The way to world leading efficiency
for Truck engines

Trucks

In 2024, Gomecsys reached a significant milestone in engine innovation by introducing an upgraded gear mechanism for its Variable Compression Ratio (VCR) system. This enhancement dramatically increases the system’s strength and durability, enabling it to meet the demanding requirements of truck and off-highway diesel engines. With this breakthrough, Gomecsys is poised to revolutionize these industries, offering tailored solutions that enhance efficiency, reduce emissions, and maintain exceptional performance under the most challenging conditions.

THE GOMECSYS VCR SYSTEM KEY BENEFITS

Key Benefits for Truck
and Off-Highway Diesel Engines

Gomecsys VCR technology delivers a range of transformative benefits for trucks and off-highway vehicles, addressing both performance and sustainability requirements.

Precision Compression Ratio Control

The Gomecsys VCR system provides unmatched flexibility by varying the Top Dead Center (TDC) position up to 6 mm, allowing for a wide compression ratio (CR) range:

  • Diesel Engines: A CR range of 25:1 to 16:1 optimizes fuel efficiency during part-load conditions while maximizing power output under full load. This dynamic adjustment (within 0.2 sec) ensures that engines perform optimally across all operating scenarios.
  • Pure Hydrogen Engines: For hydrogen applications, a CR range of 16:1 to 10:1 reduces knock sensitivity at full load while maintaining peak efficiency during part-load operation. This makes the VCR system a highly adaptable solution for next-generation heavy duty engines.

Dual-Fuel Flexibility

Gomecsys VCR technology is at the forefront of dual-fuel innovation, enabling seamless transitions between hydrogen and diesel operation, reducing CO₂ emissions by 80%.

  • Hydrogen at Part Load: The system allows trucks to run on 100% hydrogen at a compression ratio between 16:1 and 12:1 during part-load conditions, with zero CO₂ emissions.
  • Diesel at Full Load: During high-load demands, the engine switches to 100% diesel operation at a compression ratio of 17:1, ensuring robust power delivery and reliability.
  • Retaining Existing Turbocharger Setups: The Gomecsys Dual-Fuel H2D VCR system integrates with existing turbocharger architectures, eliminating the need for costly modifications. This compatibility simplifies adoption for OEMs, enabling them to enhance engine efficiency without redesigning entire systems.
  • Operational Flexibility: For regions lacking hydrogen refueling infrastructure, trucks equipped with the VCR system can operate entirely on diesel, providing a practical solution for global operations and long-haul applications.

High Efficiency Across Load Conditions

The ability to dynamically adjust compression ratios ensures maximum efficiency and performance across varying load conditions. Whether operating under low-load scenarios or handling heavy-duty demands, the Gomecsys VCR system optimizes combustion to deliver the best possible fuel economy and power output.

Sustainability Without Compromise

Meeting stringent environmental regulations is a critical challenge for the trucking and off-highway industries. The Gomecsys VCR system enables fleets to significantly reduce CO emissions without sacrificing power output.

SUSTAINABLE FUTURE
