As with all revolutionary ideas, EngineMaxx is very, very simple.

A basic truth of the diesel engine stands behind EngineMaxx: diesel fuel burns best when it’s dense. The denser the fuel, the more efficient the combustion. Fuel density in the Common Rail Fuel System depends on an idealized mass flow rate, a rate that varies by engine type. Using a patented process, EngineMaxx tweaks each engine to ideal pressure, to the best possible rate of fuel flow.

And two big advantages happen:

1. A higher rate of flow for fuel reduces heat absorption from the engine, thereby boosting fuel density -with all the benefits of higher horsepower, increased mileage, and reduced emissions that follow;
2. Higher flow rates flush cavitation (air bubbles created by fuel being sprayed under pressure into the engine’s cylinders) past the injector sites and, once more, the fuel is made more dense.

Dense fuel in the rail tells your engine’s computer that individual cylinders somehow require less fuel to perform identical work. Consequently, the computer reduces the millisecond of interval for the opening and closing of the injector at each cylinder. The result: less fuel actually used to deliver even more horsepower.

Here’s why.
The factory-design of engines makes the variable efficiency of combustion at individual cylinders almost inevitable. Necessarily, combustion efficiency at Cylinder #1 is much higher than at Cylinder #6. The villain here is aeration.

As aeration carried through the rail increases cylinder to cylinder . . . more at #3 than at #2, still more at #4 than at #3 . . . the computer “stair-steps” the fuel injected into sequential cylinders, calling for more and more fuel to be injected down the rail. By flushing aeration past the injector site, EngineMaxx allows a more complete burn of both fuel and NOx.

And suddenly.
Cylinder #6 is using essentially no more fuel than Cylinder #1. More power. More efficiency. Much less noxious engine emission.
