Devices fuel supply, air cleaning
and exhaust Vyshtampovyvajut fuel tank made of sheet steel, has the filler neck with mesh filter and internal partitions to eliminate sharp move- ments of the fuel during driving of the vehicle. In traffic for- one neck has a vapor valve, the action which is similar to the action of the valve in the air cooling system make- tion of the engine. The tank is a float sensor level AE fuel. The fuel tanks usually looked tan 400-500 km of run of the car. Fuel filters mesh type are installed in addition to the filler neck in the housing lid top one of the pump and the fitting of the float chamber carburator- pa. The fuel from the tank enters the filter tank coarse, where the fuel is separated mechanical impurities and water. Its removable filter element state it from thin plates. The fuel is cleaned by passing through the gap between them. The coarse filter diesel top Liwa (Fig. 42, in) is mounted on the vehicle frame. Cereals- nye mechanical impurities and water collect in the cha- STI Cup, and from the top through the strainer serves the fuel priming pump. The fine filter has a ceramic- cue filter element or copper wire set ku rolled into a roll. Install it before carbureto- rum. In diesel engines the filter of thin clearing final tive cleansing the fuel before it enters the injection pump and installed at the highest point of the power system diesel for collection and removal through a special valve, putt- Lehr caught in the air. Each section of the filter has a paper filter elements. The fuel pump serves to feed fuel- doprovodu gasoline from the tank to the carburetor. Are fuel pumps in the collapse of the engine or side covers timing gear. The greatest distribution got the fuel pump is of diaphragm type. Fuels- tion pump is driven directly from the ex- the teat of the Cam shaft or through the post, as well also a lever for manual fuel feeding. When RAID- the research Institute of the eccentric or the pressure rod on the outer end two shoulders of the lever of the pump diaphragm stem is drawn down, and discharge the spring is compressed. Over diaphrag- my creates a vacuum that open are the intake valves of the pump. Fuel fills the cavity above the diaphragm. When the Cam escapes from the outer plait is cha of a lever (or weakens the pressure of the rod), the diaphragm under the action of a pressure spring returns to Exodus tion position. Above the diaphragm is pressurized Topley- VA, under the action of which closes the inlet valves and opens the exhaust valve. Fuel from the pump displace varies in the carburetor. The diaphragm is made from rubberized or varnished cloth- Noah tissue valves — from benzokolonki rubber, and their spring — from bronze wire. Injection pru- Gina made of spring steel, the casing is made of Alu- minium alloy. To feed fuel to the carburetor at idle the engine must repeatedly press the lever-handles Noah pumping of fuel. On diesel engines is installed fuel pump is piston type, attached to the fuel pump. Drive provides- by eccentric shaft of the pump. When the piston moves down under the action of the spring over it creates a negative pressure and is sucked Topley- VA into this cavity. At the same time, fuel under the piston is displaced in the line to the injection pump. When motion the research Institute of the piston upwards under the action of eccentric fuel you- stalkivaetsya through the discharge valve in the same master's degree. - RAL and through the fine filter goes to the fuel the high pressure pump. When reaching into the trunk set pressure, the piston does not move, as the pressure of the spring above the piston and fuel under long- SNAM will be the same. |
