Hazards of Low-Load Operation in Diesel Generators
Long-term low-load operation of diesel generators can cause incomplete combustion, carbon buildup, oil contamination, reduced efficiency, and accelerated wear, shortening equipment lifespan and increasing maintenance costs. This article explains the hazards, identifies typical signs such as blue exhaust smoke, turbo oil leakage, and power drop, and provides practical countermeasures, including regular high-load operation, proper sizing, high-quality oil and fuel, shortened maintenance cycles, and annual load testing, to ensure reliable, efficient, and stable generator performance.
