Note two points in this illustration. 1: The presence of a radius fillet between the main bearing journal and counterweight. 2: The absence of a radius fillet between the connecting-rod bearing and ...

Assuming that you put the half bearing plates in their position and the crankshaft over them, you now have to put the other halves on and screw in the bearings, in the VVTi engine's case here all ...

The result is a multitude of twisting forces applied to the crankshaft the entire time the engine is running. The stresses are multiplied in a racing situation in which the rpm levels can get quite ...

ABSTRACT The authors have published SAE paper 2008-01-0088 on the analytical comparison between 4 and 8 counterweight crankshafts for an I4 gasoline engine. This paper showed that for a particular ...

It’s no secret that the easiest way to make more horsepower is to bump up the size of your engine. And, since an engine can only be overbored so much, the next, most logical, step is to install a ...

ABSTRACT Reducing friction in crankshaft bearings during cold engine operation by heating the oil supply to the main gallery has been investigated through experimental investigations and computational ...
