Abstract
A sensor mounting structure for an engine is provided. The sensor mounting structure offers a greater flexibility in mounting a sensor which detects an operation of an actuation member disposed at an inner wall spaced apart from an outer wall of a cylinder head of a valve gear. A sensor mounting structure for an engine includes a valve gear provided at a cylinder head and a sensor detecting an operation of the valve gear. The sensor is mounted on a sensor mounting hole formed at a head inner wall of the cylinder head covered with a cylinder head cover.
Claims17
A sensor mounting structure for an engine including:
- a crankcase, a cylinder block having a plurality of cylinders formed therein, a cylinder head, and a cylinder head cover stacked on and fastened integrally with the crankcase in a direction of a cylinder axis which is a central axis of each of the cylinders of the engine, the sensor mounting structure comprising:
- a valve gear provided at the cylinder head;
- a sensor for detecting an operation of the valve gear, the sensor being mounted in a sensor mounting hole formed in a head inner wall which is a part of the cylinder head, the inner wall being separated from and covered with the cylinder head cover, and
- a tubular member interposed between an outer surface of the cylinder head cover and the head inner wall, the tubular member having a first end opening opened to an area outside of the cylinder head cover, and a second end opening opposed to the sensor mounting hole.
A sensor mounting structure for an engine including a crankcase, a cylinder block having a plurality of cylinders formed therein, a cylinder head, and a cylinder head cover stacked on and fastened integrally with the crankcase in a direction of a cylinder axis which is a central axis of each of the cylinders of the engine, the sensor mounting structure comprising:
- a valve gear provided at the cylinder head;
- and
- a sensor for detecting an operation of the valve gear, the sensor being mounted in a sensor mounting hole formed in a head inner wall of the cylinder head covered with the cylinder head cover,
- wherein:
- the engine is an inline multi-cylinder engine,
- a spark plug is mounted on the cylinder head for each of the cylinders, and
- the sensor is disposed between two adjacent ones of the spark plugs.
