EPA-AA-TEB-81-30 Evaluation of the Super-Mag Fuel Extender By H. Anthony Ashby August 1981 Test and Evaluation Branch Emission Control Technology Division Office of Mobile Source Air Pollution Control Office of Air, Noise, and Radiation U.S. Environmental Protection Agency ------- Background The Environmental Protection Agency receives information about many sys- tems which appear to offer potential for emission reduction or fuel econ- omy improvement compared to conventional engines and vehicles. EPA's Emission Control Technology Division is interested in evaluating all such systems, because of the obvious potential benefits to the nation from the identification of systems that can reduce emissions, improve fuel econ- omy, or both. EPA invites developers of such systems to provide complete technical data on the system's principle of operation, together with available test data on the system. In those cases for which review by EPA technical staff suggests that the available data show promise, or EPA is requested to test the device by other governmental agencies, attempts are made to schedule confirmatory tests at the EPA Motor Vehicle Emission Laboratory (MVEL) at Ann Arbor, Michigan. The results of all such test projects are set forth in a series of Test and Evaluation Branch reports, of which this report is one. In the case of the Super-Mag device, the request for EPA evaluation was made by the Consumer Office of the Metropolitan District Attorney for Denver, Colorado. The testing load at MVEL was such that several months would elapse before the device could be tested there. EPA management therefore decided to conduct the evaluation at the facility of an EPA test contractor, Hamilton Test Systems, in Portland, Oregon. The tests .were directed, and the device installed per manufacturer's instructions, by the on-site EPA Project Officer. The Super-Mag is a retrofit device marketed by Valor Enterprises, Inc. of West Milton, Ohio. It consists of a set of magnets and sheet metal plates that are installed around an automobile's fuel line near the car- buretor in a box-like arrangement. Valor Enter-prises makes no claim in the installation instructions nor in its packaging for increased fuel economy or reduced emissions. On the package label, this statement appears: "Transforms Molecular Properties of Liquid Fuel to Maximum Combustion Efficiency." The conclusions from EPA device evaluations can be considered to be quan- tatively valid only for the specific test vehicles used; however, it is reasonable to extrapolate the results from the EPA evaluation of other vehicles in a directional manner, that is, to suggest that similar results are likely to be achieved on other vehicles. Summary of Results Neither fuel economy nor exhaust emissions were affected by the instal- lation of the Super-Mag device on the cars used in this evaluation. Any differences between baseline test results and results from tests with the device installed were within the range of normal test variability. ------- -3- Device Description The Super-Mag Fuel Extender consists of two magnet assemblies, two steel plates, and two plastic ties. Each magnet assembly consists of a rectan- gular magnet with dimensions of 1.87" X 0.87" X 0.38" bonded to a steel plate 2.67" X 1.14" X 0.04. The two magnet assemblies are placed on opposite sides of the fuel line with the magnets on the inside, about 3 inches from the carburetor. The two steel plates are placed at the edges of the magnet assemblies and at right angles to them to form a sort of 4-sided box, enclosing the fuel line. (See illustrations in Appendix 1, which is a copy of the installation instructions that came with the device.) Test Vehicles Three test vehicles were chosen for this evaluation. The intent was to test a fairly wide range of model years, vehicle sizes, and engine sizes, and to have each major American manufacturer's products represented. The following vehicles were chosen: 1976 Chevrolet Malibu equipped with 350 C1D V-8 engine and automatic transmission. Exhaust emission controls include exhaust gas recir- culation (EGR) and oxidation catalyst. At the beginning of the evaluation, there were 75,810 miles on the car's odometer. 