Application Note: Long Block Verification

Missing piston rings in the engine caused a major engine manufacturer to experience excessive warranty charges from customers, and repairing this defect after the engine was installed in the vehicle was costly and time-consuming. Existing end-of-line testing was not detecting the missing piston rings or the resulting compression defects.

Sciemetric’s long block verification solution applied at critical points throughout assembly identified timing, measured torque, pressure and cylinder combustion pressure related defects that were having the largest impact on their bottom line and yield. Being caught before end-of-line testing methods resulted in a decrease repair and warranty costs.
