In comparison to gasoline powered generators, the diesel generators produce higher engine noises. Diesel generators tend to weigh more than gasoline units and will therefore need more planning on where to set up, as well as how to load and unload the heavy unit. Some localities have prohibited the operation of diesel engines over a prescribed period of time, for purposes of reducing pollution. There may be an increase in the costs of diesel generators due to some requirements by some localities regarding double-wall containment on the on-board fuel tanks. Incidences of wet stacking may occur in a diesel generator due to light loads, which may result in a smoking engine that also runs rough. Source: aboutgenerator.com
