Our creative team proposed a solution to mechanical problems in all types of internal combustion engines by changing the design of the mechanism of the conversion of linear motion to rotary motion, without any changes to the fuel system of an internal combustion engine, an application for an invention filed in April of last year;
All of these technologies can be applied in the performance of a number of basic conditions
To ensure timely and complete combustion in a short period of time the fuel must meet the following requirements:
1) have good pumpability, to ensure reliable operation of the high pressure fuel pump (at optimum viscosity 2.6 mm2 / s at 20 ° C), good low-temperature properties, the lack of mechanical impurities and water;
2) to provide the desired spray pattern, good mixing and evaporation, this fuel must have an optimal viscosity and specific grain size distribution;
3), the required flammability, easy to carry out a cold start, a smooth increase in pressure and complete smokeless combustion (these properties depend on the chemical composition and fraction of fuel, as well as viscosity, chemical composition of the fuel is estimated cetane number, which characterizes the flammability of the main index of motor fuel properties);
4) did not cause an increased formation of sludge and other deposits on the valves, rings, pistons, coking needle spray (the tendency of fuel to the nagara depends on the chemical and fractional composition, viscosity, solids and water);
5) does not contain corrosive products (corrosive properties of fuel depends on the presence of mineral and organic acids, sulfur compounds, and water);
6) may have a higher heating value;
7) have a high pumpability fuel with minimum leakage through gaps in the plunger pairs with minimum wear of friction pairs.
It used to be that the fuel for high-speed motors must be at 20 ° C, the viscosity of at least 5 mm 2 / s. Studies have shown that the fuel with a viscosity of up to 2 mm 2 / s at 20 SS lubricates fuel injection equipment. Minimum viscosity depends on the injection pressure and other design decisions. With the increase in viscosity of the fuel injection pressure can be increased by 6-10 times.
(The use of technology for integrated activation, in which water is mixed with diesel fuel to form a stable emulsion which is then mixed with vozhdushnymi bubbles, in which the internal pressure in the bubbles is from 10 to 20 bar, can almost halve the required pressure, which reduces the viscosity of fuel mixture in 3 - 5 times in addition admixture 10% water and 8 to 12% of the air in the same proportion reduces the viscosity of the original fuel mixture)
Based on the research and operational tests, the following values of the viscosity of fuel at 20 ° C for high-speed diesel engines: the summer - 3.0-8.0 mm 2 / s in the winter - 2,2-6,0 mm2 / s, for a severe Arctic climate - 1.5-4 mm 2 / s.
Pumpability fuel depends on its low-temperature properties that affect the mobility of the fuel at low temperatures. Low-temperature properties are determined cloud point, the onset of crystallization and solidification.
Cloud point consider the temperature at which the phase homogeneity of the fuel is lost. It begins to thicken due to the release of tiny droplets of water, solid hydrocarbons or microscopic ice crystals.
The temperature at which the first crystals appear visible to the naked eye, is the temperature of crystallization.
Temperature of the complete loss of mobility is called the freezing temperature.
(For the proposed technology mix pour point is lowered proportionally percentage of air and water in the mixture, and, in addition, the high level of turbulence mixture also helps to reduce the pour point)
Mechanical impurities in the fuel standard does not provide for (not allowed). Fuel contaminated non-compliance with rules of transportation, storage and refueling. The most harmful quartzites alumina, because they have high hardness. Precision pair of fuel pumps have clearance 1.5-3.0 mm, so even a small percentage of solids leads to significant abrasion.
(Using the proposed technology abrasives hit the fuel pump is eliminated, thanks to a special system of capillary channels in the device for a complex activation of diesel)
This fuel is more or less constant in the dissolved state water. Its concentration depends on the ambient temperature. The solubility of water in the fuel 10 5 kg / kg. Especially frustrating presence emulsion of water at low temperatures. In this case, the ice crystals clogged cleaning system and disrupted motor. Negative impacts on water fuel system, especially in the high-pressure pump and injectors. It contributes to the appearance of corrosion surfaces precision steam and coking spray nozzles.
(Proposed the formation of ice crystals technology is impossible, and in addition the mixture may have a special section of the heat that eliminates ice crystals, reduces or eliminates corrosion and the formation of coke in the injector nozzles)
Desired spray and mixture formation and evaporation of the fuel become critical in determining the course of the working process as a whole, its effectiveness and efficiency.
Portion of fuel metered high-pressure pump is injected into the combustion chamber in a tight, strongly swirling heated air. At some distance from the nozzle jet nozzles breaks into droplets, forming a flame sprayed fuel. The total number of drops up to several million, and their size varies from 50 to 150 microns. Distribution of the drops in the number and size of very uneven. The quality of fuel atomization is characterized by the number and size of drops, length, width, and angle of the cone spray pattern.
Drop of fuel introduced into the hot air does not ignite instantly. When ignited, the evaporation process is more intense due to the high temperatures in the combustion process. Along with the acceleration of evaporation in this moment there is a slowdown, because there are products of combustion, hampering supply of oxygen to the fuel evaporates. This fact makes it necessary to keep the workflow in a diesel engine with some excess air.
(Proposed technology can provide the required excess air and high uniformity of air distribution in the amount of fuel mixture)
Large heterogeneity fuel mixture in the combustion chamber is responsible for some of the advantages and disadvantages of diesel engines. An important advantage is that the diesel engine can be greatly impoverish the working mixture. This allows you to change the power only through the fuel system. On the other hand, the heterogeneity of the mixture - a significant disadvantage of diesel engines because it is impossible to achieve complete combustion and smokeless.
