Check and adjust the speed and composition of the mixture at normal idling mode

Check and adjust the speed and composition of the mixture at normal idling mode.
Note: under "normal holo ¬ by simple move" refers to the engine idling at minimum an hour ¬ quency of rotation, which is defined specifications.
Prerequisites for the pro-conducting checks and adjustments. Note: 4A-5A-P and P the external inspection, make sure it ¬:
• The reliability of the mounting carbo ¬ operator and the intake manifold.
• In the absence of significant congestion of tie rods and superfluous-abacklash to the axis of the throttle-slonki.
• In the presence of pins.
h) Ignition Timing of correct adjusted.
• The fact that the level of fuel in the float chamber - normal (on the control line to see the glass-tion).
All other events are ¬ Xia, usually common to all engines.
a) The engine warmed to normal operating temperature.
b) The air filter is installed.
c) All pipes and hoses, air intake system installed in its place.
d) All consumers of electricity are turned off (except ignition systems and engine electronic fuel injection).
e) All vacuum lines are connected properly (including hoses EGR-Shih gases).

a) small electrical systems of cooling off (or should not be included when checking), l) calibrated tachometer, Provo ¬ ren to be compatible with the data engine and properly connected to the engine (see "Regula ¬ renormalization ignition timing"), m ) (Just to test the concentration of CO or CO and ND) Gazoana-stabilizer of CO / CH calibrated 2. Check the speed of a normal idle speed.
a) Start the engine.

d) opening the throttle, increase the speed of the motor shaft to the 2500 - 3000 min "and hold the engine in this re-bench for 60 - 90 seconds, then release the throttle.
e) Measure the speed of a normal idle speed (if you're of Prisoners the fan) and compare the result with the value of ¬ eat, see table.
e) If the speed of the normal engine idle does not meet the conditions ¬ holes, adjust it.
