Marine diesel engines. Operator’s manual
-
It is not a good practice to measure the compression pressure on only few cylinders and
presume the compression on the remaining cylinders.
-
Compression pressure varies with genset speed. Check genset speed when measuring the
compression pressure.
-
The compression pressure will be slightly higher in a new or overhauled genset due to new
piston rings, valve seats, etc.
-
The compression measurement is advised only as a comparison measure between all
cylinders of the same engine. If differences greater than 15% are verified, it is advisable to
look for the cause, disassembling the affected cylinder unit.
