IAA 2012: Euro 6 engines by Renault Trucks

Renault Trucks presented its Euro VI compliant engines at the IAA show in Hanover. These will equip its trucks when the new standard becomes compulsory in January 2014 (January 2013 for new homologations). For its heavy duty range, Renault Trucks will offer a new six cylinder 11 L engine to be known as the DTI 11. This will be available with three power ratings: 380 hp (1800 Nm), 430 hp (2050 Nm) and 460 hp (2200 Nm). Although its architecture has much in common with the Euro V engine, this latest model breaks new ground with its injection and depollution systems. Injection is based on a common rail system, which offers the main advantage of supplying extremely accurate and high pressure injection, even at low engine speeds. The DTI 11 engine is combined with an SCR post treatment system for reducing polluting emissions to comply with the Euro VI regulation. In order to provide optimal performance, this system must operate at sufficiently high temperature. Renault Trucks meets this requirement by combining different solutions, such as exhaust gases recirculation during engine start-up phases, the use of controlled valves at the intake and the exhaust as well as specific combustion strategies. Finally, the post treatment system is fitted with a particulate filter, as is the case with all Renault Trucks Euro VI engines. This technology has also been chosen for the new six cylinder 13 L engine.

For its medium duty range, Renault Trucks has developed a new four cylinder, 5 L engine, to be known as the DTI 5. It will be available with 210 hp (800 Nm) and 240 hp (900 Nm) versions. As for the DTI 8, this features six cylinders in line with a displacement of 8 L. It will be available in 250 hp (950 Nm), 280 hp (1050 Nm) and 320 hp (1200 Nm) versions. The 5 and 8 L Euro VI engines are fitted with an EGR system. This recycles part of the exhaust gases during combustion and reduces the amount of nitrogen oxide (NOx) produced by the engine. The remaining NOx is then eliminated by catalysis via the SCR system. Finally, the particulate filter enables the vehicle to comply with the very low level of particle emissions demanded by the new standard. Furthermore, this engine is equipped with a common rail type of injection with a maximum pressure of 2,000 bars.
