Turbine Engine Ignition Systems Since turbine ignition systems are operated mostly for a brief period during the engine-starting cycle, they are, as a rule, more trouble-free than the typical reciprocating engine ignition system. The turbine engine ignition system ... need to be timed to spark during an exact point in the operational cycle. It is used to ignite the fuel in the combustor and then it is switched off. Other modes of turbine ignition system operation, such as continuous…

Igniter Plugs 1. Disconnect ignition leads from igniter plugs. A good procedure to perform before disconnecting the ignition lead is to disconnect the low-voltage primary lead from the ignition exciter unit and wait at least one minute ... permit the stored energy to dissipate before disconnecting the high-voltage cable from the igniter. Figure 4-78. Flashover inspection. 2. Remove igniter plugs from mounts. 3. Inspect igniter plug gap surface material. Before inspection, remove residue from…

Chapter 4: Engine Ignition & Electrical Systems Reciprocating Engine Ignition Systems The basic requirements for reciprocating engine ignition systems are similar, regardless of the type of engine. All ignition systems must deliver a high-tension spark across ... electrodes of each spark plug in each cylinder of the engine in the correct firing order. At a predetermined number of degrees ahead of the top dead center position of the piston, as measured by crankshaft travel in degrees…
