Check the air intake system with drosselirova Niemi before the valve for engines designed to run on the lean mixture composition

Check the air intake system with drosselirova ¬ Niemi before the valve for engines designed to run on the lean mixture composition
(4A-FE (AT190 and AE101) and the 4A-GE (AE92, AT160 and ASH11))
1. Warm up the engine to normal operating temperature and muffle it.
2. Connect the tachometer to the engine (see "Adjusting the timing advance for ¬ bandits").
3. With the tee, connect the gauge to the hose between the valve "off" depression and executive ¬ tive device.
4. Check the presence orabsence of depression at various engine operating modes:
a) Start the engine.
b) Verify that the mode of the normal idle speed gauge shows the presence of significant depression.
c) opening the throttle, increase the frequency of rotation of approxi-mately:
up to 4350 min - (4A-OE for models with 3-component neutralization ¬ torus exhaust gas) to 5000 rpm (4A-OEdlya models without the three-component neutral-mash of exhaust gases); • up to 4200 min-1 (4A -PE), and make sure the vacuum gauge, show the absence of dilution (0).
1. Warm up the engine to normal operating temperature ¬ Noah.
2. Shut off it.
3. Disconnect the connectors distribu ¬ telya (or integrated unit beskon-stroke ignition systems).
4. (For 4A-DE) Disconnect the spark plug guard.
5. (For 4A-OE (AE92, ASH11, AT160) 4A-FE and (except for AE101 and AT190)) Disconnect the injector cold engine start ¬ Nogo.
6. Disconnect the high voltage pro ¬ water from spark plugs, keeping them for rubber tips (see "Checking the high-voltage wires").
7. Remove the spark plug, use ¬ Zuya special 16-mm key candle.
8. Check the compression in the cylinders.
a) Set the candle in hole compressometer.
b) Fully open the throttle.
c) Turning the engine start ¬ rum, measure the compression. .
Please note: the battery state ¬ Noah battery should provide a crankshaft rotation about an hour ¬ quency not less than 250 rev / min.
d) Repeat paragraphs "a" - "in" for the rest of the cylinders.
Note: Measurements should be made for an extremely short period of time, because when hit Lebanon in the top ¬ ¬ catalytic neutralization of the torus, may be damaged. Compression: Rated: R-4A, 4A-FE
and 7A-FE. 1320 kPa (13.5 kgf/cm2)
5A-PE. 1370 kPa (14.0 kgf/cm2)
4A-OE:
ASH11, AT160 and AE92 early starts .... you ¬ 1236 kPa (12.6 kgf/cm2) AE92 later editions
Compression check
1314 kPa (13.4 kgf/cm2)
2. Measure the resistance between the valve system UUT. Intentional impedance
(20 ° C) 11-13
Note: If the 4A-FE ¬ tained intended for continuous operation on a non-leaded gasoline (when using 3-component neu ¬ exhaust gas analyzer), the gauge will show the lack of dilution at speed menee4200ob/min.
Check Valve System UUT (only 4A-GE (AE101, AE111)
Checking the engine
1. Warm up the engine to operating temperature (80 ° C).
2. When running at idle the engine, disconnect the cluster of pan ¬ UUT.
3. Apply the findings of the valve voltage-tion of the battery (for 30 sec.) And make sure the idle speed becomes unstable ¬ becomes.
4. Make sure the voltage is lost in the connector ¬ tion valve of the harness, with a sharp increase in NII ¬ speed from idle up to 6000 rev / min (throttle fully open).
5. Connect the valve.
Checking the valve 1. Apply the findings of the valve system ¬ we UUT voltage from the battery (for 30 sec.) And make sure that the valve
moves.
If the resistance is different from the specification, replace the valve.
AE101, AE111
1330 kPa (13.6 kgf/cm2)
Minimum:
4A-BE (AE101, AEG1)
1080 kPa (11.0 kgf/cm2)
Other
981 kPa (10.0 kgf/cm2)
The value of compression for various chi ¬ Lindrum should not differ ¬ bo by over 98 kPa (1.0 kgf/cm2). e) If the pressure in one or several cylinders ¬ less, per ¬ pour a small amount of mo ¬ tor oil into the cylinder through the hole a candle and repeat the opera ¬ radio points "a" - "c" for cylinder ¬ ditch with low compression.
• If the addition of oil increases ¬ Vaeth compression, it likely means wear or damage to the rings and / or liners.
• If the pressure remains low, which means loosely fit the valve seat, or stuck valve or a violation of Germany ellipticity cylinder head gasket.
9. Install the spark plugs (MZ = 18 Nm).
10. Connect the high voltage wires to the spark plugs.
11. Connect the distribu ¬ telya or an integrated unit of ignition ¬.
12. (For 4A-GE) Install the oil guard spark plugs.
13. (For 4A-4A-CE and the PE (except the AE101 and AT190)) Connect fsrgunm cold engine starting.
