Only in the middle left untouched area. And, okay to put a warning that the pit and could not go, so they put a piece of cardboard on top and poured the sand. In short, nothing was visible. It ended up very sad. I flew into this pit, well, that the machine fell directly on the protection, or do not know what would.

And so, escaped with only splash guards and ripped wing flaps, which until then fasten himself for half an hour. So that the protection of our open spaces is a must. Crankcase protection for our roads – this is essential! To rid yourself of problems, Need to prepare for them beforehand because miser pays twice. Do not rely on the ‘maybe’ Put the crankcase! And here in front of you there is a problem of choice! Now there are many manufacturers who can buy protection crankcase. But how to make the right choice while saving time? There are two types of protective casing – metal and composite. Metal protection crankcase, in turn, are steel, aluminum and stainless steel. Manufacturers of metal protection and there were a great many such protection for a long time, about 10 years ago.

Composite crankcase manufactured in St. Petersburg and the relatively widespread recently. Detailed description of the steel protective casing can be found online at the manufacturers’ websites. The main advantage of steel protection – is the price. At their manufacturing uses ordinary sheet steel, so Steel Protection cheapest. They look like this: aluminum protection are significantly more expensive because the cost of aluminum is higher than that of ordinary steel sheet.

At temperatures greater than 500 and in the presence of high loads, use heat-resistant steel. The physical properties of steel AISI 409 Mark Density (kg/m3) modulus (GPa) Average rate thermal expansion of x (10-6/oC) Thermal conductivity (W / m K) Specific heat 0-100 C (J / kgK) 0-100 C 0-300 C 0-500 C 100 C 500 C 409 7800 200 11.0 11.7 12.4 25.8 27.5 460 steel AISI 409 is a ferromagnetic (magnets). You may want to visit movie star to increase your knowledge. Processing and some technological properties of steel AISI 409 Cutting The most effective way is cutting guillotine or grit using a specially designed besprizhogovyh drives based on SiO2 or Al2O3, as well as oxygen-free nitrogen plasma cutting. Plastic deformation of higher tensile strength of technical means and the higher efforts of deformation in comparison with carbon steels. When bending the steel is important to maintain a minimum internal radius curvature equal to two thicknesses of material.

Subsequent bump in the opposite direction is not recommended – the zone of bending in this case needs to be heated up to 1500 C. Tony Parker takes a slightly different approach. It can avoid the edge crack if bent when cutting metal, cut it with no inner radius, and from the outside. This type of crack may be excluded if podshlifovat outer radius and thus remove the hub stresses. This welding steel welded any fine known methods. Provided that, if taken post-weld dressing operations / cleaning and passivation will not occur in the loss of corrosion properties of the spot welding (including the heat-affected zone). Optimally use arc welding in inert gases subject to a minimum energy deposition in a welded seam. We recommend welding ‘top’ (ie, when the work piece is located below the welding tool).

In as a filler material can be used austenitic wire 309L, Cv-07Kh25N13, Sv-08H25N13BTYU etc. In order to ensure adequate resistance to corrosion and scale necessary to remove the discoloration or etching machined brushed stainless steel and cold propassivirovat 10-20% nitric acid solution. Required subsequent thorough rinsing with cold water and drying. Machining of Reduced strain hardening, compared with the austenitic steel, includes a requirement of using special tools and coolants. Low processing speed, and a small supply of the tool, with enough coolant to prevent any problems when machining steel.

Car Refrigerant

Refilling of car – a process that consists of several stages. To find out the status of car – it is necessary to diagnose. First, visually check the air conditioner and device for mechanical damage, spots, stains, oil, etc. After the specialist auto technical checks of ambient noise and beats when the air conditioner. It then examines the pressure of the refrigerant in the system. For that the ports are connected to fuel hoses, gauge manifold, and in his testimony the expert evaluates the refrigerant pressure on the discharge side and suction.

As a rule, most fault in a car air conditioner is due to refrigerant leakage. In this case, the main task – to detect leaks (using special equipment to detect leaks) and to determine what is cause of its occurrence. The next stage of work – is to eliminate leaks, check for leaks and filling the air conditioner system. Before filling the refrigerant needs to be done vacuuming system to remove air and moisture. Only after this procedure, you can fill the coolant in air conditioning. Filling is performed by measuring the collector or automated filling stations.

Very often problems in air conditioning because of unskilled maintenance, fueling, or repair the air conditioner. If you do not replenish or refill coolant on the contrary, in the near future, this may lead to failure of its compressor. Perform repair or automobile air conditioner service without special equipment is very difficult and it's not enough just to have practical skills. In order to perform maintenance and refueling of air conditioners on high professional level, requires serious theoretical training, understanding the processes occurring in the automotive air conditioning system, a knowledge of contemporary nomenclature of spare parts and the latest technological developments in this area. Thus, it is strongly not advised to refer to unskilled craftsmen, repair and refueling of air conditioners in makeshift conditions.

Batching Zinc

Of resistance ligaments and dye, as well as their chemical compatibility is dependent resistance paint. Paint color is produced by the batching, adding and mixing several dyes. Dyes are mineral or organic. Mineral pigments are divided into two groups: a) natural dyes, such as iron oxide, ocher, etc., and b) synthetic dyes. Some came to us from antiquity.

For example, natural organic colors are: purple – from caterpillars, madder and indigo – from insects or plants. Modern colors mostly of chemical origin. They are produced in the processing of coal, oil, etc., White colors: antimony trioxide, lead oxide, zinc oxide, etc. Due to its high covering capacity and inertness to chemical attack, greater use is titanium dioxide. Black dyes: oxide iron, black mineral (graphite), black carbon, black animal and vegetable dyes.