(Proposed technology provides a highly homogeneous mixture, which can be expressed by the size of air bubbles produced by activating - 20 micrometers)
The process of mixing affects the viscosity of fuel, increase which leads to a deterioration of atomization and evaporation of fuel. At high viscosity large drops increase the length of the torch and hit the wall, which greatly impairs the process of mixing, and at a low viscosity fuel torch is shortened and the combustion chamber is not fully used.
(Proposed technology provides a particle size in 3 - 5 microns, which increases combustion efficiency, reduced viscosity of the mixture in proportion to percentage of impurities and the mixture is formed with an energy advantage effect Bernoulli, which improves the process)
Fractional composition of diesel fuel is estimated final boiling point: the summer - 360 ° C, winter - 340 ° C, the Arctic - 330 ° C.
The complex processes of combustion and mixing fuel engines are fast in a very short period of time, about 10 times faster than gasoline engines, with the same speed.
Combustion rate depends on many factors: pressure and temperature of the compressed air, the concentration of fuel vapor in the air, the chemical composition, the quality of atomization and fuel volatility.
At a delay of subsequent ignition of the fuel combustion process is very intense. She could hear the characteristic knocking engine (similar to the detonation, but the causes are different).
All other things being equal, the reduction in the ignition delay results in a more gradual change in pressure, ie a smooth-running engine. However, the excessive reduction of this period reduces the efficiency of combustion. The process begins as soon as the fuel, much of which is supplied to the combustion products. Fuel droplets are then rapidly evaporate before reaching the zones chamber in which oxygen is not used. The process of mixing is deteriorating, falling output and engine efficiency.
To ensure the normal combustion process should be applied fuel having optimum ignition delay period. Flammability of fuel is estimated cetane number. Numerically, the cetane number of diesel fuel equal percentage (by volume) of cetane in a mixture of alpha-methylnaphthalene, which by the nature of combustion (ignition) is equivalent to the test fuel. Cetane number is determined by three methods: the critical compression, ignition lag and coincidentally outbreaks.
Diesel fuel must have a cetane number in the range of 45-50 in winter and 40-45 in summer. Cetane number is the starting properties of diesel fuels, slightly different on the fractional composition.
When operating the diesel engine is very important to establish the optimum angle of injection of fuel. At a high angle of lead in fuel is not hot air, which increases the ignition delay period and the rigidity of work. Fuel thus can burn up to top dead center, which leads to loss of power, as it creates pressure. With much of the delay of the injection of fuel is burned in the line extension, causing loss of power, incomplete combustion, reduced engine efficiency.
Carbonization in high-speed diesel engines, leading to an overheating engine, coking injector atomization of fuel deterioration. Increased accumulation of carbon promotes incomplete combustion of the fuel, the availability of the fuel complex macromolecular substances and impurities. On the accumulation of tar significantly affect the stability of fuel. Indicators of the quality of diesel fuel, affecting carbon formation and regulated standards, the following: the number of coke, tar, ash, solids and sulfur compounds. Sulfur contained in the fuel, not only affects the weight of the resulting sludge, but also on its properties. Sulphur compounds accumulate in Nagar, increase its density.
Corrosion properties of diesel fuel sulfur content are conditioned, water-soluble acids and bases, as well as water. The presence of sulfur compounds in the fuel test polished plate of electrolytic copper of size 10 × 25 mm. This plate is immersed in a porcelain cup with the fuel, which is placed in an oven at 50 ° C and held there 2-3 hours on a plate appearance of dark brown, gray or black film indicates the presence in the fuel of active sulfur compounds.
Cause corrosion of parts in the main sulfur compounds. Particularly strong liquid corrosion evident in the cold season when starting conditions. Increasing fuel sulfur from 0.2 to 0.5% increases the wear of the cylinder group by 25-30%, to 1% - 2 times. To reduce sulfur corrosion in the fuel additive is added. The most common - zinc naphthenate, which is added to the fuel (0.25-0.30% of the mass of fuel).
(Proposed technology eliminates the presence of sulfur compounds in the mixture, and if necessary can increase the temperature of which is 80 - 85% reduction in corrosion of diesel engine)
The calorific value of diesel fuel is 42,705 kJ / kg.
Aspects of the phenomena of corrosion and corrosion processes in structural elements of diesel engines using the fuel mixture in which diesel fuel is mixed with compressed air
When mixing diesel fuel with compressed air, no water, corrosion processes are excluded in the previous case;
(Proposed technique has two main versions, the first version - intensive mixing diesel fuel with water and then the mixture evenly homogeneous mixing diesel fuel with water with compressed air from mixing with the compressed air in the mixture has a uniform distribution on its volume air bubbles with a diameter of 20 micrometers, with an internal pressure of 20 bar, and each of the bubbles has a shell thickness of 20 micrometers, consisting of emulsion composition which has 92% of diesel fuel and 8% water after injection into the combustion mixture is sprayed onto the particles in the 3 - 5 micrometers, and diesel fuel and oxidant are the environment in which the organic fuel cell is uniformly distributed between the oxidant, helping ignite at lower temperatures and creates an equivalent cetane number 45 - 50;
The second version of the technology is the only mixing diesel fuel with compressed air and, while maintaining the conditions for the first version of the technology, fuel mixture and ignition equivalent cetane number, keep the quality as in the first version;)
