With this project I'm converting my '96 Suzuki Bandit from a carburetted motor bike to a fuel injected one. The engine of said motorbike needs an ideal mixture of gasoline and air to make the cilinders go boom. On the bandit, this is done by means of carburettors. This roughly boils down to the following principle. Engine sucks in air, carbuterror does some mechanical thingy to allow the right amount of fuel to get sucked in with the air. Ideal mixture reaches engine, stroky, sparky, boom. Ofcourse this is all very cool if you like easy stuff, but I like hard stuff. So, out with the easy, in with the hard.

Of course, we still need the ideal mixture, because to much fuel per air makes for a smelly motorbike and you will visit the pumpingstation more often than you'd care for.

With fuel injection, an injector is mounted directly in front of the air intake port of your engine and blasts the engine with heavy loads of fuel as air gets sucked in. The engine swallows this mixture whole and starts revving up, begging for more. As the engine revs up, it sucks in more air, and now we have problem. More air, means more fuel, otherwize the engine will burn. We gotta cool that engine. So, how do we know how much fuel to give it to the engine? And how do we drive the injectors in the first place?

With this project I'm converting my '96 Suzuki Bandit from a carburetted motor bike to a fuel injected one. The engine of said motorbike needs an ideal mixture of gasoline and air to make the cilinders go boom. On the bandit, this is done by means of carburettors. This roughly boils down to the following principle. Engine sucks in air, carbuterror does some mechanical thingy to allow the right amount of fuel to get sucked in with the air. Ideal mixture reaches engine, stroky, sparky, boom. Ofcourse this is all very cool if you like easy stuff, but I like hard stuff. So, out with the easy, in with the hard.

Hard stuff

Of course, we still need the ideal mixture, because to much fuel per air makes for a smelly motorbike and you will visit the pumpingstation more often than you'd care for. Too little fuel per air makes your engine burn up. Yes ladies and gentlemen, fuel cools your engines. Bet you didn't know that. Anyway, we still pretty much want the same thing, ideal mixture, we just want it to be delivered in a way that's challenging for a nurd. So, the alternative is fuel injection. With fuel injection, an injector is mounted directly in front of the air intake port of your engine and blasts the engine with heavy loads of fuel as air gets sucked in. The engine swallows this mixture whole and starts revving up, begging for more. As the engine revs up, it sucks in more air, and now we have problem. More air, means more fuel, otherwize the engine will burn. We gotta cool that engine. So, how do we know how much fuel to give it to the engine? And how do we drive the injectors in the first place? The answer to the first question is not that easy (hard remember) so I'll save that for later. The answer to the second one is: We need an Engine Control Unit, or in american: ECU. The ECU is the device that determines what the engines needs, and gives it to her.
