この発明は、ゴルフカーなどの小型車両のエンジン装置
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an engine device for a small vehicle such as a golf car.
車体後部にエンジンルームを設けて小型のエンジンを搭

特開昭６１−２１８７１０号公報参照。There are small vehicles such as golf cars that have an engine compartment in the rear of the vehicle body and are equipped with a small engine, and the engine drives the two rear wheels. In this type of small vehicle, the engine compartment is covered with a frame cover, so the engine is cooled by forced air cooling. for example,
See Japanese Patent Application Laid-Open No. 61-218710.

ジンを始動するのが困難になる不都合がある。While the engine is running, a cooling fan attached to the crankshaft forces cooling air into the cylinders to cool them. However, if you stop the engine while it is running, such as during the summer when the outside temperature is high, the fuel hose near the cylinder will be heated by the residual heat from the engine heat and muffler heat generated during operation, causing paper lock. There is an inconvenience that it becomes difficult to start the engine again.

容易にできる小型車両のエンジン装置を得ることを目的
とする。In view of these points, this invention arranges the cylinder and cylinder head of a forced air-cooled engine so as to be inclined to the rear, and connects a fuel hose from the front side of the crankcase to the upper side of the fan cover to remove residual heat after the engine is stopped. To provide an engine device for a small vehicle, which can be easily restarted without causing paper lock.

うにしたことにある。In order to achieve the above object, the engine device for a small vehicle of the present invention is configured such that the engine mounted in the engine room at the rear of the vehicle body drives the rear two wheels, and the engine has a cylinder and a cylinder head tilted rearward. A cooling fan connected to the end of the crankshaft provides forced cooling, and a fuel hose is routed from the front of the crankcase through the upper side of the fan cover to the carburetor connected to the side of the cylinder head.

パーロックの発生を防止できて再始動が容易にできる。While the vehicle is running, the cooling fan rotates to forcefully cool the cylinder and cylinder head. On the other hand, the wind received while driving flows into the engine compartment from the front lower part,
It gradually flows from the windward side to the crankcase, fan cover, and cylinder where the amount of heat generated is higher, lowering the temperature of the fuel hose. Also, when operation is stopped, residual heat in the cylinder and cylinder head is greatest. Since the fuel hose is installed away from this part, it receives less residual heat, prevents the occurrence of paper lock, and facilitates restarting.
以下、本発明の実施例を図面によって説明する。 Embodiments of the present invention will be described below with reference to the drawings.
小型の車両は、車体１の後部をフレームカバ２で覆って

。エンジン５は、エンジンルーム３の前部に搭載する。In a small vehicle, an engine compartment 3 is formed by covering the rear part of a vehicle body 1 with a frame cover 2. The frame cover 2 has a passenger seat 4 attached to the front part and is slightly lowered. The engine 5 is mounted in the front part of the engine room 3.

、マフラ１８をエンジンルーム３の後上部に配置する。The engine 5 is connected to one end of a crankshaft 6 to a continuously variable belt transmission 7, and further drives two rear wheels 9 via a transmission 8. The engine 5 has a cylinder 11 and a cylinder head 12 tilted rearward from a crankcase 10, and a cylinder cover 1.
Cover with 3. A cooling fan 14 is attached to the end of the crankshaft 6 and covered with a fan cover 15, and the fan cover 15 is connected to the cylinder cover 13. The cylinder head 12 has an intake port facing the side, and a carburetor 16 is connected to the side. Further, an exhaust pipe 17 is connected to the cylinder head 12, and a muffler 18 is arranged at the rear upper part of the engine room 3.

ルーム３内を流入して、後側に向けて流れる。An air cleaner 19 disposed on the side of the engine 5 is connected to the carburetor 16. A fuel tank 20 and a battery 21 are located on both sides of the engine 5 at the front of the engine room 3.
It is arranged. The fuel hose 22 passes from the fuel tank 20 to the front side of the crankcase 0, and further passes above the fan cover 15 to connect to the carburetor 16. Running,
The rotation of the crankshaft 6 causes the cooling fan 14 to move to the cylinder 11.
Cooling air is then sent to the cylinder head 12 to cool it down, and the wind received from the front lower part of the engine room 3 while driving flows into the engine room 3 and flows toward the rear side.

できる。As explained above, since the present invention is configured as described above, while the cylinder and cylinder head are forcibly cooled by the cooling fan during driving, the wind received during driving flows in from the front lower part of the engine room. This wind flows from the front to the rear, and as it moves toward the rear, it hits the cylinder, cylinder head, muffler, and other parts that produce a large amount of heat, increasing the temperature. The temperature in front of the cylinder is low, which prevents the temperature of the fuel hose from rising. When the engine is stopped, the temperature of the cylinder, cylinder head, and muffler is particularly high, and residual heat is generated. However, by placing the fuel hose away from these parts, the temperature of the fuel hose can be prevented from rising, and vapor lock can occur. restart is easy.
