How does this system work?
The AquaTune system can be retrofitted with nearly any engine. The AquaTune system is comprised of a water reservoir tank that is connected by tubing to the main Processor unit, which is connected to one or more Hydrogen Generator tanks. The processor has 3 inputs: Distilled water, air, and a little electricity. The output of the system is a mixture that is 40% water and 60% hydrogen-oxygen gas.
Internal combustion engines are notoriously inefficient. By mixing hydrogen gas with the intake air, hydrogen's fast flame speed helps to burn the fossil fuel more completely and efficiently, which improves your fuel economy (miles per gallon) and decreases your emissions. Please visit our "How it Works" section for additional details.
Which types and sizes of engine will this work on?
The system will typically work on any gasoline, LPG, NG, or other vapor gas-powered engines including super-charged, turbo and rotary engines. Each fuel type has a slightly varied response, with gas and LPG being closely matched. We provide a huge boost to racing vehicles by allowing the engine to be tuned more aggressively with less detonation and more advanced ignition timing. We just need to know the size of the engine and the number of cylinders. In other words, year, make, model, engine size, fuel type, and turbo or NA.
The Diesel product line operates on the same principles and is made up of a few different models. The HS 415 is for small turbo diesel applications in cars and trucks. The AquaTune HS 320 is for a medium duty trucks. The HS 320 HO (High Output) is our heavy diesel product for semi-tractors or other engines of common size. The AquaTune-D Model is specifically designed for large commercial applications such as stationary rotary equipment. Diesel applications CANNOT use the gasoline unit, however, some high-pressure turbo gas applications like CNG engines might use the applicable diesel unit, depending on the application. You can visit our Gallery to find pictures of engines that are similar to yours.
Is this CARB certified?
No, we have not submitted for CARB certification. If we were to apply, we expect our systems would easily pass the certification requirements. This decision gives us more freedom to continually improve our products to better serve our customers. For corporate accounts considering large orders, we are more than happy to run a cost-benefit analysis of pursuing a CARB certification.
Are there any pumps or electrical circuits that need to be connected?
One of the strong points of this system is that it does not require computer sensor manipulators. On the AquaTune International gas engine units, typically only two wires need to be hooked up. One to positive and one to negative.
How big is this system?
The whole system (gas engines) typically weighs less than 3 pounds and can fit in the palm of your hand, that is, without the water reservoir. You can visit our Gallery to see pictures from over 100 installations.
How often must I add water and do I have to add anything else?
Refilling the water tank is the only maintenance required and the re-fill frequency will vary with your driving. We recommend checking the water tank at every fill-up.
For tank sizes, the average car uses a 2L tank, which lasts approximately 12 to 14 gallons of fuel although this will vary with engine and driving conditions. Larger and smaller tanks are available based on desired range and available space. Semi-tractors driving high mileage typically use 0.75-1.0 gallons of water per hour with tanks that are 10 or 20 gallons in size, although we have installed much larger tanks upon request. 20 gallons of water weighs 167 lbs and is typically not a weight concern. Heavy haul tractors can use 1.0-1.5 gallons of water per hour.
During cold weather, any temperatures below (34 F), it is necessary to add methanol to the water tank (10-50% by volume ). 15% protects down to 23 F and 46% protects down to -40F to act as anti-freeze. The phase change that occurs in turning water to gas lowers the temperature several degrees, so you will need to adjust the mixture to reflect approximately 5F colder ambient air temperature. This is for both gas and diesel models. You now have an engine that is part hydrogen engine, part gasoline engine and part steam engine. This makes for a very healthy, mean and clean hybrid machine! No electrolyte is ever used.
What happens if I run out of water?
If the water runs out there is no harm to the engine. The only thing that happens is that the fuel efficiency, exhaust emissions, and horsepower revert back to what it was before the installation of this system.
Are there any other benefits to using this system?
