whats important about a gas engine?

What isn't important? Think about it, the internal combustion engine completely revolutionized the world.  Without it, nothing would be the same.  \n\nI guess if I had to make a list I would start with the fuel lines, with out fuel nothing will take place.\n\nCarbeurator is next, controlling the input of air and fuel.\n\nThe heads, pistons, spark plugs, and exhaust manifolds are pretty important too.  The pistons compress the fuel, it is then ignited by the spark plug.  The resulting gas exits the exhaust manifold and out the tail pipe.\n\nThe cam or crank shaft spins in an orderly fashion to move the pistons in the correct sequence.  The distributor makes sure that the spark plugs fire at the proper time.\n\nI could go on forever.  Basically, the engine doesn't work properly if all parts aren't working.  I guess that means everything is important about a gas engine.

It’s a pressure system, using pressure the gas or oil is moved through the system, that’s why you cant have any leaks, otherwise you lose that pressure, and gas and or oil is pumped through the system properly. Also why you have an “Oil pressure” light or picture etc, on the dash, its moved by pressure, and the loss of pressure can lead to major problems.

thats basically the idea of a hybrid engine, except instead of powering a house, it helps power the car. see, electric motors actually work as electric generators in reverse, so hybrid cars have a gas and electric motor. the electric motor generates power when braking, which is stored in batteries. then, when you start up again, the electric motor helps accelerate so the gas engine doesnt work so hard. its alot easier and more efficient to use the stored enrgy within the car rather than putting it into the power grid.

Actually what you want to build is an electric *motor*, not an electric *engine*.  By definition, an engine has a number of working parts that move sychronously, whereas a motor is a simple moving machine (my English teacher nailed me on this back in the 12th grade and I've never forgotten it).\n\nBut nevermind all that semantics stuff.  See the link below for some excellent how-to examples, depending on how powerful a motor you want to make.\n\nHave fun!

It's a computer module that monitors and regulates a lot of things in an engine. With input such as revolutions (rpm), oil and water temperature, air density and oxygen levels in the exhaust it determines and regulates things like the firing moment of the spark plug and the amount of fuel to be injected ito the cylinder.\nPlease read the link: http://en.wikipedia.org/wiki/Engine_Control_Unit

Jet engines are very precisely calibrated and need a higher octane fuel (regular car fuel is about 83-97 octane, the efficiency at which it burns).

An internal combustion engine perhaps?

Internal combustion engine.  Without it transportation as we know it today wouldn't exist.  We'd still be using the horse and buggy.

Answer is wear & tear... Old cars have engines which has undergone wear will have loses throgh pistons,valves, gears etc. Due to improper/inadequate maintenance, frictional losses will be higher with time. With proper maintenance of cars/equipments you can keep fuel consumption low.

It depends on the impurities in the gas and the temperature of the gas.  If you have high chlorides and thermal cycling, you may need alloy steel.\n\nFor a pure hydrocarbon stream at less than 60°C, carbon steel would be fine.

do you mean petrol?\n\nif so a gas engine works on the spark theory in that you have a closed combustion chamber in which parts of air and fuel are mixed together then ignited by a spark plug. \n\nA Diesel runs on the Pressure Theory in the sense that it requires no spark plug because simply it ignites the fuel by pressure.

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.

well...\n\nlook for performance:\nheaders\nexhaust pipes\nmufflers\nintake manifold\nair filter\ndrivetrain pulleys\nfuel injectors\nthrottle body\nfuel pump\n\nsupercharging the motor always helps. =]\njuss make sure u upgrade ur brakes too, though. lol.

well an upgraded clutch and flywheel, helps hold the horsepower and tourque created by an enhanced engine. If you have done any serious motor upgrades(i.e. big turbo, bore, port polish and big time spray) yeah you need a better than stock clutch

Natural gas comes from the ground like oil, except that it's a gas and not a liquid. There are pockets of it all over the world (again, similar to oil).\n\nIt produces electricity similar to a car engine. Some engines are designed to run on natural gas instead of gasoline. Once the engine gets running, it is hooked up to a generator which produces electricity.
