The diagram of power supply system of gasoline engine
To eliminate the possibility of engine operation with through- uniformly high rotational speed of a crankshaft, in six- the theme of the power limiter frequency of rotation Ko lentulo shaft. All of the devices of the power supply system of the engine are connected steel tube — fuel lines. The carburetor is used for mixing Melchi- large particles (or vapors) of gasoline with the air — combustible mix si. This process is called carbonaria. A simple carburetor consists of: • float chamber with float and needle clusters pan; • chamber of the dispenser; • inlet air damper; • mixing chamber with a diffuser; • throttle. In a fuel cell is a device control tion of fuel supply, composed of a float and holicha- the valve. In the mixing chamber made in the form pipe, a tapering neck of the diffuser, in which Rui entered the tube from the float chamber on the spray. From the float chamber atomizer has a touch- action (a specific section and shape) hole- Stia — jet. The diffuser is located below the throttle flap. The action of the carburetor is based on the principle of polveri- tion. The air passing at high speed over Thor- CMA tube submerged in the liquid creates a vacuum, as a result of which the liquid rises in the tube and under the action of a jet of air is sprayed. From the tank the fuel pump the gasoline is served in the swim. - on the camera, the level of which is supported with assistance using a float needle valve. When filling in placeway chamber with fuel the float rises, pressure on the valve, stopping the access of fuel. At idle the engine is the fuel level remains at the same level. When the cycle of a start-up in the intake tubing creates a time- regenia and air stream enters the mixing Cham- Roux carburetor. The narrowing of the cross section of the pipeline Diffuso- rum provides increased airflow and rsrage- tion at the upper end of the nozzle. Due to the difference in pressure tions in the float and mixing chambers, fuel you- assume a spray bottle and sprayed and mixed with the air, forming a combustible mixture. The number of podavai- my fuel mixture in the combustion chamber is regulated by Polo- cutting the throttle or increase the number revolutions of the crankshaft. The level of fuel in Poplavko- the howling of the chamber is reduced, and with it falls popla- wok, giving access to the fuel. A simple carburetor does not provide change the air-fuel mixture when changing the operation mode engine. Modern carburetors are of the device and system that addresses the shortcomings of the simplest car- buretor. |
