11.6.4. System of ignition of the engine of fashion. 3313
The engine is equipped with microprocessor system of ignition (MPSZ).
Characteristic of MPSZ in comparison with classical system is the task of the moment of ignition and management of a corner of its advancing of an electronic way. MPSZ performs also function of the economizer of compulsory idling (ECI).
MPSZ includes: two inductive sensors, one of which registers a certain provision of a bent shaft, and another – its movement; controller (electronic control unit); two two-output coils of ignition, one of which serves the 1 and 4 cylinders (K3 1, 4), and another – the 2 and 3 cylinders (K3 2, 3); the sensor screw for registration of a closed position of a butterfly valve and the electromagnetic valve for shutdown of supply of fuel on the mode of compulsory idling.
In addition MPSZ uses a signal of the sensor of temperature of cooling liquid that ensures functioning of the engine at its insufficient warming up by correction of a corner of an advancing of ignition. Besides, depression size in an inlet collector of the engine for the purpose of correction of a corner of an advancing of ignition depending on loading is considered.
