7 Outstanding Rotary Engine Swaps
The fast, the furious, and the tasteful. The main difference between rotary and your more standard combustion engines is that rotary engines don't use pistons. Essentially, one or more triangular rotors spin in a circular chamber to combust the fuel/air mixture, which is a lot less complex of a solution than using pistons. Other advantages include less mechanical stress, less vibration, higher power-to-weight ratio than a piston engine, higher compression, the ability to use a wider range of fuels, a wider torque band, and better thermodynamic efficiency. It all sounds wonderful when describe...
