Opel Launches New 2.0-Liter CDTI At 2014 Paris Motor Show
|   Tuesday, September 23, 2014
At the upcoming Paris Motor Show Opel has plans to reveal a new engine, one that will likely please the masses. The increased power, high torque, fuel consumption and low emissions promiseto be the highest level of refinement in its class -we are talking about the new 2-liter turbo diesel engine generation from Opel.

Making its debut on the Insignia and ZafiraTourer at the "Mondial de l'Automobile 2014" in Paris (October 4 to 19), this latest generation engine is another major step in the launching of new powertrainsby Opel.


With an output of 125 kW / 170 hp and substantial torque of 400 Nm, this engine will replace the current 2.0 CDTi 120 kW / 163 HP, located at the top of the Opeldiesel range. Highly efficient, the new engine complies with Euro 6 standards, develops nearly five percent higherpower than its predecessor, and produce 14 percent more torque, while reducing fuel consumption and CO2 emissions.

Extracting as much energy from as little fuel as possible is the key to increased power and fuel economy.With a specific power amount standingat 85 hp per liter, it has the same power density as the new 1.6 CDTI enginegeneration. This engine provides maximum levels of driving enjoyment with minimal impact on the wallets of its customers. The impressive torque of 400 Nm is available across a wide rev range of 1750 to 2500 rpm and maximum power of 125 kW / 170 hp is reached at only 3,750 rpm.

The key to engine performance is a new combustion chamber, reshapedintake ports and new fuel injection system at a pressure of 2000 bar, up to 10 injections per cycle cylinder. These characteristics provide a high power, improved fuel atomization and also contribute to a quieter running. The combustion chamber has been the subject of over 80 computer designsimulations before the best five of them were selected for proper development.

Variable geometry turbocharger (VGT) provides an electric actuation device for variable turbine behavior, providing a 20% faster gain over a vacuum actuation device. Theexceptionally compact structure with a variable geometry turbocharger and intercooler also minimizes the volume of air of the turbocharger and engines,further contributing to the rapid pressureamplification. To ensure sustainability, the turbocharger is water-cooled and equipped with an oil filter mounted on the oilinlet, to further reduce bearing wear.

VGT and the exhaust gas recirculation (EGR) modulehave been designed as a single system in order to ensure optimal efficiency. The EGR module is based on a new concept in steel heat sink which provides a cooling efficiency of almost 90 percent. An integrated water-cooled EGR bypass valve minimizes pressure drop and its closed loop control significantly reduces the nitrogenoxide particles in different driving conditions while improving the management of hydrocarbons and the emission of carbon monoxide.

Available next year, the new 2.0 CDTI is the first unit of a new family of large displacement diesel engines developed in the company by an international team of engineers in Turin and Rüsselsheim, supported by engineers from North America. It will be produced at the Opel engine plant in Kaiserslautern Germany.
