MAN B&W MC ENGINE: Low-speed two-stroke main engines of the MC/MC-C type have become industry standard in a huge number of ship types. Whether the freight rates rise or fall, MAN B&W MC engine is preferred by the ship owners because of low initial investment cost, Ease of operation & reliability. These engines give flexibility to operate the Engine with low consumption / low load thus controlling the cost of fuel /lub oil. These engine compliance with the latest IMO regulation on NOx limit, measured according to ISO 8178 Test Cycles E2/E3 for Heavy Duty Diesel Engines. The engine is big due to the size 980mm size liner bore. The over head crane and over head space become critical for any overhauling. Professional team can handle these engines well. Some points to note during overhauling  A piston cleaning ring located in the very top of the cylinder liner scrapes off excessive ash and carbon on the piston top land. This to be removed and if possible replaced.  The piston has four ring grooves which are hard chrome plated on both the upper and lower surfaces of the grooves.  Calibrating them is important.  The uppermost piston ring is of the Controlled Pressure Relief type (CPR). This rings found broken on two units. This indicate a special care to be given by ship staff during scavenge inspection.  MAN has modified the TOP PISTON RING . CL Groove positioning is changed from 30 to 60 degrees on each side of the double lap joint to o 90 deg. This distributes the gas flow through the top ring evenly on 180 deg of the ring circumference thereby reducing the thermal load on the oil film.  To ensure safer condition for the mentioned engine, the design standards for the piston ring pack (piston ring no 1 and 4 ) is changed to improve scuffing property.  The 2nd, 3rd, 4th rights are oblique cut. All four rings are alu-coated on the outer surface for running-in.  MAN has changed the stuffing box rings design. Instead of top bronze scrapper ring, a iron ring with steps is used. Lamella and locking steps. This is a new design being used on the ship. Our team completed the overhaul and Stuffing box replacement with ease. -Therefore For any of your ships engine repair kindly contact us .
