Compared to the 2.0 CDTI engine with similar power also available in the Zafira Tourer, it offers a 10 percent reduction in fuel consumption and CO2 emissions. That means combined cycle fuel consumption of just 4.1 l/100 km and 109 g/km CO2, figures no other 7-seater compact monocab with similar output can match.In smaller vehicle applications, sub 4.0 l/100 km fuel consumption and CO2 emissions near or below 100 g/km are expected.
With Opel’s BlueInjection selective catalytic reduction (SCR) system enabling compliance with Euro 6 emissions standards (effective September 2015), the 1.6 CDTI is as clean as a gasoline engine in its operation.
Like its gasoline counterpart, the 1.6 CDTI also benefits from a series of ‘sound engineering’ measures to minimize noise, vibration and harshness. It has recorded the lowest in-vehicle noise ratings when tested with the Zafira Tourer against other vehicles using 1.6-liter turbo diesel engines.
A high pressure, common-rail fuel system, allied to closed-loop combustion control and strong intake charging from a variable geometry turbocharger (VGT) are key technical features. These functions, and many more, are controlled by the 1.6 CDTI’s sophisticated engine control unit, developed in-house by General Motors. This state-of-the-art ECU, engineered in Italy, Germany and the United States, will be used in all of Opel’s future four-cylinder diesel engines.
