Application Note: Short Block Crank Torque to Turn Test
A major engine manufacturer was experiencing customer complaints and costly warranty repairs and quickly required a solution that could detect defects early in the Short Block assembly process, specifically defects caused by crankshafts. Sciemetric’s Short Block Crank Torque to Turn test measures the torque as the crank is rotated, applying advanced algorithms for consistent and reliable detection of defects such as contaminated bearings, debris, incorrect fit, bent or nicked cranks, etc. Read the Application Note to learn more.

Application Note: Engine Assembly In-Process Testing (IPT) Using Process Signature Analysis
Why wait until end-of-line testing to find defects and root-cause when that leads to increased repair costs and lowers productivity. An engine defect can be introduced at any machining or assembly station, the sooner the defects are found the better. Sciemetric’s Engine In-process testing (IPT) solution finds and contains the defect(s) through various monitors installed along critical operations important for quality assurance, such as force, torque, leak, vibration, etc. With easy generation of yield and trend reports including full drill down, it’s fast to find to find root cause.

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. Read the Application Note to learn more.

Application Note | Piston Connecting Rod Fracture: Force Monitoring in V8 and V10 Assembly
An engine manufacturer required a solution to successfully monitor the crank force to verify the correct range of key parameters to ensure the quality of the connection of the connecting rods joining the pistons to crankshaft was not compromised. Sciemetric’s process monitor resolved the issue by closely monitoring the crank and peak force, bushing, falling slope and area under the curve while simultaneously monitoring both the cranking process and bushing press forces with a single system with a five second machine cycle time.
