This web is dedicated to HMG gas engines produced by German WJ POWER and operated by Czech authorised distributor HT EXTRA. Read About us to find out more.

Final goal of our web is to become state of the art on-line portal for customers offering complete technical, operating, maintenance and service data of all WJ POWER engines with possibility to even purchase complete engine, service kit or any spare part. Parallel to naked engines and parts we plan to offer you also engine equipment, beginning with own HUEGLI TECH following with MOTORTECH and HEINZMANN.
