Jaguar Land Rover's New I4 Engine Family Features Advanced Technologies from Borg Warner
AUBURN HILLS, MI: High end engineering solution providers BorgWarner announces Variable Cam Timing (VCT) and engine timing systems for the new I4 engine family from Jaguar Land Rover (JLR). The target here is high performance, higher fuel efficiency and decreased emissions.
For reliable variable cam timing, BorgWarner's compact Torsional Assist (TA) phaser technology activates improved performance, while its latest chain and tensioner technologies reduces friction and improve wear resistance. BorgWarner's technologies can be used in all 2.0-liter four-cylinder diesel engines as well as future gasoline engines used to power various models starting with the new JLR engine family.
"With our contribution to Jaguar Land Rover's new I4 gasoline and diesel engine program, we strengthen our position as a leading supplier of engine timing systems and VCT technologies and support global automakers using flexible and modular platforms," says Joe Fadool, President and General Manager, BorgWarner Morse TEC.
To support Jaguar Land Rover'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 for a faster actuation rate of the phaser. The technology reduces oil demand and engine parasitic losses, and improves low-end engine performance. It also achieves approximately 70 degrees of crank rotation, and features an integrated center 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 finishing of rounded chain link profiles and pins for improved efficiency performance and durability. Additionally, hydraulic tensioners are tuned using BorgWarner's patented "tortuous path" vent disk technology to deliver the best balance between efficiency and chain control.
