In gas-fired generators with four stroke engines, for the combustion to take place, the spark needs to be ignited by the spark plug into the combustion chamber; The generated combustion energy is transferred to the pistons and eventually the engine is driven.
In ground motors, the ignition command is transmitted to the coils and then to the spark plug via the ignition box.
In different generators depending on the model and type of engine, a sensor is mounted on the flywheel and the valve shaft, which, with the starter motor, sends the position of the crankshaft and valve to the ignition controller As a result, the ignition controller uses this input information to send the ignition command at its intended time, after which the engine is tuned in accordance with the algorithm and settings made on the ignition controller and allowed to start and according to the firing order, Sparks in the engine. Failure to do so early or later may cause the ignition to be incomplete or combustion in the exhaust, and the engine will not operate normally.
