We developed the PowerTech™ 13.6L engine with a clean-sheet design. This means we designed the product from the ground up, leveraging our best technologies in new ways to meet both market and customer demands.
Our product development approach for the 13.6L resulted in an engine that delivers new levels of reliability, durability, flexibility, and serviceability for a wide array of heavy-duty applications. Not to mention, it’s all wrapped in a compact package that is easy to integrate, simple to maintain, and EPA Final Tier 4 and EU Stage V compliant.
1. Rear gear train
Switching the gear train location from the front of the engine to the rear reduces noise and torsional vibration. Sound intensity is reduced by 50% from the 13.5L, meaning operators can enjoy more comfort. The location also directly improves durability while enhancing operational flexibility, as it enables more gear drive auxiliary power take-off capabilities.
2. Hydraulic lash adjuster
To meet customer needs for fewer and shorter planned maintenance intervals, we utilized hydraulic lash adjusters (HLAs) in the 13.6L engine design. The HLAs are hydraulically operated and self-adjusting, eliminating the need to manually reset the valve lash — a lengthy service process.
3. Next-generation ECU
The engine control unit (ECU) for the 13.6L engine is designed for use without the need for fuel cooling in all operating conditions. This eliminates the need for fuel lines and fittings, simplifying service that requires removing the ECU. In addition, the controller used on the 13.6L utilizes advanced model-based controls that enhance reliability and transient control.
4. Inline IECS
The inline integrated emissions control system (IECS) offers packaging and integration flexibility. It can be mounted horizontally or vertically. Plus, the added flexibility reduces connection points and optimizes thermal management.
5. Integrated wiring harness and sensors
The integrated wiring harness is tighter to the engine and protects wiring during assembly and service. The integrated design and reduced vibration improve reliability compared to engines with wiring harnesses added around existing components, which causes vibration-related issues. Plus, ease of integration is improved because the wiring harness comes already installed.
We designed the 13.6L engine with reliability and durability at its core, so you can count on it to perform in the extremes of rugged off-highway applications — all while surpassing industry and customer expectations. To achieve this, we simplified the design wherever possible, making it compact and reducing the vibration. Total engine lifecycle was a point of emphasis for the 13.6L and was improved by optimizing thermal management systems, fluid efficiency, and more.
Our engineers developed the 13.6L engine to meet power and packaging needs for a wide array of heavy-duty applications. In fact, the 13.6L engine offers more power in a smaller package than its predecessor. Further improving flexibility, it provides the capability to add more pumps with an integrated power take-off, as well as multiple aux drive connections.
The 13.6L engine was engineered specifically with service and repair in mind. In fact, the engineering team worked with the service department as part of the design process — resulting in up to a 50% reduction in mean time to repair (MTTR) from the previous model. Plus, with more than 4,000 John Deere service locations worldwide, you never have to go far to find expert assistance.
