BorgWarner powers direct injection petrol engine

BorgWarner has provided
turbocharging technology to Hyundai’s new petrol direction engine

After announcing that it
would provide turbocharging technologies to Jaguar Land Rover’s (JLR’s) new
family of four-cylinder gasoline and diesel engines, expected to launch in
2015, BorgWarner has announced that its turbocharger powers Hyundai’s new
1.6-litre turbocharged gasoline direct injection (T-GDI) engine. This engine,
with a 205bhp power output, will be available in the US model Veloster turbo
passenger car.

Helping achieve a fuel
efficient and responsive engine for an exhilarating driving experience
combining Hyundai’s direct-injection technology, and BorgWarner’s turbocharging
expertise, Frederic Lissalde, President and General Manager, BorgWarner Turbo
Systems, mentioned that they are pleased with the results. 

While BorgWarner plans to
expand its existing turbocharger manufacturing facility an build a new
engineering centre at Bradford in UK to support JLR’s new engine manufacturing
centre near Wolverhampton, the engine development at Hyundai involved matching
BorgWarner’s K03 twin scroll turbocharging technology with its GDI system.
Compared with a single scroll turbocharger, twin scroll turbocharging recovers
more energy from the exhaust gas and improves responsiveness even at low rpm.
BorgWarner’s twin scroll turbocharger separates the exhaust gases of the
cylinders and minimizes parasitic back pressures.

BorgWarner has further
optimized the exhaust gas flow to the turbine wheel with an optimized channel
design. Thus, torque of 270Nm produced by the Hyundai engine is available over
a wide engine speed range, from as low as 1,750 rpm and up to 4,500 rpm. In
addition, BorgWarner integrated the exhaust manifold into the stainless steel
turbine housing to reduce size and weight while optimizing heat energy recovery
for better efficiency.

Automakers are increasingly
taking to the use of turbochargers in an effort to down size. While Volkswagen
and Ford have taken the initiative to launch turbocharged GDI (petrol) engines in India, more automakers are expected to launch
their versions of turbo-GDI engines. Acceptance for turbo-charged common-rail
fuel injection diesel engine is also rising in India.
