Application Note: Transmission NVH Testing
The engine manufacturer had issues with inconsistent transmission quality causing unwanted noise and vibration. Sciemetric’s proven NVH test was seamlessly integrated onto their existing EOL test to detect issues such as, valve noise, missing bearings, timing problems, gear and loose rubbing parts in addition to having all data stored in a central location for complete traceability.

Tags:Application Note | Piston Cooling Nozzle Assembly: Test Verification Using Signature Analysis
Sciemetric’s process monitoring system was used to successfully detect piston cooling nozzle defects early in the assembly process. Detects all missing, blocked or obstructed cooling nozzles, measures high and low pressure and provides real-time ‘PASS’ or ‘FAIL’ results to the operator. Installation of the system resulted in the diesel engine manufacturer, decreasing end-of-line repair costs, customer warranty claims and more. Read the Application Note to learn more.
Tags:Application Note: Verification of Piston Type & Orientation Using Laser Scanning
A major automotive integrator was unable to test any one of four engine blocks right after piston insertion and defects being found after final engine assembly were causing expensive teardowns. Sciemetric easily installed a test and analysis system using laser scanning to verify the engine blocks to ensure correct positioning and accurately find defects such as under or oversized and bent pistons.

Tags: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.
Tags:Infographic: Explore the possibilities with in-process test
Many defects are best found in-process and not at the end of the assembly line. To help illustrate these possibilities on your line, the chart below identifies the areas in engine manufacturing where in-process testing can be done and the probability of identifying certain issues within those sections.
Tags:Application Note | Fuel Injector Insertion Verification Using Force Monitoring
Fuel rail defects for a leading automotive manufacturer were traced to the improper insertion of fuel injectors into the fuel rail. The recurring defects were not found until late in assembly and represented a potential warranty issue as the injectors and fuel rails would experience premature wear due to the improper insertion. This risk along with high teardown and repair costs led the manufacturer to look for an efficient, reliable and effective way to monitor the simultaneous insertion of the three fuel rail injectors into the fuel rail. Read the Application Note to learn how Sciemetric fixed the problem.
Tags:Application Note: Engine Vibration Testing
A major engine manufacturer was very concerned about the inconsistent quality of their shipped engines and the issues with unwanted noise and vibration, which often affect customer satisfaction. Traditional subjective testing failed to identify defects, which were eventually discovered at vehicle assembly plants or by customers. This led to expensive warranty repairs and productivity disruptions. The manufacturer required a solution with minimal tooling and fixturing modification that would reliably improve engine quality without affecting yield. read the Application Note to learn how Sciemetric solved their problem.
Tags: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.
