【発明の詳細な説明】
本発明は船外機用内燃機関の補油装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil bunkering system for an internal combustion engine for an outboard motor.
従来、一般に使用されている４サイクルの内燃機関を船
外機に搭載する場合には、その内燃機関の潤滑油だめで
あるオイルパンを設ける必要がちシ、そのオイルパンは
機関の下部、即ち船外機本体に組込むのが一番構造簡単
で一般的である。この場合そのオイルパンに潤滑油を補
給する補給口も必要ａ■、この点が従来の２サイクル機
関とは点検上大巾に異なる点である（２サイクル機関で
は一般に燃料の中に潤滑油を混合する）。Conventionally, when mounting a generally used four-stroke internal combustion engine on an outboard motor, it is necessary to install an oil pan, which is a lubricating oil reservoir for the internal combustion engine. The simplest structure and most common method is to incorporate it into the external engine body. In this case, a replenishment port for supplying lubricating oil to the oil pan is also required, which is a major difference in inspection from conventional two-stroke engines (two-stroke engines generally do not contain lubricating oil in the fuel). mix).
一般に、船外機用内燃機関はクランク軸を垂直方向に配

ばならない（機関はオイルパン内油量最大と最小の間で
使用）。そのオイルパンの補給口の位置は、そのような
船外機の特殊性を考慮した最適な位置に設けることが要
求される。Generally, an internal combustion engine for an outboard motor has a crankshaft arranged vertically, with the cylinder head side located at the rear of the outboard motor, and the crankcase located in front of it. When the outboard motor is not in use, it is necessary to tilt it up relative to the hull, and at the same time, care must be taken to ensure that only the specified amount of lubricating oil is put into the oil pan (the engine is amount used between maximum and minimum). The oil pan replenishment port is required to be located at an optimal position taking into consideration the special characteristics of the outboard motor.
そこで、本発明は上記船外機の％殊性を考慮に入れて最
適々位置にオイルパンへの補油口を設けることによシ、
その補油作業を容易にすることを目的としてなされたも
のである。Therefore, the present invention takes into consideration the particular characteristics of the outboard motor and provides an oil filler port to the oil pan at an optimal position.
This was done to make the bunkering work easier.
即ち、本発明の補油装置は４サイクルの内燃機関を搭載
した船外機において、その内燃機関のオイルパンへの補
油口をクランクケース部に設けることを特徴としたもの
である。That is, the bunkering device of the present invention is an outboard motor equipped with a four-cycle internal combustion engine, and is characterized in that a bunkering port to the oil pan of the internal combustion engine is provided in the crankcase portion.
以下図面を参照して本発明の一実施例を説明するが、図
面は本発明の実施例における船外機の側断面図であシ、
この実施例では４サイクルの２気筒のディーゼル機関を
内燃機関として装着している。An embodiment of the present invention will be described below with reference to the drawings, which are side sectional views of an outboard motor according to the embodiment of the present invention.
In this embodiment, a four-stroke, two-cylinder diesel engine is installed as the internal combustion engine.
この船外機は船体６０のトランサム６１にクランプ６２

ング２６内に内蔵されたディーゼル機関のクランク軸７
は垂直に配設され、このクランク軸７に連結されたドラ
イブシャフト６を介して船外機の下端部に設けられたプ
ロペラ３４が回転するようになっている。This outboard motor has a clamp 62 attached to the transom 61 of the hull 60.
The crankshaft 7 of the diesel engine built into the top cowling 26 of this outboard motor
is arranged vertically, and a propeller 34 provided at the lower end of the outboard motor rotates via a drive shaft 6 connected to the crankshaft 7.
そこで、このディーゼル機関のシリンダヘッド２は船外
機の後側に位置しているので、当然クランフケ−２１は
船外機の前側、即ち船体６０側に位置しておシ、またオ
イルパン８は船外機本体内に組込まれている。Therefore, since the cylinder head 2 of this diesel engine is located at the rear of the outboard motor, the crankcase 21 is naturally located at the front of the outboard motor, that is, the hull 60 side, and the oil pan 8 is located at the front of the outboard motor. It is built into the outboard motor body.
そこで、本発明ではこのオイルパン８に潤滑油を補給す
る補油口６３を船外機１の前側に位置するクランクケー
ス１に設けている。Therefore, in the present invention, a filler port 63 for supplying lubricating oil to the oil pan 8 is provided in the crankcase 1 located on the front side of the outboard motor 1.
通常４サイクル内燃機関では、オイルパン８からクラン

滑油が再びオイルパン８に戻されるような油通路または
油水が設けられているので、クランクケース１に設けだ
補油口６６に潤滑油を補給すれば、オイルパン８に当然
補給されることになる。Normally, in a four-stroke internal combustion engine, an oil passage or oil water is provided so that the lubricating oil supplied from the oil pan 8 to the crankshaft 7 provided in the crankcase 1 is returned to the oil pan 8. If lubricating oil is supplied to the oil filling port 66 provided in the case 1, the oil pan 8 will naturally be supplied with the lubricating oil.
上記のごとく補油口６６をクランクケース１に設けた本
発明の補油装置を有する船外機では、船体６０上からト
ップカウリング２６を取外すだけで船上から潤滑油の補
給が容易に行なわれることになる。In the outboard motor having the oil bunkering device of the present invention in which the oil filler port 66 is provided in the crankcase 1 as described above, lubricating oil can be easily refilled from the boat by simply removing the top cowling 26 from the hull 60. become.
また、船外機の後側のシリンダヘッド２から排出さバた
排気は、オイルパン８の後側に設けられた排気通路９経
由、排気出口３５から排出されることになるので、補油
口３６の位置としては最も適当である。In addition, the exhaust gas discharged from the cylinder head 2 on the rear side of the outboard motor is discharged from the exhaust outlet 35 via the exhaust passage 9 provided on the rear side of the oil pan 8. 36 is the most appropriate position.
一方、オイルパン８内の油面は検油棒等で点検されるが
、船外機の非使用時に矢印ＡのごＪくチルトアップした
時には適切な油面の検出ができないので、チルトアップ
時には潤滑油が補給できない方が望ましく、その点、本

内）にまで充満しておシ、チルトアップ状態で補油孔を
あけると潤滑油が流出して来るし、又開孔方向が上下で
はないので、補油できないという利点がある。On the other hand, the oil level in the oil pan 8 is checked with a dipstick, etc., but when the outboard motor is not in use and the outboard motor is tilted up as indicated by arrow A, the oil level cannot be detected properly. It is preferable that lubricating oil cannot be replenished, and in this respect, if the oil filler port 36 is provided at the position as in the present invention, the oil in the oil pan will fill up to the oil filler hole (inside the crankcase) when tilting up. However, if the oil filler hole is opened in the tilted-up state, lubricating oil will flow out, and since the opening direction is not up or down, there is an advantage that oil filling is not possible.

。Therefore, in an outboard motor to which the present invention is applied, the oil pan can be easily refueled from the outside of the boat, and it is possible to ensure that the amount of lubricating oil in the oil pan is at an appropriate level (tilt-up If the lubricating oil can be replenished even at times, the oil level indicated by the oil check will be incorrect and the engine will have to be operated with a different amount of oil (this can lead to engine seizure, etc.). It is possible to maintain an appropriate oil level in the reeds and oil pan.
