Description of the design of the power system The power supply system includes elements of the following subsystems: fuel supply, including a fuel tank, an electric fuel pump, a fuel filter, a fuel pressure regulator, pipelines and a fuel rail with injectors; air...
Checking the pressure in the engine power system Checking the fuel pressure in the fuel rail of the engine is only possible with a pressure gauge with a set of adapters for connecting to the fuel pipeline. 1. Turn on the ignition and listen: within a few seconds you...
Reducing the pressure in the power system Attention! The fuel in the power system is under high pressure, so it is forbidden to loosen the fuel line connections while the engine is running or immediately after it has stopped. To carry out work on the repair of...
Removal and installation of the air filter You will need a TORX E14 socket. 1. Disconnect the air supply hose from the air filter... 2....and the car body, remove the sleeve. 3. Turn out three bolts of fastening of the air filter. 4. Turn out the last fastening...
Fuel pump replacement If the engine power drops, there is increased noise, or howls are periodically heard during the operation of the fuel pump, then the fuel pump is most likely out of order. Pre-check the pressure in the fuel supply...
Fuel tank replacement If a fuel leak is detected from the tank, it is recommended to replace the tank. If the fuel pump screen is often clogged, remove and flush the tank. It is more convenient to remove an empty tank while working on a...
Checking and replacing the fuel pressure regulator The health of the regulator is determined on a running engine by the fuel pressure in the injector rail (see «Checking the pressure in the engine power system» ). If the pressure is below normal, and the rest of the...
Check, removal and installation of fuel injectors Possible signs of injector failure: difficult engine start; unstable engine operation; stop the engine at idle; increased idle speed of the crankshaft; the engine does not develop full power, insufficient engine...
Removal and installation of the fuel rail You will need: TORX T30 wrench, flat blade screwdriver, side cutters. 1. Reduce the pressure in the supply system (see «Reducing the pressure in the power system» ). 2. Remove the air filter (see «Removal and...
Removal and installation of the throttle assembly You will need a flat blade screwdriver. 1. Disconnect the wire from the terminal «minus» battery. 2. Remove the air filter (see «Removal and installation of the air filter» ). 3. Press the latch... 4.... and disconnect...
Replacement of the regulator of idling The idle speed control is located at the bottom of the throttle assembly. It consists of a two-pole stepper motor and a cone valve connected to it. At the signal of the ECU, the electric motor moves the valve, thereby...
Throttle cable adjustment 1. For visual inspection, remove the air filter (see «Removal and installation of the air filter» ). 2. Check the throttle position: with the accelerator pedal fully depressed (an assistant should do it) it should be...
Throttle Cable Replacement 1. Disconnect the throttle cable from the accelerator pedal. 2. Remove the air filter (see «Removal and installation of the air filter» ). 3. Disconnect the tip of the cable from the intermediate lever. 4. Squeeze the...
Replacement of an adsorber of system of catching of vapors of fuel The evaporative emission system adsorber is removed for inspection or replacement if a persistent smell of gasoline occurs due to a leak in the canister, or if the canister purge valve fails. In addition, a violation of...
Exhaust system design features For Renault Logan cars, the manufacturer installs an exhaust system made as a single element, and supplies its separate parts for spare parts. Between the catalytic converter and the additional muffler... ... and also...
Replacement of elements of release of the fulfilled gases To replace the downpipe and catalytic converter you will need: «on 10», extension cord, caliper, angle grinder with cutting wheel for metal. 1. Measure the distance between marks (it should be 80 mm). Note. Tags are...
