German premium manufacturer,
Mercedes-Benz will now use a global product leader in clean and efficient
technology solutions- BorgWarner’s regulated two-stage (R2S®) turbocharging
system. This solution will boost the most powerful version of Mercedes-Benz 4-cylinder
diesel engine, the OM 654, with a power of 180 kW (241 HP).
The design of BorgWarner’s turbocharging
system was especially adapted to comply with the stringent current emissions
standard Euro 6d TEMP, while delivering outstanding engine performance.
Hitherto, the R2S utilises an intelligent combination of highly sophisticated
variable turbine geometry (VTG) turbocharger for high-pressure stages and a
wastegate turbocharger for low-pressure stages.
Joe Fadool, President & General
Manager, BorgWarner Turbo Systems said, “With its innovative technologies,
BorgWarner is supporting automakers to meet tough emissions standards.
Developing more environmentally friendly vehicles is part of our larger vision
for a cleaner, more energy-efficient world. At BorgWarner, we are proud to
continue our successful long-term cooperation with Mercedes-Benz. Our
highly-efficient R2S turbocharging technology enables a cleaner diesel engine
to achieve the best possible performance.”
BorgWarner’s R2S system enables optimised
air supply over the whole engine map, which results in best possible fuel
consumption and low emissions by supplying the required boost for optimum
combustion. The new turbocharging system takes care that Mercedes-Benz OM 654,
which offers a smaller displacement of just under two liters compared to its
forerunner, still delivers 20 per cent higher power output.
