Road approval

Any form of performance enhancement must be type-tested and approved for road traffic. Compliance with pollutant and noise limits must be proven and confirmed by a declaration of conformity.

We at CombiFuel Swiss AG ( have chosen the recognized test center DTC (Dynamic Test Center AG in CH-2537 Vauffelin, for the preparation of the homologation documents. In addition, an individual homologation can be prepared on request. However, such an individual homologation may incur considerable additional costs (we will be happy to advise you in this regard upon request and if required).
