Our company.

Experienced high-tech specialists, driven to make the difference

Gomecsys was founded in 1997. From day one, our main target was to develop a technology that would make existing engines more efficient and economical. Why? Because average engine efficiency is really poor and there is so much to gain.

While a peak efficiency of 40% for today’s gasoline engines is very impressive, the average efficiency is only about 25%, meaning that about 75% of the fuel energy is lost as heat and not helping to propel the car. Hybrid and full-electric vehicles may produce less CO2 once they are used, but while building those types of cars, there are higher level emissions generated.

There’s another way though. And it’s called Variable Compression Ratio (VCR): a crankshaft design that can be customized for any engine, big or small, quite easily. With Variable Compression Ratio the engine can run at its optimum compression ratio at any load improving its average efficiency closer to its max efficiency. It took 20 years of developing to optimize our patented, fuel saving technology.

Despite the electrical alternatives car manufacturers already offer, we truly believe that the combustion engine still has a long future ahead of us. Because efficiency is what the world really needs. And we are proud to offer a sound solution.

Our history
1997 Gomecsys was founded. We started with the development of a new type of rotary engine.
1998 Start of the development of the first generation VCR technology. The ongoing development of our patented VCR technology became our main target. First focus was the development of a 2 cylinder engine.
2000 The first 2 cylinder VCR protoype gave us the proof of principle.
2003 We chose Prodrive Europe, a leading automotive engineering company, as our technical partner in the development of the first generation VCR technology.
2005 We succeeded in getting EUREKA funding from the Dutch government to develop a 4-inline demonstrator VCR engine in cooperation with Prodrive.
2007 The second generation of our VCR technology was developed in another 4-inline engine.
2008 The 4-inline engine was upgraded with some important changes to the 2B generation.
2010 For the third generation we developed an all-new 2-inline engine with some major upgrades.
2012 Collaboration with PSA Groupe and development of our 4th generation prototypes. The main change was the elimination of the actuation ring gear at the front of the engine.
2014 Implementation of split eccentrics i.c.w. a one piece crankshaft which resulted in the 5th generation.
