At the request of DLW, Varanasi, a water temperatureprofile of
the EMD 16-cylinder engine was developed ontest bed number one
using PT 100 ResistanceTemperature Detector (RTD) and advised to
DLW,Varanasi.
Microprocessor based control system and micro-controller based
engine governing system have beenintroduced in ALCO 16-cylinder
engines. For theoptimisation of engine operating line by MP
directorate,
fuel maps for 3300 hp and 3600 hp were developed toestablish the
optimal engine operating points (speed,B ME P, a nd h p) . T he r
el ev an t r ep or t N o.TR/ED/2010/208 was issued.
The testing of power assembly components supplied byM/s GETS,
USA for the EMD 16-cylinder engine wasundertaken to establish
alternate sources of supply oft he se c om po ne nt s. T he r el ev
an t r ep or t N o.TR/ED/2010/210 was issued in September 2010.
In accordance with minutes of DMG, to curb failures ofgaskets in
plate type lube oil coolers, two makes ofcompact brazed type lube
oil coolers were tested andreports released for further field
testing. The relevant
report No. TR/ED/2010/211 was issued in December2010.
A new design of single entry (modified) exhaustmanifold for M/s
ABBs turbo-charger TPR-61 wastested and Report No. TR/ED/2010/211
released. This
new design of the manifold is expected to improve

The ALCO 16-cylinder engine of test bed number twowas altered
with necessary arrangements for fitting theElectronic Fuel
Injection (EFI) system. The optimisationtests forthe EFIsystem were
carried out and finallyfittedon the first EFI locomotive, which is
under operationalobservation.
The obsolete test bed control system for the 12-cylinderand
6-cylinder ALCO engine test beds are underreplacement with modern
test facilities. These areexpected to complete in ensuingyears.
RDSO has undertaken three new infrastructureenhancement works
for improved testing facilities,namely: upgradation of dynamometer
of ALCO 16-cylinder test bed for catering to higher horse power
needs, augmentation of heat disposal arrangements forall test
beds, and enhancement to air-compressor andair-starting motors to
cater to the new higher horsepower test beds.
Officers and supervisors of Engine Development and
Motive Power Directorate attended several workshopsat IIT,
Kanpur during the year to update the knowledgeand skills for
research in engines. The topics coveredincluded Advances in
Combustion and Transportation,Diesel Particulate and NOx
Emissions,
After intense literature review, specifications for state ofthe
art emission testing and measuring equipment wereprepared for
procurement and fitting on the EmissionTest Car (ETC) for IR. The
ETC is expected to becomefunctional in ensuing financial year
2011-12.
An EOI was floated in March 2011 and discussions wereheld with
several vendors for preparation of thetechnical specifications.
This project shall enablestepwise improvements in emission
performance ofboth, the ALCO 16-cylinder 3100/3300/3600 hp andEMD
16-cylinder 4000/45000 hp engines.
An EOI for the development of CRDI for ALCO 16-cylinder engine
was released in Nov, 2011. The detailedtechnical specifications
have been prepared andapproved. The tender is expected to finalise
in thecoming year.
This project was primarily undertaken to benefit from
theavailable supplies of CNG/LNG in India, reducedependence on
imported diesel, and further reduce theemissions from ALCO engines.
The preliminaryspecifications were prepared and EOI floated.
Theprojectis likely to be completed in the year 2012-13.
