Ignition Optimisation

IPI®-B – ignition with booster effect

IPI®-B offers an ignition method with booster effect operated by micro-controller. Ignition is optimised even under the harshest of conditions.

The method, patented by PRUFREX, increases the spark energy and extends the spark time, without affecting the secondary voltage. A special arrangement of the mechanical components, as well as the half-waves of alternating current, are used to give the usual ignition sparks higher energy and burn-time. As a result of this method, the conditions for a reliable ignition of the petrol-air mixture present in the combustion chamber are improved. In addition, emissions are also reduced, providing you with a more efficient and environmentally friendly product.
