Karakteristike "A" i "D" su samo primjeri mogućnosti zadavanja kuta predpaljenja. Tražena karakteristika može imati diskontinuitete (tj. novi kut paljenja ne mora biti u relaciji sa predhodnom). Moguće je simulirati rad centrifugalnog regulatora, ali i napraviti korekcije u toku kuta predpaljenja (kakve su nemoguće sa centrifugalnim regulatorom). Npr. Limitiranje broja okretaja lako i jednostavno se izvodi naglim rezanjem kuta predpaljenja na nulu.</div> <bR> <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-2650537455752702" crossorigin="anonymous"></script>  <ins class="adsbygoogle" style="display:block" data-ad-client="ca-pub-2650537455752702" data-ad-slot="7117608876" data-ad-format="auto" data-full-width-responsive="true"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script> <bR> <div> <IMG SRC="5b75eb50.jpg" border=0 width="350" height="181" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> izgled pločice paljenja - dimenzije sa plastičnom kutijom: 123*70*29mm</div> <bR> <bR> <div> <IMG SRC="5b85e160.jpg" border=0 width="350" height="278" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> oscilogram jednog kanala baznog napona drivera bobine kod simulacije 10.000 okretaja u sekundi</div> </td> </tr></table></body>
