Modern Motor Oils

On the one hand, each owner of the vehicle is aware of mandatory timely procedures for the replacement of motor oil. However, on the other hand, not all understand the importance of proper selection of oil in accordance with Engine type, seasonal and operational conditions. But a variety of options in connection with different characteristics, viscosity and density, as well as the presence of additives, modifiers and additives, allows for selection of oils most accurately. The importance of correct choice is that the bug can cause substantial damage to the engine. For more information see John Brown. Due to improper or insufficient lubrication components and assemblies will be hard to wear that may even lead to jamming the motor. Fairly common misleading arguments is the reluctance of modern high-quality motor oil in vehicles older generations. Is justified that the car was designed and produced, when synthetic oil was not yet.

However, the use of modern Motor oils with similar characteristics will provide "the heart of the car" more protection due to modern additives that can generally extend its life and increase the reliability indices. What is with regards to the parameters that should be selected motor oil, then in the first place will be indicators viscosity. That's viscosity determines the properties of the oil to remain fluid and lubricating all sliding surfaces, and does not solidify even at extreme temperature loads. After all, it should be noted that the temperature range engine is quite wide. When engine temperature equal to the environment, and in winter it can be -40 C, performance at 90 C on the dashboard report only the coolant temperature. While the motor oil can work in the engine, where the temperature dostigaet150-160 C. Temperature Motor oils will depend on the mode of operation of the engine, but rather on the number of turns at high torque, which can be sufficiently high during sudden overtaking, driving up the hill and with the load. An important characteristic of motor oil is its ability to uniform lubrication mechanisms in different temperature ranges, which is achieved by the addition of various modifiers to ensure stable operation. Also additives used in modern Motor oils may form the protective tungsten or molybdenum film on the surface of metal parts. It is therefore timely replacement and proper selection of engine oil will not only ensure the stable operation and motor protection, but also can increase the capacity and lifetime of the units of the automobile.

Chinese Buses

Since 2006, Chinese production of buses is in stable condition, and even shows a tendency of growth. Over the past few years the market bus production in China began to develop and expand. For Russia, China – One of the most attractive partners in the supply of buses. Russia fleet of buses for quite a long time considered obsolete, and made domestic bus by about 10% more expensive than what is actually large exponent. Last year, production of buses in China produced about 400,000 buses. Not only on appearance but also in the domestic market in China is growing demand for bus services – during the Olympics in Beijing, Chinese cities have begun upgrade bus fleet. Foreign countries also began to show interest in the Chinese coaches.

In China, several major bus manufacturers – Haiger, "Chzhuntun", "First Automobile Corporation, and many others. Even the Russian passengers and drivers familiar to many names. For example, in 2006 in Russia was delivered 40 buses firm Chzhuntun "(in Novosibirsk). A tour of the Golden Ring are conducted on buses, "First automobile. The most attractive factor when buying a Chinese buses is price. The Chinese are also interested in entering the Russian market, so they quickly and flexibly able to adapt to conditions of the client.

The only problem with buying Chinese buses is the inability of buses to the Russian climate, so they have to install some additional modifications, such as heaters, heating systems and the like. And in the winter sometimes there are situations when the bus just will not start. In addition, Chinese and Russian have some anthropological differences, which is also quite problematic in the use of Chinese buses. This also applies to the width of aisles in the cabin, and the height of front doors, and the height of the thresholds – in general, go to the Chinese bus to the Russian people to say the least, uncomfortable.
