The vintage Soviet automobile coil of ignition B17, also known as the "B17 coil," was a commonly used component in Soviet-era automobiles manufactured in the mid-20th century. This ignition coil was used in a variety of different Soviet-made cars, including the Lada, Moskvich, and ZAZ.

The B17 coil is a type of transformer that converts the low voltage from the car's battery into the high voltage required to create a spark in the engine's spark plugs. It is made up of two windings of wire wrapped around a core of magnetic material. The primary winding is connected to the battery, and the secondary winding is connected to the spark plugs.

The B17 coil is known for its durability and reliability, and it was widely used in Soviet-era automobiles due to its low cost and availability. However, it can be difficult to find replacement parts for the B17 coil today, as many of the original manufacturers have ceased production.

Overall, the B17 coil is an interesting artifact from the Soviet-era automotive industry and serves as a reminder of the unique technological innovations that were developed during this time period.
