OK-N engine debuts in first test at Franciacorta

After the recent World Motor Sport Council, in addition to the 2023 calendar, the Federation has formalized and presented a project targeting national competitions. In fact, the new OK-N engine will take advantage of the new homologation cycle starting in August 2022 to be introduced in national markets.

The new powerplant, based on the OK model, has been designed with a national perspective, with the intention of containing costs and encouraging the approach of drivers from the national “nursery” or feeder series into international categories thanks to an OK-N World Championship with entry through qualification (a sort of Grand Final). 

Late yesterday afternoon at the Franciacorta Karting Track, the OK-N engine entered the track for the first time in the Tm Racing, Modena Engines, Vortex and Iame versions. Lots of feedback from drivers like Lorenzo Travisanutto in close talks with engine designers and FIA managers, grappling with the first test session. 

The engine defined as a "hybrid" between an OK and OKJ impressed those present not only for its good performance but especially for its potential in view of the market and the national categories for which it was designed.



The main differences? The slightly heavier weight (minimum weight 153/154 kg kart and driver), the valve with the power delivery lower than the OK (15,000 engine rpm), the carburetor with a choice that for now seems to fall on the diaphragm one rather than the tank, again with a view to keeping costs down. Difference also in what concerns the exhaust manifold (internally). 

This preview will be followed by an in-depth discussion with the protagonists of the test after the close of the OK/OKJ European Championship.
