BY MIKE OSENGA With the first steps of Tier 4 interim in the U.S., as well as EU Stage 3b off-high- way diesel emissions regulations looming, the recent Bauma exhibition in Munich, Germany, was a major event for Germany’s Deutz AG and its Americas subsidiary Deutz Corp., Atlanta, Ga. Bauma is almost always a “home game” for Deutz, but with the U.S. and EU emissions regulations coming soon, the triennial show in Munich took on an even greater meaning. And Deutz came out strongly, mak- ing a significant and very aggressive series of product introductions at Bauma, including two brand new engine lines, the TCD 2. 9 and the TCD 3. 6 diesels. Along with the two new engine lines, Deutz showed its complete Tier 4 interim compliant port- folio — five engine families in total. Interestingly, Deutz also used Bauma to show some of its Tier 4 final strategies. “We are really early in announcing our strategy to our customers,” said Georg Diderich, senior vice president corporate man- agement. “They need to know what’s in front of them. Our decisions were made very early, our strategies were set very early, and we think that’s a real competitive advantage.” To differentiate its new Tier 4 product line, Deutz is also introducing new engine designations. The new nomen- clature consists of the displacement of the engine, followed by number of cylin- ders and the configuration, and will be applied to all new engines starting from Tier 4 intertim introductions from 2011 onward. Deutz said that all existing seri- al products will keep their previous des- ignations. An accompanying table provides further details. The Deutz Tier 4 product line starts with the TCD 2. 9 range, a completely new diesel engine line developed specifi- cally for the con- struction and agricul- tural industry, as well as other off-highway uses. The 2. 9 L, four- cylinder, inline engines were developed for the 33 to under- 75 hp power range. The TCD 2. 9 L4 engines are liquid-cooled, four- cylinder inline diesels, which will be introduced with outputs from 33 to 74. 9 hp at 2600 rpm. Naturally aspirated, turbocharged and charge- air cooled configurations will be available. The new TCD 2. 9 engines will have a high-pressure ( 23,000 psi) common rail fuel system, with a Bosch high- pressure fuel pump and EMR 4 elec- tronic control unit (ECU), as well as wastegate turbochargers on those configurations. The design of the TCD 2. 9 also includes a rear geartrain and optional balancer to reduce noise and vibra- tion. The inline cylinders have a par- ent bore, and water cooling is via an integrated, thermostat-controlled by- pass system. The crankcase, which has a closed breather system, is grey cast-iron, two-valves-per-cylinder U- flow design. At 1600 rpm, the naturally aspirated model TCD 2. 9 has a maximum torque of 108 lb.ft., while the tur- bocharged and charge-air cooled ver- sions have a maximum torque of 186 lb.ft. at the same speed. The TCD 2. 9 engines have a bore and stroke of 92 mm x 110 mm, and weigh 463 to 496 lb. depending on the configuration. The new engines will be manufac- tured at the Deutz Cologne, Germany, facility. Units have been out on test and serial production is scheduled to begin in June 2012, six months before the emissions regulations for that out- put band begin. The smallest of the two new engine ranges being intro- duced by Deutz at Bauma is the TCD 2. 9 range, developed specifically for the con- struction and agricultural industry, as well as other off-highway uses. The 2. 9 L, four- cylinder, inline engines were developed for the 33 to under- 75 hp power range.
