Why HHO ?


 Up until 1982, we had carbureted and fuel injected engines and gasoline was cheap. It was around this time that Electronic Fuel Injection started appearing as factory equipped options available on some cars and trucks. Unlike carbureted engines, Electronic Fuel Injection had to be controlled by a computer. The new technology became very popular, very fast. Electronic Fuel Injection relied on high pressure fuel pumps to provide a finer fuel vapor spray, which increased engine response. Not only was it easier to start a fuel injection engine, it was safer; the possibility of backfires were drastically decreased.

The new injections system let us get more economy out of a gallon of gasoline. The reason, the finer fuel vapor spray.  Well, big oil just could not have that, so in 1987 they had computer controlled sensors forced on us by the EPA. Sensors that kept us from changing our Air to Fuel Ratio.

Gasoline is a hydrocarbon. It needs oxygen in order to burn with a flame. It is the air that provides the oxygen; about 20% by volume.

Poorer air/fuel distribution affects emissions, efficiency, and power, in that order.

 Increased airflow is needed to burn more fuel, which in turn releases more energy and produces more power. The combustion process converts the fuel's chemical energy into heat energy, whether the fuel is supplied by fuel injectors or a carburetor. So anything you do to help your engine breath better will improve fuel efficiency. Use better air filters; such as K&N. Use add on Electric Turbo Fans to force more air into the engine.

An engine's air/fuel ratio must be precisely controlled under all operating conditions to achieve the desired engine performance, emissions, drive-ability, and fuel economy. Modern electronic fuel-injection systems meter fuel very accurately, and use closed loop fuel-injection quantity-control based on a variety of feedback signals from an oxygen sensor, a mass airflow (MAF) or manifold absolute pressure (MAP) sensor, a throttle position (TPS), and at least one sensor on the crankshaft and/or cam   shaft(s) to monitor the engine's rotational position. Fuel injection systems can react rapidly to changing inputs such as sudden throttle movements, and control the amount of fuel injected to match the engine's dynamic needs across a wide range of operating conditions such as engine load, ambient air temperature, engine temperature, fuel octane level, and atmospheric pressure.

So Why HHO

Our air quality is not improving. Oxygen content, in many areas, is not what it used to be. On top of that, computer controlled emissions systems limit the air to fuel mixture in order to maintain a slightly rich mixture instead of slightly lean mixture. This causes excess fuel in the exhaust system. To overcome this, we were forced to use expensive Catalytic converter to burn the excess fuel vapors --- outside of the combustion chambers; Assanine. So why HHO?

Adding pure oxygen to the air being sucked in by the engine increases the oxygen content of that air. Thus, more of the fuel vapor gets burned inside of the engine, where it is supposed to get burned; which means we do not need to buy as much gasoline. Adding oxygen also reduces pollution to the air; less CO2, less Carbon Monoxide, less NoX; no need for a Catalytic converter. The EPA says, "well we can not have that". "Our government would loose to much Tax money". So they make the computers smart enough to keep the air fuel ratio at 14.5 parts air to one part fuel.


 Fuel is saved while the car is coasting because the car's movement is helping to keep the engine rotating, so less fuel is used for this purpose. Control units on modern cars react to this and reduce or stop fuel flow to the engine reducing wear on the brakes
