Test History
RH7 technology has undergone a significant amount of testing at nationally recognized commercial and academic laboratories. In addition to laboratory testing, we have over 500,000 miles of on-going road tests on class 2, 4 & 8 vehicles.
- 2010-2012 - Advanced research at The University of Kansas Departments of Mechanical Engineering and Civil, Environmental and Architectural Engineering using a single cylinder engine.
- 2009 - Chassis dynamometer torque horsepower test.
- 2008 - Olson-EcoLogic Engine Testing Laboratories, Fullerton, CA.
- 2007 - Environmental Test Corporation, Aurora, CO.
The University of Kansas
Initial testing performed during Fall 2010 illustrates that as the RH7 device is turned on, approximately a 2% improvement in fuel economy (as indicated by the brake specific fuel consumption) is found utilizing a Yanmar L100V generator as measured by a MicroMotion Coriolis flow meter at 25% load. Moreover, results demonstrate that collected Particulate Matter decreases on the order of 50% as measured by a Dekati Low Pressure Impactor. During these tests, the average power use of the RH7 device was 72.6 Watts (measured by a CR Magnetics CR5220-50 DC current transducer and a CR Magnetics CR5320-30 DC voltage transducer).
Brake Specific Fuel Consumption
BSFC results were similarly dramatic, demonstrating a mean 2.6% reduction in fuel consumption, measured under consistent steady-state conditions, at varying loads (0-100% load in 25% increments). Note that the Yanmar test engine was operated at rated speed (3,600 rpm) for this test. In the interest of concision, the 25% load results are shown below.
Further testing is underway in Spring 2011 with additional focus on the performance of the RH7 device. A more granular analysis of the emissions reductions by THC, NO, NO2 is being completed.
A future project allowing an even more advanced analysis of the combustion process is anticipated during the remainder of 2011. This will include in-cylinder pressure traces, thermodynamic analysis, FTIR and GC/MS analysis of output gases.
Additional test results and details may be made available under non-disclosure.
Chassis Dynamometer, Overkill Street Performance and Racing, Lawrence, KS
A 2006 Chevrolet Duramax powered truck that had been operating with the RH7 device for 27,000 miles was tested on a chassis dynamometer located in Lawrence Kansas. The dynamometer used was a Dynojet friction loaded model. Power sweeps were performed in a series of tests without the RH7 unit energized and with it energized. The maximum torque levels measured are shown in the table.
| Test # | Max Torque (ft-lbs) | Boost (psi) | On/Off | Improvement |
|---|---|---|---|---|
| Test 1 | 700 | 17 | Off | |
| Test 2 | 730 | 17.4 | On | 4.3% |
| Test 3 | 670 | 18.4 | Off | |
| Test 4 | 694 | 17.8 | On | 3.6% |
| Test 5 | 634 | 18 | Off | |
| Test 6 | 652 | 18 | On | 2.8% |
For these tests, manifold boost pressure at maximum torque was also recorded to verify that any performance improvement recorded could not be attributed to changes in boost pressure rather than by using the RH7 device. The table shows that the maximum torque was a strong function of the cumulative heating effects on the engine and intercooler. To be conservative, the tests were performed without power to the RH7 device first. Therefore, the performance improvements shown must be attributed to the RH7 device.
Mark Shackelford, Owner of Overkill Street Performance and Racing wrote: "We dyno'd their Chevrolet truck with the 6.6 liter Duramax engine. I own one of these trucks myself so I am familiar with the rear wheel horsepower numbers that particular vehicle should average with modification and without. On successive dyno pulls with the unit on, and then off, there were noticeable gains in power production. We made another series of pulls to measure boost vs. power gains with the unit on and off. With the unit on, power was increased with no measurable gain in boost pressure. There was also a drop in the amount of "black smoke" coming out of the tailpipe when the unit was activated also. Subsequently we dyno tested their Chevrolet truck with the 6.0 liter naturally aspirated gasoline engine. This truck also saw definite power gains with the unit on."

Don Olson, President of Olson-EcoLogic Engine Testing Laboratories wrote: "Radiant Halo Seven™ is a technology device we have tested in our laboratory with significant reduction of particulate matter without changing fuel or complementing with other devices. Preliminary tests conducted at Olson-EcoLogic Engine Testing Laboratories demonstrated average particulate matter (PM) reductions of 25% and peak reductions were noted of up to 45%. There is interest in the market place to supplement or replace today's diesel particulate filter technology due to cost, effectiveness or other problems associated with that application."
