Description

本発明はエンジンの導風カバー構造に関し、詳細には、エンジンの温度を低下させ、エンジンの使用効果を向上させる導風カバー構造に関する。 The present invention relates to a wind guide cover structure for an engine, and more particularly, to a wind guide cover structure for reducing the temperature of the engine and improving the use effect of the engine.

一般の強制冷気式エンジン１は、図１で示されるように、主に、エンジン動力システム１、及び、冷却導風カバー２からなる。冷却導風カバー２は、エンジン動力システム１を包覆し、外界の冷却風は、エンジン１のファン１１により強制的に、ファンカバー２３の入風口２１から導風カバー２内に進入し、導風カバー２の導引により、冷却風がエンジン１に当たり、エンジン１が生成する高温は、熱交換と熱平衡作用により、導風カバー２の出風口２２から排出され、エンジン１の温度が降下する。   As shown in FIG. 1, the general forced cold air engine 1 mainly includes an engine power system 1 and a cooling air guide cover 2. The cooling air guide cover 2 covers the engine power system 1, and the external cooling air is forcibly entered by the fan 11 of the engine 1 from the air inlet 21 of the fan cover 23 into the air guide cover 2. Due to the wind cover 2 being guided, the cooling air hits the engine 1, and the high temperature generated by the engine 1 is discharged from the air outlet 22 of the wind guide cover 2 due to heat exchange and heat balance action, and the temperature of the engine 1 drops.

しかし、エンジン１の最高温度は排気ポート１２で発生し、公知の導風カバー２は、外界から導風カバー２に進入する冷却風を直接排気ポート１２に当てる構造がなく、エンジン１の排気ポート１２が高温なので、効果的に温度降下できず、エンジン１全体の温度が不均一である。また、図１、図２で示されるように、エンジン１はシリンダヘッド１３上でスパープラグ１４周辺に冷却風チャンネル１３１を設置し、冷却風チャンネル１３１の設置により、一部の冷却風が冷却風チャンネル１３１内に進入し、これにより、シリンダヘッド１３は効果的に温度低下する。しかし、公知の導風カバー２は、外界からの導風カバー２に進入する冷却風を効果的に冷却チャンネル１３１に導入する構造がない。公知の導風カバー２は、効果的にエンジン１を均衡した温度降下できず、温度不均一の状況が発生する。温度降下不均一は、エンジン１の部分の素子を変形させ、エンジン１の使用寿命を短縮する。   However, the maximum temperature of the engine 1 is generated at the exhaust port 12, and the known air guide cover 2 does not have a structure in which the cooling air entering the air guide cover 2 from the outside is directly applied to the exhaust port 12. Since 12 is hot, the temperature cannot be effectively lowered, and the temperature of the entire engine 1 is not uniform. As shown in FIGS. 1 and 2, the engine 1 is provided with a cooling air channel 131 around the spar plug 14 on the cylinder head 13, and by installing the cooling air channel 131, a part of the cooling air is cooled. Entering the channel 131, the temperature of the cylinder head 13 is effectively lowered. However, the known air guide cover 2 does not have a structure for effectively introducing the cooling air entering the air guide cover 2 from the outside into the cooling channel 131. The known wind guide cover 2 cannot effectively lower the temperature of the engine 1 in a balanced manner, resulting in a non-uniform temperature situation. The uneven temperature drop deforms the elements of the engine 1 and shortens the service life of the engine 1.

本発明の目的は、公知のエンジン導風カバーの構造の使用上の欠点を改善するエンジン導風カバー改良構造を提供することにある。 An object of the present invention is to provide an improved engine wind guide cover improvement structure that improves the disadvantages of using the known engine wind guide cover structure.

The feature is that the wind guide cover is provided with a flow guide mechanism, which is located on the engine exhaust port side of the wind guide cover and between the exhaust hole of the wind guide cover and the cooling air inlet. Due to the structural guidance, the engine fan sucks the outside cooling air of the wind guide cover and directly hits the exhaust port of the engine, thereby lowering the engine temperature and increasing the heat dissipation effect of the entire engine, Improve the usage effect.

