Deutz will be exhibiting its first off-highway hybrid concept at the Intermat international exhibition for construction and infrastructure. Combining a TCD 2.9 diesel engine and a 55 kW electric motor, the new concept is the first tangible result of the E-DEUTZ program established in 2017, and opens up significant potential for efficiency gains in drivetrain technology. Deutz will also be presenting an EU Stage V certified engine range and new in-line engines with capacities from 9 to 18 liters, while the service business will be presenting its free service app ‘DEUTZ Connect’ for remote engine diagnosis.

The E-DEUTZ strategy combines Deutz’s low-emission engines with electric drives and its launch represents the company’s next decisive step forward. In September 2017, Deutz also acquired Torqeedo GmbH, the global market leader and system solution specialist for integrated electric and hybrid drives for boats. Deutz will harness Torqeedo’s extensive know-how to benefit future developments in its off-highway business.

To illustrate this technology transfer at the Paris show, DEUTZ will be displaying its concept of a modular, scalable hybrid drive consisting of a TCD 2.9 diesel engine and an e-motor, plus power electronics and a battery pack specially designed for this combination. The e-motor and diesel each deliver 55 kW, producing a combined maximum system output of 110 kW. The lithium-ion battery has a capacity of 40 kWh at 400 volts. The mechanical connection between the e-motor and the diesel engine is achieved by means of a transmission with integrated decoupler, which allows the diesel engine to be disconnected from the electrical system and provides the option of powering the vehicle purely by electricity. The increased maximum system output makes it possible to use a combustion engine with a lower capacity and output than a pure combustion drive in the same output class. A further benefit of hybridisation is the option to integrate additional fuel-saving functions such as start-stop or crankshaft starting, and for power takeoffs to run on electricity in future.

In addition to the electrification of its drive systems, Deutz will also be demonstrating its expertise in exhaust after treatment in Paris. In 2017, Deutz was the world’s first engine manufacturer to be given a certificate for the new EU Stage V emissions standard that comes into effect in 2019. The Deutz TTCD 6.1 received the first certificate and was followed by other models which were immediately marketed under the ‘Stage V certified’ seal. The particular added value for customers is that switching from the current EU Stage IV to Stage V requires no additional installation space, thus avoiding expensive modifications to customers’ equipment. By being the first to obtain EU Stage V certification, DEUTZ is re-affirming its environmental promise and positioning itself as an engine manufacturer with an eco-friendly focus.

From 2019, Deutz will also be expanding its portfolio in the higher output range, with four new in-line engines of between 9 and 18 liters capacity. The TCD 9.0 four-cylinder engine and the TCD 12.0 / 13.5 and 18.0 six-cylinder models deliver power output of between 300 and 620 kW and will be aimed in particular at heavy-duty off-highway applications. The models in the TCD 9.0 to 13.5 product range are part of a family platform concept with a standardised customer interface and identical front and rear sides, which make it considerably easier to install and service the engines. The Deutz TCD 9.0 has already won two awards: ‘DIESEL’ magazine named it ‘DIESEL OF THE YEAR’ and it was included among OEM Off-Highway magazine’s ‘Top Ten New Products of 2017’.

Deutz is extending its product offering in the lower power output range, too. From 2019, based on the successful four-cylinder TCD 2.9 (30 to 75 kW), there will be a three-cylinder variant, the TCD 2.2, ranging in output from 22 to 56 kW. Both these diesel engines will also be available as liquefied petroleum gas (LPG) versions, named G 2.2 and G 2.9. All the variants will be based on the same engine platform, generating extensive synergy effects. These drives will represent a further option, in particular for low-load applications in the material handling and compact construction equipment field.
