New Generation N62 Engine
The steel forged connecting rod is split.
As the connecting rod eye is split at 30º, it is possible to carry
out the cranking in a very compact space.
The pistons are cooled by oil jets on the exhaust side of the
piston crown.
The pistons for the B36 and B44 engines are made by different
manufacturers and have different diameters.
If a cylinder is redressed, the pistons are available in two
oversizes.
