TTCD 7.8 L6 (Agri)

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 appli-cations.
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.
