The leader in the new Opel diesel pack, the refined 2.0 CDTI, has just been introduced. The new four-cylinder powerhouse offers impressive torque of 400 Nm and maximum power of 125 kW/170 hp is reached at just 3,750 rpm. It propels the Insignia from 0 to 100 km/h in only nine seconds and to a maximum speed of 225 km/h. This spring, the new 2.0 CDTI will also be introduced in the Zafira Tourer (125 kW/170 hp) and, later, in further Opel models such as the convertible Cascada.
Just like all other Opel diesel engines, the new 2.0 CDTI meets the stringent Euro 6 emission standards. Drivers will be able to enjoy it without any regrets because Opel’s new generation diesels deliver outstanding emission levels comparable to those of a gasoline unit. The main weakness of diesel engines, the emission of nitrogen oxides, is history.
The Insignia comes with Opel’s BlueInjection selective catalytic reduction (SCR) system, which removes nitrogen oxide from the engine’s exhaust gases. Tiny quantities of AdBlue®, a harmless fluid consisting of urea and water, are injected into the exhaust gas flow ahead of the SCR catalyst and downstream of the Diesel Particulate Filter (DPF).
The solution is immediately converted into ammonia (NH3), which is absorbed by the SCR catalyst. Nitrogen oxide in the passing exhaust gas is then selectively reduced to harmless nitrogen and water vapor in a chemical reaction with the ammonia.
