Believe it or not, this scratch-built 0.045-liter V8 engine is fully functional.

It's the work of a man with a shed, a manual mill and a 95-year-old lathe.

Here's the builder's description:

"Scratch built 45cc V8 with Megasquirt MS2 fuel injection.made in the shed with an old manual Bridgeport mill and a 95 year old lathe. Single fuel injector made from Punto injector internals. Pressurised oil system, drilled crank, alloy block, cast iron wet liners, vernier cam pulleys, Walbro fuel pump, tungsten alloy flywheel, bead blasted and anodised finish, throttle position sensor on butterfly shaft, 24 tooth trigger wheel for megasquirt."

Of course, this isn't intended to be a range extender, but just seeing this tiny engine in action got us to thinking how or if something like this could work in a plug-in vehicle.  If we knew what the fuel consumption rate is and the engine's power output, then we could theorize how well it would or wouldn't work as a range extender.

What if something like this tiny engine ran all day to extend range?  Meaning, even if parked, a similarly tiny engine ran continuously in an effort to boost charge.  Would it work?  Would it be worth it to consume some unknown, but small amount of fuel if say a charger was nowhere to be found?
