Deutz Displays Newest Stage IV/Tier 4 Engines at bauma 2013

DEUTZ will present a real highlight at the construction industry’s largest and most important trade fair - bauma in Munich. The company will introduce its new generation of engines that already conform to EU IV and US Tier 4 emissions levels. The power plants illustrate current trends in innovative engine construction: adaptation to the latest emissions standards, downsizing, economy, but all in the usual DEUTZ quality.

The newly developed TCD 2.9 L4 engine features ultra-compact dimensions for installation in tight spaces. Externally cooled exhaust-gas recirculation and a high-pressure common rail system result in maximum performance with minimal emissions. The engine sets new standards in its class with peak output of 5.4 kW and powerful torque of 300Nm.

The turbocharged straight four-cylinder TCD 3.6 L4 covers the range up to 90 kW at Emissions Level IIIB and develops maximum torque of 480 Nm. At level IV, it attains maximum output of 97 kW at maximum torque of 500 Nm, elevating the four-cylinder power plant to a class that is normally served by engines of much greater displacement.

The engine is available without an intercooler at outputs below 56 kW. The TCD 3.6 permits 100% power take-off both front and back and also features two auxiliary PTOs with total torque of up to 310 Nm.

For medium- and heavy-duty applications, the straight four and six-cylinder TCD 4.1 and TCD 6.1 are the engines of choice. The TCD 4.1 covers the range up to 115 kW, developing a maximum torque of 610 Nm. The TCD 6.1 is available at high outputs up to 180 kW and powerful torque of 1,000 Nm.

The TCD 7.8 is the most powerful  mid-class engine. Its maximum output of 250 kW and excellent top torque of 1,400 Nm advances this robust six-cylinder engine to a class that used to be dominated by nine-liter engines. Convincing arguments are its long service life, long service intervals and 3 to 5% lower fuel consumption compared to its Tier 3 predecessor.

Characteristic of V-engines by DEUTZ are their robust nature and low operating costs. Customers like their unrivaled compact design and light weight. The fact that they can fit into very small spaces means that there is more room for other components. The six-cylinder TCD 12.0 delivers maximum output of 390 kW and maximum torque of 2,130 Nm. The eight-cylinder TCD 16.0 rounds out the DEUTZ assortment with 520 kW and top torque of 2,890 Nm.

An SCR system is all that is necessary for it to meet the requirements of EU Level IIIB and US Tier 4 Interim. An electronically controlled turbocharger guarantees top performance. It compact V-design plus front and rear PTOs with up to three auxiliary PTOs minimize installation costs.

DEUTZ will also exhibit completely turnkey, intelligent system solutions in the form of the  TCD 4.1 PowerPack at bauma. The PowerPacks come completely assembled and ready to go on their own integral frame. Their compact construction is ideal for solutions where space is at a premium. The PowerPack on display at bauma comes equipped with a DVERT particle filter.

Supplementing the extensive engine lineup is the modular DEUTZ DVERT system that is compatible with different engine configurations. The DVERT provides an open DVERT Oxidation Catalyst (DOC) for the <4 liter TCD 2.9 and TCD 3.6 engines that can be mounted on the engine as an option. This simple and maintenance-free EAT design is the best solution for light applications below 56 kW. A DVERT particle filter (DPF) is available for markets with stricter regulations. At levels above 56 kW, the TCD 3.6 comes equipped with a DOC+SCR system to conform to Emissions Level IV. Even this EAT design is simply designed and maintenance free. An optional DVERT particle filter (DPF) is available in lieu of the DOC. 

The 4 to 8 liter TCD 6.1 and 7.8 engines come equipped with a  DVERT particle filter and SCR. This design is the best solution for engines with medium and high energy density because it meets all the demands of larger devices in high-performance applications without compromising top performance, maximum torque and engine dynamics.

The TCD 12.0/16.0 engines conform to Emissions Level IV with the SCR-only concept, which means two SCR systems are engaged in series. This DVERT design is the logical development of the DVERT SCR concept for these engines at EU Level IIIB/US EPA Tier 4 Interim. The SCR-only concept makes it possible to dispense with exhaust-gas recirculation for V-engines. The connections and the heat balance on the engines remain nearly unchanged. Complicated and costly modifications during engine installation become unnecessary.

An intelligent Heat Management System (HMS) for regulating exhaust-gas temperature does duty in all Level IV engines >56 kW. Air in the intake manifold is throttled while internal improvements to the engine combine with sophisticated EAT regulation to ensure the high efficiency of the DVERT SCR system and regeneration of the DVERT particle filter under any operating condition.

DEUTZ engines have always been known for their fuel economy. The new DEUTZ engines for EU Level IIIB/US EPA Tier 4 can reduce fuel consumption by another 5 to 10%, depending on the application, the load profile and the output.

With its new Level IV engines, DEUTZ once again sets standards and lowers the fuel consumption of the TCD 6.1 and TCD 7.8 engines by another 3 to 5%. The TCD 3.6, TCD 4.1 and the V-engines maintain the fuel-economy advantage they have at Level III at Level IV as well.

All DEUTZ Level IV engines feature compact design and low noise. Minimal effort is required to install these engines. Optional powerful auxiliary PTOs make them extremely flexible for a great variety of applications.
