These are parts belonging to the chain of mechatronic components for an effective emission technology and are partly fitted with integrated electronic controls. They will be installed in two-liter diesel engines destined for SUVs, pick-ups, and delivery vans. The control valves produce a pressure drop in the engine for recirculation of the exhaust gases and on compression ignition diesel engines ensure efficient and effective engine switch-off. The actuators on the intake manifold adjust the tumble valves in the manifold for improved air/fuel mixture in the combustion chamber. The electric switchover valves are needed for regulating the EGR cooler bypass while also ensuring reduced NOx emissions.
A part of the valves will sourced locally from Pierburg's Chinese plant in Kunshan starting from 2018, another from the German plant in Berlin. The components ordered represent state-of-the-art exhaust-gas engineering and also serve to ensure compliance with strict Chinese emission standards comparable to the Euro 5 and Euro 6 regulations. The KSPG subsidiary Pierburg is thus once again documenting its competence in emission reduction by introducing its longstanding expertise on this subject into the Chinese auto market.
