7L27/38

Designed for long-term reliability and minimal downtime, the MAN 7L27/38 is a robust propulsion engine that ensures consistent performance across various load conditions. This four-stroke marine system offers quick acceleration and immediate load response, making it ideal for applications where reliability and efficiency are paramount. The engine's proven design minimizes unscheduled maintenance, extending the time between overhauls. With a bore of 270 mm and a stroke of 380 mm, each cylinder has a swept volume of 21.76 dm³. Available in configurations with 6, 7, 8, or 9 cylinders, the MAN 7L27/38 can be tailored to specific vessel requirements. The engine is equipped with a high-efficiency constant pressure turbocharging system from the MAN TCR series and an integrated safety and control system known as MAN SaCoS one. Additionally, it features a conventional main injection system for optimal fuel consumption, which meets IMO Tier II emission standards. For even greater efficiency, a variable injection system can be added to achieve lower fuel consumption while complying with stringent emissions regulations. The 7L27/38 also includes a 100% PTO on the front-end, enabling the installation of fire-fighting equipment and jet assist for improved load response and startup time. With a power-to-weight ratio ranging from 12.0 to 13.24 kg/kW, this engine delivers a balance of performance and reliability that meets the demands of modern maritime operations.
