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.

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.

Engine manufacturers require a reliable and cost-effective end-of-line test to catch any defects missed during engine assembly. Hot testing, with its long cycle times and requirements for dedicated resources and facilities for stations, is expensive. Read our Application Note to learn about Sciemetric's solution.

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.

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.
