Protkarsh Kumar's video: 4500HP WDP4B Diesel Engine Idle Sounds - EMD 16-710G3B Stereo Audio - INDIAN RAILWAYS

Engine idle sound of EMD 16-710G3B prime mover of WDP4B locomotive. Details of the Locomotive and Engine are as follows: Weight of Locomotive: 117T Axle load: 20.2T Engine make and type: 710 G3B Governor: Woodward Weight of engine: 17963 Kg (dry) Number of cylinders: 16 Cylinder formation: 45 degree V type Compression Ratio: 16:1 Horsepower: 4500hp Input to Traction: 4150hp Rated RPM: 954 Injection System: Direct Unit Injector Turbo Supercharger make and type: EMD Model G Weight of turbocharger: 953 Kg Fuel Tank (detachable) capacity: 5000 litres Traction motor gear ratio: 17:77 The WDP4B was the first attempt of the Railways to improve upon the successful WDP4 locomotive. The Bo1-1Bo was found inadequate for hauling 24 coach passenger trains due to the reduced tractive effort. As a result, DLW, reconfigured the chassis to be Co-Co instead. This led to better adhesion with the rails to provide better acceleration with heavy trains. Moreover, the original EMD 710 engine was tweaked to produce an output of 4,500 HP instead of the original 4,000 HP. this Up-rated engine was designated as EMD 16N-710G3B-EC, with an RPM of 910 at Notch-8. This locomotive came to be known as the "GT46PACe". One more important change added to this loco was the inclusion of Blended Brake System. This was added to maximise the use of Dynamic brakes by the loco-pilot and therefore minimise the wear and tear on the fixed brake rigging of the coaches and the locomotive. The addition of blended brake is responsible for the subclass to be designated with a 'B'. Some more features are the widened piggy-face cab profile to aid visibility, change in the Traction Motor blower by installing a higher power motor and increase in the axle load to 20.2 tonnes (19.9 long tons; 22.3 short tons). The locomotive also has a self-load test feature that allows it to test the net output of the engine. In Siemens and EMD systems, the loco has been provided with 2 traction inverters (TCC-1 and TCC-2, for the respective bogies) while in the Medha system, it has 6 traction inverters, one for each traction motor. The WDP4B locomotive is equipped with a turbocharged 16-cylinder 2-stroke 710 G3B diesel engine. This engine has high fuel efficiency and requires low maintenance. The fuel efficiency of this locomotive is better than the existing locomotives. This engine has many modern features like, laser hardened cylinder liners, unit fuel injectors which eliminate the problematic HP tube, inconel valves, hydraulic valve adjuster, durable crankcase and piston structure. The diesel engine drives the main alternator. This locomotive has been designed to run up to maximum operating speed of 140 Km/h on Broad Gauge routes of Indian Railways for passenger service. The tractive effort limiting switch has been provided in the driver cab of the locomotive & may be operated by the crew at the time of requirement.
