The new Opel 1.6-liter diesel engine
Opel continues the fundamental renewal of its powertrain portfolio with an all-new four-cylinder, turbo-diesel engine. The second family of new downsized power units to be introduced after the gasoline 1.6-liter SIDI ECOTEC, the 1.6-liter CDTI ECOTEC diesels will replace existing 1.7-liter engines and certain lower powered versions of the 2.0-liter range.
Featuring closed-loop combustion control and an aluminum block, the new 1.6 CDTI ECOTEC is the first diesel from Opel to comply with future Euro 6 emissions requirements. The engine will be available in a variety of power outputs across several carlines.
Attenuation of noise, vibration and harshness, high power/torque density and low fuel consumption were the main development objectives. Initially maximum power and torque have been increased versus the 1.7-liter engine to 136 hp and 320 Newton meters respectively, while fuel consumption has been reduced by up to 10 percent compared with similarly powerful 2.0-liter diesels.
The comprehensive renewal of our powertrain portfolio continues at wide-open throttle. Our new 1.6-liter diesel will set benchmarks for refinement, performance and environmental compatibility. By the end of this year we will have launched three all-new generations of gasoline and diesel engines, as part of our roll-out of 23 new models and 13 new powertrains by 2016.– Dr. Thomas Sedran, Deputy Chairman of the Opel Management Board.
The new 1.6-liter diesel and its innovative engine control unit have been entirely developed in-house by a global team of engineers in Turin, Ruesselsheim and the USA. This approach has enabled a comprehensive system optimization from the very beginning of the design process. Beginning in spring, the 1.6 CDTI ECOTEC will be manufactured at the same “flex plant” as the new 1.6-liter gasoline engine, in Szentgotthard in Hungary.
Romain Nicolas opinion:
I’m curious to know how did Opel managed to industrialize closed loop combustion concept. A lot of other manufacturers are working on it but as advanced engineering projects, and Opel is releasing the second engine generation with this technology. What are the benefits of closed loop combustion? What are the drawbacks?