Yellow dyes: natural and synthetic iron oxide on the basis of cadmium (cadmium sulfide), based on chromium (chromate of lead), based on zinc (zinc chrome-you). Red dyes: natural and synthetic iron oxide, cadmium red-based, orange and red based on molybdenum. Organic dyes: toluidine red. Violet dyes: synthetic iron oxide, organic dyes, indigo family. Blue colors: blue organic indotren, ultramarine blue, phthalocyanine blue organic, blue cyanide. Green dyes: oxide chromium, green, obtained by mixing yellow and blue dyes, pigments, etc. Metal: aluminum powder or glitter, powders, bronze, zinc and Zn-containing, etc. PAINTS feature is that they can be apply not only to painting. For example, zinc oxide is a metal, zinc, dissolved in a bundle in the following proportions: 95% of zinc powder and 5% of the bunch.

No less interesting laboratory studies that determine the change shape and area of the contact patch while moving at different speeds. For resistance to hydroplaning tires greatly affects the residual tread depth. For this reason, self-respecting manufacturers are testing the new tires, so and worn with a 40-60% tread. Maximum mileage or tire wear. Mileage tires, primarily depends on the conditions of the tire: the nature and style of driving, the state of elements of the suspension vehicle (Shock absorbers, bearings, hubs, ball joints), correct wheel alignment (the alignment), road surface and, of course, the tire pressure. The deterioration of any of these parameters drastically reduces the possibility of mileage bus. In terms of tire technology – we're talking about durability and the wear rate of the tread.

This parameter directly determines the number of kilometers of your tires to the maximum wear, all else being equal conditions of the tire. Parameters affecting the bus iznososostoykost outdoor tread, the more open tread, the less rubber in the contact area and, therefore, more specific pressure and speed wear, the rubber in the tread (the presence of special additives), the design of the tire carcass, allowing most effectively stabilize the contact form in motion. Paradoxically, – for passenger cars initial depth of the tread, in the end, does not affect the durability or the maximum mileage tires. The deeper the tread, the greater its amplitude deformations, and thus heat, which ultimately increases rate of tread wear. So do not 'fooled' the tires with deep tread, expecting them to more efficient investment. Such 'technical solution' often guilty little known tire manufacturers from near and far Asia. Rolling resistance. In an era of global environmental crisis and price hike of fuel – all tire manufactures pay more attention to the impact of tires on fuel consumption.

A well-chosen tires can save you up to 5% fuel. Rolling resistance is directly affected by carcass construction, tread rubber composition, which determines its softness, hardness compounds of the tread blocks. This option is most difficult to define 'the eye and touch', not with the objective test results, so the leading tire manufacturers often specify the marking of their tires, tires that data belong to the class 'cost'. The 'E', 'Economy'', Fuel saving … But do not forget that the pressure drop already below the recommended 10-15% negate all possible savings in fuel consumption.

Hot Painting

These resins are used in the automotive industry. Nitrocellulose resins are wastes with incomplete development of the cellulose ester by treatment with nitric acid. Drying resins by by evaporation of the solvent. In pure form, such resins have limiting characteristics. Often, they added plasticizers, depending on the nature and content of which is provided immediately after application shine or paint after polishing.

Nitrocellulose resins are less resistant to weathering and to chemicals than acrylics. They dry quickly and originally used for painting the body vehicles. Epoxy resins are polymers derived from petrochemical by-products. To harden them added catalysts. When air drying epoxy polyamides are formed, with Hot – epoxy phenolics. Poliuretapovye resins are products obtained in petroleum refining and coal. They are the result of chemical interaction of compounds with free hydroxyl izosianatom. Polyurethane paints are one-and two-component.

Paints have exceptional resistance to weathering, hydrocarbon-to-action, etc. They are used in a wide range: from painting cargo tanks truck, etc. before painting and varnishing wood and metal exposed to the harsh climatic conditions. Drying occurs as a result of chemical reaction (polymerization). Polyvinyl materials the addition of anti-corrosive pigments are the basis for the protective paint and soil. Drying paint mononuclear carried out by evaporation of the solvent, and dvuhsostav-GOVERNMENTAL – due to polymerization. Pigments Pigments or dyes – a powder, which gives the paint color. Their main properties and characteristics: opacity, which depends on the refractive index of light, the volume concentration and particle size of the dye; -Coloring ability (organic dyes are more coloring ability than mineral pigments), particle size and distribution, particle shape, (spherical, nodular, lamellar).

The outstanding quality of this system are obvious. Not so much increased the service 'side of the electrode' (in practice it does not burn), and and also the central electrode and the insulator could be made more durable. Not allowed to introduce such a system ignition problems with supply and distribution of electric charge. The next step was improving geometry, lateral and central electrode spark a simple system. If caught in any directory as an example of large companies, then it is possible to find any methods to improve 10-20 spark formation. Form the central electrode and the most radical change example of this model is probably Rapidfire firm Delphi. On the surface of its central rod made of ribs 12 with sharp edges.

On the edges of such a candle descends at least easier than with conventional smooth cylindrical surface of the central electrode. This allows, on the one hand, the lower the threshold of ignition, and on the other – to make it safer and more stable when idling or starting. Vendors Car notice that it is the most dangerous of these regimes in the perception of the likely customers of all cars. Rapidfire Manufacturers estimate that its system compared to the 'factory' spark auto permits by 18% to increase the response reaction accelerator, a 27% stability of idling and a 2% fuel savings, but for what it's anything out there (they) Ford or Chevrolet. No one measured the improvements in the engine car of the average Russian.
