System brain
The management block
Management of ignition and injection is united in one electronic block. Installation of the moment of ignition in the same place pays off.
- At the disposal of the management block there is all possible data and engine characteristics. It is provided with the gauge of the Hall or the gauge of number of turns of the engine and position коленвала, and also gauges of temperature of the engine, position throttle заслонки, etc.
- If to express an ignition corner (the ignition moment) by means of a loading condition on the engine and numbers of turns of the engine we will receive the so-called characteristic of ignition. The characteristic of ignition Motronic is willingly shown because of the unusual form – she allows to draw a conclusion on exact influence of these parametres on a working condition of the engine.
- Certainly, there is a data exchange to injection. Including because at some gauges on the engine double appointment.
- At the disposal of the management block there are programs of updating of start of the engine, work of the cold engine, an operating conditions and so forth
- The management block submits such current what it requires at present on coils of ignition. In an extreme case (ignition is included, the engine does not work) at such ignition it cannot lead to coil damage even through long time.
- Detonation adjustment allows to maintain the engine with the greatest possible advancing of ignition that gives the best exit of capacity.
- Therefore engines capacity to 110 kw designed for operation on superfuel, at some loss of capacity can work also on standard gasoline since the management block distinguishes lower OCTANESое number and is switched to other characteristic of ignition.
- On the other hand, with the engine capacity of 128 kw reaches the best draught by application of gasoline super plus with OCTANESым number 98. In this case standard gasoline is provided only as the compelled decision at the extremely sparing style of movement.
- And, at last, the computer for preservation of the information on malfunctions in system of ignition which is read out in a workshop by means of the device for reading (the head Regular servicing) is still established.
