BorgWarner wins JLR gasoline and diesel contracts

BorgWarner is one of a number of leading supplier companies to win business from JaguarLandRover (JLR) for its new Ingenium gasoline and diesel I4 engine programmes.

Borg-Warner is providing its state-of-the-art variable cam timing (VCT) and engine timing systems for JLR's new I4 engine family.

Based on a configurable and flexible architecture to improve both manufacturing efficiency and calibration strategies, the engines deliver high performance, reduced emissions and improved fuel economy.

For reliable variable cam timing, BorgWarner’s compact torsional assist (TA) phaser technology actuates rapidly to result in improved performance, while its latest chain and tensioner technologies deliver lower friction and improve wear resistance.

According to BorgWarner, its advanced technologies are used in all 2-liter four-cylinder diesel engines as well as future gasoline engines that will used to power various models.

“With our contribution to JaguarLandRover’s new I4 gasoline and diesel engine programme, we strengthen our position as a leading supplier of engine timing systems and VCT technologies. It shows too that we support global automakers using flexible and modular platforms,” said Joe Fadool, president and general manager, BorgWarner Morse TEC.

“BorgWarner is very proud to expand its successful partnership with JLR, providing our advanced variable cam timing and engine timing technologies to reduce friction and improve engine efficiency,” he added.

To support JLR’s powertrain and calibration strategies for reduced internal friction and vehicle complexity, BorgWarner’s compact TA phaser technology and variable force solenoid (VFS) use available torsion energy in addition to the engine oil pressure to achieve a faster phaser actuation rate.

The technology reduces oil demand and engine parasitic losses, and improves low-end engine performance. BorgWarner’s TA phaser technology is said to achieve 70° of crank rotation or more, and features an integrated centre bolt, resulting in a compact design for easier integration into the powertrain.

Designed to reduce friction while delivering lower noise performance, BorgWarner’s engine timing system features an advanced chain with high-quality finished rounded chain link profiles and pins for improved efficiency, performance and durability.

Also, hydraulic tensioners are tuned using BorgWarner’s patented “tortuous path” vent disk technology to deliver the best balance between efficiency and chain control.
