Key Features
Engine for agricultural machinery. Water-cooled 6-cylinder in-line engine with turbocharging and charge air cooling.
- Two-stage turbocharging and cooled external exhaust gas recirculation from EU Stage IV / US EPA Tier 4.
- Engine and exhaust aftertreatment (EAT) are optimised for highest total system efficiency and thus ensure minimised fuel and total operating costs.
- The powerful DEUTZ Common Rail (DCR®) injection system and the electronic engine control (EMR 4) with intelligent link to the drive management ensure optimum engine performance at low fuel consumption.
- Extremely compact DPF, which makes installation easier where there is limited space.
- 100% power take-off at flywheel and front end.
- The extremely compact engine design with structural oil pan and a customer-oriented, modular system of optional add-on parts reduce the installation costs and increase the number of applications.
- Consistent installation and connection dimensions of the engine facilitate the changeover of existing installations to the next stage of the emission legislation.
- Best cold starting performance even under extreme conditions.
- 500 h oil change intervals and easy changing of the engine fluids reduce the running costs and increase the availability of the machinery.
- The engines meet the requirements of the EU Stage IIIB and US EPA Tier 4 interim with SCR. Additionally for EU Stage IV / US Tier 4 with DVERT® Particle filter (DPF). A variant without EAT is available as an option for less regulated markets.
