Keeping heavy-duty diesel engines powerful, efficient, and clean is one of the biggest challenges facing OEMs today. At Gomecsys, we’ve engineered a technology that will help to achieve these goals: Variable Compression Ratio (VCR) Technology, a breakthrough innovation for diesel powertrains.

Instead of redesigning your entire engine, our patented VCR crankshaft system gives you full and fast control over the compression ratio, ultra fast dynamic actuation of the compression ratio from 17:1 to 24:1 depending on conditions. The result? A more efficient, cleaner-burning engine, ready for the demands of heavy-duty transport, and flexible to run on different fuels.

→ Wide Range of Compression Ratio  (17:1 to 24:1) for optimal efficiency and power output
→ Instant Hydraulic VCR actuation for seamless transition during engine operation
→ No Additional Friction because the eccentrics are running at half the speed of the crankshaft
→ Drop-in Upgrade, works with your existing engine architecture
→ Alternative Fuel Ready, supports CNG and hydrogen combustion

𝗣𝗿𝗼𝘃𝗲𝗻 𝗕𝗲𝗻𝗲𝗳𝗶𝘁𝘀
Our technology has been proven in a variety of engines including diesel engines, delivering measurable reductions in fuel consumption and CO₂ emissions, without compromise on performance. All with ultra-fast actuation and zero additional friction.

𝗪𝗵𝘆 𝗜𝘁 𝗠𝗮𝘁𝘁𝗲𝗿𝘀
Regulations are tightening. Fuel prices are rising. VCR is a strategic enabler, helping manufacturers future-proof their engines, reduce total cost of ownership, and unlock increased efficiencies without starting from scratch.
