Utilizing a Modified U-Groove Design for High Performance Bearings
As performance engine builders know, the loads acting on engine bearings are generated by the pressure of the fuel-air mixture combusting in the cylinders. This pressure, or combustion force, drives the piston down during the engine power stroke. However, combustion force is not the only force generated by an internal combustion engine.
