MaK M 20 C<br />
Enhanced M 20 series offering many<br />
advantages for the operator<br />
In line with its philosophy of ensuring<br />
that all its engines remain stateof-the-art,<br />
<strong>Caterpillar</strong> has refined<br />
its M 20 engine series, which has been<br />
successfully established in the market<br />
for 14 years, and will now distribute it<br />
under the type designation M 20 C.<br />
<strong>Caterpillar</strong> started its new advanced<br />
MaK long-stroke engine programme<br />
with the market launch of the M 20<br />
in 1992. With the three series M 32<br />
(1994), M 25 (1996) and M 43 (1998)<br />
subsequently introduced every two<br />
years, MaK diesel engines now cover<br />
an output range of 1,020-16,000 kW.<br />
In common with all types of the<br />
MaK long-stroke engine generation,<br />
the units of the M 20 series are optimised<br />
to meet the special requirements<br />
of ship operation and are highly<br />
reliable and cost-efficient. With their<br />
long-stroke design concept and the<br />
concentration on fewer components<br />
with high function integration, they<br />
have proved optimal for installation as<br />
both main propulsion unit and marine<br />
auxiliary genset in a very wide range<br />
of vessels.<br />
As a typical representative of the<br />
highly developed MaK long-stroke<br />
engine family, the M 20 meets the current<br />
IMO guidelines; NOx emissions<br />
with fixed engine timing and without<br />
exhaust gas aftertreatment are definitely<br />
below the defined limit value.<br />
An optimal combustion process is<br />
achieved with the combination of<br />
moderate speed, high injection pressure,<br />
high compression and precisely<br />
adjusted turbocharging. This results in<br />
low specific fuel consumption, heavy<br />
fuel suitability and low emissions –<br />
characteristics that guarantee high<br />
acceptance in the market.<br />
High cost-efficiency is achieved by<br />
the interaction of low fuel and lube<br />
oil consumption and long component<br />
service life. The maintenance intervals<br />
are 15,000 hours. High reliability<br />
in both MDO and heavy fuel operation<br />
is thus guaranteed.<br />
The engines of the M 20 C series are<br />
supplied as in-line engines in a 6-, 8-<br />