1978 Plymouth Horizon equipped with 105 CID in-line 4-cylinder engine and automatic transmission. Exhaust emission controls include EGR, air pump, and oxidation catalyst. There were 34,210 miles on the car's odometer at the beginning of the evaluation. 1981 Ford Fairmont equipped with 200 CID rn-line 6-cylinder engine and automatic transmission. Exhaust emission controls include EGR, air pump, three-way catalyst, and oxidation catalyst. At the start of the evaluation there were 8,830 miles on the car's odometer. Test Vehicle Descriptions may be found in Appendices 2 through 4. Test Procedures Exhaust emission tests were conducted according to the Federal Test Procedure (FTP) described in the Federal Register of June 28, 1977, and the EPA Highway Fuel Economy Test (HFET) described in the Federal Register of September 10, 1976. The vehicles were not tested for evap- orative emissions. Prior to baseline testing, each vehicle was given a specification check and diagnostic inspection. The ignition timing, idle speed, and fast idle speed were checked for agreement with the manufacturer's specifica- tions given on the Vehicle Emission Control Information label affixed to the engine compartment. The vehicles were also inspected for engine vacuum leaks, proper connection of vacuum hoses, functioning PCV valve, oil and coolant levels, and general condition of engine compartment. ------- -4- Repairs on each vehicle were as follows: 76 Malibu - Steam-cleaned engine, changed engine oil and filter, changed air filter. Replaced spark plugs. Replaced air cleaner hot air duct. Rebuilt carburetor (installed new needle valve, seat, power valve, gaskets, and fuel filter). Adjusted idle air-fuel ratio. 78 Horizon - Changed engine oil and oil filter, changed air filter. Replaced spark plugs. Replaced carburetor, checked choke operation, idle speed, ignition timing, idle air-fuel ratio. 81 Fairmont - No repairs or adjustments were necessary. After repairs, the Malibu and the Horizon were driven on a 100-mile urban/suburban route in the Portland area to condition the engines and stabilize emissions, and then tested on the FTP and HFET. This sequence was repeated on the Malibu to ensure that the emission levels had stab- ilized. Because the Fairmont has just been used in a sequence of several consecutive FTP's, HFET's, and other dynamometer tests, it was felt that the road route driving was not necessary to stabilize its emissions. At least two tests were conducted on each car in each of these configura- tions: baseline, with device installed, and final baseline. After the last emission test an engine diagnostic check was conducted to assure .that the engine state of tune was still at manufacturer's specifications. Results and Discussion Composite FTP mass emissions and fuel economy, and HFET fuel economy, are listed in Table 1 for the 76 Malibu. Data for all seven tests plus averages are shown. The differences in emissions and" fuel economy between the baseline tests and test with the Super-Mag installed are all within normal test variability, with the possible exception of NOx emis- sions. The NOx emissions averaged 1.97 gm/mi in baseline tests, and 2.14 gm/mi with the device installed, an increase of 8.6%. That dif- ference is greater than two times the standard deviation on the baseline results. Normal variations in the operation of the EGR or ignition timing systems on this five-year-old car may be responsible for the dif- ference. Test results on the 78 Horizon are listed in Table 2. The differences in fuel economy and HC emissions between baseline tests and tests with the device installed are within normal tesitng variability. CO and NOx emissions