The crystallization of cutting-edge technology
Based on his rich experience and continuous improvement, Yanbach has developed the 6 series of 1.8 to 4.5 MW reliable internal combustion engine products. Its 1,500 RPM speed increases power generation density and reduces installation costs. The 6 series internal combustion engine is equipped with a precombustion chamber to maximize gas combustion efficiency, while reducing emissions. The proven design and optimized components enable the equipment to operate for 60,000 trouble-free hours prior to overhaul. The all-new J624 is equipped with two-stage turbocharging technology to provide greater efficiency and flexibility in response to changing environments.
Technical characteristics
