Disengageable Clutch; Operation At Low Loads - Ingersoll Rand G330 Guía De Usuario Y Mantenimiento Manual

Disengageable clutch

The clutch is disengaged when the control lever is in position "N"
and engaged when the lever is in position "E".
IMPORTANT! The engine speed must not exceed 1000–1200
rpm during engagement and disengagement.

Operation at low loads

Avoid running the engine at idling speed or low loads for long
periods. This can cause increased oil consumption and oil leakage
from the exhaust manifold. (Oil passes the turbocharger seals and
is drawn into the intake manifold with the charge air when turbo-
charger pressure is low.)
This leads to soot deposits on valves, piston crowns, exhaust out-
lets and the exhaust turbine.
At low loads the temperature of combustion is so low that fuel is
not burnt up properly. This can lead to contamination of the lubric-
ating oil with fuel and eventually leakage from the exhaust mani-
fold.
In addition to normal inspections follow the points below to
avoid operating problems caused by running the engine at low
loads.
Operate the engine at low loads as little as possible. (If the en-
gine is tested without load each week, limit running time to ap-
proximately five minutes).
Operate the engine at full load for approximately four hours once
a year. This will burn off soot deposits in the engine and exhaust
system.
