Study: New Diesel Truck and Bus Engines Emissions Dramatically Cleaner Than Expected

A brand new study says the reduction in emissions in the newest clean-diesel motors has exceeded the amount needed by law.

The study released through the Coordinating Research Council within cooperation with the Health Results Institute highlights the low-emissions performance of the new era of clean diesel technology produced starting in 2010.

It discovered a more than 60% decrease in emissions of nitrogen dioxide as compared to previous 2007 versions, and 99% reduction when compared with 2004 models. The study information that the reductions "exceeded considerably even those levels necessary by law. "

"These results underscore just how clean the brand new generation of fuels, machines and emissions control technologies really is, coming in substantially cleanser than required under the ENVIRONMENTAL PROTECTION AGENCY and California Air Sources Board standards" says Allen Schaeffer, executive director from the Diesel Technology Forum, a business representing the diesel business.

The Coordinating Research Authorities is an organization that guides engineering and environmental research on the interaction between automotive/other mobility equipment and oil products whose partners consist of both government and market.

The Health Effects Institute is definitely an independent research organization which studies science on the wellness effects of air pollution whose beneficiaries include both the federal government as well as vehicle and engine manufacturers.

The Advanced Collaborative Emissions Study is a multi-party five-year research effort to test the actual emissions and health associated with the new technology diesel applications to document the enhancements that have been made and to make sure that there are no unintended emissions from this new technology. This part of the ACES study develops on the findings from Stage 1 completed in 2009 that will found substantially lower amounts of emissions of particulate issue than anticipated. In that case 3 years ago engines were 99% reduced compared to 2004 models.

"Not only are the 2010 sometime later it was model year technology near absolutely no emissions for fine contaminants, this study confirms they are also substantially below the EPA/CARB standard for one of the crucial precursors to ozone development, nitrogen dioxide, " states Schaeffer.

He says these types of findings ultimately translate into thoroughly clean diesel technology delivering substantial clean air benefits for nearby communities.

“There is also excellent confidence in this new creation of clean diesel technology through those that use it every day, ” says Schaeffer “According to the research, today more than 11% of the commercial trucks and also buses on the road are using the particular 2010 or newer technology of clean diesel technology; and much more than one-third are using the year of 2007 and newer technology. ”

He notes not only tend to be these heavy-duty trucks along with buses lower in emissions with regard to particulates and smog developing compounds like nitrogen dioxide as reported today, however they must continue to meet these kinds of near-zero clean air performance requirements for 435, 000 kilometers, almost four times lengthier than required for passenger cars.

"Getting to these near-zero levels of emissions is a result of the highly incorporated clean diesel system, solution ultra low sulfur diesel powered fuel, advanced engine technology and emissions control techniques, " says Schaeffer.

Beginning Jan. 1, 2014, heavy-duty engine and truck producers will offer new models in which comply with the additional new specifications for lower emissions associated with carbon dioxide and minimum gas efficiency levels, as required through EPA and the National Freeway Traffic Safety Administration.

"This clean diesel, clean air achievement story is due to the vast amounts of dollars in investments created by engine manufacturers, fuel providers and emissions control technological innovation companies. While this study is restricted to highway diesel search engines used in commercial trucks in addition to buses, over the last five many years virtually the same requirements, for example cleaner diesel fuel as well as progressively lower emissions criteria, have been phased in for a big portion of new non-road motors, ” Schaeffer says. “This coming year marks among the key emissions milestones coming from some of the larger diesel machines used in off-road machines and also equipment and marine ships and locomotives.
