Chinese Diesel Generator - Try #1

Here, the engine is running a 5 kW generator by spinning it at 3600 rpm. With a 4 inch pulley on the engine and a 3.1 inch pulley on the generator, the engine speed is about 2800 rpm, its maximum rated speed. The engine is not too happy at this speed although it makes acceptable line voltage. I wouldn't want to run this setup without standing over it ready to shut it down at any time. Note the distance of the belts from center-to-center.
