TECHNICAL DESCRIPTION
The MD5A is a single-cylinder, 4-stroke, marine diesel engine with direct injection and
sea-water cooling.
ENGINE ASSEMBLY
The engine block and cylinder head are made of cast iron. Cylinder angle 45o. The
cylinder liner is replaceable. The engine has overhead valves.
LUBRICATING SYSTEM
The lubricating system includes a full-flow oil filter which filters all the oil before it reaches
the lubricating points. A relief valve in the oil pump prevents the oil pressure from
becoming excessive.
ELECTRICAL SYSTEM
The engine has a starter motor and alternator with built-in rectifier. Voltage regulation is
taken care of by a transistorized regulator mounted on the alternator. The alternator
makes it possible to charge two battery circuits independent of each other if a charging
distributor (accessory) is fitted on the alternator.
A main fuse, which can easily be re-connected, 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 27.
