ERIE, Pa. - General Electric and CBRail have
signed a purchase contract for the rebuilding
of 20 M62/ST44 locomotives in Poland, with an
option for a additional 10. The M62/ST44 has
been a workhorse of the Polish fleet over the
years, but requires a rebuilding program to
improve reliability and reduce operating
costs.
[eng]ST44 is the Polish name for a Soviet heavy
freight diesel exported to Poland beginning in
the 1960s and known in the USSR under the
designation M62. Deliveries continued until
the 1980s with 1,113 locomotives delivered in
total.
CBRail has contracted with GE for each
locomotive to be fitted with a new GE power
unit containing a FDL12 engine, alternator,
and auxiliary equipment. Traction motors will
also be upgraded.

jeśli są to takie same silniki jak w GE U23B to mają mniej więcej
tyle lat co M62
U23B produkowane były w latach 1968-77
silnik GE 7FDL12: 2250KM (wg innych danych 2250-2750KM), 12 cylindrowy
maks. 1050obr/min
min 550 obr/min

Emission certification UIC 2
To ja podam przykładowe wyniki ST44-R007 ze starym silnikiem 14D40
zmierzone w ZNTK Poznań wg. cyklu F dla normy PN-EN ISO 8178-1 w 2004 roku:
CO =3,8 g/kWh; HC=1,7 g/kWh; NOx=16,5 g/kWh (podsumowując zmieściła się
w normach ORE B13 obowiązujących od 01-01-1981 d0 01-02-1991)
Dla porównania BR232 z silnikiem 5D49 zbadana w Pesie w 2004:
CO=3,4; HC=1,75; NOx=17,42
A tu jeszcze jeden "Gagarin" M62-1241 z silnikiem 14D40 zbadana w ZNTK
"Kuźnica Wareżyńska" w Dąbrowie w 2005 roku:
CO=4,93; HC=1,97; NOx=14,19
I dla porównania BR231 z silnikiem 5D49 zbadana w 2006 r. w ZNTK Poznań:
CO=3,16; HC=1,3; NOx=15,8
Pozdrawiam
