Engine

There are 12 engine of capacity 8.924 MW each, model of this engine is W20V32, Origin is Wartsila, Finland. It is a four stroke IC engine working as a prime mover of the alternator. The RPM of this engine is 750. Major parts of this engine is

  • Engine Block
  • Crank Shaft
  • Cam shaft
  • Piston
  • Liner
  • Cylinder Head
  • Turbocharger
  • Fuel Pump
  • LO pump.
  • CAC and LO cooler

One complete cycle complete with 2 ravulation of the crank shaft. This 2 revulation completed with the following four stroke.

  • Suction Stroke: in suction stroke fresh air enter into the cylinder from the atmosphere through CA filter, TC and CA cooler. In this stage Piston moves from TDC to BDC. Here 2 intake valve remain open.
  • Compression Stroke: In this stage Piston moves from BDC to TDC and entered fresh air is then compressed to required pressure. Here all valves remain close.
  • Power Stroke and Expansion: During compression before reaching the piston to TDC fuel injection occurred and huge explosion happened and thermal energy converted into mechanical energy which force the piston from TDC to BDC. Here all valves remain close.
  • Exhaust Stroke: In this stage piston moves from BDC to TDC and the combusted product exhausted. Here 2 exhaust valves remain open. Before leaving the exhaust gas it pass through the TC which help to rotate the turbine shaft.

Thus the reciprocating motion converted into rotary motion. And the crank shaft is directly couple with the alternator by coupler and thus alternator starts functioning.
