2 stroke

Just thinking about 2 stroke. Many people say it's impracticle, but with direct injection and an expansion chamber, it can be more efficient than 4 stroke. Also, only a few/ at least 1 car in production has had 2 stroke. It is called the Melkus RS1000. Also, look up the VanDyne SuperTurbo. It's exactly what it sounds like.