本発明のエンジン導風カバー改良構造は、エンジンのシリンダ本体とシリンダヘッドを包覆する。主に、導風カバーは導流機構を設置し、導流機構は、導風カバーのエンジン排気ポート側に位置すると共に、冷却風出口の相反する側カバー面上に位置し、導流構造の導引により、エンジンのファンが導風カバーの外界の冷却風を吸入し、直接、エンジンのシリンダヘッドの冷却風チャンネル内に導入され、これにより、エンジンの温度を低下させ、エンジン全体の散熱効果を増加し、エンジンの使用効果を向上させる。 The engine wind guide cover improving structure of the present invention covers the cylinder body and the cylinder head of the engine. Mainly, the wind guide cover is provided with a flow guide mechanism, which is located on the engine exhaust port side of the wind guide cover and on the opposite side cover surface of the cooling air outlet. Due to the induction, the engine fan sucks the cooling air outside the wind guide cover and is directly introduced into the cooling air channel of the cylinder head of the engine, thereby reducing the temperature of the engine and the heat dissipation effect of the whole engine Increase the use effect of the engine.

本発明のエンジン導風カバー改良構造は、エンジンのシリンダ本体とシリンダヘッドを包覆する。主に、導風カバーは導流機構と第二導流機構を設置し、導流機構は、導風カバーのエンジン排気ポート側に位置すると共に、導風カバーの排気穿孔と冷却風入口の間を介し、第二導流機構は、導風カバーのエンジン排気ポート側の冷却風出口の相反する側カバー面上に位置し、導流構造と第二導流構造の導引により、エンジンのファンが導風カバーの外界の冷却風を吸入し、直接、エンジンの排気ポートに当たり、また、直接シリンダヘッドの冷却風チャンネル内に導入され、これにより、エンジンの温度を低下させ、エンジン全体の散熱効果を増加し、エンジンの使用効果を向上させる。 The engine wind guide cover improving structure of the present invention covers the cylinder body and the cylinder head of the engine. Mainly, the wind guide cover is provided with a diversion mechanism and a second diversion mechanism, which is located on the engine exhaust port side of the wind guide cover and between the exhaust perforation of the wind guide cover and the cooling air inlet. The second airflow mechanism is located on the opposite side cover surface of the cooling air outlet on the engine exhaust port side of the airflow guide cover, and the fan of the engine is guided by the induction of the current conduction structure and the second current conduction structure. Sucks the outside cooling air of the wind guide cover, directly hits the exhaust port of the engine, and is directly introduced into the cooling air channel of the cylinder head, thereby reducing the temperature of the engine and the heat dissipation effect of the whole engine Increase the use effect of the engine.

本発明により、エンジンの温度を低下させ、エンジン全体の散熱効果を増加し、エンジンの使用効果を向上させる。   According to the present invention, the temperature of the engine is lowered, the heat dissipation effect of the entire engine is increased, and the use effect of the engine is improved.

