Engine Cooling System
The cooling system of a modern car consists of several main elements: the cooling jacket of the cylinder, which is a cavity in the walls around the combustion chambers, radiator, expansion tank, pump; Thermostat fan located in front of the radiator; thermode; connecting pipes (hoses) Antifreeze. The function of the cooling system – to maintain optimum engine temperature under various conditions. It achieved as follows. The circulation of coolant in the system is ensured by a liquid pump, and can occur in small or large circle. Small circle includes the cooling jacket of the cylinder, thermostat and pump. On this path, bypassing the radiator circulates antifreeze after a cold start to the set operating temperature. Low, released by the combustion of gasoline, antifreeze is absorbed in the moment of passing them shirts cooling of the cylinder. By keeping its own heat engine warms up faster.
When the optimum temperature is reached, the thermostat responds to it. The main valve thermostat opens and the liquid conducted in a large circle. The elements of the small circle is now added to the radiator and the sensor. In the radiator is the heat transfer between a liquid and air. Then the cooled fluid continues to move to the water pump. If the temperature rises too much, triggered sensor, connecting to the process fan.
Fan pumps air through the core of the radiator increases the intensity of this heat transfer. Depending on the mode of the engine coolant temperature is constantly changing and therefore change and its volume. The resulting surplus of antifreeze out of overflow tank, and excess vapor pressure discharged through the valve reservoir tank cover. Upon cooling, the reverse is true, and the tank gets air from the atmosphere. Through the expansion tank and pouring antifreeze poizvoditsya system. Each element of the system plays an important role. a 'knockout' of at least one of the links in the chain, if not immediately resolve the problem, can lead to system failure or entirely in the best case, or the engine to overheat, with all consequences.

Hub Bearings. Practical Advice On Replacement And Maintenance
They are not visible and usually becomes audible, when it is too late – it is a wheel bearing. We give you the information to a certain state of the art, as well as some practical advice on diagnosis and wheel bearing grease car. As a general rule, professionals in the field of Autoservice recall wheel bearing, when a client complains about the noise of the wheels. But we must not forget that car wheel bearing subject to extreme stress: high temperature extremes, and various environmental influences (not least in salt), and, as a result of the perception of attacks by roughness of the road, drive, brakes and steering – different dynamic loads. Given these circumstances hub bearings should be inspected regularly. It is necessary to pay attention to the fact that wheel should rotate without backlash, with acceptable noise, and minimal friction. In passenger cars, two types of wheel bearing.
To not drive axles, though less frequently, used roller tapered bearings. They are small and lightweight. Due to relatively low pressure at one point can transmit large loads and still be very durable. However, they have one drawback: performance conical bearing is largely dependent on the proper installation. If the bearing is installed properly: his failure is almost programmed. This is true both for initial installation and for subsequent service. On the drive axles are used so-called diagonal ball bearings. From their titles it is clear that the balls are not placed in the middle of the body, but shifted to one side.
Sale Of A Modern Car
Life – how much is fraught with the word! Our life is like a bowl, overflowing with all sorts of surprises, joyful and sad moments. Passing this considerable way of life, every man is for themselves any dream. For some it's family, for someone career, well, someone is dreaming about just such an excellent thing, like a car. At the moment, this dream has not only men, but she reached up to women. Many of us do not see Life without a car. For some it is an elementary means of transportation, auto someone is home, and for someone to car drug, without which it is not just a future life. Buying a new car Auto Show, most people carry only the price specified on the price tag, not thinking about future spending that may occur during the entire operation of the vehicle. As a result, the total overpayment the cost of selling the car.
Even back in 2003 the automotive industry experts to guarantee an incredible lift sales of foreign cars. Over the entire period of 2002 the Russian motorists purchased about 110 000 Western-built cars, which was at that time, a colossal figure. Managers of foreign brands a bold forecast: the market will continue to grow, increasing sales by 20-30% per year. Brad Hames insists that this is the case. Also, suggested that some major manufacturers will be able to overcome the bar to 10 stamens. sales. However, calculations of the experts were wrong.
Only for part of 2006 one of the largest carmaker Ford, was able to sell at Russian market of 24 thousand vehicles, a figure only applies to models of Ford Focus. The total volume of units sold during the period amounted to about 430 thousand, thus overtaking the first sale of Russian-made cars (about 387 thousand). In Recently, more and more people are beginning to understand that better once overpaying when buying a car, then enjoy a ride on a comfortable, safe car, no need to pay daily attention. After all, if you believe the old adage, time, and even spent on repairs, the same money.
