The gap between official and real-world fuel-economy figures in Europe has risen to about 38%, according to a new report published by the International Council on Clean Transportation (ICCT). This procedure was developed in the 1980s and was not originally intended to be used for fuel consumption testing but air pollutants.
Specifically, in this action, NHTSA is affirming that its statutory authority to set nationally applicable fueleconomy standards under the express preemption provisions of the Energy Policy and Conservation Act (EPCA) dictates that such state and local programs are preempted. criteria pollutants—is not affected by the action.
Cash for Clunkers”) program could maximize greenhouse gas emissions savings by using fuel-economy based eligibility requirements rather than age-based requirements. A minimum age restriction will inadvertently exclude newer, low fueleconomy vehicles from participation in the program. Allan et al.

Earlier post.). Reducing barriers to investment in energy efficiency.
Traffic is a major source of harmful pollutants; daily peak exposures tend to occur near roadways or while traveling—or being stuck—on them. That gave them rare, real-world look at pollutant exposure. With windows closed, the pollutants took longer to enter the vehicle cabin, but also longer to exit it.
The air-fuel mix is consequently optimized and this reduces fuel consumption, while also minimizing the emission of CO 2 and other pollutants (nitrogen oxides and particulates) at all engine speeds. When the flap is in the closed position, gas flows unhindered through the ports that remain open and increases turbulence.
The high-level performance goals of the Partnership are a 25-40% improvement in fueleconomy in a light-duty vehicle (LDV) and achieving 55% brake thermal efficiency (BTE) in heavy-duty engine systems. bio-derived) fuels have the potential to dramatically increase fueleconomy. The potential is significant.
The test fleet showed statistically significant effects for some pollutants, but not for others. NO x emissions, a target pollutant of concern for this program, did not show any statistically significant difference between the fuels for the FTP nor for each individual FTP phase.

The defect leads to lower fueleconomy, non EPA-compliant emissions levels, and costly and frequent vehicle repairs, the complaint charges. When the SCR system breaks down, the filter gets clogged, requiring more fuel to be injected to burn it off, according to the complaint.
One of the main groups of pollutants resulting from fuel combustion is the oxides of nitrogen, or NO x. Future fueleconomy standards will result in lower exhaust gas temperatures and limit the use of high-temperature SCR.
But how can you increase your fueleconomy? Surprisingly, the number of items you carry in your vehicle can have a meaningful impact on your fueleconomy. While it does cost a bit to have your car checked over by a mechanic, regular maintenance will improve your fueleconomy and help you catch problems before they occur.

One of the best ways to do that is by maximizing your fueleconomy. Below, you will find some of the best ways to improve the fueleconomy of your hybrid right now so you can save even more money with an already economical vehicle. These tricks will work equally well with plug-in hybrids and traditional hybrids.

The fueleconomy and power output of the engine is superior when compared to CNG’s, [S S Thipse, the lab’s senior assistant director] added.
The fuel paths may perform differently by region because energy-use characteristics differ significantly by region. On a national average, EVs and CNGVs can reduce fuel-cycle GHG emissions per kilometer traveled by 20% and 6%, relative to ICEVs. Fuel-cycle NO x and SO 2 emissions of EVs, CNGVs, gasoline ICEVs, and HEVs.

Fleets have increasingly converted to aluminum wheels that offset the weight of necessary pollution-control equipment used to meet federal emissions regulations. Lighter wheels also improve fueleconomy. Alcoa’s wheels business has been launching a progression of innovations since inventing the forged aluminum wheel in 1948.
Car buyers shouldn’t be forced to buy high-end bells and whistles when fueleconomy and reducing emissions are their top priority. It emits 44% less global warming pollution than its closest conventional counterpart, the Toyota Matrix, and its hybrid drivetrain costs a little more than $3,000.
Administrator Pruitt also announced the start of a joint process with the National Highway Traffic Safety Administration (NHTSA) to develop a notice and comment rulemaking to set revised GHG emissions standards and Corporate Average FuelEconomy (CAFE) standards. The Obama Administration’s determination was wrong.

More than half (57%) of respondents who said they intend to purchase a SUV said they want its fueleconomy to be at least 25 mpg (9.4
Gasoline direct-injection (GDI) engines have higher fueleconomy compared to the more widely used port fuel injection (PFI) engines. Among the findings from the study: For vehicles certified to the same emissions standard, there is no statistical difference of regulated gas-phase pollutant emissions between PFIs and GDIs.
Current fueleconomy policy clearly demonstrates this fact. —“The Case for Technology Neutral Public Policy in FuelEconomy Debate”. The quickest and most cost-effective way to achieve our energy usage goals is through faster adoption of fuel-efficient downsized gasoline and diesel engines.
JILA physicists and colleagues have identified a long-missing piece in the puzzle of exactly how fossil fuel combustion contributes to air pollution and a warming climate. By finally understanding the reaction in full, we can model the atmospheric chemical processes much more accurately, including how air pollution forms.
