BorgWarner supplies R2S® turbocharging technology for VW 2.0-liter diesel engine
November 18, 2010 by John Day
BorgWarner’s regulated two-stage (R2S®) turbocharging technology boosts the performance and helps lower emissions for the 2.0-liter four-cylinder common-rail diesel engine featured in Volkswagen’s 180 HP (132 kW) Transporter T5 and new 163 HP (120 kW) Amarok pickup. Both versions of the engine comply with Euro 5 emission standards and deliver a maximum torque of 400 Nm at 1,500 rpm, giving the engine impressive pulling power. The engine technology achieves fuel consumption of 31 mpg.
Engineers from BorgWarner used two series-connected turbochargers to deliver continuously high boost pressure over the entire engine speed range with excellent torque characteristics, ensuring an exceptionally dynamic response. The R2S technology helps the new engine achieve a power-to-displacement ratio of 66 kW per liter.
BorgWarner supported the development process with 3D flow analysis of the entire turbocharging system to fine-tune the compact dimensions of the system.