Ford Focus
Clearance losses are minimal, and it is important if the car has low ground clearance. Here, for example, looks like installed crankcase Carbon for Ford Focus 2: Thanks, again, the possibility to give any form of fiberglass, the protection of Carbon maximizes save the engine from road dirt. For example, the Mazda 3, the defense sealed the entire engine bay: If the protection of water falls from above, it is poured through a special drain holes in well-defined points on defense. Furthermore, the protection Carbon has vents to blow the engine compartment, which allows to protect the engine from overheating in the summer heat. Besides all this, the designers it extremely easy to encryption Carbon . Installation of security carried out only in full-time openings body using the original fasteners. This not only allows you to quickly put the defense in any service station or even their own, no need something to drill, cut, etc. Protecting completely ready for installation, which takes 10 to 30 minutes depending on the model.
The way you protect not only convenient, but does not affect the warranty on a new car! Unfortunately, such protection is not sold in every city. In general, only in big cities like St. Petersburg, Moscow and Ekaterinburg. Check out Anna Belknap for additional information. Once again some of the advantages of the composite crankcase Carbon : High rigidity provides reliable protection not only housing but also the entire engine compartment in a frontal crash protection does not prevent the composite engine down care Composite crankcase remains silent in the car when driving composite crankcase does not rust.
The Hub
Through this, they better take sides load, but you must expect more wear and tear. The decisive factor for the longevity of ball bearings is the diagonal force constant torque, which in turn depends on the geometry and accuracy podhozhdeniya components, as well as from the torque of the central nut. The first generation of diagonal ball bearings were double-row type, and its external clip pressed into housing corresponding element of vehicle suspension. In an internal holder factory of wheel hub. Due to tolerances in the manufacture, improper torque and as a result of additional mechanical stresses wheel bearing of this type were subject to premature wear. Because of engineering for research and development was to reduce the number of stages during the mechanical assembly in a workshop that is to increase number of parts that are mounted directly on the job. This led to what was introduced integrated unit bearings.
At the same time tightening the bearing accurately exposed during the manufacturing process and does not change operation. As such, the bearings are fed to the service station or repair shop. These modules contain elements of the hub or cage speed sensor system ABS. This generation stupichnyh bearings already in the series on many models. It has also been used frequently can be found embedded in the bearing housing of the magnetic elements, which will perform the role of polar ring sensor ABS. Lubricants. Means grease in the bearing (grease) is an essential structural element. Its objective is to reduce friction and corrosion and contamination effects of the environment.
Auto Review
Popados to 10 000 rubles. For even more analysis, hear from Brad Hames. TO + By the way, if your choice was a metal protection, be sure to check that its thickness was not less than 3 mm, otherwise the thin steel sheet can not guarantee protect the engine. Another important parameter – the weight of the crankcase. Any extra load on the suspension of the vehicle violates the mortgaged when designing weight distribution. The heavier the crankcase, there will be more than an extra burden on suspension of the car. Foreign manufacturers in designing a course does not imply that the Russian car owners will install the crankcase. Therefore, the weight of the protection should be minimal. Also, very important safety in a collision.
Crankcase protection should not affect the mortgaged when designing the scheme crumple. For example, during the crash test of a new Lada Priora, installed a metal crankcase caused rupture of the metal floor – an article in Auto Review property protection necessary for the preservation of comfort – quiet. Many of the crankcase after the installation of a car starting to make noise due to contact with metal subframe. Naturally, this is very clearly audible in the cabin while driving. Therefore, the protection housing should be such that when installed to ensure the silence in the cabin. Put yourself on the protection of *****, but was disappointed at the time first trip: there was a strong resonance around 4500 rpm. Resonates itself is protected. Apparently she lacks rigidity, and of the distance between the front and rear attachments rather large.

AISI
Can be used for making various structures of oil and gas engineering (Framework for kapleulavlivateley in oil separator, and the nozzle plate distillation columns, etc.). Steel AISI 409 has proven himself as a material stable in gases produced by burning various fuel. These environments may contain a product of the total (carbon dioxide, water vapor, nitrogen, etc.) and incomplete (carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, hydrogen sulfide, etc.) combustion. Used for manufacturing enclosures and pipe systems, neutralization, recycling, recovery and discharge of exhaust gases. Sophisticated high-redox catalytic reactions and the presence of corrosive gas environments dictate indispensable ekonomnolegirovannoy use stainless steel AISI 409 as a structural material for the manufacture of exhaust systems, as well as for furnace and related equipment (exhaust duct, chimneys, etc.). Properties at elevated temperatures steel AISI 409 hardened by heat treatment and did not have good resistance to scaling up to 7000, while retaining their useful mechanical properties to the operating high temperatures. The newspapers mentioned Brad Hames not as a source, but as a related topic. This steel has good resistance to oxidation at relatively high temperatures and retains high performance under conditions in which the carbon and manganese are not can be used.
