Circuit of electronic ignition UIS2
Electronic ignition
of new generation for 4÷8 cylinder motors, intelligent control of pre – ignition and energy. Detailed description of ignition can be found here.
Basic features
- Communication through RS-232 (diagnostics and adjustment by service program Manager), RS-485 (for cooperation for example with control system UniGEN) and further CAN
- Development of custom algorithms by function
- Configurable mapping of inputs and outputs
- Supplying voltage 24V+/-20%, supplying current 200mA/1,5A (quiescent / operative)
- Number of coils 1-8
- Output voltage 250-400V controllable
- Detection of detonations
- Detection of unburned ignition (measurement of quality of spark - over)
- Adjustable output energy, possibility to correct energies only in some cylinders
- Intelligent and very easy adjustment of output pre – ignition by stroboscope
- Correction of pre – ignition from rotation, during detonation, customable (for example according to the type of fuel mixture)
- Number of teeth for reading rotations 2-255 (both simple - sensor and double – sensor reading)
- 4x digital output
- 4x digital input
- 3x analog input - reset, crank (SW configurable, Hall sensor unit / Induction sensor / Kotlin), detonating sensor
- Supplying voltage for Hall sensor unit 5V,100mA
- Supplying voltage for sensor Kotlin 24V,100mA
- Test-mode
- Integrated tester (oscilloscope)
Connection

Process of signals
Ignition supports both double – sensor reading (gear ring turning on rotation of motor + "reset" thus reading of half - turn) and single – sensor reading (gear ring with "additional teeth", which is rotating on half - turn). From "reset" or additional teeth is winded the first cylinder burning, see picture:

Number of teeth in both variants is defined by parameter and is independent on cylinders count.
Easy adjustment of pre - ignition

Adjustment of pre – ignition by service program Manager is very easy. After activating mode of adjustment of pre - ignition TMCI2 burns with pre ignition 0° (in top dead centre). |

After connection of stroboscope it is sufficient to measure angle on first cylinder in mode of adjustment of pre - ignition (without fuel mixture, only for starter) and this value enter in service program. |

Than pre – ignition is adjusted (stroboscope indicates angle 0°). After mode of adjustment of pre – ignition will be TMCI2 burning with parameter defined pre - ignition. |
