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.

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.
