EcoMax water injection

The topic "Water injection into the engine" for more than a hundred years excites the minds of mankind. It was patented by Mr. N. OTTO, the father of an internal combustion engine, in the 19th century. It began to get real realization only in the last years of our century thanks to the development of microprocessor technology and awareness of the chemical algorithm of the behavior of water in an internal combustion engine.

Any internal combustion engine converts only 25% of thermal energy into work, and accordingly the remaining 75% with a loud noise emits into the atmosphere. Why not offer this part of the heat once more to work on the problem of decomposition of water into chemical radicals for subsequent combustion, without fundamentally modifying the engine? The combustion (oxidation) of hydrogen with oxygen produces water with a large amount of heat released, but to get hydrogen and oxygen from the water for subsequent combustion, you need to spend 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

Water flows from the tank to the pump with the filter, then, under high pressure, to the injection nozzle. The nozzle is mounted on the intake manifold in such a way as to create a finely divided mixture of water and air. The pump and nozzle receive control signals from the control unit, the brain of which is a microcomputer. The microcomputer calculates a portion of water individually for each cycle of the engine. The microcomputer operates with mathematical expressions, which substitute the values ​​obtained from the sensors and the values ​​that were stored in the memory during system setup.

If the device is mounted on an engine with fuel injection, the control unit receives and processes the control signals from the injectors dosing 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 supplied to the pump and nozzle, which is responsible for the water supply. And also, signals are produced that affect the fuel supply, thereby achieving maximum system efficiency.

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

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

Using a microcomputer makes the water injector system easy to operate and configure. Also, the use of microcomputers allows you to accurately calculate and dose 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, seven times the heat capacity of gasoline. It, entering the suction path of the crankcase gases of a carburetor or injector and mixing with air, creates a water-emulsion mixture. The mixture, falling into the collector, cools the air, thereby increasing its density. This leads to an increase in the fill factor of the cylinders and, as a consequence, an increase in power.

The resulting mixture, moving further along the engine path, takes heat three and a half times more actively from the valves, piston surfaces, heads and cylinders, accumulating it in subsequent work. Then, under the influence of high temperature, which in some cases is excessive, water decomposes into free radicals Н-О-Н, participating in the chemical oxidation (combustion) of the fuel, while increasing the completeness of combustion and, again, again leads to an increase in power. A side effect of the abnormal heat capacity of water is the fact that the flame propagation rate, called “detonation”, is controlled by the active selection of energy at the sites of microexplosions. Due to chemical oxidation, not all hydrogen is involved in combustion. Its excess binds to carbon (carbon deposits), cleansing the surface of the cylinder-piston group and oil.

Suppression of the detonation phenomenon allows the use of low-octane gasoline without increasing consumption and power loss in comparison with high-octane gasoline. This is because the difference between the brands of gasoline is 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 fuel combustion, 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 unit in winter (lowers the freezing temperature of water).

On this, the effect of water is far from limited, but it can not be specified, 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 within a few hours by himself using the instructions. It can be used both on cars and on freight and passenger vehicles.


Device description

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

  • An increase of up to 30% in engine torque (especially noticeable in the urban cycle)
  • Fuel savings of 10-35% due to increased torque and vehicle power
  • More efficient engine cooling during hot weather
  • Softness and significant reduction in engine noise, damping of detonation and ignition ignition
  • Increase in vehicle mileage
  • Increased compression and engine life, reduced shock loads in the operation of the crank-piston group
  • Complete disappearance of carbon deposits on pistons, valves, plugs and a three-fold reduction in CO emissions (achieved by optimizing fuel combustion)
  • The possibility of using gasoline with an octane rating lower than that provided by the car manufacturer
  • Ability to ride heavily lean mixtures

Fuel consumption is reduced by increasing engine power, which allows the driver to use higher gears. Ease of operation is carried out due to the complete automation of all processes with a 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 sports.

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

Simple economic calculation

Take for example a car with a volume of 2 liters. The average annual mileage of 30,000 km. Average consumption of 10 l / 100 km. Average savings of 25% (realistically recorded savings amount to 20-35%). We accept the cost of 1 liter of gasoline or diesel for $ 1. And so: 3,000 liters of gas worth $ 3,000 will be spent on 30,000 km. With the installation of the system, costs fall by 25% and amount to $ 2250. And if you consider that you can switch to lower octane gasoline (taking its price for $ 0.9), then the cost per year will be $ 2025. And that savings per year is almost $ 1000.

