1.1.4. Correction of a corner of an advancing of ignition


Fig. 1 — 3. Octane proofreader: 1 — the case; 2 — an octane proofreader; 3 – nut

At operation of the car, sometimes depending on quality of the filled fuel there is a need to correct an ignition advancing corner. The moment of ignition is corrected an octane proofreader 2 (fig. 1 — 3) the ignition distributor, allowing to reduce or increase an ignition advancing corner. The signs "+" (advancing) and" –" (delay), put on a scale an octane proofreader, specify the direction of its rotation.
You carry out correction of a corner of an advancing of ignition on the heated-up engine. Before adjustment note position of average risks an octane proofreader on the block of cylinders. At movement along the flat road on direct transfer with a speed of 50 km/h sharply press an accelerator pedal. If at the same time there is an insignificant and short-term detonation, then the corner of an advancing of ignition is established correctly. At a strong detonation (early ignition) weaken a nut 3 (see fig. 1 — 3) and turn the case 1 on 0,5–1 division clockwise (on "-"). In case of lack of a detonation (late ignition) turn the case 1 on 0,5–1 division counterclockwise (on "+").
After adjustment tighten a nut 3 and check correctness of the moment of ignition at the movement again.