本発明のエンジン導風カバー構造は、図５、図６で示されるように、エンジン３は、クランク室３１、クランク室３１と連結するクランク軸３２、クランク室３１上に設置されるシリンダ本体３３、シリンダ本体３３中に設置されるプランジャー３４、シリンダ本体３３上に設置されたシリンダヘッド３５、及び、クランク軸３２により帯動される冷却ファン３６、からなる。シリンダ本体３３、及び、シリンダヘッド３５は、散熱面積を増加させるため、シリンダ本体３３、及び、シリンダヘッド３５上に、複数の間隔的に排列された散熱片３３１、３５１を有する。シリンダヘッド３５上に、更に、進気ポート３５２と排気ポート３５３を有する。シリンダヘッド３５の散熱片３５１は、排気ポート３５３の周縁に連接される。オイルガスが燃焼室３８に進入すると、スパープラグ３７が点火し、膨張した気体圧力は、推力を生成して、プランジャー３４を推動し、上下に往復運動する。プランジャー３４が下降する時、進気弁が開き、混合オイルガスが燃焼室３８内で燃焼し、燃焼後の廃気は、排気バルブから迅速に排出され、排気ポート３５３から排気管（図示しない）に排出される。エンジン１が作動する時、クランク軸３２が冷却ファン３６を帯動し、外界の冷却風がファンカバー４６の冷却風入口４１から導風カバー４内に進入し、導風カバー４とシリンダ本体３３、シリンダヘッド３５の間の冷却風チャンネルを通過して、冷却風がシリンダ本体３３とシリンダヘッド３５上の散熱片３３１、３５１上の熱量（高温の熱空気）を奪い、シリンダ本体３３とシリンダヘッド３５の冷却目的を達成し、エンジン動力システム３が正常な操作温度で運転し、最後に、冷却風は風出口４２から排出される。   As shown in FIGS. 5 and 6, the engine wind guide cover structure of the present invention includes a crank chamber 31, a crankshaft 32 coupled to the crank chamber 31, and a cylinder body 33 installed on the crank chamber 31. And a plunger 34 installed in the cylinder body 33, a cylinder head 35 installed on the cylinder body 33, and a cooling fan 36 driven by the crankshaft 32. The cylinder main body 33 and the cylinder head 35 have a plurality of heat dissipating pieces 331 and 351 arranged on the cylinder main body 33 and the cylinder head 35 in order to increase the heat dissipating area. On the cylinder head 35, an air advance port 352 and an exhaust port 353 are further provided. The heat dissipation piece 351 of the cylinder head 35 is connected to the periphery of the exhaust port 353. When the oil gas enters the combustion chamber 38, the spar plug 37 is ignited, and the expanded gas pressure generates a thrust, thrusts the plunger 34, and reciprocates up and down. When the plunger 34 descends, the advance valve opens, the mixed oil gas burns in the combustion chamber 38, and the waste air after combustion is quickly exhausted from the exhaust valve and is exhausted from the exhaust port 353 (not shown). ). When the engine 1 is operated, the crankshaft 32 moves the cooling fan 36, and external cooling air enters the air guide cover 4 from the cooling air inlet 41 of the fan cover 46, and the air guide cover 4 and the cylinder body 33. The cooling air passes through the cooling air channel between the cylinder heads 35, and the cooling air takes heat (high temperature hot air) on the heat dissipation pieces 331 and 351 on the cylinder main body 33 and the cylinder head 35, and the cylinder main body 33 and the cylinder head The cooling power of 35 is achieved, the engine power system 3 operates at a normal operating temperature, and finally the cooling air is discharged from the air outlet 42.

図３〜図６で示されるように、導風ファン４は、エンジン３のシリンダ本体３３とシリンダヘッド３５周外を覆い、導風ファン４上は冷却風出口４２を有し、エンジン３の進気ポート３５２側のカバー４ａを覆い、進気管（図示しない）を穿過する進気穿孔４３を設置し、エンジン３の排気ポート３５３側のカバー４ｂは、排気管（図示しない）を穿過する排気穿孔４４を設置する。導風カバー４は、エンジン３の排気ポート３５３側のカバー４ｂ上を覆い、排気穿孔４４と冷却風入口４１間を介し、傾斜面を有する導流機構５を凸設し、導流機構５の断面は三角形か弧形で、導流機構５の傾斜面は、冷却風入口４１から排気穿孔４４に向かって傾斜する。   As shown in FIGS. 3 to 6, the air guide fan 4 covers the outer periphery of the cylinder body 33 and the cylinder head 35 of the engine 3, and has a cooling air outlet 42 on the air guide fan 4. Covering the cover 4a on the side of the air port 352 and installing an air perforation 43 that penetrates the air advance pipe (not shown), the cover 4b on the exhaust port 353 side of the engine 3 penetrates the exhaust pipe (not shown). Exhaust holes 44 are installed. The air guide cover 4 covers the cover 4 b on the exhaust port 353 side of the engine 3, and the air guide mechanism 5 having an inclined surface is provided projectingly between the exhaust hole 44 and the cooling air inlet 41. The cross section is triangular or arcuate, and the inclined surface of the flow guide mechanism 5 is inclined from the cooling air inlet 41 toward the exhaust perforation 44.

