Combustion engine development.

Improving efficiency with our fuel saving engine technologies

Stringent CO₂ regulations are pushing the combustion engine into an accelerated evolution phase. Never have changes been so dramatic as those we will see over the next decade.

One of these change is the introduction of Variable Compression Ratio (VCR) technology. Several car manufacturers have already announced to work on a production version of a VCR system and one presented its production engine to the public at the 2016 Paris Motor Show in September.

Who we are.

Over 20 years of experience

Gomecsys was founded in 1997. From the first hour, our goal has been to develop fuel saving engine technology. We started with the development of a new type of rotary engine. 

Our experience in engine design makes it possible to realize a custom VCR crankshaft design for any engine, from a 1 cylinder engine to a V8 within one month.
