BorgWarner said it was supplying engine timing chain drive systems for Guangzhou Automobile Group Motor (GAC Motor)'s Trumpchi brand's GS4 SUV turbocharged 1.5-litre petrol engine.
"Designed to reduce mass and friction for improved fuel economy, performance and engine efficiency, [our] next-generation inverted tooth silent chain helps GAC Motor meet current market demands," the supplier said in a statement. It claims this latest timing chain technology offers "best in class strength and durability as well as minimum noise, vibration and harshness".
It is produced in China for the first time.
Engineered to withstand high temperatures and tough operating conditions, the T111 inverted tooth silent chain has super finish aperture (SFA) links for improved durability. In addition to an improved link and chain design, the silent chain features a hard-coated pin technology that enhances wear performance for severe environments compared with traditional pin coatings. Due to its high robustness, the silent chain for turbocharged engines offers improved durability and optimised resistance to chain elongation.
