The cylinder block is the backbone of the internal enginecombustion, as it contains all the most important components and assemblies of the engine. It is this part that accounts for the bulk of the loads (up to 50 percent). Therefore the block of cylinders (VAZ 2114 including) should be made of the most durable and wear-resistant steel, on special high-precision machines.
This mechanism performs several functions at once: it is the basis for the hinged parts of the motor (cylinder head, crankcase, etc.), and also serves as a housing for housing all engine parts.
Most modern carsmanned by cast-iron blocks of cylinders. Cast iron is diluted with nickel and chrome additives, making it durable and wear-resistant. The main advantages of this material are its resistance to overheating and stiffness, which is necessary at a high degree of forcing the motor. The only drawback of the cast-iron block is its heavy weight, due to which the dynamics of the car significantly deteriorates. To accelerate the car to the required speed, the engine has to produce more power, and this, in turn, entails an increased consumption of gasoline. But, as a rule, the car loses not more than 1-2 percent of the total amount of fuel consumed.
Алюминий является менее популярным материалом для manufacture of these products. A striking example of the use of aluminum blocks are domestic GAZel and some Zhiguli models. The main advantages of this material are its light weight and the best cooling properties. However, along with this motorists note the problem with the search for the necessary material from which the cylinder is made.
The design of the cylinder block assumes the placement of the following parts:
And now more about these devices.The engine cylinders include special sleeves that can be pressed directly into the cylinder block (most often in aluminum devices) or be removable (in the case of a cast iron mechanism). In turn, removable tools are divided into "dry" and "wet".
ГБЦ представляет собой комплекс деталей, которые located at the top of the device. The head of the unit includes a cooling jacket, lubrication channels, as well as candle holes (if it is gasoline) and injectors (if it is a diesel engine). Also in the cylinder head there are openings of the intake and exhaust valves. Between the head and the unit itself there is a small connecting gap in which the gasket of the cylinder block is located. If the engine is not replaced in time, the engine begins to lose its power and traction, while increasing the risk of failure of other parts.
Carter is the main component of thisparts, like a cylinder block. It is a casing for a cantilever. From below, the crankcase is fixed with a special pallet. Regarding the engine block, the internal combustion engine is located at the bottom.
