Are you tired of fiddling with the engines on your lawn equipment every spring, trying to get them to run again? [jhark] was and decided to do something about it by converting his riding lawnmower over to fuel injection. After stealing a fuel injector from his van and bolting it onto the mower’s carburetor, he sprinkled in a dash of Arduino magic. With a small amount of code tweaking he was ready to
roll mow. You can find a schematic and his code if you follow the forum link to the second page.
For more fuel injection goodness, check out this project where [Steve] upgrades his Austin Healey to use the fuel injection system from a General Motors vehicle. This build log is pretty comprehensive and shows each element in the system, describes what it does, and shows where it should go. If you are a car nut, this is definitely one to check out.
Finally, if you are looking to really dig into the nuts and bolts of automotive fuel injection, take a look at the Megasquirt fuel injection computer system that allows you to finely tune things to your specific car and model.
