Deutz TCD 5.0 suits engine downsizing

TCD 5.0 is the name given to the latest engine from 201 Deutz. The five-litre, four-cylinder engine fills a gap between the 4.1litre TCD 4.1 and 6.1litre TCD 6.1 engines. The new engine offers a power rating from 100-150kW but occupies the same physical size as the smaller capacity TCD 4.1.

Key engine developments for the TCD 5.0 include an overhead camshaft design with maintenance-free hydraulic tappets. Deutz said that this development offers scope for variable valve timing in the future, along with improved thermodynamics and better heat management for exhaust after-treatment packages.

The company said the TCD 5.0 is an option for those seeking to substitute a larger engine without a sacrifice in power - or it can offer a performance increase for existing engines of the same physical size.

Using a single turbocharger and charge-air cooling, this latest addition to the TCD engine portfolio uses cooled EGR along with DOC, DPF and SCR to meet Stage V emissions regulations. However, integration of the EGR mechanism as part of the engine block makes the engine easily adapted – using blanking plates and software upgrades - to less stringent markets.
Deutz said a higher power version of the TCD 5.0 will follow.
