ABSTRACT:
An engine oxygen concentration sensor mounting structure in which an oxygen concentration sensor is mounted in a collector exhaust pipe connected to an outlet of an exhaust manifold having a plurality of exhaust single pipes. When a straight line is drawn from a detection part of the oxygen concentration sensor positioned within the collector exhaust pipe so as to be parallel to a section of a centerline of the exhaust pipe closest to the detection part, the straight line passes outside the outlet of the exhaust manifold. This allows the exhaust gases discharged from the exhaust manifold to be sufficiently mixed within the curved exhaust pipe and differences in length of the plurality of the exhaust single pipes to be compensated for. Thus, accurate detection by the oxygen concentration sensor can be secured, even if the lengths of a plurality of exhaust single pipes of the exhaust manifold are nonuniform.
