Design features of the engine power system The power supply system includes elements of the following subsystems: Pic. 5.19. Fuel supply system: 1 - fuel pipes (plastic); 2 - fuel filter; 3 – an arm of fastening of the fuel filter; 4 – a...
Checking the pressure in the engine power system The main indicator of the health of the engine power system is the fuel pressure in the fuel rail. With insufficient fuel pressure, the following are possible: unstable engine operation; stop the...
Reduced fuel pressure in the engine power system Attention! In the power supply system of the engine with fuel injection, the pressure is 380 kPa (3.8 kgf/cm 2 ). Therefore, it is forbidden to loosen the fuel line connections while the engine is...
Removal and installation of the air filter The air filter is removed to gain access to other units in the engine compartment, as well as if it is damaged. You will need: key «on 10», screwdriver with flat and Phillips blades, pliers. 1....
Removal and installation of the fuel pump If engine power drops, increased noise is heard, or intermittent «howls» while the fuel pump is running, it is likely that the fuel pump has failed. First, check the pressure in the fuel supply...
Fuel pump repair The composition of the fuel pump includes a fuel level sensor, a fuel filter, the electric pump itself and a pressure regulator. All these elements are installed in the bracket and the fuel pump...
Replacing the fuel tank and its filler pipe If fuel leaks from the tank, replace the tank. If the fuel pump screen is often clogged, remove and flush the tank. If a leak is found along the junction of the upper and lower parts of the tank,...
Removal and installation of the throttle assembly Signs of a throttle that is not fully closing can be increased idle speed and increased fuel consumption, but not fully opened - the engine does not develop full power. With these malfunctions, first...
Replacement of the regulator of idling The regulator consists of a two-pole stepper motor and a cone valve connected to it. At the signal of the electronic engine control unit, the electric motor moves the valve, thereby changing the flow...
Removal and installation of the fuel rail The fuel rail is removed to replace injectors and repair the cylinder head, as well as when replacing the rail itself. You will need: hex wrench «by 5», flat blade screwdriver, wrench «at 17» (two)....
Checking and replacing injectors Signs of bad injectors may include: difficult engine start; unstable engine operation; the engine stalls at idle; reduced idle speed of the crankshaft; the engine does not develop full power,...
Throttle Cable Replacement If the throttle valve does not open fully (engine does not develop full power) or closes (increased idle speed), initially try to adjust the throttle cable (see «Checking and adjusting the throttle...
Replacement of components of the fuel vapor recovery system Components of the vapor recovery system (canister, fuel vapor separator, canister purge valve, gravity valve) removed for inspection or replacement when a persistent smell of gasoline appears, caused...
