The air entering the engine cylinders is cleaned of dust by an air filter. Air filter mounted in the engine compartment on three rubber mounts. The filter element of the filter is replaceable, made of special paper. To prevent the ingress of polluted air into the intake tract, there is a sealing border at the top of the element. To replace the filter element, the filter cover is made removable. The purified air passes through the mass air flow sensor through the air duct to the throttle valve.
throttle valve regulates the amount of air entering the engine cylinders. Pedal damper drive "gas" cable. The damper rotates on an axis in the housing (branch pipe). The throttle body is studded to the receiver flange. The housing has a channel for the coolant. The channel is connected to the cooling system by rubber hoses. The circulation of coolant through the throttle body prevents freezing of the internal air cavities of the body in winter. Fittings are installed in the housing for connection with the absorber and the engine crankcase ventilation system.
The throttle body, with the throttle position sensor and idle speed controller mounted on it, form throttle assembly.
Throttle assembly: 1 - throttle actuator sector; 2, 4 - fittings for connection with the engine cooling system; 3 - crankcase exhaust fitting; 5 - throttle position sensor; 6 - idle speed regulator; 7 - fitting for connection with the adsorber; 8 - throttle valve; 9 - branch pipe of the throttle body
Air is supplied to the intake valves of the engine cylinders through receiver and intake manifold.
Fuel tank steel, welded from two stamped parts. The tank is suspended from the bottom of the car on two steel clamps. The filler neck of the fuel tank is displayed on the right side of the car and is closed with a stopper. Fuel from the tank is supplied by an electric submersible fuel pump.
The pump is installed in the fuel tank. To access the pump in the bottom of the car, under the rear seat cushion, a hatch with a cover is made. A strainer is installed on the fuel pump inlet pipe to trap small solid particles of debris that have entered the fuel tank along with gasoline. The pump is switched on by the ECU.
Fuel pump: 1 - protrusion for attaching a mesh filter; 2 - fuel intake pipe for connecting a strainer; 3 - body; 4 - electrical connector block; 5 - day off (forcing) branch pipe for connection with the cover of the fuel module with a corrugated tube
From the pump to the corrugated tube of the fuel module (see below) gasoline enters the fuel line and then to the fuel filter, where the fuel undergoes a more thorough cleaning.
Fuel filter - paper, installed in a metal non-separable housing. The purified fuel enters the fuel rail through the fuel line.
Engine fuel filter 11183 (1,6i): 1 - inlet pipe; 2 - body; 3 - fuel flow direction arrow (painted on the filter body); 4 - outlet pipe
Note. Fuel filter engine 2111 (1,5i) has threaded fittings.
The fuel rail holds the four injectors and delivers fuel to them. The connection of the ramp with the nozzles is sealed with rubber rings.
The fuel pressure regulator is a bypass valve that maintains in the system (fuel line) operating pressure required for the correct operation of the injection system.
All cars of recent years of production are equipped with a fuel vapor recovery system (in accordance with the environmental requirements of EURO II), where the over-fuel space of the tank is connected with the atmosphere not directly, but through the elements of this system. The system consists of a separator, a safety valve, an adsorber, a gravity valve, an adsorber purge valve, a check valve, connecting pipes and hoses. The separator and gravity valve are fixed under the right rear fender of the car. Gasoline vapor is partially condensed in the separator and returned to the fuel tank. The gravity valve prevents fuel from escaping from the tank when the vehicle is overturned. Safety (two-way) the valve prevents the formation of excess pressure of fuel vapors in the tank, as well as the occurrence of vacuum there caused by fuel consumption.
The location of the elements of the fuel vapor recovery system in the rear of the car: 1 - safety valve; 2 - separator; 3 - plug of the filler neck of the fuel tank; 4 - gravity valve
Note. Pictured is the rear bumper.
From the separator, uncondensed gasoline vapors through pipes and connecting hoses enter the adsorber, which prevents vapors from entering the atmosphere. An adsorber is a container where gasoline vapors are absorbed by activated carbon. When the engine is running at a high crankshaft speed, the ECU sends a signal to open the canister purge valve, and gasoline vapors are sucked into the intake module receiver.
Adsorber: 1 - adsorber body; 2 - branch pipe for connecting the internal cavity of the adsorber with the atmosphere; 3 - adsorber purge valve; 4 - connecting branch pipe of the valve; 5 - adsorber connecting pipe
