1.1. DESCRIPTION 0 F ENGINE
The ESL 12and 16 cylinder Mark2engineshavebeen designed togivea high fuelefficiency
and a long service life with the lowest possible maintenance and operating costs.
Turbochargers,intercoolerandfour-valve cylinderheadsarefittedasstandardtoincrease
the fueleconomy and the available power. Theengine can besupplied in either distillate
fuel (refined diesel oil) burning
or heavy fuel (unrefined oil) burning versions.
The crankshaftkonnecting rod assembly is mass-balanced to minimise vibration and
torsionalstresses. Therotatingmassesof theengineanddriven equipmentare’tuned’byan
individually selected flywheel and a damper for the same reason and to avoid harmful
resonant stresses over the engine’s speed range.
A flat drive belt transmits power from the crankshaft to the engine driven pumps.
A two stage, automatic engine protection system, normally consisting of an alarm circuit
and an engine shutdown circuit operating via the governor, is triggered
if sensors detect
operatingconditionsoutsidesafelimits, e.g. lowlubricatingoilpressure. Engineoverspeed
protection
is provided by an independent, mechanically operated system, which shuts off
the engine’s charge air supplywhen operated.

Also,
if using a geared adaptor, the appropriate (reduced) torque MUST be used, to give the
correct torque
on the nutbolt itself. Failure to do this can result in serious component
over- stressing.
