Check the operation of the centrifugal regulator ignition

Immediately after installing the ignition to check the functioning of the centrifugal regulator ignition timing, which is responsible for the dynamics of dispersal of the car. Before checking it is necessary to remove the tube from the vacuum regulator timing, as the centrifugal and vacuum regulators are tested separately. To check the engine running smoothly to press the gas and thus follow a blinking light strobe for mobile label TDC (TDC) on the crankshaft pulley or flywheel. With increasing engine speed label should move smoothly on the pulley in the direction of the ignition, while reducing the speed to idle again to return to his seat. For efficient operation of the engine required a strict correspondence between the number of revolutions and POPs (ignition timing). Any value of engine speed corresponds to a value of ignition. Only the exact correspondence of these values ??can drive to demonstrate their maximum potential. Each engine has its own relation between the ignition and the number of revolutions. Centrifugal regulator device allows you to adjust the change plugs, adjusting it for the engine speed. Bending springs holders, you can change the force with which the weights act on the ignition. To fine-tune the centrifugal regulator is necessary to use background information on the motor. For example: speed POPs 800 10 1200 15 1600 20 2500 35 Irregularities of the centrifugal regulator greatly affect the power and engine efficiency. There are a number of malfunctions that often occur. For example, a complete jamming of the mechanism - derived from the lack of lubrication. This is reflected in the fact that the mobile mark TDC is in place at higher engine speeds. Check prizvoditsya strobe when off-hook to the vacuum regulator! This little problem can reduce engine power to 40%. Eliminated by jamming a complete disassembly of the distributor of ignition, cleaning and lubrication of moving parts. Another problem of the centrifugal regulator is to weaken the tension springs. In this case, even a small increase in speed, mobile label TDC immediately flies to the very early ignition, and while driving ever heard detonation knocking. Installing a later ignition detonation can remove, but lost dynamics of dispersal, increases fuel consumption. This problem is eliminated by replacing the weak springs in the more tight. All these faults are observed in the normal installation POPs at idle. In addition, there is another problem - a strong vibration or frequent, rapid movement of the TDC mark on idle. Vibration occurs without an increase in turnover, while there may be uneven idle. The label is arbitrary ranges of ten degrees. This is due to increased bearing wear in the distributor or is a big gap at the junction with traction control vacuum breaker plate.
