What are the six major sensors on a motorcycle?

[DelJayden]

Motorcycle six major sensors include the intake manifold pressure sensor, engine knock sensor, etc. Below is relevant information about these sensors: Introduction: In engines utilizing three-way catalytic converters to reduce exhaust emissions, the oxygen sensor is an essential component. Since the purification capability of the three-way catalyst for CO, HC, and NOx sharply declines once the air-fuel ratio deviates from the theoretical value, an oxygen sensor is installed in the exhaust pipe to detect oxygen concentration in the exhaust. It sends feedback signals to the ECU, which then adjusts the fuel injector's fuel delivery to maintain the air-fuel ratio near the theoretical value. Function: The sensor measures whether there is excess oxygen in the engine's exhaust after combustion—i.e., oxygen content—and converts this information into a voltage signal sent to the engine computer. This enables the engine to achieve closed-loop control targeting the excess air factor, ensuring that the three-way catalytic converter maximizes conversion efficiency for hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx), thereby optimizing the conversion and purification of emission pollutants.
