Main Engine 2-Stroke · Main Engines (2-Stroke)
Marine engineers and operators rely on robust and reliable main engines to ensure the smooth operation of their vessels, especially in challenging maritime conditions. Mitsubishi’s 7UEC45LSE engine is a prime example of such a dependable power source, designed to deliver a consistent 7000 kW of power at a low 167 rpm. This engine features a 7-cylinder, 2-stroke configuration with a bore of 450 mm and a stroke of 1350 mm, optimized for efficiency and durability. It operates on heavy fuel oil (HFO) or marine diesel oil (MDO), offering flexibility in fuel sourcing. The engine’s design includes high-efficiency Mitsubishi MET turbochargers and white metal lubricated bearings, ensuring long-term performance and minimal maintenance. Common issues such as exhaust valve wear, piston ring and liner damage, and cooler fouling can be mitigated through regular inspections and proper maintenance protocols outlined by Mitsubishi and other industry experts.
