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.]

What would cause fuel injectors not to work?
Q. I have a 90' GMC suburban. That recently broke down. Engine shut off and would not start. Fuel pump is working fine, fuel filter etc. Throttle linkage is also fine. My guess is something electronic, maybe a safety feature is causing the fuel injectors not to release fuel. All fuses have been checked. Any ideas for things to check? It is an electronic fuel injected throttle body.
Asked by JoHnAtHaN S - Fri Sep 11 20:04:26 2009 - - 5 Answers - 1 Comments

A. 1...Try to spray starting fluid in throttle body while somebody turns the key and cranks engine.If it starts then you know its a fuel delivery problem.If it runs then you need to find out why its not getting fuel 2...Check for injector pulse.You can use a noid light or even a test light will work.Hook test light in series with injector plug and have someone crank engine while watching light.It should pulse/flash.If it does than you know the computer is trying to command injector. 3...If no injector pulse check to see if crank sensor is working.Check to see if computer controls power or ground when injector is fired.

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

How much fuel is consumed by airplanes than to cars?
Q. Does anyone know the ratio of airplane fuel consumption to ground fuel consumption? Also, what the *** is wrong with people these days isn't there a way to get better fuel mileage than 6-7 gallons per mile on an airplane, when you're traveling thousands of miles at a time?
Asked by V H - Sun Jul 20 11:33:18 2008 - - 3 Answers - 0 Comments

A. According to British Airways, a 747-400 plane cruises at 576 mph (927km/h), burns 3378 US gallons (12,788 liters) of fuel per hour, and carries 409 passengers when full: If the plane is 75% full, one passenger is carried 52.2 miles for each US gallon of fuel burned (22.2 km for each liter of fuel burned).This fuel efficiency exceeds that of almost all cars, when the driver is traveling alone. So, to answer your question, it is actually MORE fuel efficient to travel large distances in a place (Provided it is at least 75% full) than it is to drive the same distance. Depending on distance, it may also be cheaper. You see, you have to factor in the number of passengers that can fit in a plane and determine passenger miles per gallon.

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.

How much fuel would you save driving on two half tanks of fuel rather than one full tank?
Q. We all know that more weight requires more energy to move it. If a car has more fuel in it, it has more weight, hence more energy,hence more fuel required to move it. Ignoring all other factors such as more trips to the fuel pump and driving conditions etc, how much fuel would you save by using to half tanks of fuel opposed to one full tank? Lets assume a 50 litre tank and a car that goes to 35mpg (imperial gallon)

A. My personal opinion is it would use more gasoline but on a normal running system, you really wouldn't see the increase per say (as injectors are measured in flow plus how long they stay open).. it would cause the engine to run richer (and try to lean itself out to the point it will set a check engine light on a marginal system) but would it bring economy or power? nope unless you install other gear to help the fuel injectors do it's job as optimized.

Q. I have an 1989 s-10 2.5l fuel injected. It has the original fuel pump and it is not pumping at enough pressure to keep the engine running. How much pressure should I be getting?
Asked by jcrulz13 - Mon Aug 21 12:53:49 2006 - - 4 Answers - 0 Comments

A. This depends on if you have throttle body injection or port injection. Throttle body injection usually uses around 16 pounds max. Port injection can go all the way from 32 to well over 100 pounds. You need to call a parts store and find out what pressure your pump is supposed to be putting out. They can look in their fuel pump book and find the pressure rating in the back of the book. Also refer to your repair manual for the proper pressure at the fuel rail if it is port injected. Also check the fuel pressure regulator. Your pump might be working fine but the regulator isn't letting the proper amount of pressure through.

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. I wouldnt use an octane booster, its a product designed to increase the volotility of your gasoline to make it combust at a lower temperature.

Asked by Alex S - Fri May 5 03:17:05 2006 - - 8 Answers - 1 Comments

A. Ron is correct, the ONLY reason for higher octane numbers is to prevent detonation in very high compression engines. 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. Remember folks, octane does not make power!!

The intake will help some as well. Remember, the truck is forced induction, so it is sucking a lot more air than a naturally aspirated motor would.

A. Hi, yes your car is designed to run on 87 octane. If your vehicle rattles when the a/c is on, but doesn't when you run higher octane, you are hearing detonation. Detonation is bad and can damage the engine. There is a few things that can cause detonation. Most common is the engine is out of timing, but on your vehicle it should be controlled by the computer. If the vehicle has high mileage, it could have carbon build up inside the motor / cylinders / valves, etc. It also could be caused by a faulty EGR system. In your situation if it is a vehicle with high mileage, you may need to stick to the higher octane.
