Go there, …The application area of these systems is the compensation of static or slowly changing loads with switching cycles in the range of minutes. Dynamic (delay-free) reactive power compensation systems (i.e. with thyristor-switched capacitors) can prevent or reduce network perturbations such as brief drops in voltage and flicker.

The SCR reactions are usually defined as either “standard SCR” or “fast SCR.” In general, NOx is composed of 95% NO and 5% NO 2; therefore, the reduction reaction is followed in the standard condition.However, in the case of fast SCR reaction, in which NO, NO 2, and NH 3 react in the absence of oxygen, the reaction is completed …

A method is provided for diagnosing a fault in a selective catalytic reduction system having an electric driven transportation device that provide a mass flow of a Diesel Exhaust Fluid into the selective catalytic reduction system.

This will force the computer to reset on its own. Later on, you need to use a code reader, pour in enough DEF, and take the vehicle to a repair shop .

For the controller to have SCR failures, I can offer that these typically come from three main causes: - too much voltage. - too much current. - too much heat. or any combination of the three. The cause for failure can be the result of violating the duty cycle limitations; i.e starting too often without proper elapsed time between starts.The Mack ClearTech SCR System works by directly injecting DEF into the engine's hot exhaust gas stream to reduce NOx emissions to a near zero amount. The injected DEF vaporizes immediately in the exhaust stream and, through elegant chemistry and a catalytic reaction, reduces NOx into harmless nitrogen (N2) and simple water vapor (H2O).Some of the most common problems with the SCR system in Peterbilt trucks include clogged or blocked exhaust filters, faulty wiring, or malfunctioning sensors.
