TECHNICAL DESCRIPTION
MD 11 C and MD 1 7C, are 2 respectively 3 cylinder, 4 stroke marine diesel engines,
with direct injection and sea water cooling.
ENGINE ASSEMBLY
The crank case, cylinders and cylinder heads are made of cast iron. The engines
have replaceable cylinder liners and overhead valves.
LUBRICATION SYSTEM
The lubrication system has a full-flow oil filter which cleans the oil before it reaches
the lubrication points. The oil pump has a relief valve which prevents the oil pressure
from becoming excessive.
ELECTRICAL SYSTEM
The engine has a starter motor and an alternator with a built-in rectifier. Voltage
regulation is done by a transistorized regulator mounted on the alternator. The
alternator can charge two batteries, independent of other, if a charging distributor
(accessory) is fitted to the alternator. A main fuse, which can easily be reconnected,
is fixed to the engine. It protects the electrical system from damage in the event of
overloading. The wiring diagrams for the engine and instrument panel are shown on
page 29.
