A generator unit is governed to hold set speed and carries its own rating, so it is not a drop-in replacement for a machine engine even though the block is the same.
The same engine is published at 41.4 kW continuous and 50.1 kW standby for generator duty, against 52.1 and up to 64.1 kW at 2500 rpm.
Another make's four-cylinder engine displaces 3.331 L against 3.319 L here, so capacity alone does not identify the engine.
Generator builds are described as mechanical, while several market listings offer the same designation as electronically controlled, pointing to other suffixes in the family.
Units for this family appear from 1080 to 4500 per piece, most between 2000 and 4000, alongside entries priced per parcel, per dozen and per kilogram.
