Development of Electronic Fuel Injection for ALCO Locomotives of Indian Railways

Electronic Fuel Injection fitted locomotive 16502R has been launched in commercial service by Shri V. Ramachandran,Director General /RDSOon 14 Sep 2011 at Alambagh Diesel Shed, Lucknow. A short training course has been organized for the diesel maintenance and running staff of Lucknow Division. A test scheme has been issued to the Diesel Shed for monitoring the performance of the EFI fitted locomotive. Performance of the locomotive is being monitored by RDSO.

Looking back, EFI was developed by RDSO in a structured way and as part of a well thought out plan. Initially, detailed literature survey was done and technical specification developed for procurement of one set of Electronic Fuel Injection System. Global tender was floated for purchase of 16 nos. of electronic Fuel Injection Pumps, Engine Control Unit, various Sensors, all wires and harnesses.In absence of controls lab in RDSO, a special team was created to look after the various aspects of EFI development. This included in-house CAD development of fuel headers, pipes, connections, layout of wire harnesses, optimization of the injection characteristics of the electronic FIP, development of a new injector after detailed computational fluid dynamics simulation (done in-house), modification of components to fit the sensors etc. ECU calibration was a new activity and required development of design of experiments and mapping of the various parameters. About 6 months time was taken for ECU calibration. Interfacing of the ECU to the Test Bed controller and the Locomotive traction control system was the most critical of the activities and an MOU was signed with IIT Kanpur to develop the necessary hardware and software for

these interfacings. The EFI system was first tested extensively on the Engine Test Bed in the ED Dte. for debugging. This was then followed by a 'dry run' at the Alambagh Diesel Shed on a diesel locomotive including a load box test. The final fitment was done at DMW Patiala. A number of iterations were followed at each step.

With the introduction of ECU, a 4% reduction of fuel consumption over duty cycle has been achieved with high

p r e s s u r e injectors. In addition there is complete elimination of black smoke in exhaust during steady-state and transient operations. Fitment of EFI is expected to eliminate hot engine

Mumbai-Ahmedabad routes during the current financial year. In order to facilitate smooth introduction of train services, RDSO has communicated to all the concerned Railways for removal of infringements on the proposed routes to ensure that the delays that took place on ER do not recur. Further, RDSO has obtained dispensation from conduct of oscillation trials from CCRS. CCRS has granted the necessary dispensation with the proviso that route proving run will be required to be conducted by RDSO on the proposed routes.

EFI locomotive shall be subjected to three months field

trial followed by finalization of detailed EFI kit specifications and drawings. The change notice shall then be released to DLW and DMW for series fitment of EFI on the ALCO locomotives.

Introduction of AC Double Decker (3135 mm wide) Train Services

After series of validation trials and clarifications furnished to CCRS and Board, Board vide letter 2011/CEDO/SR/21 dated 26.09.2011 have permitted the operation of 1st series of double decker coaches (3135 mm width) for commercial operation on Howrah-Dhanbad section of Eastern Railway. Commercial services have since started from 01.10.2011.

Next series of double decker coaches (3050 mm width) are currently under manufacture at RCF, Kapurthala. Train services are planned to be introduced on Delhi-Jaipur and

Design & Quality Audit Report On Landslide and Failure Of Retaining Wall Between Ratnagiri - Nivsar Stations OnRatnagiri - Madgaon Section of KRCL

RCC retaining wall of length 233 meter was constructed during May-2011 for stabilization of Pomendi cutting. But due to heavy rains, about 60 m length of retaining wall between Km-208/99 - 209/050 collapsed on 17.06.11. In terms of Railway Board letter, officials of GE and B&S Directorate of RDSO inspected the affected site of Pomendi cutting. After testing of

Testing Directorate has designed and prepared §Suspension Unit (MSU) of Wheel sets for WAP7/WAG9 Locomotives within specified limits:Excessive axial play in MSU of wheel sets of WAP7/WAG9 locomotives can be attributed to premature failure of MSU bearings. After in depth study of the problems, series of discussions with bearing manufacturers and extensive assembly trials at CLW, Kanchrapara and manufacturers and extensive assembly trials at CLW, Kanchrapara and Bhusawal Workshops, correct procedure of assembly of NDE and DE bearings has been developed and issued in the month of Sep'11. A clamping force of 0.5 kN has been recommended after fitment ofbearing race in case of DE bearing and inner bearing ring in case of NDE till they cool down.

inaugural speech, emphasized

that High Speed Rail Transport

has become more relevant in

present scenario of Global

Warming and environmental concerns, as it consumes

almost one- fifth of fuel in comparison to Air Travel and

can be faster and more convenient than air travel in

many scenarios. Moreover, High Speed Rail

Transport, unlike air travel, is not dependent on fossil

fuel alone, but all the alternate and renewable energy

sources can be tapped for utilisation in High Speed

Rail Transport. Therefore High Speed Rail has a great

future ahead. Indian Railways, in its vision statement

for the year 2020 has envisaged construction of four

dedicated High Speed Rail Corridors between its

major cities. Six corridors have been shortlisted for

pre-feasibility studies. RITES along with M/s Systra

has mentioned in its feasibility study report for Pune-

Mumbai-Ahmedabad corridor that journey time from

Pune to Ahemdabad, a distance of more than 600 kms,

will be reduced to less than 3 hours from existing 12

hours.

Don't feel bad that people remember you only when they need you.Feel privileged that you are like a candle comes to mind when there is darkness in life.

Be good enough to forgive someone. But not stupid enough to trust them again.Anger blows out the lamp of the mind.Time teaches those who have no teacher.
