Fuel Preporator® is about diesel engine performance, efficiency and reduced exhaust emissions. Filtration and diesel fuel go hand in hand. In the past, filtration has been at the expense of engine performance. Fuel Preporator recognizes and addresses fuel filtration and delivery needs for the diesel engine.
Here’s What Happens
Sloshing in the fuel tank causes diesel fuel to entrain tiny air bubbles. Also, the fuel transfer pump operating under a vacuum cavitates, producing vapor. Air/vapor from cavitation increases at higher rpms and as the fuel filter gets dirty with use.
The air/vapor, a result of the “vacuum feed” system, is compressible and is carried with the fuel into the fuel injector. The injector plunger now must travel farther to compress the air/vapor and inject the fuel. This delays injection.
Retarded Injection Timing of the engine, which varies with each injection, is the source of rough idling, lost power, increased fuel consumption, increased tail pipe emissions and the reason identical diesel engines do not run the same. All of these are the result of the inadequate “vacuum feed” fuel supply system, the system that is on your engine.
The patented Fuel Preporator® removes air/vapor from the fuel restoring injection timing and performance to factory specs.
Never heard of “entrained air?” These people have:
Caterpillar Special Bulletin 651-1250:
“Normally, #2 Diesel Fuel contains about 10% air in solution, although the air is not visible.”
Cummins Service Topic 5-135:
“The source of the vapor is the fuel itself.”
The Fluid Power Institute at the Milwaukee School of Engineering
confirms that entrained air and vapor is present in all liquids, especially petroleum-based liquids.
