Deutz chose Intermat 2012 to introduce for the first time the entire range of its engines and DVERT components for the EU Stage IV / US EPA Tier 4 emissions standards. the company states that at the event, it is “demonstrating the future direction for engine technology. The ‘baby’ of this big family is the 30 to 55.4 kW TCD 2.9 L4. Specially developed for very tight and narrow installations, with the range running up to the 240 to 390 kW watercooled TCD 12.0 V6 engine. Variants of some of these new engines will be incorporated into underground mining equipment such as trucks and LHDs going forward, in addition to a range of surface mining machinery.

The ultra-compact, recently developed TCD 2.9 L4 covers the 30 to 55.4 kW power range. Available either as a naturally aspirated or turbocharged engine, with or without charge air cooling, equipped with cooled external exhaust gas recirculation and a common-rail high pressure injection system, the compact 4-cylinder in-line engine offers “high specific power and torque combined with very smooth running characteristics and achieves torque values 50% greater than comparable competitors’ engines.” Powerful and completely redesigned, the TCD 3.6 L4 industrial engine covers the 55.4 to 97 kW power range. With its 510 Nm of torque and maximum power of 97 kW, this compact 4-cylinder engine has penetrated a power category which has hitherto only been served by engines of significantly greater cubic capacity, says Deutz. At engine speeds of 1,400-1,600 rpm, its performance is comparable with that of a supercharged 4.5 litre Tier 3 engine. Rigorous engine downsizing now also provides customers with more installation space for the Tier 4 components.

For the 80 to 115 kW power range, the Deutz portfolio includes the water-cooled TCD 4.1 L4 engine, which generates maximum torque of 610 Nm at engine speeds of 1,400-1,600 rpm. The engine benefits from an exhaust-gas aftertreatment system with a sealed diesel particulate filter and regeneration achieved either by combustion or controlled air throttling. The water-cooled TCD 6.1 L6 covers the 100 to 180 kW power range and, with its maximum torque of 1,000 Nm, promises a performance enhanced by up to 25% compared with its predecessor. This 6-cylinder in-line engine, with its turbocharger and charge air cooler and electronically controlled Deutz common-rail (DCR) high pressure injection system, boasts outstanding economic efficiency, long engine life and extended servicing intervals. The 160 to 250 kW power output of the water-cooled 6-cylinder TCD 7.8 L6 engine makes it the most powerful engine in the medium power category. Equipped with a turbocharger plus charge air cooling, cooled external exhaust gas recirculation and the 2,000 bar Deutz common-rail (DCR) high pressure injection system, this engine, which generates a maximum torque of 1,400 Nm, is designed for high stress applications. Compared with the earlier model, a distinctive feature of the TCD 7.8 is that it uses up to 5% less fuel. Finally, the 240 to 390 kW power range is covered by the water-cooled TCD 12.0 V6 engine. An electronically controlled wastegate turbocharger ensures optimum equipment performance. Designed for high loads, the TCD 12.0 is described as featuring “outstanding ruggedness and long servicing intervals, thus making certain that operating costs are optimised.” Its compact V-design plus front and rear power take-offs with up to three auxiliary drives reduces installation costs and increases the number of potential applications.
