Starting in 1985, for over 20 years, Magnetizer® was in research and development mode regarding magnetic fluid treatment in general and application-specific system optimization. Through the years, we have defined and refined proper protocols—based on the scientific principles—of how to treat fluids with magnets.

When a properly focused magnetic field is applied to a hydrogen-based fuel, the hydrogen is converted from the para- (less volatile) to a more volatile ortho- state. It potentiates fuel so that the hydrogen attracts and bonds with more oxygen. Getting the oxygen to bond with the hydrogen is necessary for complete combustion. When this happens, we burn more fuel, reducing exhaust emissions and increasing fuel efficiency – better fuel economy and power. More on the theory of its operation you will find here.

We fabricated them in the same process as the heavy-duty truck engines; the Magnetizer® RVEF-D engine fuel saver system for Class-A Diesel motorhomes can save 5-15% diesel fuel. Savings depend on engine age, style of driving, city or highway route, vehicle load, etc. The engine works better, quieter, with more power when needed, and with a prolonged lifetime due to carbon varnish cleanup. In addition, it cleans the combustion chamber and the exhaust pipes and reduces emissions. It becomes a better engine.

The “RVEF-D” system comprises the revolutionary, patented metal Flux Driver Plate® and the latest generation, state-of-the-art, ISO 9001 standard, permanent magnetic ceramic alloys wrapped in proprietary foil material and encapsulated in Commercial Grade-A plastisol. The final product needs no energy to operate or modifications of the air intake, fuel, or coolant lines it is non-invasively attached to. As such, it will not waver any manufacturer’s warranty while bringing a lifetime of benefits.

To properly treat the engine, our exclusive three-component approach creates the most advantageous conditions for efficiency and emissions.

The “RVEF-D” system treats the air, fuel, and coolant utilizing Magnetizer’s highest quality and unique magnetic components. The method includes additional road and truck-proven units to treat transmission coolers and power steering for much better and easier driving.

We mark each component on its shipping box containing plastic ties and a link to installation instructions.

NOTE: Our standard kit contains the air intake energizer system suitable for a line of up to 3 inches outside diameter (OD). If your air intake has an OD of 4 or 6 inches, you need to purchase ($60.00) an additional “TMP-NEG” unit. We sell it separately for your convenience and with minimum effort, included as a related product on the Mundi store.

It takes an hour to two to install the system. It is a DIY kit, but if you feel intimidated, any mechanic will do it according to precise instructions.

Before your installation, you may want to check your emissions, so after the installation, already about 20 miles with the system on, you can measure emissions again. You should see improved engine work, i.e., emissions reduction.

Please keep in mind that for full benefits, you need to have at least 1600 miles driven so that the Magnetizer® will magnetically saturate all metal parts. Our factory has established it over the years as the required Stabilization Period*.

Also, depending on their cleanliness, you will need to change air and oil filters during or after that period to obtain the best results.

*In the engine fuel-air-coolant treatment by Magnetizer® the Stabilization Period is the amount of time it takes to dissolve the carbon/varnish build-up and magnetically saturate all the steel parts between fuel units and the combustion chamber. It is factory-recommended time allowed to soak metal parts magnetically and clean the internal components of carbon varnish, allowing the engine to show more significant than the average amplitude of savings. The economy may initially fluctuate as Magnetizer® gradually eliminates the carbon and varnish during the Stabilization Period. After stabilization, the engine will run smoother and start easier. The Stabilization Period lasts approximately 30 days or 1,600 miles. The economy/performance will increase over that period resulting in higher efficiency. In gasoline engines, the Magnetizer® Engine Energizer Systems provide engines with “HIGH-TEST” performance while using Lower Octane Gas, thereby creating even more significant savings.
