Dongfeng Cummins Engine systems help users perfect interpretation of mechanical instinct

Author : Qijing Date : 2015-8-29 8:46:31
2015 State Ministry promulgated the "National IV" emissions regulations, and from reflecting the state attaches great importance to environmental issues. What the people want, Dongfeng Cummins engine system to meet the "Four Nations" emission standards, both to ensure the stable operation of the engine, but also reduces the user's cost is undoubtedly the key to many users choice!

The perfect combination of engine and SCR system
Engine emission control module, OBD-board diagnostic module, vehicle urea injection module and an SCR catalyst module, Cummins SCR system through these four key modules of the engine and SCR system (emission treatment system) the perfect combination to meet the "National IV" emissions standards at the same time, a strong guarantee of the stability of the engine, allowing the engine to continue to perfect interpretation of its super power.
60 seconds purge remove residual urea
Dongfeng Cummins Engine system uses Cummins emission treatment system to launch the latest research results --EcoFitTM Cummins urea injection systems, compressed air assisted spray techniques. The compressed air is mainly carried weighed urea solution to the nozzle, so that the urea solution can be made better atomization, better participate catalytic reduction.
In addition, after the ignition switch is turned off, the system enters the empty stage, SCR metering jet pump starts automatically purge this phase will last 60 seconds, then the system automatically shut down, so you can pipe in the urea nozzle sweeps away the residue, avoid urea crystallization residue caused due to pipe blockage.
In summary, the Dongfeng Cummins Engine system to fully meet the "National IV" emissions standards, and comprehensive protection of the engine status and pipeline flow, so as to enhance the mechanical life and reduce the user's cost.
