DYNAMOMETER TESTING

In September, 2001, dynamometer testing was conducted at Taylor Diesel in Hamilton, Ontario, a certified Cummins repair/testing facility. The test vehicle was a T2000 with a Cummins 600 Signature engine, rated as the most technologically advanced diesel engine currently available for use in the heavy truck industry. The truck is equipped with a bypass system so that it can be operated with fuel running directly to the engine, or passing through the Fueltec.

The truck was tested first with the Fueltec, then with the unit bypassed. Filters were changed to ensure any charged fuel was eliminated.

The dynamometer was used for performance testing, while a state-of-the-art, world-recognized Bosch continuous sample analyzer was used for particulate measurement (black smoke that is the major cause of smog and haze). The continuous sample analyzer gives reading under full dynamometer load, unlike rev-up sniffer tests conducted at most emissions test facilities.

Without Fueltec, the emissions readings ranged between 1.2 and 4.8, with an average running about 1.8.

With the Fueltec, the highest number recorded was 0.8, with the average result running at 0.12, ten times better than results while operating without the unit.

Dynamometer test results are summarized in the following charts.
All results were recorded in 17th gear.

In Summary:
At full throttle, no gains were made in either torque or horsepower.
At 3/4 throttle (upper shift speed) small gains were made in both.
At 5/8 throttle (cruising speed) significant gains of 12 percent were made.
In the lower rpm range, huge amounts (more than 40 percent improvement) in power are made.

The T2000 (on the same day) showed a Trip Drive Fuel Economy at 7.953 mpg and the Trip Average Fuel Economy at 7.695 mpg. The average for the T2000 over the last 30,000 miles has been 7.56 mpg. According to Cummins, results for a typical Signature engine averages 6.2 to 6.7 mpg.
