Polini develops it specifically for competition builds where control of the ignition advance is a real part of engine tuning.\u003c\/p\u003e\n\u003cp\u003eIn a tuned 2-Stroke engine, the ignition not only has to produce a powerful spark: it has to do so at the \u003cstrong\u003eexact moment relative to the position of the piston\u003c\/strong\u003e. Too much advance can increase temperature and the risk of detonation, while insufficient advance can cause the engine to lose response and fail to make proper use of combustion.\u003c\/p\u003e\n\u003cp\u003eThis system uses a \u003cstrong\u003elow-inertia internal rotor\u003c\/strong\u003e, reducing the mass rotating together with the crankshaft. With less rotational mass, the engine can \u003cstrong\u003egain and drop RPM more quickly\u003c\/strong\u003e, something especially beneficial in racing setups that operate at high revs.\u003c\/p\u003e\n\u003cp\u003eThe main difference compared to a conventional ignition lies in the \u003cstrong\u003eprogrammable digital management of the advance curve\u003c\/strong\u003e. This makes it possible to adapt the ignition timing according to the RPM and the engine's specific configuration, instead of working with a fixed curve intended for a generic build.\u003c\/p\u003e\n\u003cp\u003eIn an engine with a cylinder, a high-displacement exhaust, a high compression ratio, or very aggressive port timing, being able to adjust the curve makes it possible to achieve an engine that \u003cstrong\u003eresponds strongly when it comes on the pipe and maintains controlled combustion at high RPM\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eProgramming is carried out using the specific Polini system for PVL stators. The \u003cstrong\u003ePolini programmer ref. 171.0686\u003c\/strong\u003e allows the advance curve to be modified according to the builder's needs and is sold separately.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does it contribute to a racing build?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLower crankshaft inertia:\u003c\/strong\u003e the internal rotor promotes faster revving.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfigurable advance curve:\u003c\/strong\u003e allows the ignition to be adapted to the cylinder, exhaust, compression, and operating range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDigital management:\u003c\/strong\u003e greater control of spark timing throughout the RPM range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMore precise tuning:\u003c\/strong\u003e especially useful in engines that operate outside the original parameters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRacing application:\u003c\/strong\u003e designed for competition engines and high-level builds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Polini.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 171.0580.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTechnology:\u003c\/strong\u003e PVL.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e digital racing ignition.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor:\u003c\/strong\u003e internal, low inertia.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvance curve:\u003c\/strong\u003e programmable.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Polini PRE \/ racing crankcase.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible programmer:\u003c\/strong\u003e Polini 171.0686.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e competition.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible models\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePIAGGIO\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eZip 50 SP 2-Stroke LC 1996-2000\u003c\/li\u003e\n\u003cli\u003eZip 50 SP 2-Stroke LC \u0026gt;2001\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eYAMAHA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eJog 50 RR LC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Polini Motori s.p.a.","offers":[{"title":"Default Title","offer_id":67881289089415,"sku":"171.0580","price":434.63,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0860\/6223\/5959\/files\/171.0580.webp?v=1793790309","url":"https:\/\/motoscoot.net\/en\/products\/ignition-racing-digital-polini-pvl-programmable-pre-crankcase","provider":"Motoscoot","version":"1.0","type":"link"}
