Genset diesel generator set use a compression ignition method (no spark plug needed). This makes their power output more stable. They can handle short-term overload operation.The generator sets have special designs. For example, they have rainproof and dustproof enclosures, low-temperature preheating systems, and upgraded air filters.With these designs of gensets, they can operate stably in dusty environments like deserts, extremely cold areas, and outdoor rainy seasons.