Other benefits to your engine are that it keeps the engine oil cleaner, for longer because of the lack of carbon deposits. It keeps carbon from building up in the combustion chamber and around the valves, which is especially valuable for high-pressure injection engines. This system also lowers engine oil temperatures by about 25 degrees Fahrenheit; it helps keep the O2 sensor clean; it helps keep the injector stems clean; and it drastically reduces emissions and excessive burning of oil. Fuel efficiency is improved through more complete combustion of injected fuels, which significantly reduces unburned fuel and harmful deposits and therefore extends engine life. In fact, the emissions are reduced to the point that the exhaust smells like the by-product of an ozone machine (We do not recommend a sniff test, there are machines to do that! However, it is generally noticed). Both the EGR valve and the catalytic converter are kept much cleaner. It also extends the life of the spark plugs. It typically stops engine pinging, or pre-detonation, even with lower octane fuels.
How difficult is it to install and how long does it take?
The system is usually quite easy to install and takes approximately 1.5 to 4 hours, depending on the person's expertise and access to the engine. Each processor is pre-set in the factory for the average setting typically used for both water and air injection and is bench-tested to be free of defects. Any adjustments to the system outside of the instructions, including tampering to the unit, will automatically void the Guarantees and Warranties.
The first step for installation is to locate a place for the water tank with a good supporting area away from direct heat sources such as the exhaust manifold. We provide straps to stabilize the water reservoir. Next, mount the processor either vertically or horizontally. Important Note: The processor must be mounted higher than the water tank to prevent water from siphoning into the engine. A bracket is included to assist you in mounting the processor as close to the point of entry as possible: 2 to 8 inches from the point of entry is considered ideal. You will be able to refer to the instructions and emailed photo directions and details specific for your vehicle. Lastly, it's time to start the engine to make any final adjustments per instructions and start getting great fuel mileage and performance.
Will this system void my new car warranty?
No. See U.S. Code - Title 15, Chapter 50, Sec. 2301-2312 of the Magnuson-Moss Warranty Act.
Will putting water into my engine rust the internal parts?
No, engine heat evaporates the water and engines naturally produce "sweat" because a by-product of engine combustion is water. This is the reason you see moisture escaping through the tail-pipe, particularly on cold mornings.
Why haven't I heard of water injection before?
Water injection systems have been around since the 1930s. However, they have come and gone in popularity. The Porsche 911 GT2 RS, Saab 99 Turbo, and Oldsmobile Jetfire were popular before the invention of the intercooler, and we hope the 2019 BMW M4 GTS may be signaling a resurgence of this beneficial technology.
Our system has remained and is considered the best ever made because this is water injection at its highest level. Just as other technologies such as the TV, telephone and the computer have improved and changed over the years, our systems have been continually improved over the past four decades to become the highly refined system that it is today.
Does it make a difference what kind of spark plugs I use?
We have found that the best spark plugs to use are standard or high-performance Iridium or Copper spark plugs. When possible or applicable, you may go to a one-step hotter plug. The platinum in Platinum spark plugs will react with hydrogen and this can cause low-grade pre-detonation. For this reason be certain that whatever spark plug that you decide to use does not include platinum.
Will I need to continue using premium fuel?
No, with this system it's like adding an octane boost and you will typically see the best performance gains by using low to medium octane gasoline. This is possible on most vehicles.
What not to do
In this installation 1) the processor was essentially laid on top of the intake hose instead of being securing mounted, 2) the injection line coming out of the processor has a sharp bend in it and 3) both the injection lines and the water lines were not cut to fit.
Please also note the white coloration of the water feed hose going to the processor is white with calcium build-up. This is generally caused by the use of non-distilled water rather than the recommended distilled water.
In this installation 1) the processor unit was mounted too far away, making the injection line exceed the recommended 8 inch limit 2) the line was not cut to fit 3) the AquaTune provided hose line was not used and 4) the generator were incorrectly mounted near a heat source.
