Navistar’s Spiral of Despair. A Response.
Not a particularly clear one it has to be said, but congratulations to Today’s Trucking for pinning down RW and getting some words from Warrenville. Today’s Trucking, btw, is based in Canada, where SCR appears – says Navistar – to be OK, just so long as you wear a respirator. We digress.

Granted, Wiley’s response has the sort of utility normally associated with a chocolate teapot, but there are some standouts:

In the seemingly endless war of words between the SCR and EGR camps, Navistar has been vocally critical of SCR as a North American emissions solution. But Wiley says such a characterization is ‘unfair’, adding that the company has only ‘discussed’ the use of ‘urea’ in 2010 engines. ‘There’s a big difference’.

This discussion – soon to take place before the Federal Court of Appeals – might be regarded by others as something rather more formal and less relaxed, but litigation is in the eye of the beholder and so on. However, as a real twist, here’s a suggestion that MWM may be producing SCR equipped engines (deemed lethal in the US, and usually employing a substance described as ‘toxic and volatile’ by Navistar) without the need for Urea:

Wiley couldn’t confirm whether Urea – or more accurately the urea-based NOx-busting chemical Diesel Exhaust Fluid (AdBlue in Europe) required in most SCR engines – will be used in the Brazilian NGD engines as well.

Suggesting that not only has Navistar achieved the seemingly impossible, and produced a EGR-based engine that will prove to be compliant and competitive at EPA 10 – in itself a stellar achievement given both that its tenure within the HD market can still be measured in minutes and that many long term market participants – not least the designer of Navistar’s rebadged engine gave up on this sometime ago – but it has also – possibly – produced a SCR engine without recourse to …. er …… SCR.

2009 Chevrolet Silverado Hybrid Out This Year

February 12th, 2008

Last 2007, Chevy sparked the interest of motorists when it came out with its 2009 Chevrolet Silverado Hybrid. As history has shown, hybrid concepts have a tendency to fall off the face of the concept world, never to be heard from again. Not this time. Chevrolet has announced that the eco-friendly 2009 Silverado will be released later this year. Finally, a truck that looks cool and kicks butt at the same time.

For those unaware of what features came with the 2009 Chevrolet Silverado, here’s a rundown of its capabilities. The 2009 Silverado was built with a 6-liter V-8 engine and comes equipped with Active Fuel Management and late-intake valve closing technology.

The truck gives a 40 percent increase in city fuel economy and a 25 percent increase in overall fuel economy allowing the vehicle to go more than 500 miles. The Silverado can also hit 30 miles per hour when running solely on electric mode and depending on the battery charge, the truck can even go up to a full mile. The truck is also capable of towing up to 6,100 lbs and is equipped with the GM’s 2-Mode Hybrid system that optimizes the truck’s transmission allowing it to vary its gear ratios. The Silverado also comes with a front air dam and a tonneau cover for the bed. The truck is not without its drawbacks, however, having only minimal cabin space and having the battery pack placed in the car’s backseat. Despite those two minor setbacks, the 2009 Chevrolet Silverado pretty much makes up for this with its other features Read More
