Ignition controller with internal Idle economizer control unit 1103.3734

General information:

The ignition controller with internal idle economizer control unit (IECU) 1103.3734 is purposed for operation in contactless ignition systems and they ensure uninterrupted spark formation in the operating frequencies range of crankshaft rotation and also switching on / off of idle economizer electromagnetic valve in order to increase fuel saving and reduce toxicity of vehicle exhaust gases.

Application: automobiles “Slavuta”, “Tavria” since November 2001 year of manufacture, “Daewoo Sens” with carbureted engines.

The units operate together with the ignition coil 40.3705, 27.3705 or any other with analogous parameters and is controled by a signal of Hall effect sensor, built-in in the allocator with the input ratio from 1,3 up to 1,6.

According to requirements to ignition systems, ignition controller ensures Hall sensor protection against overvoltage by stabilization of voltage fed to the sensor

The unit is produced in single climatic design O2.1 in accordance with GOST 15150 for internal market and for export. It is designed on a single-wire power circuit, the unit housing is connected to the vehicle housing. An operating mode of the unit in accordance with DSTU GOST 3940 is continuous nominal S1.

The ignition controller with internal Idle economizer control unit 1103.3734 is installed in its intended place in the car using standard fasteners and a standard connector. When installing the blocks, it is necessary to ensure reliable contact of the radiator of the block with the car body.

The unit plug is analogous to plugs of ignition controllers 3620.3734, 3640.3734, 0529.3734, 0729.3734. The outputs are designed in such a way that it is permitted the use of the unit instead of the ignition controller on automobiles where ignition controllers 3620.3734, 3640.3734, 0529.3734, 0729.3734 and other are applied. Thus control functions of internal idle economizer control unit are performed by the standard IECU and the unit performes only functions of the ignition controller. For this aim it is necessary to connect pins 2 and 3 of the standard ignition controller plug.

The warranty period of exploitation is 3 years from the date of commissioning or from the date of sale in retail commercial network. The warranty obligations of the manufacturer are valid during four years from the date of the item production. The date of production is marked on the case of the item housing.
