EcoMax water injection

The theme "Injection of water into the engine" has been haunting the minds of humanity for over a hundred years. It was patented by Mr. N. OTTO, the father of an internal combustion engine, in the 19th century. It began to receive real implementation only in the last years of our century thanks to the development of microprocessor technology and the realization of the chemical algorithm for the behavior of water in an internal combustion engine.

Any internal combustion engine converts only 25% of the thermal energy into operation, and, accordingly, the remaining 75% with a loud noise emits into the atmosphere. Why is it that this part of the heat cannot be offered to work once again on the problem of the decomposition of water into chemical radicals for subsequent combustion, without fundamentally altering the engine? During the combustion (oxidation) of hydrogen with oxygen, water is obtained with a large amount of heat released, but in order to obtain hydrogen and oxygen from water for subsequent combustion, it is necessary to expend as much heat. This explains the unshakable law of conservation of energy. So the actions are zero !!!

The principle of operation of the Ecomax system

From the tank, water enters the pump with a filter, then, under high pressure, to the injection nozzle. The nozzle is installed on the intake manifold so as to create a fine mixture of water and air. The pump and injector receive control signals from the control unit, the brain of which is a micro computer. Microcomputer calculates the portion of water individually for each engine cycle. The microcomputer operates with mathematical expressions into which the values ​​obtained from the sensors and the values ​​that were stored in the memory during system setup are substituted.

If the device is installed on an engine with fuel injection, the control unit receives and processes the control signals from the injectors that meter the fuel supply. The control unit also receives and processes signals from the engine temperature sensors and the presence of water in the tank. The control signals generated by the control unit are fed to the pump and the nozzle, which is responsible for the water supply. And also, signals are generated that affect the fuel supply, and this achieves maximum system efficiency.

If the device is installed on a carburetor engine, the control unit processes the signals from the ignition coil, temperature sensor, throttle position sensor, and water sensor. For the most effective operation of the device together with the carburetor, it is necessary to adjust the carburetor (it is necessary to reduce the fuel supply). The control signals generated by the control unit are fed to the pump and the nozzle, which is responsible for the water supply.

The proposed water injector system is built on the basis of modern technologies using a micro computer and is a complete device that is installed under the hood of a car.

The use of a micro computer makes the water injector system easy to operate and set up. Also, the use of a micro computer allows you to accurately calculate and dispense the required amount of water, which depends on the engine operating conditions, its temperature, crankshaft speed, throttle position, etc.

Water has an abnormally high specific heat capacity, seven times the heat capacity of gasoline. It, entering the suction path of the crankcase gases of the carburetor or injector and mixing with air, creates a water-emulsion mixture. The mixture, entering the collector, cools the air, thereby increasing its density. This leads to an increase in the filling ratio of the cylinders and, as a consequence, an increase in power.

The resulting mixture, moving further along the path of the engine, three and a half times more actively removes heat from the valves, surfaces of pistons, heads and cylinders, accumulating it in subsequent work. Then, under the influence of high temperature, which in some cases is excessive, water disintegrates into free radicals H-O-H involved in chemical oxidation (combustion) of fuel, thus increasing the completeness of combustion and again, leads to an increase in power. A side effect of the anomalous heat capacity of water is the fact of suppressing the speed of flame propagation, called "detonation" due to the active energy extraction at the sites of microexplosions. Due to chemical oxidation, not all hydrogen is involved in combustion. Its excess binds to carbon (carbon), cleaning the surface of the cylinder-piston group and oil.

Suppressing the detonation phenomenon allows the use of low-octane gasoline without increasing consumption and power loss in comparison with high-octane gasoline. This is explained by the fact that the difference between gasoline brands lies only in the presence of impurities that increase its detonation resistance.

It should be recalled that the principle of burning gasoline in cylinders is expressed by a simple school formula:

It follows that the presence of water in the engine, which occurs as a result of burning fuel, does not cause corrosion. The use of alcohol mixtures does not improve the dynamics of the engine, but only contributes to the operation of the installation in winter (lowers the freezing point of water).

