The Nozzle Heater Relay in the after-treatment regeneration device is responsible for managing the power supply to the nozzle heater. During the regeneration process, the heater increases the temperature of the exhaust gases, ensuring optimal conditions for soot oxidation in the diesel particulate filter. The relay ensures accurate timing and reliable switching of electrical current to the heater, preventing overheating and power issues. It helps maintain consistent exhaust temperature levels, enhancing the efficiency of the after-treatment system.Attributes:• Activates the nozzle heater during the exhaust regeneration process.• Improves fuel burn efficiency by maintaining proper heater function.• Aids in maintaining exhaust system temperature during regeneration.• Prevents incomplete regeneration by ensuring heater activation at required thresholds.Applications: The Nozzle Heater Relay is located near the nozzle and control system in the after-treatment unit, providing controlled power to the heater during regeneration.
