The ignition system of the gas turbine is obviously different from the diesel generator. The ignition advance angle is a particularly important basic parameter. In gas turbine operation， accurate ignition timing parameter is one of the necessary conditions to achieve accurate ignition of the unit. Weichai diesel engine parts below we take a look at the ignition timing of gas turbine ignition adjustment is what.
    The top dead center is aligned with the flywheel scale "o" at the end of the first cylinder compression， the oscillographic paper is placed around 600 degrees around the flywheel o scale and marked on the paper with the same degree as the flywheel scale， One cylinder of high-voltage cable， one end of the ignition coil is inserted into the output， the other end is placed on the tip of the flywheel pointer， the exposed wire and the oscilloscope paper about 2-4mm， and then use the starter motor to drag the engine rotation， then high-pressure cable exposed Between the wire and the oscilloscope paper sparks， and the oscilloscope paper breakdown， stop starting the motor， remove the oscilloscope paper， press the spark breakdown position， you can determine the ignition advance angle.
    Diesel engine parts found ignition timing and does not match the specified value， can be precisely adjusted. The method is as follows: Loosen the two screws of the magnet motor and the actuator， and the magnet motor can rotate along the drive shaft. Magneto motor to the free end of the middle position to the maximum position， the ignition advance angle lag about 10 degrees crank angle. On the contrary to the output to the maximum position， the ignition advance angle about 10 degrees crankshaft angle. According to the actual measured the size of the advance angle， according to a certain direction to adjust， adjust and then use the drag method， repeatedly check the ignition advance angle， until adjusted to the specified value.
Diesel engine parts through the above method can determine the exact value of the ignition advance angle， with particular attention to the use of drag method to check the ignition advance angle， the gas valve should be closed to ensure that the gas genset in the starter motor drag On fire.