-And if it's a fleet? --- 20 cars = $ 20,000

- And if the flow rate is not 10l, but 15l? We multiply this figure by K = 1.5 and get $ 30,000

Etc., Arithmetic is simple, everyone can calculate their option for mileage and consumption.

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

Suitable for all types of cars and trucks powered by gasoline, gas and diesel fuel

  • 1. The maximum torque occurs at an air-fuel ratio of 13.2: 1
  • 2. Water Injection - to increase 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 (2 ° - 3 °) in comparison with normal engine operation. In injection engines, the ignition angle is set automatically.
  • 4. Excessive ignition timing will cause a drop in power and overheating.
  • 5. The quality of the atomization of the 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. The cooling of potential hot spots in the combustion chamber eliminates heat ignition, which is the most destructive form of uncontrolled combustion in the combustion chamber.

The effect of detonation on an internal combustion engine

Water injection is a technology that is as old as the car itself. Water injection is able to suppress detonation even when the pressure in the cylinder increases and the octane number of the fuel decreases.

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

The effect 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 approaches the top dead center, the working mixture (gasoline vapors, air and a certain amount of residual combustion products) is compressed. At the right moment, a spark jumps between the electrodes of the candle, and here a primary ignition center with a volume of several cubic millimeters is formed, the energy of which is the sum of the energy of the spark and the energy of the fuel burned 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 metal knock coming from the engine. Sometimes detonation does not give out extraneous sounds, but is manifested in a decrease in engine power.

Some influence on the occurrence of detonation is caused by soot in the combustion chamber

The fact is that deposits on the walls, firstly, worsen heat transfer, and secondly - increase the actual compression ratio. In other words, they create conditions for disrupting the normal combustion process. Moreover, soot can have a known catalytic effect and cause self-ignition of the working mixture. And further. During transient engine operation, carbon deposits sometimes begin to loosen and delaminate; then particles that have lost close contact with the wall easily overheat and can provoke incendiary ignition. It also happens that soot flakes 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 that defy any logic and classification.

Detonation combustion process

Water injection can prevent detonation and works in three directions. First, when water is injected into the intake manifold system to the cylinder cover, small droplets absorb heat from the air. Cooled air has a high density, thereby increasing the amount of oxygen that enters the cylinder. Water has a high heat capacity (it 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 vapor increases the pressure in the cylinder. It acts as an anti-detonant and also cleans the cavities of the combustion chamber from carbon deposits, thus eliminating unwanted “hot spots”.

A bit of history

By and large, any conversation on the topic of innovations for the car can begin with the fact that most of the technologies used today were already known a hundred years ago (this is boost, nitrogen injection, and much more), and eighty percent of the processes occurring 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 water injection 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 had even thought about using this technology to obtain additional power or save fuel - experiments were conducted in order to avoid the phenomenon of detonation (explosion of a fuel-air mixture in a cylinder, instead of progressive combustion). Around the same time, water injection studies were conducted in the United States, the purpose of which was to study the processes occurring in the engine and the use of water injection in aircraft engines.

So the injection of water would have remained forgotten, if not for the plight of the national economy in the postwar years. The system began to be applied again, allowing the use of gasoline with a lower octane rating without sacrificing engine power.

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

Water has a very high heat capacity, which helps to reduce the temperature of the incoming air, and, as we know from the school physics course, less energy is required to compress cooler air. Evaporating in the combustion chamber, the water increases in volume, which means that the pressure inside the cylinder also increases, which means that an increase in power is also observed.

It will be useful to recall that no system can be fully used without an appropriate engine setting - it is either a lean mixture, or an increase in pressure, or earlier ignition. Sharpened Luftwaffe aircraft engines had devices for automatically depleting the mixture during water injection. In our case, the Ecomax microcomputer is automatically configured! , which calculates all the necessary parameters.

And the most “tasty” - a correctly 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 decays, your grandchildren will get the motor.
