EFI System Pumped Motorcycle Oxygen Sensor

Sustain optimal oxygen content referencing

EFI (Electronic Fuel Injection) System Pumped type meaning ECU (Electronic Control Unit) integrated pumped oxygen circuit by sending pumping voltage to oxygen sensor to withdraw oxygen from the exhaust gas to sensor's body as oxygen content referencing. By comparing between sensor inflow reference and exhaust gas' O2 content, oxygen partial pressure occurs, and Nernst Voltage generate. Then, ECU (Electronic Control Unit) reference the voltage data to determine the status for emission optimization.

Ceradex's system pumped technology enables our sensor to be fully sealed without water, pollutant, and oil intrusion concern. Meanwhile, achieve systematic oxygen pumping that allows higher detection accuracy.
