Main Engine 4-Stroke · Main Engines (4-Stroke)
This marine engine is commonly found powering large vessels such as cargo ships and naval craft, where its robust design and high power output are critical for efficient operation. The MTU 20V4000 M05-N engine delivers a continuous power of 3100 kW at 1800 RPM, utilizing a 4-stroke spark-ignited configuration fueled by liquefied natural gas (LNG). With a bore of 165 mm and a stroke of 190 mm, it offers a reliable and efficient solution for marine propulsion. The engine features a common rail injection system and sequential turbocharging with two water-cooled turbochargers, ensuring optimal performance and compliance with IMO Tier II and EPA Tier 4 emissions standards. Regular maintenance checks are essential to prevent common issues such as deteriorating fuel quality, turbocharger failures due to lubrication problems, and cooling system neglect leading to overheating and cavitation.
