Constant-Speed Auxiliary & Generator Engine

Features

Optional low rpm operation

A lower speed option provides the user the ability to start the engine without going to the gen-set rated speed and allows the user to clutch in an accessory that may be driven by the engine.

4-valve cylinder head

Excellent airflow through 4-valve cylinder head delivers greater low-speed torque and better transient response time.

High-pressure common-rail (HPCR)

The HPCR fuel system provides variable common-rail pressure, multiple injections, and controls fuel injection timing and provides precise control for the start, duration, and end of injection.

Water-cooled exhaust manifold

Integrated components eliminate external hoses and fittings. Wet exhaust manifold creates a cooler and quieter environment for passengers and crew.

Turbocharged with air-to-seawater aftercooling

Cooler turbocharger operation enables higher ratings and efficiencies for applications that require high power or speed.

Replaceable cylinder liners

Replaceable wet-type cylinder liners are precision-machined and hardened for long life. Allows engine to be rebuilt to original specifications.

Electronic engine control unit (ECU)

Advanced fault code diagnostics and customizable engine protections ensure reliability and uptime. Provides highly customizable features and trim to integrate your vessel.

Heat exchanger

Multiple service options

Either-side oil fill/dipstick combinations and remote oil and fuel filter options are available for easier service access.
