Deutz presented a comprehensive range of products last week at Bauma that represents a new generation of technology designed to meet the future EU emissions standard IIIB/US EPA Tier 4 interim. The new engines cover a broad performance range from 25 to 520 kW, and combine increased power density with high economic efficiency.
To clarify its technological advance, Deutz said all engines from the next emission standard will bear new product designations. The succinct, self-explanatory engine designation will contain all of the important product information for the customer: the first three letters will provide specific information such as turbocharger, intercooling and fuel type. This will be followed by engine displacement information in liters and the arrangement and number of cylinders. Engines that are already in production for current and previous exhaust gas standards will retain their existing designations.
Under the motto “Deutz modular technologies for new emission standards,” Deutz provided information about new technologies for exhaust gas after-treatment in a symposium at Bauma. Numerous experts answered questions on the subject of exhaust gas aftertreatment and were available to provide information on the new exhaust gas standards, the system module DVERT (Deutz Variable Emissions Reduction Technology) and the newly designed TCD 2.9 L4 engine, which the company exhibited for the first time at Bauma.
Available in both normally aspirated and turbocharged versions (with or without a charge air intercooler) and equipped with cooled external exhaust gas recirculation and common rail high-pressure injection with 1,600 bar, the ultracompact 4-cylinder 2.9-liter-series in-line engine covers a performance range from 25 to 56 kW. The engine achieves its maximum torque of 300 Nm at 1,600 rpm. The compact engine, which was developed especially for very short and tight installations, offers high specific performance and torque while at the same time providing very refined running.
There is a full range of customer-specific options, including efficient lateral auxiliary drives and mass balancing shafts. A modular exhaust gas after-treatment system is tailored to the requirements of industrial machinery in respect of its compact design and cost efficiency: the maintenance-free, cost-effective diesel oxidation catalytic converter (DOC) and particle oxidation catalytic converter (DOC + POC) cater for most applications, with a closed DPF option (diesel particle filter) also available. Series production will begin by mid 2012.
Deutz covers the 50 to 85 kW performance range with another newly developed engine, the TCD 3.6 L4, which achieves a maximum torque of 400 Nm at a speed of 1,400 to 1,600 rpm. The water-cooled, turbocharged 4-cylinder engine, with or without a charge air intercooler and cooled external exhaust gas recirculation is equipped with a common rail system with 1,600 bar, while boasting a low power to weight ratio and high power density. Long service intervals also ensure low maintenance costs.
With the advent of the new exhaust gas standard, the two newly developed engines TCD 2.9 L4 and TCD 3.6 L4 will establish links with the Deutz 2011-series, which will remain in production for the current emission standard.
“Our latest developments combine maximum customer benefit with minimum operating costs,” said Gino Mario Biondi, Deutz managing director of development and production. “It means that we will establish and build on our position as the leader in technology.”
Originally founded as N.A. Otto & Cie., Cologne, Germany-based Deutz AG is one of the world’s leading independent engine manufacturers.
