• The urea tank is installed to the vehicle rear.
• The urea tank capacity is
15.5 L {16.4 US qt, 13.6 lmp qt}.
• High-density polyethylene has been adopted as the material for the urea tank.
• The pot is built into the urea tank.
• The urea temperature sensor, the urea level sensor, and the urea tank heater are integrated into the pot. Explanations of each part are as follows:
Urea temperature sensor
-
Outline
-
• The urea temperature sensor detects the AdBlue® temperature from the urea tank.
-
Purpose
-
• Prediction of AdBlue® freezing
Urea level sensor
-
Outline
-
• The urea level sensor detects the remaining amount of AdBlue® in the urea tank.
-
Purpose
-
• Prevents a decrease of NOx purification efficiency if the system runs out of AdBlue® aqueous solution.
Urea tank heater
-
Outline
-
• The urea tank heater heats the AdBlue®.
-
Purpose
-
• Prevents freezing of the AdBlue®
