P p and n p and n d e d a t a turbocharger and I is the following. On the shaft of the turbocharger turbine wheels sit two, placed in two separate buildings. The driving force for the turbine wheels are the exhaust gases of diesel engines. They
scatter the compressor shaft, and as the rotor and the rotor exhaust
fresh air sitting on the same shaft, then with the same turns of fresh
air is injected into the cylinders. The use of a turbocharger increases as the engine power and torque. A
prerequisite for the effective operation of the engine is a certain
shaft speed compressor, which guarantees a good degree of filling. Typically, the motor rotates at a speed not less than 3000 rev / min.The elements of the fuel, clean air and exhaust gas
The fuel tank has a filler neck with strainer and internal partitions to eliminate the sharp movements of the fuel when moving the car. In the fuel cap has steamair cooling valve. In the tank is located Poplavnoi fuel level sensor. Capacity of fuel tanks are usually designed for 500 kilometers. Fuel tanks are made of steel sheet.
The fuel pump is used to feed on the fuel line from the fuel tank to the carburetor. Have fuel pumps in the collapse of the engine or side cover distribution gear. The most widely used fuel pump diaphragm type. The fuel pump is operated directly by the eccentric cam shaft or through the bar, as well as a lever for manual fuel supply. With clash of eccentric rods or pressure on the outer end of the double-arm lever diaphragm pump rod is pulled down, and the injector spring is compressed. Above the diaphragm creates a vacuum under the action of which the inlet valves open pump. Fuel fills the cavity below the diaphragm. When the cam runs away with the external lever arm or a weaker rod pressure, the diaphragm under the action of the spring discharge is returned to its original position. Under the diaphragm creates a fuel pressure under the action of which the inlet valves are closed and the exhaust valve opens. Fuel from the carburetor is forced into the carburetor. To apply the fuel to the carburetor with the engine off, you need to click several times on the lever manual pumping fuel.
Installed on diesel engines fuel pump piston type, which is fixed to the pump. The drive from the eccentric shaft of the pump.
When the piston moves downward under the action of the spring, and above it a vacuum, and fuel is sucked into the cavity. A fuel in a piston, is forced into the trunk to the fuel pump. When the piston moves upward under the influence of eccentric fuel is pushed through the discharge valve in the same line and through the fine filter goes to the fuel pump pressure. The piston is in the pipeline when the set pressure will not move, as the spring pressure on the piston by the piston and the fuel will be the same.
Hand pump is installed on the fuel pump housing. If the engine is not running, using the hand pump can pump up the fuel line. In addition, he is used to remove air from the supply system before starting the engine. High-pressure fuel lines are made of steel tubes. The ends of the tubes are pressed against the cone and cap nuts jacks fittings high pressure fuel pump and injector engine.
Fuel filters installed in addition to mesh type fuel filler cap in the housing and the fuel pump nozzle carburetor float chamber. Fuel from the tank enters the filter sump strainer, which separates the fuel from mechanical impurities and water. Removable filter element filter consists of thin plates. Fuel is cleared, passing through the gap between them. Coarse filter diesel fuel set on a frame vehicle. Major mechanical impurities and water collected in the bottom of the cup, and from the top through a strainer is supplied fuel to the fuel pump.
The fine filter is a ceramic filter element, or a copper grid with a fine mesh, rolled into a roll. Install it in front of the carburetor. In diesel engines the final fine filter cleans the fuel before it enters the injection pump and set at the highest point of diesel power system for the collection and disposal through a special valve-jet air trapped in the system. Each filter section has a paper filter elements.
The air filter is installed on the carburetor, or connected to the carburetor through the air pipe. It consists of a body with an oil bath, cover with the pipe, the filter element and the retaining screw with wing nut. In the inertial-oil filter air passes repeated cleaning.
On cars often install air filter with a dry filter element with two stages of cleaning. The outer layer of non-woven synthetic fibers provides primary treatment, secondary treatment for an internal box made of corrugated cardboard.
To file a combustible mixture in the combustion chamber of engine cylinders are inlet pipes (sewers). In the reservoirs is a complex system of canals, which are designed for the distribution of the combustible mixture from the mixing chamber carburetor to the cylinders. The space between the channels of the reservoir communicates with the cavity cooling the cylinder heads. Thus, the intake manifold is heated in order to better vaporization of fuel. Fiber or cardboard gaskets are gaskets in the joints. To remove exhaust gases from the cylinders of the engine exhaust pipes are used (collectors). They are made separately for each cylinder and fastened to the outside of the cylinder heads. As the sealing gaskets used metalloasbestovye.
To reduce the exhaust noise is the muffler. It is a cylinder which is placed inside a tube with many holes and multiple partitions. The cylinder can be made with a double layer teploshumoizoliruyuschey. The muffler is connected to the exhaust manifold heat-resistant steel tubes.
