We know that the automobile engine idle speed value lower than or exceeding the prescribed range, will appear stage flameout, speed instability phenomenon. Today,TRV Throttle Body is for the engine idle speed how to deal with you under the guidance of.

1, idle instability.

Idling instability manifested as: idle when the engine speed is not uniform, trembling.TRV Throttle Body to remind the reasons are: idle air hole plug, idle speed device working poor,individual cylinder spark plug spark is too weak, the individual valve seal is not strict,intake manifold air leakage, ignition time early or too late, idle improper adjustment.Engine idling instability, should first adjust the idle speed, such as idle adjustmentafter the failure still can not eliminate, should check whether blocking the idle hole andidle air hole, such as the amount of available pore clogging, petrol or acetone wash and use compressed air blowing through; such as hole is not blocked, should be theengine speed stability at a certain speed, listen to the intake manifold and carburetor,lower gasket is leakage, such as leakage phenomenon, the fastening screws,reducing available or shim method to exclude. Such as the phenomenon of unstable idle speed accompanied by reduction of engine power, should be sealed performance further check the spark plug valve working condition, and the ignition timing is correct,if necessary, adjust the maintenance.

2, identify idling bad.

The normal work of the engine, should be of uniformity in the 300-500r/min speed range operation. If the engine is the lowest stable speed exceeds the speed range, or in the speed range of the engine flameout occurs, speed instability, is no idle or idling bad. Idling bad, according to the fault characteristics will be divided into idling flameout, unstable idle speed and idle speed is too high. If after starting the engine,from low speed to high speed turn good fortune, but a release the accelerator pedal immediately after flameout, or first running unsteadily and flameout, for idling flameout fault. If the engine idling instability, the exhaust pipe "process, a sudden" sound,generally for idling instability fault. If the engine is the minimum stable speed higher than the specified range, and can make the rotational speed is reduced, for idle speed is too high or no idling fault.

3, adjust the idle speed.

Adjust the idle work, must be carried out at normal temperature, engine valve clearance is appropriate, the ignition system is normal, the pipeline sealing good,choke, solar term door open to closed tight, under normal conditions. Adjustmentscrew out, first solar term door opening adjustment screw, so that the engine to achieve the minimum stable speed. Then use the screwdriver into the idle adjustment screw, when the engine is shut off, then slowly screwed out of idle adjustment screw,so that stable operation and achieve high speed engine. Then the solar term dooropening adjustment screw rotation, the rotation speed of the engine can be reduced to the lowest old. Then adjust the idle speed adjustment screw, so that the engine speed increase. So repeatedly, until the solar term door opening minimum, the engineruns at the minimum stable speed. Finally, to increase speed and suddenly closedsolar term door, not to engine flameout is still turning is appropriate.

Approach 4, idling flameout

Engine idling flameout, should according to the actual situation of idle adjustment.After the adjustment, if the fault disappears, is the improper adjustment of idle screw.After the adjustment, such as fault can disappear, the solar term door a little, to keep the engine running, check with cotton or paper, carburetor, intake manifold gasket isleaking, if not leak, detachable idle orifice are examined, and at the same time, the blowing of idle oil pipe, and then reassembled test, then if the fault disappears,illustrate the idle hole and idle oil pipe plug. Idling cut-off valve for a carburetor,should also check whether the idle valve solenoid circuit is normal, if it is idling oil saving orifice is blocked due to the electromagnetic coil circuit is not normal, the idle stop valve repair.

Approach 5, idle speed too high

Engine idle speed is too high, should start the engine, and then hand control solar term door arm, make Cairo solar term door closure. So when the idle speed is normal,as the solar term door spring too soft, replace the spring. Such as hand control closedsolar term door is invalid, it should check the solar term door is loose or solar termdoor are closed tightly, such as valve closure lax or solar term door loose, should betrimmed; if the Throttle Body is normal, you should check solar term door below is a slight leakage, as should eliminate the leakage phenomenon, if there is no response to idlefor further adjustment, until the appropriate date idle.
