BorgWarner launches new low-friction engine timing chain; 0.3-0.6% improvement in fuel economy

29 January 2014

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 new 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.

As automakers began downsizing engines to improve fuel economy, BorgWarner recognized opportunities to help further improve engine efficiency by reducing power-wasting friction in the engine timing system. BorgWarner has developed a new, smaller-pitch engine timing chain that reduces friction while delivering lower noise and improved durability for these tough engine environments.

—Joe Fadool, President and General Manager, BorgWarner Morse TEC

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 (electro-polishing, an electrochemical process to remove material from a metal) improves surface finish to reduce friction.
