Clean diesel technology paying off: Report

WASHINGTON, D.C. -- EPA10 generation engines now make up 11% of all heavy truck registrations in the US, and have reduced fuel consumption by as much as 560 million gallons while keeping 5.7 million tonnes of CO2 from entering the atmosphere.


WASHINGTON, D.C. — EPA10 generation engines now make up 11% of all heavy truck registrations in the US, and have reduced fuel consumption by as much as 560 million gallons while keeping 5.7 million tonnes of CO2 from entering the atmosphere.

Those were the findings of the Diesel Technology Forum, which shared its results with the California Energy Commission.

“The real-world 3-4% fuel savings of new 2010 and later model year clean diesel heavy-duty trucks is significant for several reasons, because of the energy intensity of heavy-duty vehicles and because diesel engines are the technology of choice for over 90% of commercial trucks,” said Allen Schaeffer, executive director of the Diesel Technology Forum. “Achieving these present gains in fuel efficiency while maintaining near-zero emissions is particularly notable, because these are competing forces.  Heavy-duty truck and engine makers are also working toward meeting first-ever GHG and fuel economy mandates from EPA and NHTSA beginning in 2014 and in 2018.”

Other findings included: More than 20% of the US heavy-duty fleet is using EPA07 or newer generation engines; NOx and PM emissions from heavy trucks have been reduced by more than 95% over the past 25 years; between 2006 and 2012, a million tonnes of NOx and 27,000 tonnes of particulate matter have been eliminated; and the fuel savings from EPA10 engines equate to an average of US$3,500 per truck each year.

    We run Cummins engines in our trucks. Lots of problems with DEF. When we do a DEF delete kit on a truck we get 20% – 25% better fuel mileage. Where is the Diesel Tech Forum getting their figures from?

    You tell em John! My 6 litre ford gets 14 mpg compared to my 7.3 litre ford which gave 22 mpg. where’s the saving there. My 6 litre is due for injectors before 200,000 Kilo’s My 7.3 still does not require injectors at 3 times the mileage. All this emission stuff is causing horrendous problems for the industry. Our town buses are spending as much time in the shop as on the road. How is all this EPA mandated crap helping us?

    Mother nature, Volcanoes put more co2 into the atmosphere than all the trucks in North America. What is the EPA doing to control that? global warming is natural for this planet as we have had many ice ages, tropical ages and this will continue no matter what we do. What do you say EPA?

    that’s what I thought, no response!
