ENGINE TECHNOLOGY
Honeywell said it has over a decade of commercial vehicle
experience with ball bearings. The Honeywell ball bearing
system integrates ceramic balls as part of a high-resistance
steel cartridge design, configured for customers according to
the required rotor speed, bearing load and life cycle. The ball
bearing system supports the rotating shaft that connects the
turbine and compressor wheels. Honeywell said that up to 5%
fuel efficiency improvement can be achieved with the ball bear-
ing system in a commercial vehicle application.
Another part of the growth behind the growing use of tur-
bochargers is the move toward fuel efficiency and emissions,
said Paja. “A turbocharger does multiple good things at the
same time,” he said. “It improves fuel efficiency. It reduces
emissions and improves drivability of the engine as it has
more torque. It’s a no-compromise solution, so you don’t have
to trade off one thing for another.”
Honeywell’s latest generation VNT DutyDrive turbocharger
is another advanced technology aimed at the medium- and
heavy-duty commercial vehicle sectors. The VNT DutyDrive
turbochargers are engineered to drive high-pressure exhaust
gas recirculation (EGR) while providing greater fuel efficiency
and engine response.
tasked to withstand these type of conditions, temperature
levels and rotating speed levels.”

The VNT DutyDrive turbo incorporates a Honeywell
patented pressure balance system designed to channel
exhaust gas to both sides of the turbine vanes, equalizing pressure and reducing friction and wear while
enhancing controllability. Its variable nozzle configuration offers optimized performance across a wide range
of engine speeds and loads, Honeywell said.
The turbo includes cambered vanes and a new, more
efficient turbine wheel design, which is engineered to
improve turbine efficiency and fuel consumption while at
the same time enhancing low-speed torque and maximum power capability.
Applications for the VNT DutyDrive range from on-highway trucks to off-highway equipment as well as ag engines,
Honeywell said.
Additional growth for Honeywell’s turbos is expected to
come from emerging markets such as China and India,
Paja said. “It is clear that all the growth is happening in the
emerging markets such as China and India, as China produces roughly 50% of the world’s trucks and its production
of commercial vehicles grew over 40% in 2010,” he said.
“The legislation is lagging behind there about five years.
They are behind a little bit with technology content.
“But those countries are growing at a much faster rate. So
even if the technology is not increasing, the number of trucks
is growing at a very fast pace.”
A pace that Paja said Honeywell will keep up with.
“We are growing quite strongly globally,” he said. “We
have what we need to grow our global footprint. We have
plans in place to expand the growth that is coming in the
next few years.” dp
Honeywell Turbo Technologies has manufacturing plants located
worldwide for global customers of its turbochargers used in the
commercial vehicle, automotive and aerospace markets, including
plants in North America; Mexicali, Mexico (shown here); Brazil;
Asia; Europe; Japan, Korea; China; and India.
