Today the focus for commercial vehicle engine boosting is more on the continuous pursuit of fuel efficiency and emissions reduction rather than on outright power…and that’s why Honeywell, with the broadest product portfolio of any turbo manufacturer, is committed more than ever to the greening of the commercial vehicle industry.

“We are witnessing a convergence of global on and off-highway emissions standards, and the result is a drive towards cleaner burning engines that increasingly have to adopt both EGR and Selective Catalytic Reduction (SCR) after treatment devices for lower NOx and particulate matters,” says David Paja, VP of Global Marketing, Honeywell Turbo Technologies. “And this bodes well for advanced turbo technologies that enable such systems.”

This is particularly the case in the on-highway truck segment, where new generation engine designs will incorporate more sophisticated turbocharaged solutions to help achieve the ultra-low NOx levels demanded by US EPA10, Euro6, and Japan 09/10.

In the medium-duty sector, the EGR strategies adopted by OEMs have been favoring more advanced VNT™ turbocharging solutions such as VNT™ DutyDrive, Honeywell’s double axle variable geometry turbine architecture. For longer-haul heavy-duty trucks, SCR strategies are more prevalent. As a result, high-efficiency single-stage systems and two-stage configurations will become more commonplace.

In time, these technologies will augment the current turbo offerings in the emerging regions, led by Brazil, which is scheduled to implement Euro5 by 2012, and followed by China and India, which plan to introduce Euro5 some time later.

Meanwhile, in the off-highway industry, Honeywell provides turbo technologies for an incredibly diverse range of applications – from small agriculture equipment with power ratings starting at 50kW to huge mining trucks developing 2MW. Here too, turbo sophistication will increase to help manufacturers meet regulations such as US Tier4, which demands particulate matter and NOx reductions of around 90% over Tier3 levels.

“Honeywell – with its leading global engineering and manufacturing footprint and its broadest product portfolio – is increasingly seen as a key worldwide technology partner and this position is being translated into new engine program wins on every continent,” says David Paja.

Honeywell’s commitment to the CV sector is exemplified through a multi-million dollar investment program that was sustained even during the global recession.

Around one third of the company’s engineering spend is devoted to CV turbocharging, which benefits from collaboration with the passenger car business while leveraging Honeywell synergy in aerospace, materials science and sensing and control systems.

As a result, the company possesses the best CV R&D resources, the widest product portfolio of any turbo supplier and an engineering network that extends from Torrance in the US to Shanghai in China and Brno in the Czech Republic.

All this is complemented by CV turbo manufacturing facilities in China, India, Romania, Brazil and Mexico – all of which provide customers with product quality, reliability and scalability delivered through the unique Honeywell Operating System.

“Whether it’s on or off-highway, Honeywell has a clear vision to be the segment leader in the foreseeable future,” says David Paja.
