How H2-O2 Accelerant Gas Systems Work
By Andrew Evans
How is it possible for an H2/O2 accelerant gas system to improve fuel efficiency by 10% – 20%, increase horsepower by ½ gear, reduce diesel particulates by 67% and smog causing NOx by 48%? It all comes down to the unburned fuel that exhausts from every diesel truck.
The problem is that diesel fuel does not burn uniformly across the cylinder combustion chamber. Diesel in hot spots near the centre of the cylinder burns well. But fuel around the cooler cylinder walls does not ignite at all or does not burn completely during the brief ignition cycle. This unburned fuel leaves the truck in three ways:
1. Carbon Monoxide (CO) where the oxidation process does not occur completely;
2. Hydrocarbons (HC) which is simply raw diesel, unburned because the air-fuel mixture does not achieve the necessary temperature for combustion;
3. Diesel Particulate Matter (PM) which is the agglomeration of very small particles of partly burned fuel, partly burned lube oil, ash content of fuel oil, and cylinder lube oil or sulfates and water.
These emission problems are greatest during idling, light loads, or periods of irregular operating conditions where rapid change in engine speed contribute to unburned fuel.
An H2-O2 accelerant gas system injects a very small amount (200 ppm) of hydrogen and oxygen gases into the air intake of the diesel engine. Hydrogen has a flame speed of nearly 300 centimeters per second, or ten times faster than the diesel flame speed of 30 cm/s. Thus with even a very small amount of hydrogen gas, the flame front expands across the entire cylinder volume in a tenth of the time. The result of this dramatically expanded flame front is that virtually all of the diesel fuel is ignited and burned, including the fuel in the centre and around the cylinder walls.
A further problem with diesel engines is the exhaust of Nitric Oxide (NOx), one of the major smog causing chemicals. NOx arises when normal nitrogen and oxygen from the air chemically combine at high diesel engine temperatures. A properly designed H2O2 system also allows a controlled amount of moisture to travel into the air intake along with the accelerant gases. This is much less moisture than would be experienced on a normal foggy day. During evaporation, this moisture acts as a heat sink, reducing temperature spikes and cutting NOx production by half.
Thus the fuel efficiency and emission reductions benefits of an H2-O2 accelerant gas system are obtained simply because all of the formerly unburned diesel fuel and the various by-products are burned. A driver can ease off the throttle and still reach the normal operating speed and power.
Of course another benefit of improved diesel combustion is greater horsepower. No longer is unburned fuel being sent out the exhaust. All of the energy from the fuel is transferred to the drive train, giving the power needed to climb over the longest hills. Truckers tell us that the increase in power is about ½ a gear.
The Empire Hydrogen Fuel Enhancement System splits distilled water into H2-O2 accelerant gases through electrolysis. A strong electric current is passed through an electrolytic solution between a series of stainless steel plates. Water (H2O) is split into separate H2-O2 gas molecules that are injected directly into the truck’s air intake just in front of the turbocharger, giving all of the fuel efficiency, horsepower and emissions benefits described in this article.
