Technical data

15
All engines in the 2000 range are four stroke diesels
with direct injection and separate injection pumps for
each cylinder. In the 2000 range, the 2001 has a single
cylinder, the 2002 has twin cylinders, and the 2003 has
three cylinders. The 2003 is also available with
turbocharging, and then has the designation 2003T.
The engines are of modular construction, with many
common components, so in most cases they have the
same repair data and service methods.
The 2001, 2002 and 2003 are sea-water cooled as
standard. The 2002 and 2003 can be provided with
optional fresh water cooling. The turbo-charged engine
2003T also has fresh water cooling as standard.
The engines were built in an earlier A version and a
later B version. The main changes introduced on the B
versions were :
• Modified combustion chamber and 5-hole injector
nozzle with no sack hole.
• Changed injector opening pressure.
• New injection pumps (not 2003T) with increased
plunger diameter.
• Smoke limiter added to 2003T.
• Decompressor omitted from 2001 and 2003 (was
omitted during ongoing production of 2002A).
• Changed cooling system hose run (fresh water
system) on 2003T.
