Last week I went on a Ducati factory tour.
Really interesting to see inside these motors, the pistons are such a huge diameter, and yet SO short, it’s incredible,
They had a sectioned engine that turned over via an electric motor. You could see the Desmo valve gear in operation.
The exhaust cam was fascinating, it appeared to have what I can only describe as slow motion valve bounce!
The exhaust valve opened and closed as normal, but then opened and closed again, just a little bit.
It wasn’t an error, you could see the cam had clearly been made to do this.
Does anyone know WTF it does this for ??
Allowing in a little more unburnt exhaust gasses that are pushed back in via a pressure wave is all I could think of... anyone know any better...?