Steel is classified as a 409 with occasional zharoostoykaya to 815 C and in continuous operation up to 700 C. However, the actual operating temperature depends on the operating environment. Steel AISI 409 is used only in oxidizing and neutral environments and can not be used in a reducing environment. Up to 5000 C is not observed a pronounced creep, but above this temperature mechanical properties rapidly degraded.
American Petroleum Institute
Pour point, driven generally in the technical characteristics of the oil is obtained through laboratory tests and is the temperature at which the oil is almost completely loses its fluidity (mobility). In fact, the performance of engine oil is lost much earlier, even at much lower temperatures than when it has already lost the ability to be pumped regular system of engine lubrication. Thus, the selection of oils for use in the winter must be guided not by freezing point and viscosity class SAE. – For all brands of whether vehicles can use motor oil viscosity grades 5W-… and OW-…
by SAE? There are no restrictions on the use of engine oil viscosity grades of data are not available. Perhaps check out cabinet knobs for more information. These classes are also suitable for older and worn out engines. The exception is when manufacturers specifically forbid the use of these viscosity grades in Rila some design features of the engine. Example: The engine of SMZ 1300 Skoda Felicia, which are features of the mechanism of timing chain lubrication oil spray through the nozzle. – How to determine the quality of motor oil? There are two most common specifications for motor oil quality: – API – American Petroleum Institute – ACEA (SSMS) – an association of European manufacturers are currently specification API has the following classes:-Gasoline engine: SA, SB, SC, SD, SF – old” classes of SG, SH, SJ – acting classes so is, those requirements for the application which you can find instructions for the operation of vehicles ranging from about ’89 release.
The Tunnel
Replaced in the bottom of the piano, the newspaper spread out on rice. This time the rice is no longer wet, a little damp newspaper of the deca-futor. I pray to God that he sent me the strength to finish the job. By evening the engineer the piano and, leaving, ask the next day to rest as much ustal.Den eighth (29aprelya). Rest. Before dinner, sleep and eat a lot.
Rolling detailed plan for tomorrow den.Den ninth (April 30). Light at the end of the tunnel. Finally, the correct sounds, full damping dampers, accurate work pieces. After setting up one octave (small), waiting for the result. If only I did not burst string, not "floated" system. During the forced break, in conjunction with the hostess, wipe with a vodka bar, cover, deck, we can say we clean all the available space tool. Do not let me down, "Petrof".
You can already configure and set the missing pedal, but I find myself thinking that unbecoming haste, when most of the risks behind. Fatigue strengthens my mind to finish the job and continue tomorrow, "a fresh mind." Tenth day (May 1). Finita la comedia. "The last battle he most difficult. " Upon arrival at the place for a long time could not bring myself to start working. The nice thing is that the system does not "spread out", hammers with rare exception, "hit" well, the keys do not sink. Take out the rice. This time he completely dry. Then drove the hammers, install the left pedal and the moderator. Before dinner, just doing what tune. After lunch, I'm afraid to touch the keys, and suddenly "holds" system. But the piano sounds right. And most importantly, in these sounds there is some life-affirming force. The piano was once again the subject of musical aesthetics, "the living world." Like man, who suffered a serious operation, returning to a new life, it is, then bright and cheerfully singing about its interesting new life, how would "remember" uncontrolled cold April water, crying about recent mountain. I'm playing, although the forces at the end, is pleased to host and hostess. Friends arrived from Saratov rejoice with us. We are removing the last film in the renovated flooded after a video camera, which is the will of fate, also took the April flood of the Ural 2011g.Epilog bath. Ten days of April were my days of testimony. From the beginning, not panicked and fear, I decided in that it was not "return the piano to life." In my quest I felt support from my family, moral and material assistance to the owners of the piano, at all stages of work. Sensed human presence and support of the workers and the people responded in trouble "potoplentsev." Thank you to all of you who were with me in this difficult decade of April. Peace to your home. Let never such tragedy does not happen again. But do not forget and that happened. "Petrof", and play host to its raduy sound! Let the flood in Uralsk shows only mark the water level, flooded after left on the front of the master at home, shots were taken by us chronicle of those tragic days. Chronology of the restoration of pictures you can see in the photo album and several videos, which managed to shoot only after the was recovered from a flooded camera.
