ANAHEIM, Calif. — Isuzu Trucks has announced the latest addition to their N-Series diesel trucks – the NPR-XD.

The NPR-XD bridges the gap between the NPR-HD (with a gross vehicle weight rating of 14,500-lb) and the NQR (17,950-lb GVWR) with a weight rating of 16,000-lb.

“This new diesel model meets a number of vocational applications and requirements that previously might have required moving from an NPR-HD up to the NQR,” said Shaun Skinner, executive vice-president and general manager of Isuzu Commercial Truck of America. “Now, the NPR-XD offers more payload capacity at an even more competitive price.”

The new NPR-XD standard cab will be available in the 109-, 132.5-, 150 -and 176-inch wheelbases. The crew cab will be available in 150- and 176-inch wheelbases. Every NPR-XD is powered by the Isuzu 4HK1-TC 5.2-litre diesel engine and with a six-speed automatic transmission the powerplant gives 215 horsepower.

Mazda To Delay SKYACTIV-D Clean Diesel Launch In North America

AUTOSERVICEWORLD.COM


Mazda Canada Inc. has announced that the launch of its SKYACTIV-D clean diesel engine in North America is being further delayed from its Spring 2014 announced debut timing.

While Mazda understands its SKYACTIV-D can meet emission regulation requirements without the use of a NOx after-treatment system, it has decided that further development is required to deliver the right balance between fuel economy and Mazda-appropriate driving performance.

Further information on the program, including a timeline of launch for North America, technical specifications and fuel economy will be available at a later date, closer to launch.

Turbocharger’s future in North America

North America‘s turbo ‘revolution’

The change in the market in North America – led by Ford – is particularly remarkable; in 2008, there were no turbocharged petrol engines made in North America, all previous turbo-fitted engines having been imported. The first North American built turbocharged petrol engine was fitted to the Lincoln MKS which used the first North American EcoBoost engine. This engine has since been fitted to the Ford Flex, Explorer and most significantly the F-series pick-up trucks.

“GM has been somewhat behind Ford in terms of the fitment of turbochargers, but it is slowly going down the same route,” said Ian Henry. “It has already started on this journey – the 2012 Cadillac XTS had a turbo option on the 3.6 litre V6 engine. GM is however also working on improving the fuel efficiency of its naturally aspirated engines and has claimed that it can achieve similar fuel efficiencies gains to those available with turbochargers through other means.”

“The impetus at Chrysler will come from Fiat’s MultiAir programme,” adds Henry.

The CAFE rules announced in 2012 will force GM and Chrysler to accelerate their use of fuel saving technologies such as turbochargers and a large part of the increased volumes which will be seen in the next few years and into the 2020s come from the widening take-up across these VMs, Ford having led the way.

According to just-auto’s QUBE data, North America currently has a turbo fitment rate below 20% but by the late 2020s, if not before, its fitment rate will be much closer to that of Europe, at close to 75%.

Fuel Pump Failures Under Scrutiny

Volkswagen and Audi TDIs are under investigation for fuel pump failures. The NHTSA opened the investigation in February 2011 on the 2009 and 2010 Golf and Jetta models. The issues seem to center around contaminated fuel and the high pressure fuel pump not being capable of dealing with diesel that’s been contaminated by gasoline either by the customer or the fueling station.

BorgWarner EFR Turbocharger Technical Training Guide

Brock Fraser is the Chief Engineer & Team Leader of the EFR project for BorgWarner Turbo Systems. In his forward to the EFR Turbocharger Technical Training Guide, Mr. Fraser describes the project vision and the process of development. Below is an excerpt from the guide Forward by Brock Fraser

“The first thing worth explaining is the strong connection between this exciting line of aftermarket turbos and our OEM commercial vehicle products. Commercial/industrial turbo products have extreme requirements for durability, reliability, and aerodynamics performance. Turbo sizing for the performance user more resembles what’s in the commercial realm as compared to what comes from our OE passenger car developments. Also required is resistance to abusive thrust loads, vibration, and robustness for a wide range of lubrication and cooling conditions. Our OE product validation standards are very tough, and many of these same practices were employed during the development of the EFR products.

Maintaining Diesels

  You don’t have to go far to find a fleet having trouble with engines. Mostly they report emissions systems problems, not surprising given the short time the engine makers had to meet the Environmental Protection Agency’s tight timelines.

Honeywell’s 2-Cylinder Diesel Engine

A new chapter in the story of ultra-fuel efficient auto design opened in 2011 with the development of the world’s first 2-cylinder turbocharged diesel engine.

Today, the 0.8L engine, boosted by Honeywell’s smallest-ever turbo, can be seen powering vehicles through the busy streets of India’s cities and towns, typically carrying goods from warehouses to local businesses. For Honeywell, boosting such a small engine created a whole new set of design and engineering challenges.

“The issues in developing a turbo for a 2-cylinder engine not only revolve around packaging but also around specific challenges linked to compressor surge, oil leakage, high vibrations and high thrust load due to engine pulsations. These issues are far more pronounced here than in a four-cylinder engine,” says Vijayan Asvathanarayanan, Director of Application Engineering for Honeywell Turbo Technologies in India.

This meant that Honeywell engineers had to approach the turbo design from a completely new angle.

“We came up with a totally new turbocharger that included a very small turbine housing with integrated manifold, and the smallest-ever compressor wheel developed by Honeywell. The higher relative thrust loads brought about by the pulsation of a bi-cylinder engine meant creating new concept thrust pads in the Z-bearing – vital if we were to be efficient in matching the turbo to the engine requirements.”

A high-efficiency, compact bearing was developed – and the design was so successful that it is now being extended to other turbo sizes as well.

The result of this intense engineering activity is a well-performing and reliable turbo fitted in the 2-cylinder OEM production engine since 2011, which is contributing to a remarkable 25% improvement in power over a non-turbo equivalent and to significant fuel efficiency gains and lower emissions.

Critically, the proven success paves the way for the roll-out of a new generation of turbocharged 2- and 3-cylinder diesel passenger cars and light commercial vehicles, particularly in emerging regions.
