Ignition system — specifications

Characteristics of the ignition timing of the ignition distributor Bosch engine 1.1 dm³

The Bosch contact ignition system consists of a battery, an ignition coil, an ignition distributor with an interrupter and spark plugs. Ignition order: 1–2–4–3. The color code is white.

Distributor

brand	Bosch
Drive unit	from the camshaft
Direction of rotation of the rotor	counterclockwise when viewed from above
Gap between breaker contacts	0.4 - 0.5 mm
Breaker contact closed angle	48 – 52°
Capacitor capacity	0.2uF

Initial ignition timing

Engine code	Ignition timing up to TDC (2°)
	Ethyl. Super	Unleaded
GSG	6	2
JLA	6	2
JLB	–	2
JBA	15	15
JBB	7	7
GLB	12	12

Attention! During the test at the stand (ignition distributor removed) engine speed must be reduced by half. When checking the distributor installed in the car, it is necessary to add the value of the initial ignition timing to the ignition timing value.
