2.1.7.3. Ignition coil

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 pairs). Two secondary conclusions contain positive and negative conclusions of secondary windings. The closed contour of secondary windings consists of the 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)
