With Direct Injection Would a 2 Stroke Need An Expansion Chamber?
With the basic understanding of how an expansion chamber works by forcing or rebounding unburned fuel/air mixture back in to the cylinder through the exhaust port, and the fact that Direct Injection would not allow unburned fuel mixture into the exhaust, would there be any benefits to having an expansion chamber? And here is another head scratcher, would direct injection eliminate the 'Power Band'??
Does anyone have any feedback on this? How about the PWCs or Skidoos with direct injection? Are they still using expansion chambers?
It will be a great day when the carburetor on a two stroke motorcycle is replaced by direct injection or maybe something even better.
