GREEN ENGINES * USA: TRUCKMAKERS DULY APPLY IT

* New York - GHG Phase 2: The OEMs have stepped up

--- While the truck makers are keeping their some of their plans quiet about the technologies they plan to deploy to meet the anticipated Greenhouse Gas Phase 2 emissions standards, they are not just sitting idly by. 

 ° International said it is “systematically taking weight out” of its platforms. Our Confidence Report on lightweighting found that for every 1,000 lbs. of weight reduction there is a 0.5% to 0.6% fuel economy savings.

 ° Kenworth is making its AeroAdvantage Fairing available as a factory-installed option for its T680 Advantage highway models with 76-in mid-roof sleepers. It is also expanding its auto/start stop system. In addition to preventing fuel gelling, systems like this also reduce idling by turning the main engine on and off as required for heating and cooling while the driver is resting.

 ° Mack is changing compression ratios on its engines to allow for more complete combustion and is offering a two-speed cooling pump. Combined the company said those things will increase fuel economy on its MP7 engine by 5.1% and on its MP8 engine by 5%. For its downspeeding tractor option Mack will offer the MP8 engine with a turbo compounding system that “converts waste energy from the exhaust to mechanical energy that is fed back to the engine.” The result is a fuel efficiency increase of 8.8%

 ° Volvo says it has retooled D11 engine offers a 2.2% fuel economy improvement over 2014 model. In the middle of 2017 Volvo will introduce an engine with turbo compounding and waste heat recovery.
 ... Many of the OEMs talked about their offering electronically controlled transmission choices which not only save fuel, according to our Confidence Report, but also aids with driver recruitment and retention and improve safety...
