Main Engine 4-Stroke · Main Engines (4-Stroke)
The M32E family of engines operates on a 7-cylinder, 4-stroke design with a bore of 320 mm and a stroke that varies between 460 mm (for the M32E) and 460 mm (for the M32C). Operating at a constant speed range of 720 to 750 rpm, these engines are capable of delivering approximately 550 kW per cylinder. The MaK 7LM32E model operates on heavy fuel oil (HFO), marine gasoil (MGO), and low-sulfur diesel, conforming to IMO Tier II/EPA Tier 2 emission standards. With a fuel efficiency range of about 190 to 210 grams per kilowatt-hour, the M32E can achieve up to 24 g/kWh with the Part Load Kit. Known for their longevity, MaK engines recommend inspecting components such as piston rings every 10,000 hours and valve tappets at 10,000 hours. Regular checks include visual inspections for carbon deposits, oil consumption trends, cylinder wear measurements, and compression tests to ensure optimal performance and reliability.
