In some area user need very simple generator set, they need only a single cylinder engine to drive a st or stc alternator by V-belt, this is very easy diesel generator set, and its easy maintained.

In other side, its electric output is not so stable as the one with Stamford alternator, also the power is smaller for lighting a home only.

Deutz engine, Cummins engine and also other chinese engine, can meet bigger power diesel generator’s requirement.
