Car engine power system Lada Priora 1

Features of the design of the engine power supply system
The power supply system includes elements of the following subsystems: Figure 5.19. Fuel supply system: 1 – fuel pipes (plastic); 2 – fuel filter; 3 – fuel filter mounting bracket; 4 – fuel pump...

Checking the pressure in the engine fuel system
The main indicator of the engine fuel system's health is the fuel pressure in the fuel rail. If the fuel pressure is insufficient, the following may occur: unstable engine operation; engine stop at...

Reduced fuel pressure in the engine fuel system
Attention! In the fuel injection engine fuel system, the pressure is 380 kPa (3.8 kgf/cm²). Therefore, it is prohibited to loosen the fuel line connections while the engine is running or immediately...

Removal and installation the air filter
The air filter is removed to gain access to other components in the engine compartment, or if it is damaged. You will need: a 10 mm spanner, a flat- and Phillips-head screwdriver, and pliers. 1....

Removal and installation the fuel pump
If the engine power drops, increased noise is heard, or periodic "howling" sounds are heard when the fuel pump is operating, then most likely the fuel pump has failed. First, check the pressure in...

Fuel pump repair
The fuel pump consists of 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 housing (in the fuel...

Replacing the fuel tank and its filler pipe
If fuel leakage is detected from the tank, replace the tank. If the fuel pump screen often becomes clogged, remove and flush the tank. If a leak is detected along the joint line of the upper and...

Removal and installation the throttle assembly
Signs of a throttle valve that does not close completely may include increased idle speed and increased fuel consumption, while a throttle valve that does not open completely may mean the engine does...

Replacing the idle speed control valve
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 the fuel rail
The fuel rail is removed to replace the injectors and repair the cylinder head, as well as when replacing the rail itself. You will need: a 5 mm Allen key, a flat-blade screwdriver, and a 17 mm key...

Checking and replacing injectors
Signs of injector malfunction may include: difficult engine starting; unstable engine operation; engine stalls at idle; reduced idle speed of the crankshaft; engine does not develop full power,...

Replacing the throttle cable
If the throttle valve does not open fully (the engine does not develop full power) or is closing (increased idle speed), first try adjusting the throttle cable (see "Checking and adjusting the...

Replacement of fuel vapor recovery system components
Fuel vapor recovery system components (adsorber, fuel vapor separator, adsorber purge valve, gravity valve) remove for inspection or replacement if a persistent smell of gasoline appears, caused by...
