BorgWarner's next-generation 6.35 mm inverted tooth silent engine timing chains are launching on engines from Mitsubishi, Suzuki, Hyundai, General Motors Korea and one Chinese automaker. The innovative engine timing chain is designed to reduce friction, resulting in as much as 0.3% to 0.6% improvement in fuel economy based on customer testing. BorgWarner will produce the new low-friction engine timing chains for a variety of 0.66- to 2.0-liter gasoline engines for vehicles in Japan, China and Korea.

BorgWarner's low-friction engine timing chain combines inverted tooth silent chain technology with an optimized link back shape. Compared with conventional technology, the optimized link back shape reduces contact area and friction as the chain slides along the arms and guides, where most friction losses occur. In addition, super finish apertures enhance wear and efficiency performance, and "E" polishing improves surface finish to reduce friction.
