John Deere Engine 11 - 6090HFM85 Constant Speed - Industrial Auxiliary Engine

6090HFM85 9.0L PowerTech™ engine has 238 kW (325 hp) power rating operating @ 1800 rpm. It is configured to deliver best performance for patrol craft, launches, work boats, fishing boats, trawler yachts, and sportfishing boats.

Key Features

ABS type approved for use on classed & inspected vessel

• Water-cooled exhaust manifold and turbo to meet surface temperature requirements
• Marine Classification Society approved fuel hoses, lube, and oil hoses

4-valve cylinder head

• The 4-valve cylinder head provides excellent airflow resulting in greater low-speed torque and better transient response.
• Cross flow design

Electronic unit injector (EUI) and engine control unit (ECU)

• The EUI fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures, up to 2000 bar (29,000 psi). It also controls fuel injection timing and provides precise control for start, duration, and end of injection.

Air-to-air aftercooled

This is the most efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs.

John Deere electronic engine controls

• Electronic engine controls monitor critical engine functions, providing warning and/or shutdown to prevent costly engine repairs and eliminate the need for add-on governing components all lowering total installed costs. Snapshot diagnostic data that can be retrieved using commonly available diagnostic service tools.
• Controls utilize common wiring interface connector for vehicles or available OEM instrumentation packages; new solid conduit and “T” connectors to reduce wiring stress and provide greater durability and improved appearance.
• Factory-installed, engine mounted ECU and wiring harness and associated components. Industry- standard SAE J1939 interface communicates with other vehicle systems, eliminating redundant sensors and reducing vehicle installed cost.

Additional features

• Gear-driven auxiliary drives
• Self-adjusting poly-vee fan drive
• Single-piece low friction piston
• Low-pressure fuel system with "auto-prime" feature
• Directed top-liner cooling

John Deere Engine 12 - 6090SFM85 - Marine Generator Drive Engine

This 9.0L PowerTech™ marine engine boasts dual-circuit keel-cooled applications [water-cooled exhaust manifold and air-to-seawater aftercooling] for improved fuel economy and long-lasting engine life. It offers 222-278 kW (297-373 hp) power rating ideal for patrol craft, launches, work boats, fishing boats, trawler yachts, and sportfishing boats.

Key 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

High-capacity heat exchanger provides reliable operation in adverse conditions.

Multiple service options

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