15.8. Corner of an advancing of ignitionSystem of ignition of EZL The system of ignition of EZL works at the basis of the signal received from the sensor of an angle of rotation of a cranked shaft. The system of ignition establishes a demanded corner of an advancing of ignition on the basis of information on engine turns, the provision of a cranked shaft and depression in the inlet collector, received from the sensors established on the engine. Distinctive feature of system of ignition of EZL is that it is impossible to adjust the initial moment of an advancing of ignition by turn of the case of the distributor concerning a shaft. However the initial corner of an advancing of ignition can be changed depending on type of used fuel. For this purpose it is necessary to change the provision of a switching cap in a nest of the fine tuning, located in a motor compartment near the ECU block. In a switching cap resistors of various resistance are established. The cap can be established in some provisions according to labels on a cap. Depending on what resistor of a cap is connected at present to nest contacts, the ECU block of system of ignition increases or reduces an initial corner of an advancing of ignition with a step in 3 °. It is possible to measure a corner of an advancing of ignition also, using a stroboscope. System of ignition of TFZ The system of ignition of TFZ copes the sensor of impulses established in the case of the distributor of ignition. In this case the initial corner of an advancing of ignition can be adjusted by turn of the case of the distributor concerning a shaft.
