplane have? We hear of airline fleets expanding and newer, better and bigger airports being built all the time, but is there an eternal source of jet fuel?

A. Sorry if this answer is too long...but its the only way to describe it... My guess is that when things start to get tight there will be two options for aircraft and they will utilize both... First is ethanol... farm high sugar content crops... ferment them to convert to ethanol... a few additives and you've got some pretty good avgas. (Of course biofuel could work good for jet fuel too!) Second is solar energy... planes that have demonstrated this have been light in weight, with the majority of their weight actually being solar cells... Also because the cells are rigid and straight the wings on the plane were more "rigid" on top. They didn't have that nice curve that generates the most lift. Solar companies are now developing solar cells… [cont.]

How do I retrieve all the fuel from the fuel tank?
Q. We ship a lot of cars to other countries and it would be ideal to get all the fuel out of the tanks before we put the cars into containers. Most of these cars have filters in the fuel filler neck, so siphoning is not an option. I was wondering if it was possible to rig up a connection to the 'air' valve in the engine compartment (on the fuel rail) and turn the car on allowing the fuel pump to pump all the fuel out? Thanks for the answers and any other sugestions.

A. you take the return line off after the regulator on the fuel rail remove gas cap to keep the pressure in the tank down hook up a hose to the regulator out put run hose into fuel container or other vehicle start car and it will run until it runs out of fuel hook back up all hoses and put cap back on on the other end of shipping add 5 gallons of fuel and start UP the car

Is a propane fueled fuel cell capable of replacing grid power for home use commercially available?
Q. I want to disconnect from "the grid" and generate my own power on a continuous basis using propane for fuel. Most commercially available fuel cells for electrical generation are for back-up power only and require pure hydrogen to operate. I don't know why the industry isn't interested in the home market, but there seems to be no effort spent on this. If you know of any company that is working on this or currently has such a fuel cell, please provide details. Thanks.

A. There are a couple of vendors with home units available. Honda is one of them. They are very pricey and the electricity they generate may not be cheaper than the grid yet.

How do you clean fuel injectors that have had diesel fuel accidentally run through them?
Q. I would like to clean them on the truck, but right now the fuel is squirting out of the fuel rail where the fuel regulator plugs in.
Asked by Todd And Kelley - Tue Feb 23 19:01:47 2010 - - 1 Answers - 0 Comments

A. Diesel fuel should not hurt them in the least. It is less corrosive and is a good rust inhibitor. Anything you tried to clean them with, other then gasoline, would be much worse. So they will clean out as soon as you run real gasoline through them.

How can I test a fuel pressure regulator if the car does not start?
Q. I took the car to a mechanic yesterday who said the fuel pump was bad. I'm assuming he said this because there wasn't enough fuel pressure. I am still having the same stalling issues. I have read the fuel pressure regulator can cause this. I have personally replaced alot of other parts to rule out electrical problem. Any advise on how to test the fuel pressure reg will be appreciated. thanks.

What is the fuel efficiency of a chainsaw?
Q. I'm doing a project for school to analyze the efficiency of a chainsaw engine. I've prowled the internet and can't find a number to say how long a tank of fuel lasts for a chainsaw. I guess it's because there's no quantity like miles per gallon as there is in automobile engines. Anyone with a chainsaw, what is the volume of your fuel tank, and how long does it take to run out. Even better, how many trees could you cut down on one tank of fuel?

A. There are as many different size chainsaws as there is types of wood. Red oak is harder to saw through than pine. A saw of 40cc running at 1000 RPM uses less fuel than a saw of 60cc at the same RPM, but might take longer to get the same job done. An experienced cutter can get a lot more wood cut in a given period of time than an inexperienced cutter. There are too many variables in play to make a good estimate.

Asked by nick - Mon Sep 17 18:57:56 2007 - - 2 Answers - 0 Comments

A. I would say you need a pump with a higher fuel volume not pressure. You can run 10 PSI but 1 GL per min and 10 PSI 10 GL per min. That is just an example to demonstrate the concept in numbers (no real systems numbers). Do not let the PSIs fool you. You need on my understanding more fuel Volume, no Pressure. There is also a return line back to the tank. If you have nothing to restrict the flow, you will not be able to sustain any volume / pressure. Is like a hemorrhage of fuel back to the tank. The fuel system is like any Hydraulic system or Electric... It will flow through the path of lowest resistance. OMHO I would kept it Fuel Injected, less headaches and tunes better. :-)

Why does fuel consumption in a typical turbofan engine decrease with altitude increase?
Q. Why is it that when a aircraft is higher up, such as at FL360, it uses less fuel than if it were at FL180. Please note that the engine power setting is the same. Example 65% for both cases. I believe a jet engine compresses air, hence why it is more effective at high altitudes. So if it compresses air before ignition, wouldn't that mean you would still need just as much gas as when you were lower down?---(talking about fuel/air mix ratio here.)
Asked by David S - Sat Jan 12 21:18:34 2008 - - 4 Answers - 0 Comments

A. For the combustion inside a jet engine to occur, the mass ratio of the fuel to air (actually oxygen) must remain within a fairly narrow band. As the altitude increases, air is less dense - meaning less mass per unit volume, so the appropriate amount of fuel mass is also reduced. Regarding engine power setting - this is a setting where 100% is the maximum, the actual power (thrust) produced will vary with altitude. For example, a large turbofan may be able to produce 50,000 lbs of static thrust at sea level (FL0), but only 40,000lbs of static thrust at FL200. Jets go faster with increasing altitude (up to a point) due the dramatic decrease in air resistance, which falls off faster than the reduction in power (thrust).

A. The two terms are used interchangably to describe the same type of product.The injector/fuel system cleaners break up and remove the varnish like residue that builds up in the fuel lines and fuel injectors. These deposits begin to cause the injectors to spray the fuel in an erratic pattern causing a loss of performance and economy. Some products can also break up the carbon deposits that build up in your engine that also cause reduced performance, but mostly all of them are intended to do the same job.

The higher the octane number the SLOWER the fuel burns, so if you ran 100 octane in an engine that only required 87 you would not only be wasting money but the tops of your pistons and valves and valve seats would have a thick layer of black gunk on them due to the unburnt fuel blowing out of your exhaust.
