Universal Ignition

---

The ignition is developement for the two or four-cycle automobile and motocycle engines. The ignition allow the programmable advance curve and intensity of the excitation two coils. All the functions and optional working ignition regimes can be set by a personal computer. For this reason there is a Ignition Control application that also enables online visual control of real values of turns, pre-ignition (set-up time). To connect the personal computer through ignition the standard extension cable of RS232 link should be used.

The pre-ignition directing is realized by the ignition microprocessor that sets the delay time of ignition (the ignition advance) according to the set curve and actual turns.

Using the extension function input Ex it possible change over the ignition curves. The pre-ignition directing is realized by the conversion of asked pre-ignition curve into schedule of time delays. Depending on actual turns of a motor the individual time delays are chosen from the schedule and via the microprocessor exactly measured and that is how the final effect of set up directing works.

The application Ignition Control newly provides the function of pre-ignition debugging by acceleration brake where the acceleration of motor is watched when repressing its own mass. The acceleration of motor turns is adequate to the twisting moment, which is a ondition.

The advance set up

The last and the most important point in the installation are the proper settings of the ignition to serve all demanded functions perfectly.
First it is necessary to know what maximal pre-ignition advance each engine demands in the first period. This maximal pre-ignition advance must be set in the reading sensor of rotation (e.g. 35°) and also be held as a reference value in the program in a Pre-ignition curve bookmark, item Rotation Reading Sensor. Always the value of pre-ignition set in the sensor must be adequate to the value set in the program. According to this value the conversion of the ignition advance curve is saved in a schedule, mainly the actual truth of On-line visualisation. The value of advance on the rotation reading sensor can be corrected later by comparing the actual value of ignition found out e.g. by a stroboscope to the value of advance set in On-line visualisation.

The pre-ignition directing is realized by the ignition microprocessor that sets the delay time of ignition (the ignition advance) according to the set curve and actual turns.

For easier set up the ignition advance is determined in [mm] in motorbike engines. That is why this program enables the automatic ignition conversion from [mm] to [°]. The ignition conversion window is activated by double click of the mouse in bookmarks Ignition curve and items Rotation reading sensor.

Signal indicator

The profile of all functions is saved in the ignition memory that keeps data even without power supply. The memory content is recorded from the Ignition Control program.

If the memory has never been recorded or the interruption of the last recording happened this state will be signalized by a short red flashing after switch-on. All set ups will then be given by a producer. The right memory content is indicated by a constant green light. The recording data from the computer is indicated by a red constant light. If the ignition changes into the protective mode (the engine is not running and the regime is allowed) the green indicator stops lightning (the inductors are not being excited). After getting the impulse from the rotation reading sensor the green indicator will switch on again (re-excitation).

Ignition Control application

The electronic ignition consists of many functions and their set-up can be realized through a personal computer with Ignition Control program. The computer communicates through the RS232 interface of speed 19200Bd. That is why the computer must have at least one COM port and/or USB/RS232 transducer. The application works under the Windows 95 or higher. It requires 4MB of empty space in hard disc. The minimum PC configuration is Pentium 166MHz, 32MB RAM is accurate.

Ignition Control Program is divided into four individual parts:

• Online visualisation
• Ignition advance curve
• Extended functions

Online visualisation showing this parameters

• Engine RPM and Advance
• Ignition advance

To run visualization it is always necessary to connect the computer with the ignition by a serial extended cable, to open the communication port and to run the visualization by pressing the button Start. In case that after pressing the button Start the real data do not display please control the connection of communication cable, the number of the used communication port and the voltage of the ignition.

The ignition advance curve

The basic character of the ignition is the directing the ignition advance according to real turns of the engine. To set ignition advance directing characteristics there is Ignition advance curve bookmark.

Flash energy

To optimize the type of the inductors and its excitation there is Flash energy button. It is necessary to set medium or minimum excitation that will protect the inductors against the over excitation and their over heating when using inductors with resistance lower than 4ohm (min 2,5 ohm). If using the inductors with the resistance higher than 4ohm there is medium or maximal excitation settings. The settings of Flash energy directing that directs exciting according to values of board voltage is the compromise of the excitation inductors.

Board voltage	Control flash energy
> 9V	Maximum
9V - 11,5V	Medium
< 11,5V / < 3300RPM	Minimum
< 11,5V / 3300 - 6500RPM	Medium
< 11,5V / > 6500RPM	Maximum

It possible configuration coil current by exciting curve or table. You can set exciting from 20 to 95% per a round.

Pre-defined process of coil exciting

Acceleration brake

There is a new function in Online visualization. It is Acceleration brake that realizes fast 5 second engine record with the calculation of the turn derivation (acceleration). It proportionately responds to torsional moment.

Measure process

• Check the Engine Turn Limits settings before use
• Leave the engine run idly and get ready for its acceleration
• Press Start button
• Wait exactly 1 second to run the record
• Running of the record for 5 seconds
• End up the record and read the measured values of turns from ignition
• Display and conversion the measured values to the graph

Why you must use the Universal Ignition

The electronics ignition allows very exactly direction of advance. This provide more of engine power in wide rande RPM. The ignition allows very easy engine to start (optimal advance), more power (high energy of flash) and with the rules of economy driving then decrease of fuel consume. The ignition is work in guaranteed voltage range from 3,5V to 25V.
