Subject: Support for the EPA’s Fuel Efficiency Increase. The EPA Reduces the NOx standard for Economy. 

American trucking industry can Save $ 10 Billions of Fuel cost by employing a new 

GreenPowerTM DPF-Hydrated EGR process that does not need ULSD & Urea to reduce PM & 

NOx emissions.

Fuel efficiency is related to global warming gas emission as well-known. Not well-known to the public is, 

however, a thermodynamic theory that fuel efficiency is also related to the NOx emission level for 

heavy-duty diesel engine combustion system. Therefore, any discussion of fuel efficiency can not be 

defined until a new NOx level regulation is optimized for fuel-efficiency, environmental benefits, and economy. 

I would support the Administration’s fuel efficiency increase target of 15% for diesel engine and 10% for gasoline 

vehicle. This can be achieved perhaps by employing a new process of GreenPowerTM system patented in 2009 in 

the USA, an Award Winning Technology for marine diesel engines. The fuel saving by more than 10% is 

possible because the patented process utilizes a waste heat from the muffler.

The 2007 PM-NOx Emission Standard (not 2010 NOx standard) as our national target:

American trucking/automotive/oil industries have achieved a remarkable progress toward clean emission 

as shown in the chart. Today’s (2007) trucks are much cleaner: in PM reduction by 98% and NOx reduction by 70% 

compared to old trucks ( per the 2007 NOx-PM emissions standard). Up to 98% PM reduction was necessary to 

eliminate the toxic health threat by cancer-causing PM nano-particles, for which a Diesel Particulate Filter 

technology is employed. The DPF technology is now mandated for all heavy duty vehicles in the USA and 

throughout the world. A marine DPF system is also to be employed for Ocean Going Vessels, to reduce both PM 

and NOx emission from ships, for which demonstration program the GreenPowerTM DPF-Hydrated EGR was 

selected as a Grant Award Winner for marine diesel engines from the Port of Los Angeles (POLA).

What level of NOx emission is good for both environment and economy? I propose the EPA 

adopts a new lower NOx reduction regulation to 40% for retrofits and 60% for the OEM’s, while 

keeping the PM reduction level by 90%. In the region of ports of Los Angeles and Long Beach, California, 

where diesel pollution was considered as a serious public-health threat, they have selected the 2007 

PM-NOx emission target as their environmental target. 

Economic Benefit to be realized by the new technology of GreenPowerTM

1) $10 billions Fuel Cost Saving:

American truckers can save fuel cost by $10 billions per year today by using a lower-cost nonULSD fuel, when the GreenPowerTM technology is commercialized to be retrofitted on all diesel 

engine vehicles. It is because GreenPowerTM system does not require “ultra” low-S fuel. It can 

use a 50-ppm-S fuel, for example, which is much cheaper than ULSD by about 8-10% of fuel 

cost. In 2006, in retrospect, a ULSD was mandated as “en-abler” for catalysts to function to 

reduce PM emissions. 

The current practice of ULSD-DPF system was a very expensive national technology 

demonstration program to mandate the DPF system to work to reduce PM emission. Now it is 

the time to reevaluate the technology option and fuel requirement again to reduce the costs.

It is because the catalysts are not the panacea for American truck industry any more. The fuel 

borne catalyst-DPF system is commercialized in Europe, and is an alternative process to the 

conventional catalyst-DPF system and the GreenPower DPF-Hydrated EGR system can reduce 

the system cost further, while using a non-ULSD fuel.

2) Increase Fuel Efficiency by 10+ % by utilizing waste heat to boil water to steam (rather than Urea 

chemical) as well as reducing NOx emission.

Concluding Remarks:

1. The Energy, Environment, and Economy can be benefitted by choosing the optimum level of 

NOx emission.

2. I propose the EPA adopts the 40% NOx level for retrofit and 60% for OEM.

3. The EPA abandons the 2010 NOx regulation.

4. American truckers can Save fuel cost by $10 billions per year by using GreenPowerTM technology 

which requires a non-ULSD, or cheaper fuel without affecting our environment.

5. Help to Commercialize the GreenPowerTM technology, invented in the USA for America’s future.
