Product Details
Motorcycle Oxygen Sensor KGD - ZS - 323
Product Introduction
The KGD - ZS - 323 oxygen sensor is a planar concentration -
difference (switch - type) oxygen sensor applied to motorcycles.
The probe of this model is relatively small in size, making it
suitable for motorcycles with small - to - medium displacements
(200CC - 500CC). Its core component is a chip manufactured using
the HTCC (High - Temperature Co - fired Ceramic) process. This
product can measure whether the oxygen content in the exhaust gas
after the engine combustion is excessive, that is, it tests the
oxygen content in the tail gas and converts the oxygen content into
an electrical signal and transmits it to the engine control unit,
enabling the engine to achieve closed - loop control with the
target of the excess air coefficient (λ = 1). It ensures good
conversion efficiencies for three pollutants in the exhaust gas,
namely hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides
(NOx), to a large extent, transforms and purifies the emission
pollutants, and can save fuel and improve fuel economy at the same
time.
Product Features
- The chip is independently developed and produced.
- Covers multiple series of motorcycle models.
- Stable signal, high accuracy, and long service life.
- High tolerance to moisture and deposits in the exhaust pipe.
- High reliability in harsh operating environments.
