D2862LE432 marine diesel engine

The D2862LE432 is a robust, high-output V12 marine diesel engine engineered for demanding duty profiles where uptime, fuel efficiency, and compact installation envelopes matter most. Part of the MAN D D2862 family, the D2862LE432 combines proven high-speed diesel fundamentals with advanced electronic controls and efficient turbocharging to deliver dependable propulsion and auxiliary power across a wide range of vessels and stationary applications. While the series lineage provides context, this page focuses on the technical strengths, use cases, and lifecycle considerations specific to the D2862LE432.

D2862LE432 technical profile and performance

At its core, the D2862LE432 is a 12-cylinder, 90-degree V-configuration diesel engine with a displacement of approximately 24.24 liters. The powerplant leverages high-pressure, electronically controlled common-rail fuel injection for precise metering across the operating range, paired with turbocharging and efficient charge-air cooling. The result is strong low-end torque, rapid transient response, and stable power delivery over sustained operating windows typical of commercial marine duty.

Depending on rating and configuration, the D2862LE432 MAN D marine engine is available with continuous and intermittent power settings suited to propulsion, auxiliary drives, and generator sets. Typical marine speed ranges span approximately 1,500–2,100 rpm, enabling class-compliant propulsion ratings for workboats, ferries, patrol craft, and utility vessels. In stationary roles, the engine can be configured for 50/60 Hz generator sets with optimized fuel maps for partial-load efficiency.

Key technical characteristics include a stiff crankcase with optimized bearing geometry for durability, high-capacity cooling circuits for heat rejection in warm water or tropical climates, and a lubrication system designed for long service intervals under real-world load profiles. Emissions compliance can be addressed with suitable aftertreatment packages to meet IMO Tier II and, when specified with SCR, Tier III requirements in controlled areas. The D2862LE432 diesel engine architecture also supports integration with modern vessel automation for monitoring of fuel rate, load, exhaust temperatures, and predictive maintenance KPIs.
