Why don't automobile engines use direct air injectors just as there are direct fuel injectors to fill the cylinders? I would think it would be easier to move air than fuel. It would require compressed air from a Turbo or Supercharger to create the needed pressure. This would eliminate the need for an intake port and valve. You could even use multiple air injectors for optimum performance. This would also allow the exhaust valve to be relocated to a desired location to take full advantage of this approach. Your thoughts please. Thanks
