How does SCR work?

• SCR works by reducing the amount of oxygen in the exhaust stream.

• SCR works by injecting a urea-based solution into the fuel stream.

• SCR works by using a catalyst to convert NOx into harmful gases.

• SCR works by injecting a urea-based solution into the exhaust stream to convert NOx into harmless gases.

What is the role of a gate signal in SCR operation?

• The gate signal triggers the SCR into conduction.

• The gate signal regulates the voltage across the SCR.

• The gate signal turns off the SCR.

• The gate signal increases the resistance of the SCR.

What is the difference between forward and reverse blocking in SCR?

• The difference between forward and reverse blocking in SCR is the current flowing through the anode and cathode.

• The difference between forward and reverse blocking in SCR is the size of the SCR.

• The difference between forward and reverse blocking in SCR is the temperature at which the SCR operates.

• The difference between forward and reverse blocking in SCR is the polarity of the voltage applied to the anode and cathode.

What is the effect of temperature on SCR operation?

• Temperature affects the conductivity of the semiconductor material used in the SCR.

• Temperature has no effect on SCR operation.

• Higher temperature increases the resistance of the SCR.

• Lower temperature increases the conductivity of the semiconductor material used in the SCR.
