AUBURN HILLS, Mich.,
Sept. 13, 2018 /PRNewswire/ --
Ever-stringent emissions regulations as well as rising fuel prices
call for innovative solutions – such as BorgWarner's Organic
Rankine Cycle (ORC) waste heat recovery system, which is new to the
commercial vehicle sector. In conventional applications, almost 50
percent of the engine's fuel energy is rejected to the environment
as heat. ORC waste heat recovery presents one of the most effective
solutions to this challenge. BorgWarner produces and develops a
complete system, consisting of tailpipe and EGR evaporators, an
exhaust flap bypass valve, a turbine expander as well as turbine
expander power electronics and a condenser. Thus, the company
provides its customers with an advanced solution which reduces
CO2 emissions, improves fuel economy by 3 to 5 percent
and supports mild hybrid commercial vehicles.

"At BorgWarner, we constantly aim to drive the latest
advancements in efficient mobility," said Joe Fadool, President and General Manager,
BorgWarner Emissions & Thermal Systems. "By converting wasted
exhaust heat into usable electrical energy, we support our
customers and protect the environment at the same time."
BorgWarner's ORC waste heat recovery system generates electrical
energy by converting energy from the fuel that would be typically
wasted as heat. The system takes advantage of the phase change
characteristics of fluids similar to air conditioning or
refrigeration systems. The cycle can be divided into four steps.
First, the cool working fluid from the condenser is pumped to high
pressure. Then, waste heat from the engine heats the working fluid
to a superheated vapor, which in turn drives the turbine expander
and generates electrical power. Finally, the low-pressure vapor is
cooled back to a liquid state by the condenser, and the process
repeats itself.
Featuring a 48-volt electrical output, BorgWarner's innovative
ORC turbine expander is not only well-suited for combustion
vehicles but supports mild hybrid commercial vehicles, an emerging
trend expected for the next five to ten years. Its oil-free bearing
system and aerospace-inspired turbine allow for best-in-class
efficiency. BorgWarner's evaporators enable improved balance
between durability and high performance through an unparalleled
design and manufacturing process. The exhaust bypass valve provides
a valuable method for controlling the amount of heat entering the
waste heat recovery system from the tailpipe exhaust system. At
high engine loads, it is sometimes necessary to bypass the tailpipe
evaporator. The company's exhaust bypass valve provides a
proportional flow control of the exhaust and ensures low
backpressure to maximize engine performance. The ORC waste heat
recovery system strengthens BorgWarner's position as a global
leader in clean and efficient propulsion systems.
