SYSTEMS OF IGNITION OF 4-CYLINDER ENGINES
Backlash check in the engine distributor 4ZD1
On 4-cylinder petrol engines mechanical and electronic contactless distributors of ignition are established. In the contactless distributor the photo-electric gauge providing registration of position of the piston and speed of rotation коленвала
SYSTEMS OF IGNITION OF ENGINES V6
On engines V6 the watching electronic system of ignition (EST) which consists of the battery, the distributor of ignition, the switch of ignition, candles, primary and high-voltage chains is established.
Management of ignition system is carried out from the electronic block of management (the onboard computer – БК
) on which signals from system of the gauges established on the engine arrive. On the basis of signals from gauges BK расчитывет the
optimum moment of ignition also operates the distributor. The optimum angle of an advancing of ignition is defined by system ESC (managements искрообразованием
) which main element is the detonation gauge.
BACKLASH ADJUSTMENT ON THE ENGINE DISTRIBUTOR 4ZD1
On the engine 4ZD1 before installation of the moment of ignition it is necessary to check up and adjust a backlash in the distributor.
| PERFORMANCE ORDER
| 1. Uncover the distributor, a sealing ring and бегунок.
|2. Measure щупом a backlash on a ledge of the induction gauge which should be 0,30–0,50 mm. If necessary adjust.
| 3. Ослабьте screws also move the gauge-shaper before reception of the necessary backlash. Tighten screws and again check up a backlash.
Details of the distributor of this engine are not subject to repair. The failed details replace.
