Yep, yan ang sulzer diesel engine! We use 21 of those on our power plant located at Bauang La Union-Wartsila is our supplier. It generates a total of 225MW which provides backup power to the whole of Luzon Grid. basically pareho rin ang concept if you will compare it sa diesel engines sa car...warm-up during start-ups then cooldown process during shut downs. Oh and bby the way, they use different oils sa warm-ups, normal running condition, and shutdown process!