本発明の実施時、図７で示されるように、導風カバー４のエンジン３の排気ポート３５３側を覆うカバー４ｂは、冷却風出口４２相反側の側カバー面４５上で、傾斜面を有する第二導流機構６を凸設し、第二導流機構６の断面は三角形か弧形で、第二導流機構６の傾斜面は冷却風入口から後に傾斜し、第二導流機構６は導流機構５に隣接し、これにより、第二導流機構６と導流機構５は隣側に対応する状態で設置される。   When the present invention is implemented, as shown in FIG. 7, the cover 4 b that covers the exhaust port 353 side of the engine 3 of the air guide cover 4 has an inclined surface on the side cover surface 45 on the opposite side of the cooling air outlet 42. The second flow guide mechanism 6 is provided in a projecting manner, the cross section of the second flow guide mechanism 6 is triangular or arc-shaped, the inclined surface of the second flow guide mechanism 6 is inclined later from the cooling air inlet, and the second flow guide mechanism 6 Is adjacent to the flow guide mechanism 5, whereby the second flow guide mechanism 6 and the flow guide mechanism 5 are installed in a state corresponding to the adjacent side.

よって、クランク軸３２が冷却ファン３６を帯動して運転するとき、外界の冷却風は、冷却風入口１から導風カバー４内に進入し、導風カバー４とシリンダ本体３３、シリンダヘッド３５間の冷却風チャンネルを通過し（矢印で示される）、一部の外界冷却風は導流機構５により導引され、直接、排気ポート３５３に当たり、エンジン３の最高温度箇所の高温が効果的に低下した後、エンジン３全体が熱平衡効果によって、エンジン３全体の温度を効果的に低下させ、その他の外界冷却風も同時に、シリンダ本体３３とシリンダヘッド３５上の散熱片３３１、３５１上の熱量を奪い、シリンダ本体３３と四厘ｄなヘッド３５を冷却する目的を達成し、エンジン動力システム３が正常な操作温度で運転し、最後に、冷却風は冷却風出口４４から排出される。   Therefore, when the crankshaft 32 operates with the cooling fan 36 moving, external cooling air enters the air guide cover 4 from the cooling air inlet 1, and the air guide cover 4, the cylinder body 33, and the cylinder head 35. And a part of the external cooling air is drawn by the flow guide mechanism 5 and directly hits the exhaust port 353, and the high temperature at the highest temperature point of the engine 3 is effectively increased. After the decrease, the entire engine 3 effectively reduces the temperature of the entire engine 3 due to the thermal equilibrium effect, and other external cooling airs simultaneously reduce the amount of heat on the heat dissipation pieces 331 and 351 on the cylinder body 33 and the cylinder head 35. The purpose of cooling the cylinder body 33 and the four-sided head 35 is achieved, and the engine power system 3 is operated at a normal operating temperature. Finally, the cooling air is supplied from the cooling air outlet 44. It is issued.

また、本発明は、導風カバー４がエンジン３の排気ポート３５３側を覆うカバー４ｂの側面４５が、傾斜面を有する第二導流機構６を凸設し、第二導流機構６の導引により、一部の冷却風が直接シリンダヘッド３５上の冷却風チャンネル３９内に導入し、これにより、エンジン３の高温箇所のシリンダヘッド３５は好ましい散熱効果を得て、エンジン３全体の温度が効果的に低下し、シリンダ本体３３とシリンダヘッド３５を冷却する目的を達成し、エンジン動力システム３が正常な操作温度で運転する。   Further, according to the present invention, the side surface 45 of the cover 4b in which the wind guide cover 4 covers the exhaust port 353 side of the engine 3 is provided so as to project the second flow guide mechanism 6 having an inclined surface. As a result, a part of the cooling air is directly introduced into the cooling air channel 39 on the cylinder head 35, whereby the cylinder head 35 at a high temperature portion of the engine 3 obtains a preferable heat dissipation effect, and the temperature of the entire engine 3 is reduced. This effectively lowers the purpose of cooling the cylinder body 33 and the cylinder head 35, and the engine power system 3 operates at a normal operating temperature.

上述のように、本発明のエンジン導風カバー構造は、導風カバー４上に設置された導流機構５と第二導流機構６により、エンジン３の冷却、及び、散熱効果を向上させ、エンジン３の散熱温度が不均一で素子が変形するのを防止する。   As described above, the engine wind guide cover structure of the present invention improves the cooling of the engine 3 and the heat dissipation effect by the flow guide mechanism 5 and the second flow guide mechanism 6 installed on the wind guide cover 4. The heat dissipation temperature of the engine 3 is not uniform and the element is prevented from being deformed.
