Description

technical field [0001] The present invention relates to an installation structure of an oxygen concentration sensor, in particular to an installation structure of an oxygen concentration sensor for detecting the oxygen concentration in engine exhaust gas of a motorcycle. Background technique [0002] Generally, in vehicle engines, from the viewpoint of improving the accuracy of fuel control, or the purification of exhaust gas, and low fuel consumption, as a fuel supply system, it has been proposed to use a fuel injection device instead of a carburetor (for example, refer to Patent Document 1 ). Furthermore, in recent years, it has been proposed to use a fuel injection device instead of a carburetor in two-wheeled motorcycles. [0003] Vehicle engines are designed and controlled to burn fuel as efficiently as possible, but due to changes in ambient temperature or air mixing ratio, the combustion cannot be in an ideal state, so the exhaust gas contains harmful carbon monoxide...
