Possible replacement MASTER 4TCI. 

 

The unit MASTER ignition has been functionally designed in order to control advance or injection of combustion engines ranging from one to six cylinders, with whatever configuration of scanned teeth, types of sensors and features like 5D maps of advance and injection control, integrated pressure sensor, temperature, tachometer output, strobe lamp, charging control, engine speed and turbo preassure PID regulation, control switching on of fuel pump. Unit MINI contains only 3 TCI outputs.

The list of features mentioned above determines MASTER ignition to be used either for a service or tunning replacement of conventional motorcycle or automobile ECU units, usable for ignition or injection coil control. The integrated redundancy of sensing, together with other key features makes Master ignition very suitable for marine and aviation applications, moreover, thanks to the wide range of operating revolutions can be also used for turbines.

The function of MASTER ignition relies on FPGA technology, which provides digital-analog conversion of sensor signal, as well as its evaluation and calculation of the mathematical model of the real rotation. Simultaneously, it deals with other operations i.e. redundancy sensing, total control of CDI converter, advanced features and signal records. FPGA technology is interesting not only for its high operating performance but particularly for its accuracy, which in principle microprocessor-based systems cannot achieve.

Preview of application

Online visualisation

This is an operational display of function and status of ignition unit MASTER. In order to have functional display it is necessary to have USB connection and switch power supply on.

Visualised data

• Speed (rpm) and advance of engine [°]
• Sensor voltage PA, PB [V]
• Power supply [V] and Temperature [°]
• Converter CDI – Voltage [V], pulsed current [A] and load [%]
• Signals 1OA - 1OH, DI1, DI2, DO1, DO2, AI1, AI2, PA, PB
• Engine hours [s]

Maps of advance

Maps provide a fast tool to display and model individual curves in advance [1] – [8] in full angle range ±360°. The given figure influences the moment of output switch from 1OA to 1OH. By using digital (DI1, DI2) or analogue outputs AI1, AI2, PA, PB) it is possible to operationally switch among the maps.

Modelling tools:

• Editor maps in advance – quick draw of maps according to specified points
• Mouse modelling – direct editing of maps is possible by mouse movement
• Map shifting – whole map shifting or selected parts only
• Copying – copies of maps one to another of your choice
• Table – direct entry of specific points into table
• Filter – in-progress filtration, rounding the edges of maps

Sensing configuration

Configuring the sensing of engine rotation is the key part of ignition unit MASTER ignition. Within its setting it is possible to select Pick Up voltage sensing level and adapt this level for more range of engine speed. There are other settings to be selected such as filter setting, angles of Trigger Wheel teeth maps or alternatively second level of voltage for synchronisation.

Pick Up voltage sensing level and Trigger Wheel teeth map are predefined for many application Eg. BOSCH 60-2, BOSCH 36-2, BOSCH 2+1, BMW 36-1, FORD 36-1, SUZUKI 24-2, YAMAHA 16-2, HARLEY 32-2.

Oscilloscopic record

Oscilloscopic record is used in order to graphically visualise measured and calculated data. This helps to quickly evaluate the proper and accurate function of ignition unit MASTER. It can thus evaluate the correctness of voltage sensing, counting teeth of mathematic model of the real rotation and angels of closing of output coils.

An example to be given; curve angle of engine displacement must be regularly and horizontally increased from 0 to 360°. If there is any change of steepness in the curve or the angle is shorten, the problem is to be found either in wrong angle set up, number of teeth, the type of synchronisation or unsuitable voltage for sensing.

Visualised data:

• Rotation sensor voltage, PA, PB [V]
• Tooth index of sensed blade, Tooth index A-B [-]
• Engine displacement angle, Angle A-B [°]
• Engine revolutions, Revolutions A-B [%]
• Outputs closing 1OA-1OH [-]