The effect of water is far from being limited to this, but this cannot be stipulated, since it is the property of the manufacturer achieved by many years of testing.

To install the system on a car, no specialized auto repair shops are required, with basic technical knowledge of the car’s design, any driver can install it on his own within a few hours using the instructions. It can be used both on cars and on cargo and passenger transport.


Device description

This device is an automated water supply system, that is, a water injection system with thermal control and selection of the optimal water flow depending on the engine speed. Using the Ecomax system in your car you acquire the following:

  • Up to 30% increase in engine torque (especially noticeable in the urban cycle)
  • Fuel savings of 10-35% due to the increase in torque and vehicle power
  • More efficient cooling of the engine during the hot period.
  • The softness and a significant reduction in the noise of the engine, detonation suppression and glow ignition
  • Increased car service interval
  • Increased compression and engine life, reduction of shock loads in the work of the crank-piston group
  • Complete disappearance of carbon on pistons, valves, candles and reduction of CO emission by three times (achieved by optimizing the combustion of fuel)
  • The possibility of using gasoline with an octane number lower than that provided by the car manufacturer
  • Ability to drive on very lean mixtures

Reducing fuel consumption is accomplished by increasing engine power, which allows the driver to use higher gears. Ease of operation is carried out due to the full automation of all processes by the microcontroller system. Similar systems of this kind have been used in piston engines in aviation for about 70 years, which proves their relevance and reliability. And also in the sport.

An example is the well-known AN-2 “Kukuruznik” aircraft, which, thanks to the use of a water injection system in the engine during take-off mode, increases power from 900hp. up to 1125l.s (manual for the engine ASH-62).

Simple economic calculation

Take for example a / m volume of 2n. The average annual mileage of 30,000 km. The average consumption of 10 l / 100 km. The average saving is 25% (actually recorded saving is 20-35%). We take the cost of 1 liter of gasoline or diesel for $ 1. And so: for 30,000 km will be spent 3,000 liters of gasoline worth $ 3000. With the installation of the system costs fall by 25% and amount to $ 2,250. And if we consider that it is possible to switch to lower-octane gasoline (having accepted its cost for $ 0.9), then the costs per year will amount to $ 2025. And that savings in the year nearly $ 1000.

-And if it is a car park? --- 20 cars = $ 20,000

- And if the consumption is not 10 liters, but 15 liters? Multiply this figure by K = 1.5 and get $ 30,000

Etc., Arithmetic is simple, everyone can calculate their version by mileage and consumption.

Suitable for all types of cars and trucks on gasoline, gas and diesel fuel.

Suitable for all types of cars and trucks on gasoline, diesel and gas.

  • 1. Maximum Torque occurs when the air / fuel ratio is 13.2: 1
  • 2. Water Injection - for increasing power the most effective in the ratio of 50/50 alcohols (or methanol) and water.
  • 3. Water Injection requires the installation of an earlier ignition angle (2o-3o) in comparison with the normal operation of the engine. In injection engines, the ignition angle is set automatically.
  • 4. Excessive ignition timing will cause power loss and overheating.
  • 5. The quality of spraying water mixture - is directly related to the effectiveness of the system. Smaller droplets cool the combustion chamber better and more evenly.
  • 6. The introduction of water allows you to work at higher pressures without detonation. Higher pressure will increase torque.
  • 7. Cooling potential hot spots in the combustion chamber eliminates glow ignition, which is the most destructive form of uncontrolled combustion in the combustion chamber.

Impact of knock on an internal combustion engine

Water injection is a technology that is as old as the car itself. Water injection can suppress detonation even with an increase in pressure in the cylinder and a decrease in the octane number of the fuel.

This method has another advantage - the availability and low cost of water virtually anywhere!

Influence of detonation on engine operation and its elimination

The normal process of combustion of the fuel charge in the cylinder is as follows. The piston is approaching top dead center, the working mixture (gasoline vapors, air and some amount of residual products of combustion) is compressed. At the right moment, a spark jumps between the electrodes of the candle, and here a primary center of ignition of several cubic millimeters is formed, the energy of which consists of the energy of the spark and the energy of the fuel burnt in this zone.

Detonation occurs when the fuel-air mixture in the cylinder instead of progressive controlled combustion spontaneously explodes. This causes a sharp increase in pressure and temperature in the cylinder, which can damage pistons, rings and even the head. Detonation can sometimes be heard as an extraneous metallic knock coming from the engine. Sometimes detonation does not give out extraneous sounds, but manifests itself in a decrease in engine power.

Some influence on the occurrence of detonation has a deposit in the combustion chamber

The fact is that deposits on the walls, firstly, impair heat transfer, and secondly, they increase the actual compression ratio. In other words, they create conditions for disrupting the normal combustion process. Moreover, the soot can have a known catalytic effect and cause self-ignition of the working mixture. And further. In transient modes of engine operation, the carbon sometimes starts to loosen and stratify; then the particles that have lost intimate contact with the wall easily overheat and can provoke a glow ignition. It also happens that the scales of soot come off, but for some time they are not removed from the combustion chamber, but remain in it. They easily heat up and set fire to the working mixture at the most indefinite moment even at the inlet. So are generated; "wild" knocks, not amenable to any logic and classification.

Water injection can prevent detonation and works in three directions. First, when water is injected into the intake manifold system to the cylinder head, small droplets absorb heat from the air. The cooled air has a high density, thereby increasing the amount of oxygen that enters the cylinder. Water has a high heat capacity (can absorb a lot of energy with a slight increase in temperature). Then, small droplets evaporate in the cylinder and cool it, while the resulting steam increases the pressure in the cylinder. It acts as an anti-detonant and also cleans the cavities of the combustion chamber from soot, thus eliminating unwanted hot spots.

A bit of history

By and large, any conversation on the subject of innovations for a car can begin with the fact that most of the technologies used today were already known a hundred years ago (this is pressurization, nitrogen injection and much more), and eighty percent of the processes taking place in the cylinder , not studied to the end to this day.

As already noted, most of the technologies are far from new, and the first experiments with the injection of water into the engine began in the 1930s (the first patent for such a system was issued in the USSR in 1934!). In those days, no one even thought about using this technology to obtain additional power or fuel economy — experiments were aimed at avoiding the phenomenon of detonation (explosion of a fuel-air mixture in a cylinder, instead of progressive combustion). At about the same time, water injection studies are being conducted in the United States, the purpose of which is to study the processes occurring in the engine and the use of water injection in aircraft engines.

It would have remained forgotten water injection, if not for the plight of the national economy in the post-war years. The system began to be applied again, allowing the use of lower octane gasoline without sacrificing engine power.

Although we say "water injection", in fact, pure old kind H2O allows, to a greater extent, to reduce detonation (plus, acting as an antioxidant, prevents the deposition of carbon compounds). And now we will explain why.

Water has a very high heat capacity, which contributes to lowering the temperature of the incoming air, and, as we know from a school physics course, less energy is needed to compress cooler air. Vaporizing in the combustion chamber, the water increases in volume, and hence, the pressure inside the cylinder increases, and therefore, there is an increase in power.

It will be useful to remind you that no system can be fully used without proper engine tuning - this is either a lean mixture, or an increase in pressure, or an earlier ignition. The “ground” aircraft engines of the times of the Luftwaffe had devices for automatically depleting the mixture during water injection. In our case, the Ecomax micro device computer is auto tuning! which calculates all the necessary parameters.

And the most "tasty" - properly installed and configured system is absolutely safe for the engine! Even more - as already mentioned, water prevents the deposition of carbon compounds! In a word, when all the iron is rotten, the engine will still get to your grandchildren.
