The engine room directly behind the driver's cab - The green Cummins KV 16 prime mover (derated to 1400 HP, V16), the BHEL traction alternator, exhaust plumbing (silver), air intake (black) from the radiator room (behind the far side wall), the belt driven Elgi air compressor with the shiny can type air filter and the heat exchanger and the red piping leading to a hydraulic engine room ventilation fan set in the roof. Towards the right of this location (on the other side of the alternator) is a KEC 110 V Alternator (also belt driven from the prime mover) which is used to charge the lighting batteries of the HHPDEMU rake. The power car has four traction motors and the main rectifier is located underfloor. The snappy acceleration of the HHPDEMU comes from the high power to weight ratio and the electronic governor for the engine/ alternator. The entire rake has a self leveling pneumatic suspension. The radiator room contain the side mounted radiator screens with two powerful 40 " hydraulic radiator vent fans in the roof. |