differences between baseline and with-device tests are somewhat larger. CO emissions averaged 15.9 gm/mi on four baseline tests and 14.1 gm/mi on two tests with the device. This is a reduction of 11.3% from baseline. This may appear to be a significant reduction, but the coefficient of variation of baseline CO is 11.9%. Thus, the CO difference is within normal test variability for this car. Average NOx emissions increased from 1.70 gm/mi at baseline to 1.88 gm/mi with the device. The difference is about 1.5 standard deviations of the baseline results and is considered to be within normal test variability for this car. ------- -5- On the 81 Fairmont, essentially two evaluations of the Super-Mag were required because of a step-change in CO emissions during testing. (Fuel economy was unaffected.) As shown in Table 3, baseline CO emissions averaged about 2.7 gm/mi. CO emissions with the device averaged about 3.3 gm/mi, within the range of test variability at such low levels of emissions. However, the post-device baseline tests gave CO emissions of about 6.1 gm/mi. A thorough engine diagnosis and fuel system examination revealed no deviation from manufacturer's specifications. An additional set of two tests confirmed the new baseline CO level of over 6 gm/mi. Those four tests were used as the baseline for another evaluation of the device. The results from these four baseline tests, two tests with device installed, and two more baseline tests after removing the device are listed in Table 3 under the heading "2nd Evaluation". Any dif- ferences in results between baseline tests and those with the Super-Mag are well within normal test variability. Conclusions In tests on three cars representing a range of model years, engine sizes, and chassis layouts, the Super-Mag Fuel Extender had no significant effect on the emissions of any pollutant nor on fuel economy. ------- Mass Emissic Baseline with Device Post-Device Baseline Average of 5 Baseline Tests HC 1.24 1.26 1.3A 1.36 1.27 1.31 1.39 1.31 r JLr r,mj.s>t CO 2A.12 27.06 28.22 30.18 26.91 28.69 30.95 27.81 -6- Table 1 >ns and Fue '6 Malibu sions, gpm- C02 658.0 643.3 632.4 662.9 663.6 653.2 655.7 648.5 1 Economy NOx 2.01 1.86 1.95 2.16 2.12 2.04 1.97 1.97 Fuel Economy, mpg FTP HFET 12.7 12.9 13.0 12.4 12.5 12.6 12.5 12.7 18.0 18.3 18.4 17.6 17.8 18.1 18.0 18.2 Average 2 Tests With Device 1.32 % Change From Baseline + .8% 28.55 +2.7% 663.3 +2.3% 2.14 +8.6% 12.5 -2% 17.7 -2.8% ------- Mass Emissi Baseline with Device Post-Device Baseline Average of 4 Baseline Tests KC .75 .80 .69 .70 .64 .81 .75 r ir jc.rn.LS CO 16.6 16.9 14.9 13.3 13.1 17.1 15.9 7 Table 2 ons and Fue '8 Horizon sions, gpm- C02 332.1 322.6 328.0 325.0 331.9 320.8 326.9 1 Economy NOx 1.73 1.78 1.63 2.17 1.78 1.50 1.70 Fuel Economy, mpg FTP HFET 24.6 25.2 25.1 25.5 25.0 25.3 25.0 34.6 34.4 34.2 34.1 33.8 34.4 34.3 Average 2 Tests With Device .70 14.1 326.5 1.88 25.3 34.2 .% Change From Baseline -6.7% -11.3% -0.1% +10.6% +1.2% -.3% ------- Table 3 Mass Emissions and Fuel Economy 81 Fairmont Baseline Average of 2 Baseline with Device Average 2 Tests With Device % Change .Baseline With Device Post-Device Baseline Average of 6 Baselines Average 2 Tests With Device % Change HC .30 .28 .29 .30 .34 .32 +10.3% .52 .54 .60 .56 .54 .56 .54 .56 .55 .55 0 tir tmiss CO 2.57 2.72 2.65 3.20 3.34 3.27 +19% 2nd 6.12 6.15 6.91 6.47 6.26 6.79 6.58 6.91 6.52 6.53 + .2% ions, gpm C02 513.5 513.3 513.4 510.3 511.8 511.1 -.5% Evaluation 499.7 508.4 517.3 508.8 514.4 508.2 507.0 509.3 508.4 511.3 + .6% NOx .87 .80 .84 .73 .72 .73 -13% .80 '.73 .77 .61 .80 .75 .94 .71 .76 .78 +2 . 6% ruc-L JLC FTP 17.1 17.1 17.1 17.2 17.1 17.2 +.6% 17.4 17.1 16.7 17.0 16.9 17 -. 0 17.1 17.0 17.1 17.0 -.6% uuuuiy , HFET 23.3 23.1 23.2 23.4 23.0 23.2 0 23.5 23.2 23.2 22.7 22.5 22.9 22.0 22.6 22.9 22.7 -.9% from baseline ------- MODEL SM101 "By VALOR the Innovators in Energy Saving Devices " INSTALLATION INSTRUCTIONS Congratulations!
