Compact & powerful, the 5 Series is powered by the new Deutz TCD 3.6 L04, a 3,620 cc four cylinder unit which earned the prize as best engine in its class at BAUMA 2010.
By adopting the most advanced engine technology the minimum specific fuel consumption of just 210 g/kWh - an outstanding figure for an engine of this size. To achieve these statistics the new Deutz powertrain utilises electronically controlled CommonRail injection, a turbocharger with intercooler, wastegate valve and a proportional speed viscostatic fan.
These engines are designed specifically for agricultural applications, as demonstrated by a torque curve which remains close to maximum torque from 1,200 to 1,900 rpm - the engine speed range used in the majority of agricultural applications - and a torque reserve of more than 30%.
The engineering and design solutions adopted to maximise power and efficiency include electronically controlled common rail fuel injection, turbo-intercooler forced induction, a waste-gate valve and a proportional viscostatic fan. The electronically controlled, liquid cooled, exhaust gas recirculation system (EGR) and special diesel oxidation catalyst (DOC) catalytic converter ensure compliance with Tier 4i standards.
DOC is a special catalytic converter which catalyses chemical reactions within the exhaust gases on contact to transform them into harmless substances. DOC eliminates the drawbacks of the FAP system (which produces harmful exhaust back-pressures and necessitates energy-costly active regeneration cycles) and the SCR catalytic converter (which needs an additive such as AdBlue to trigger selective catalytic reduction), is maintenance-free and small enough for installation on compact tractors, offering the ideal solution to protect the environment. Just like its siblings with conventional transmissions, the TTV variant of the 5 Series is the ideal agricultural machine, with a practically flat torque curve offering close to maximum torque throughout a range from 1200 to 1900 rpm - the operating range used in the majority of agricultural applications. At higher engine speeds, power remains constant within the band from 1800 to 2200 rpm, for progressive, smooth operation even during jobs with very high power demands. The fully electronic engine governor delivers only the power effectively needed for the job in hand to eliminate fuel wastage.
