Fuel injection is the method that fuel is delivered to the engine, in older cars they used a carburator to mix the air and fuel.\n\nIn fuel injection there is acctually a pressurized injector that puts it into the engine.\n\nThere are 2 main types\n\nTBI - throttle body injection, where there is a thing like a carburator called the throttle body that limits the air into  the engine, and fule is injected there.\n\nBut most newer cars use MPI - multi port injection, where there is an injector for each rail of the intake manifold (ie 1 per cylineder) that injects fuel right towards teh back of the valves, generaly this system will produce more power then TBI, which is why it is used more

Not the full 100% it will be mixed or another fuel source will be found.

Yeah...  What Marky said.\nThen add a performance chip, fuel injectors (if necessary), larger throttle body, and mass air flow sensor (if applicable). Intake manifold....\nThen put a huge Turbonectics Turbocharger on it!\nTo go faster, you need to get more air and fuel in, and more exhaust out.\nHave fun!!

If you're doing this to save on fuel economy, you're kind of missing the point.  Your engine needs the same stoichiometric amount of fuel to run, no matter the dilution level.  In other words, your engine will burn the same number of gasoline molecules, whether or not there is water present.

butane (unreliable) propane (many cars are converted to this) hydrogen (next true fuel) and of course diesel which is used everyday

Various Injection Schemes\n[edit]\nThrottle Body Injection (TBI or CFI)\nThrottle-body injection (called TBI by General Motors and CFI by Ford) was introduced in the mid 1980's as a transition technology to individual port injection. The TBI system centrally injects fuel at the throttle body (the identical location where a carburetor introduced fuel). The induction mixture passes through the intake runners just like a carburetor system. The justification for the TBI/CFI phase was lower cost. Many of the carburetor's air induction components could be reused such as the air cleaner, intake manifold, fuel line routing, which postponed the design and tooling costs that were later incurred during the next phase of fuel injection's evolution, which is individual port injection commonly known as EFI. TBI had all the drawbacks of a carburetor, and all the drawbacks of early automotive electronics.\n\n[edit]\nContinuous Injection\nBosch's K-Jetronic or CIS used a continuous injection method. Gasoline was pumped through a large control valve called a fuel distributor, which sat atop a control vane mounted in the air intake pathway. The fuel went from there to the injectors on each cylinder's intake port (which were simply nozzles with no valves in them). The system worked by varying fuel mixture based on the amount of air flowing past the control vane. This system was used for many years on Volkswagen and Mercedes-Benz cars. There was also a variant of the system called KE-Jetronic that used an oxygen sensor to fine-tune the mixture.\n\n[edit]\nCentral Port Injection (CPI)\nGeneral Motors developed a new "in-between" technique called "central port injection" (CPI) or "central port fuel injection" (CPFI). It uses tubes from a central injector to spray fuel at each intake port rather than the central throttle-body. However, fuel is continuously injected to all ports simultaneously, which is less than optimal.\n\n[edit]\nSequential Central Point Injection (SCPI)\nGM refined the CPI system into a sequential central port injection (SCPI) system in the mid-1990s. It used valves to meter the fuel to just the cylinders that were in the intake phase.\n\n[edit]\nMulti-Port Fuel Injection (PFI or EFI or SEFI)\nThe goal of all fuel injection systems is to carefully meter the amount of fuel to each cylinder. On most gasoline applications, the system uses a single injector per cylinder and injects fuel immediately ahead of the intake valves.\n\n[edit]\nDirect Injection\nSee also: Gasoline Direct Injection\n\nRecently many diesel engines feature direct injection (DI). The injection nozzle is placed inside the combustion chamber and the piston incorporates a depression (often toroidal) where initial combustion takes place. Direct injection diesel engines are generally more efficient and cleaner than indirect injection engines, but tend to be noisier, which is being addressed in newer common rail designs.\n\nSome recently designed hi-tech petrol engines utilize direct injection as well. This is the next step in evolution from multi port fuel injection and offers another magnitude of emission control by eliminating the "wet" portion of the induction system.

You measure the amount of fuel put in.  Using the flow of that fuel (cubic feet per hour), you then determine the amount of energy in each cubic foot of that fuel (or look it up - Natural gas is 1020 btu/cubic foot).  Then measure the amount of heat given off and the amount of electric produced.  \n\nEnergy out (Btu's) / Energy in (Btu's) = efficiency.  \n\nYou need to convert the electric out to btu's by multiplying the kW to Btu's (multiply by 3412).  With the heat given off, you need to determine the temperature of the exhaust and the amount of air flow of that temperature and that will give you the thermal side of the output.

there are different type of pumps but basically the pump is rotated by motor. fuel flows into the pump and by pump's rotation, its outflow will have higher velocity.

Scrap both ideas and get a cam, port the heads, and carburate it.  You'll see more results than fuel injection for a very reasonable price, a pre GenIII small block like yours is cheap to build up!

Try creating alternative fuel. I'm reduced to cycling since the recent fuel price increase.

do something on alternative energy or fuel sources. or hybrid machines.
