Due to the fact that once the air fuel ratio of the mixture deviates from the theoretical air fuel ratio, the purification ability of the ternary catalyst for CO, HC, and NOx will sharply decrease. Therefore, an oxygen sensor is installed in the exhaust pipe to detect the concentration of oxygen in the exhaust and send a feedback signal to the ECU. The ECU then controls the increase or decrease of the fuel injection amount of the fuel injector, thereby controlling the air fuel ratio of the mixture near the theoretical value.

Product advantages - high temperature resistance, corrosion resistance, wear resistance, insulation.

Widely used for controlling the atmosphere of various types of coal combustion, oil combustion, gas combustion, and other furnace bodies.
