THE GENERAL DATA

The Block diagramme of control system ESC II

The control system of preparation of a fuel mix of the carburettor and ignitions ESC II includes the electronic block of management, the ignition coil, the distributor of ignition with the built in gauge of number of turns of the engine, a spark plug and gauges of temperature of a cooling liquid, depression in an inlet collector and neutral position of the lever of the selector of an automatic transmission.

The electronic block of management of system ESC II operates fuel system and ignition system simultaneously that promotes reception of the maximum capacity and profitability of work in all range of loadings of the engine.

The electronic block of management of system ESC II receives signals from gauges and on the basis of the received information the block operates pressure giving on a primary winding of the coil of ignition and interruption of a current and depending on a corner of an advancing of ignition which is defined on the basis of the information from gauges, submits a high voltage impulse through the distributor on a corresponding spark plug and makes ignition of a fuel mix in the cylinder. Depending on the information received from gauges constant change of time intervals of giving and switching-off of a current from a primary winding of the coil of ignition therefore change of a corner of an advancing of ignition in relation to an initial corner of installation of ignition is made is made. Also on the basis of a signal from the management block heating of the inlet pipeline and management of turns of idling of the engine is made.

All works connected with check of work of knots of system ESC II, it is necessary to make on the special equipment at servicing deport.

If there is an error in any of the data received from the gauge, system ESC II is included into a way of the doubler. In this case, system ESC II ignores a wrong signal of the gauge, and accepts preliminary programmed value which will allow the engine to continue work (though and with smaller efficiency).
