Features
Run pumps, winches, deck cranes, hydraulics, and generators with a Tier 3 John Deere variable speed industrial auxiliary engine.
Expand All4-valve cylinder head
- The 4-valve cylinder head, with U-flow head design, provides excellent airflow resulting in greater low-speed torque and better transient response.
High-pressure common-rail (HPCR) and engine control unit (ECU)
- The HPCR fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures, up to 1600 bar (23,000 psi). It also controls fuel injection timing and provides precise control for the start, duration, and end of the injection.
Cooled exhaust gas recirculation (EGR)
- EGR cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx.
Variable geometry turbocharger (VGT)
- Varies exhaust pressure based on load and speed to ensure proper EGR flow; greater low-speed torque, quicker transient response, higher peak torque, and best-in-class fuel economy.
Air-to-air aftercooled
- 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.
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; solid conduit and "T" connectors reduce wiring stress and provide greater durability and improved appearance.
- Factory-installed, engine mounted ECU or remote-mounted ECU comes with 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
