Fig. 2.70. Ignition coil: 1 – the ignition coil – the top view; 2 – secondary conclusions; 3 – the ignition coil – a side view; 4 – ignition coil; 5 – PCM block
The coil of ignition has two windings. For cylinders 1 and 4, and cylinders 2 and 3 respectively (the coordinated couples). Two secondary conclusions contain positive and negative conclusions of secondary windings. The closed contour of secondary windings consists of high-voltage wires, two spark plugs and a head of the block of cylinders. Thereof, one coil ensures functioning of two cylinders. The impulse of ignition is generated by the built-in system of ignition of the PCM block (fig. 2.70).
