Description: Advanced Power Systems International Inc.
(APSI) 558 Lime Rock Rd. Lakeville, CT. 06039 manufactures the Fitch
Fuel Catalyst System (FFC Device) that may be installed on either
gasoline or diesel fueled engines. The FFC Device is designed
to improve energy efficiency while minimizing impact to the environment.
APSI has selected to perform the Environmental Protection
Agency (EPA) Federal Test Procedure (FTP) CVS-75 to evaluate what
benefits may be achieved by installing the FCD System on a Diesel
fuel vehicle. Tailpipe emission gases to be measured:
Hydrocarbons………..(HC)
Carbon Monoxide……(CO)
Nitric Oxide………….(NOx)
Particulate Matter …...(PM)
Carbon Dioxide………(CO2) Miles per
gallon
The vehicle selected: GMC-2500
Model year 2002
6.6 Diesel engine
Vin # F235320
No EGR, No Exhaust Catalytic Converter, No modifications to EMU
software
Fuel used for this test was commercially
purchased low sulfur transportation diesel on board
the vehicle at the time of delivery to VEETS. Fuel specifications: |
API Gravity at 60F – 36.26 |
Sulfur – 0.0291 |
Carbon Weight - 88% |
Specific Heat – 18,600 |
Cetane Index - 47.65 |
|

June 2, 2004 |
Vehicle placed in normal service. |
July 20-21, 2004 |
Vehicle returns to VEETS laboratory.
Three (3) Baseline Test CVS-75
Fitch Device Installed (F750) and idled for three (3) hours |
July 22-23, 2004 |
Three (3) Retrofit Test-CVS-75 |
These procedures were designed to be an A-B-A-B comparison
of the impact of the Fitch Fuel Catalyst. Where A=Baseline test,
and B= Retrofit test. Prior to delivery to VEETS the vehicle
had routine oil and oil filter change and OBD scan performed by
a GMC dealer. The vehicle was determined to be normal operating
condition.
Test Performed at VEETS:
1. CVS-75 were conducted to establish a baseline.
2. Thereafter the vehicle is fitted with the FFC (model F750)
system. The vehicle was started and idled for three (3) hours
to insure exposure of circulated fuel to catalyst in the In Line
unit.
3. Subsequent Retrofit CVS-75 were performed.
4. The baseline and retrofit data are then compared.
