Sure, 25cc Fuji Imvac 4stroke modellplane engine, ported head, Raised compression, converted to watercooling with a waterjacket around the cylinder, no throttle, runs on pure ethanol (E100).-----> Flywheel------> generator which is a 3-phase electric modellplane motor running backwards as a generator------>Rectifier-------> Super capacitor which acts as a buffer for the electrical motors which turns the wheels (one for each wheel). So it's a series hybrid with no mechanical link between the ICE and the wheels. This means that the engine runs at about 5k rpm when it's charging and then it shuts off until the cap is drained beneth a specified voltage.
It's originally a build for the Shell Eco Marathon so the rules for the competition has set the limits for which components we can use.
