Circuit of electronic ignition UIS2 (TMCI2,GEIS)

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  functions
• 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)

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:
