Peering more perfectly into piston precision
WHAT: LED light check of cooling gallery of high-performance pistons
INNOVATION: Tenneco has developed an automated test method that ensures the cooling gallery of pistons is sound, which is critical to maintaining piston temperatures ideal for fuel consumption. The method sends LED light into the gallery, where a photocell operates as a receiver to measure the amount of light emitted, helping to reduce cost and scrap levels incurred in traditional testing procedures.
