NATURE AND DESCRIPTION OF PROBLEMS AND HANDLING OF SPECIAL DIESEL transport equipment, INCLUDING combat vehicles, such as in a tank;

The key operational and general technical issues and this type of diesel engines should include inability to raise or increase the engine speed due to the fact that it is impossible under current conditions to reduce the time required for mixing diesel fuel with air and this option inhibits the process of increasing the speed of the types of engines and therefore reduces the efficiency of these engines;
Existing design scheme does not allow the use of more efficient versions of fuel blends, which reduces the overall efficiency of diesel engines and complicates their modernization and optimization of the parameters;

With standards and other regulatory and and regulations;

For comparison, the existing technologies mixing fuel-based diesel fuel to the proposed technology, we take the parameters of standards, which are more or less can be improved by using the proposed technology.
These parameters include, - power per unit of volume of the diesel engine (kW/dm3); weight per power ratio (kg / kW);
The basic parameter is: Best brake specific Diesel fuel consumption of Diesel fuel conversion efficiency (g / kW xh);

Description of existing technologies in the production of fuel for diesel engines of all of these types;

Currently, the technology of preparation and supply of fuel into the combustion mixture, which has not changed since the first diesel engines;

With all the modern diesel engine upgrades, basically perfected electronic monitoring and control systems, but does not affect the key elements that could fundamentally change the operating conditions of diesel engines and can significantly increase their efficiency;

The most effective technology of all existing

The main trend in the development of diesel engines and internal combustion engines in general, which can be estimated on the most important criteria - efficiency motor.
Today, the most effective technology allows through improved management systems, fuel processor, selecting the most optimal values of the time intervals for the entire chain of operations from the fuel tank to the exhaust to achieve efficiency values
Reasons of insufficient efficacy in existing technologies:
There is almost complete control over time and the physical parameters of the application process, the injection and combustion of the fuel mixture, under the current system the implementation of these processes is not possible to actively control parameters, physical condition and mixing ratio of fuel mixture itself;
Improving the efficiency of energy is practically limited parameters limiting possibilities fuel mixture;
All known techniques mixing fuel for diesel engines does not change the basic properties and characteristics of the diesel fuel produced on the basis of its fuel mix;
Basically, all the processes of mixing diesel fuel with air are already directly in the combustion chamber when the control process is extremely difficult or even impossible, and from the time of injection of the fuel mixture in the combustion chamber, further events occur without any adjustment, and the result can only be known after completion of the working cycle of the engine;

BASIC PARAMETERS and maybe existing technologies mixing fuel, which offers technology improves;

The time required for mixing diesel fuel with air, using the proposed technology is reduced by at least two times;

The level of dispersion of the fuel spray mixture at its injection into the combustion chamber is increased by at least 50%;

The uniform distribution of air in the volume of diesel fuel after injection increases at least by 2-3 times;

The level of turbulence in the fuel mixture to injection increases at least 5-8 times;

The turbulence level after injection fuel mixture increases by 5-10 times

Temperature of the fuel mixture before the injection is reduced by 7-11 degrees;

Exhaust temperature is reduced by at least 7 - 11 degrees;

The fuel mixture before it is hit by a high pressure pump, there is a compressible gas buffer that compression increases the level of turbulence in the volume of the fuel mixture and, after injection, provides a high level of mixing and separation of doses of fuel dispersed particles;

System vortex mixing diesel and aerodynamic system saturation with the volume of air bubbles, are the equivalent of turbocharging and intercooling, which together allow us to raise the efficiency of the diesel engine and 50%;

The cycle time of mixing diesel fuel with air is reduced by at least 2 - 2.5 times;

When you enter into the flow of diesel fuel compressed air under pressure greater than 10 atmospheres, part of the air dissolved in diesel fuel, which increases the concentration of hydrogen in it, and oxygen, and this contributes to the thermal impact of fuel combustion;

The viscosity of the fuel mixture is reduced at all variants of pre-mixing, both from the air and in more complex scenarios mixing - with the air and the water, the air and water and the additional components of the fuel mixture;

DESCRIPTION present invention, the advantages of offering technology;
Invented a device for dynamic mixing has no moving parts and it should be noted that it applied only effective scheme targeting parts of the device, in which the outer shell is also a three-dimensional gauge that captures and directs all components

Prompted the invention of the subject of which is the effective method of mixing the fuel mixture with a gradual stepwise dynamic impact on the flow of the mixture and the system ukazannnoy effective contact control of all basic parameters of the mixture after completion of the action and before injection into the combustion chamber;

The invention also includes a method and system of fundamental solutions to adjust the process parameters influence on the components of the fuel mixture and the mixture itself, in order to achieve the desired and necessary final parameters and properties of the fuel mixture before it is injected into the combustion chamber;

The proposed device of the invention, the method has three main working section in which consistently diesel fuel in a stream increases the turbulence

The first facing diesel fuel from the tank to the combustion chamber is the hydraulic section, in which the level of turbulence of the flow of diesel fuel increased by almost an order of magnitude, and the stream is converted to the form of a cross section of a circular ring, due to the high viscosity of diesel fuel, the second problem, which standing in front of the hydraulic section, - that of creating a flow of diesel loose structure to what would be introduced at a later stage in this flow of additional fuel components;

The second section is the introduction into the flow of diesel fuel is uniformly distributed in the bulk flow of compressed air, the operation is taking place at the equivalent parameters and properties of the corresponding theorem of Bernoulli;

On the ring boundary between the first and second sections are connected outputs of hydraulic and aerodynamic effects on the operation of diesel fuel, and in this place there are special circumstances in which an intensive mixing of the liquid and gaseous phases of the fuel mixture and, in addition, the conditions created in the ring border area provide additional absorption components of the fuel mixture, for example - the water from the pipes connected to the ring this border zone;

With the passage of the second section of a mixture of fuel components continues to suck the air bubbles, and with a certain degree of saturation of the fuel mixture is formed foam, the state of which can be qualified as a pseudo boiling volume;

The third section accumulates activated fuel mixture and, if necessary, has an additional impact on the mixture, expressed in, or - heat or electromagnetic acceleration of flow of the mixture and applying it to the high-pressure pump;

The benefits of the proposed technology should include several groups of technological and structural factors, each of which in one way or another impact on the efficiency of diesel engines of all types and sizes;

The proposed system provides a homogeneous mixture of fuel components in the correct proportions in a very short time, within 10 milliseconds, with full control over the proportions and other physical parameters of the mixture before it is injected into the combustion chamber, this option solves the underlying problem, such as the duration of the mixing process diesel fuel with air in the correct proportions and concentrations, providing the combustion process and to obtain the necessary level of energy;

The proposed system allows for the same time intervals, not only to mix diesel fuel with air, but also to mix diesel fuel with additional fuel components, including inorganic nature, to provide fuel mixture in the form of a stable emulsion;
