The Big Particles in the Oil
The oil particle count large counts the coarse particles in the oil: the debris that indicates serious damage – flakes from gears, fragments from bearings. CHIPL appears in maintenance documentation as an alarm criterion.
Why the Size Matters
Fine particles are normal: every engine produces minimal abrasion. Coarse particles are the alarm: they mean that something is breaking inside. The count of large particles separates the normal background from the serious warning.
CHIPL appears in this meaning mainly in engine monitoring documentation. Together with the exceedances CHIPE and the total count CHIPT, it forms the family of oil monitoring values – the laboratory of the lubricant.
