The GDD-300GFK diesel generator set combines advanced Yuchai engine technologies with a highly efficient EvoTec alternator system. Reinforced heat-resistant materials enhance the reliability of key components (cylinder block and crankshaft), while patented technologies (point-and-linear engagement of the rear gear chamber and a 4-valve system) ensure low emissions and quiet operation. Special cylinder liner sealing technology reduces lubricating oil consumption, and standardized components minimize maintenance costs. An intelligent control system with triple explosion protection (knock sensors and crankcase/intake manifold explosion-proof valves) ensures safety. The EvoTec alternator, with AVR parallel operation stabilization technology, demonstrates excellent dynamic response under any load, a waveform distortion factor below 0.8%, and effective heat control, making it an ideal eco-friendly solution for a variety of power generation applications.
