3.4.3. System of ignition

GENERAL INFORMATION

The system of ignition serves for ignition of fuel mix in cylinders in the fullness of time, depending on the speed of operation of the engine and its loading.

The description of various systems of ignition is given below.

System of ignition of high voltage


This system includes the distributor, the coil and spark plugs. The advancing of ignition is controlled by the ignition distributor.

System of ignition Multec MSTS (Microprocessor – controlled Spark Timing System) – the TsVT models

This system controls both a power supply system, and system of ignition and consists of the distributor of the ignition using Hall's (model C 14 NZ, C 16 NZ) effect or the sensor of provision/speed of rotation of a bent shaft (model C 18 NZ), pressure sensor in an inlet collector, the sensor of temperature of cooling liquid, the oxygen sensor and an electronic control unit of Multec, and also the coil of ignition, the electronic module and spark plugs.

The corner of an advancing of ignition is defined by an electronic control unit.

System of ignition Multec MSTS (Microprocessor – controlled Spark Timing System) – the MW models

This system is similar to system of ignition of the TsVT models with that difference that on some models instead of the distributor of ignition the module of distribution of ignition consisting of two coils of ignition and an electronic control unit is installed.

Advantage of this system is that in it there are no moving parts therefore it is more reliable and practically does not demand maintenance.

System of ignition Motronic M 1.5

This system controls both a power supply system, and system of ignition.

The electronic control unit of Motronic regulates an ignition advancing corner on the basis of information obtained from the sensor of provision/speed of rotation of a bent shaft, the sensor of a stream of air, the sensor of temperature of cooling liquid, the sensor of provision of a butterfly valve, the sensor of temperature of the arriving air and the oxygen sensor.

System of ignition Motronic M 2.5

This system is similar to the Motronic M 1.5 system with that difference that it switched on the ignition distributor with use of effect of Hall and the sensor of detonation combustion of fuel.

System of ignition Motronic M 2.8

This system is installed instead of the Motronic M 2.5 system since 1993 and instead of the distributor of ignition uses the electronic module of ignition.

System of ignition Simtec


This system is similar to system of ignition Motronic, however, uses more electronic sensors and drives for increase in reliability and reduction of necessary maintenance.
