nVision Crankshaft revealed
Having written about the new nVision engines yesterday, a chance encounter with Adrien Bertin and Yannick Aigoin resulted in pictures of the newly developed and quite radical crankshaft. As you can see from the photos, the fuel enters the crankshaft as normal but is sent into the combustion chamber through the 4 holes on the crankshaft end plate. The ensures that the fuel is thrown directly up into the liner more efficiently, instead of being splashed off the back plate. We were also told that the NVB521R race spec is the only engine of the two to be announced to feature this new crankshaft.
