In The Light-Duty Truck Sector – Deionization Water Systems

On July 18, the EPA, the Department of Transportation’s National Highway Transportation Safety Administration and the California Air Resources Board issued a joint Draft Technical Assessment Report, a midterm national evaluation program for greenhouse gas emissions and fuel economy standards for light duty cars and trucks.

The Draft TAR, which covers vehicle model years 2022-’25, confirms that automakers are introducing new technology to market at a fast clip, and predicts that the model year 2022-’25 standards are attainable with a wide range of technologies.

In a press release issued by the Diesel Technology Forum, the organization’s executive director Allen Schaeffer said, We’re extremely pleased that EPA, DOT and CARB recognize at this time especially the greenhouse gas emissions improvements in new and future clean diesel technology and fuels.

Automakers and engine manufacturers have invested billions of dollars in diesel research and development to significantly improve the fuel efficiency and emissions from modern diesel vehicles. While the Draft TAR specifically highlights advanced gasoline vehicles as being the primary source for achieving future fuel efficiency levels, we believe that new clean diesel engines will also play a key role in reaching the 2025 mileage goals.


Whenever Achieving the increased fuel economy standards is will be difficult, Schaeffer added that.

This is a tremendous challenge for the industry. Dayclean diesel carsaverage about 30 percent better fuel economy than their gasoline counterparts. You see, as additional ‘high mileage’ clean diesel cars and pickup trucks are introduced in the we anticipate the diesel market to increase as will diesel’s role in helping achieve the future fuel efficiency standards. Certainly, in the lightduty truck sector, new clean diesel pickups are achieving higher mpg levels and for the first time a diesel pickup truck has reached the 30 mpg highway level.

increased turbocharger boosting and engine downsizing; engine downspeeding; advanced use cooled EGR systems; the improved integration of charge air cooling into the air intake system; and the improved integration of exhaust emissions control systems for criteria pollutant control, The Draft TAR states that diesel engines are continuing to evolve using technologies similar to those being introduced in new ‘lightduty’ gasoline engines and heavyduty diesel truck engines, including advanced use friction reduction measures. Whenever in line with the draft TAR, p brake thermal efficiency a measure of energy efficiency of advanced diesel engines under development for ‘light duty’ applications is now 46 percent and is approaching that of heavyduty diesel truck engines.

Essentially, in contrast, gasoline engines day achieve around 37 percent.
