2024 John Deere Engine & Drivetrains Marine Engines 6090HFM85 Constant Speed

Industrial Marine Engine

Features may include:

• Water-cooled exhaust manifold and turbo to meet surface temperature requirements

• Marine Classification Society fuel hoses, lube and oil hoses

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

• 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.

• An 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.

• 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.
