Description

[0001]
BACKGROUND OF THE INVENTION
The present invention provides an engine detection system including an oil injection passage for injecting oil into a crankcase, a detecting means for detecting the amount of oil injected from the oil injection passage, and an oil extraction port for extracting oil from the crankcase. It relates to an oil device.
[0002]
[Prior art]
As an engine oil inspection device, for example, Japanese Utility Model Laid-Open No. 4-82310 “oil supply and oil inspection device for engine oil” is known.
According to FIG. 1 of the same publication, the above-described technique is such that an oil filler pipe 3 is attached to an oil filler port 1 of an engine via a joint 2, and a flexible oil level gauge 4 is detachably attached to the oil filler pipe 3. It is a thing.
[0003]
[Problems to be solved by the invention]
However, the engine oil supply and oil inspection device removes the entire flexible oil level gauge 4 from the oil filler pipe 3 during oil inspection. Next, the engine oil adhering to the flexible oil level gauge 4 is wiped off. Then, the flexible oil level gauge 4 is returned to the oil filler pipe 3. Again, the entire flexible oil level gauge 4 is removed from the oil filler pipe 3, and the position of the engine oil adhering to it is observed to complete the oil inspection operation.
This makes the oil inspection work complicated and takes time and labor before the start of work. I would like to complete the start-up inspection more easily.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide an oil inspection device for an engine that can easily perform an oil inspection operation.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, an oil inspection device for an engine according to claim 1 comprises an oil injection passage for injecting oil into the crankcase, a detecting means for detecting the amount of oil injected from the oil injection passage, and an oil for the crankcase. In an engine equipped with an oil drain port for draining
The oil injection passage is composed of a passage that extends substantially horizontally from the crankcase and a passage that rises substantially perpendicular to the passage, and the detecting means is formed in the passage where the oil injection passage rises to notify the upper limit level of the oil amount. a first protrusion, a second protrusion formed on the passage rises the oil filler path to inform the lower level of the oil level, Ri Tona, first projection is disposed opposite to the second protrusion In addition, the first and second protrusions are provided on a surface located in a direction intersecting with a substantially horizontally extending passage among the cylindrical surfaces of the rising passage .
[0006]
Before starting work, check the oil level of the engine. It is preferable that the time required for this inspection can be shortened.
Therefore, the oil injection passage is composed of a passage extending substantially horizontally from the crankcase and a passage rising substantially perpendicular to the passage, and the detection means is a passage where the oil injection passage rises to notify the upper limit level of the oil amount. And a second protrusion formed in the passage where the oil injection passage rises to inform the lower limit level of the oil amount , and the first protrusion is opposed to the second protrusion. It is arranged and the first and second protrusions are provided on the surface of the cylindrical surface of the rising passage that is located in a direction intersecting with the substantially horizontally extending passage so that the amount of oil can be recognized simply by looking into the oil injection passage. By making it possible, the convenience of oil inspection work will be improved.
