New Requirements for Injectors in China VI Emission Aftertreatment Systems
After the implementation of China VI standards, aftertreatment systems such as DPF and SCR impose higher technical requirements on injectors.
DPF Regeneration Requirements
DPF regeneration requires the injector to perform post-injection during the exhaust stroke to raise exhaust temperature. This demands that the injector have multiple injection capability and high-precision control.
SCR System
The SCR system relies on precise fuel injection quantity to calculate urea injection quantity. Excessive deviation in injection quantity can lead to NOx emissions exceeding standards.
Our Product Upgrade
The new generation common rail injector is fully compatible with China VI aftertreatment systems, supporting up to 9 injections per cycle.
