been doing some thinkin’
If an EGR valve was designed and implemented to reduce peak combustion temps in vehicle engines in order to drop emissions of noxious gases, would a stuffed up muffler on a two stroke do the same?
If so, the theory of reduced combustion temperature should lead to lower cylinder and combustion chamber temperature (at least that is what is stated in the explanation of EGR function).
Here’s where I’m going with this...
I have been working under he assumption that opening a muffler reduces restriction and promotes flow to make a two stroke run cooler.
This defies the logic of EGR design and combustion temperature. Does increased combustion efficiency actually raise operating temperature.
Has anyone ever tested this?
Are we all just operating on assumption?
Are there more factors at play here?
@Redbull661 - what say you? Are tests required?
