  1. Product Introduction

Automotive oxygen sensor is the major sensor component in electronic fuel injection engine control system, and is the key part to control automotive exhaust emission, reduce automotive pollution and improve fuel combustion quality. Oxygen sensor is used in the feedback control system of the electronic control fuel injection device, to detect the concentration of oxygen in the exhaust gas and the air fuel ratio. It is also used to monitor theoretical air fuel ratio (14.7:1) combustion in the engine, and to provide feedback signals to the computer.

  1. Product Features

This oxygen sensor downstream is developed with our own technology, and has the following advantage:

Items Leading Tech Normal Assembly Plant in China
Sensor elements 1. Developed and produced using our own technologies, with Pt paste imported from US and zirconia powder from Germany.

2. We employ fully automatic European production equipment to control quality & cost, and ensure performance of the final product is stable.

Bought from random element vendors, with no control over quality consistency.
Air leakage < 0.2 ml/min with longer service life ~2 ml/min, and service life is not guaranteed.
Hexagon Housing Bar material from large scale steel mill Cold heading material from small and medium size steel mill
Corrugated and outer tube Imported from Germany Domestic material
Double protection tube Thickened 310S stainless steel Normal thickness and other material
Laser welding Continuous laser welding machine with a power of 1 KW, which ensures a welding depth of 1.5 mm-2 mm. Alternative welding machine with a power of 300w-500w, which results in insufficient rigidity.
Assembly equipment Fully imported air cylinder with high automation, which ensures smooth riveting Domestic equipment with manual operation
