Back to scavenging. I was always under the immpression that the idea of valve overlap, was more geared towards getting the exhaust out of the pot, then getting extra fuel air mix in.
Would it not be the same amount of mix going in, just that it was combusting better, due to no co, which dosnt burn. |
You don't need a DV. Valve overlap is the norm, scavenging is totally normal with four stroke engines. It's simply a matter of the degree as to how much overlap is designed in.
VVT systems adjust the valve timing in real time simply to make the best of what is ultimately a compromise.
As of yet the automotive industry hasn't designed and built the ideal internal combustion engine,
