2 9 7 7 1 1號公報 【發明内容】 (發明所欲解決之問題） 在習知具備燃料喷射裝置模組的車輛中，因為將該模組 配設於引擎與燃料槽中間，因此在引擎上所安裝的喷嘴、 與燃料喷射裝置模組的燃料泵之間，便需要配設高單價的 高壓燃料導管，其成為成本降低的阻礙。 本發明乃有鑒於上述情事，其目的在於使喷嘴與燃料泵 間的高壓燃料導管可廢棄化，以達上述燃料喷射裝置模組 成本降低之功效。 (解決問題之手段） 緣是，為達上述目的，本發明的第1特徵係在電動馬達 中，將經其輸出軸驅動而將從燃料槽所導入的燃料予以昇 壓且壓送至喷嘴的燃料泵，以及調整從此燃料泵壓送給喷 6 31W發明說明書(補件)/92-11/92124315 200407500 嘴之燃料壓力的喷射壓力調節器予以一體結合的燃料喷射 裝置模組，其中，在結合於燃料泵上的模組本體上，一體 形成保持著噴嘴的噴嘴夾持座，而且在此模組本體中，形 成將燃料泵、噴射壓力調節器及喷嘴相互間予以連通的通 路。 依照此第1特徵，則模組本體便形成兼具習知連接燃料 泵與噴嘴間的高壓燃料導管，所以，可省略高單價的高壓 燃料導管及其配管作業，可達燃料喷射裝置模組成本減少 之目的。 再者，除第1特徵之外，本發明之第2特徵為在模組本 體中，設有隨車輛翻倒，將燃料泵與噴嘴間之燃料通路予 以阻斷的翻倒阻斷閥。 依照此第2特徵，則在車輛翻倒時，不僅引擎運轉可自 動地迅速停止，而且即便喷嘴脫離引擎、或喷嘴夾持座脫 離喷嘴的情況之下，仍可利用翻倒阻斷閥防止燃料流出於 夕卜面。 再者，除第1或第2特徵之外，本發明之第3特徵為在 燃料泵中，一體結合著將從燃料槽導入之燃料予以過濾的 燃料滤清器。 依照第3特徵，則燃料濾清器便形成燃料喷射裝置模組 的構成要件，可廢棄燃料濾清器與燃料泵間的配管，而且 因為燃料濾·清器'屬於將燃料豕上游的燃料予以過滤者’因 此僅要低價的低壓式者便足夠，可獲得燃料喷射裝置模組 降低成本之效果。 7 312/發明說明書(補件)/92-11 /92124315 200407500 【實施方式】 針對本發明實施形態，根據圖式所示之本發明較佳實施 例進行說明。 圖1所示係具備本發明之燃料噴射裝置模組的機車主要 部分側視圖；圖2所示係上述燃料喷射裝置模組的放大側 視圖；圖3所示係該燃料喷射裝置模組的放大平面圖；圖

相關此燃料喷射裝置模組M F，參照圖2〜圖7進行說明。 8 312/發明說明書(補件)/92-11 /92124315 200407500 燃料喷射裝置模組 M F係具備有：電動馬達 1 0、燃料泵 1 1、燃料濾清器1 2、喷嘴1 3、喷射壓力調節器1 4、殘壓 保持閥1 5、及翻倒阻斷閥1 6。 如圖4與圖5所示，電動馬達10係無刷式（brushless)， 其馬達殼體1 7内部利用與馬達殼體1 7 —體的圓筒狀隔間 壁1 7 a，防水地劃分出外周側的定子室1 8、與内周側的轉 子室19，在定子室18中收容著定子線圈20，在轉子室19 中收容著外圍固設有永久磁鐵2 2的轉子2 1。 在圓筒狀隔間壁1 7 a中，一體形成配置於轉子2 1中空 部内的軸承套筒2 3，並在其上隔著軸承構件2 4旋轉自如 地支撐著轉子21之輸出軸21a。 在馬達殼體 1 7的一端面上結合著燃料泵 1 1的泵殼體 2 6。泵殼體2 6係由内殼體2 6 a，及隔著密封構件2 7嵌合 於内殼體2 6 a外周、並在與内殼體2 6 a之間劃分出泵室2 8 的外殼體2 6 b所構成，外殼體2 6 b係利用複數個螺栓29 固接於馬達殼體1 7上，以形成與馬達殼體1 7挾持著内殼 體2 6 a的狀態。電動馬達1 0之輸出軸2 1 a係前端部延伸至 上述泵室28，並在該室28處於其前端部上連結著泵轉子 3 0。依此方式構成的燃料泵1 1乃屬於摩擦式（W e s c 〇 t y p e )。 在外殼體 2 6 b外側面上，一體地突設著：將燃料吸入泵 室2 8中的吸入管3 1、從泵室2 8中送出燃料的送出管3 2、 以及從泵室2 8中排放出蒸氣的蒸氣排放管3 3。即，蒸氣 排放管3 3係透過小孔3 4連結於較容易排放出泵室2 8内蒸 氣之處。 9 312/發明說明書(補件)/92-11 /92124315 200407500 再者，在吸入管3 1中一體形成濾清器底座3 5，利用此 濾清器底座3 5、連結於其上的濾清器箱3 6、及收容於此濾 清器箱3 6内的濾清器元件3 7，藉以構成上述燃料濾清器 1 2，並在一體地形成於濾清器箱 3 6上的燃料導入連接管 3 8中，連接著從上述燃料槽T延伸出的燃料供應管3 9，使 燃料槽T内的燃料利用重力而流下至燃料濾清器1 2。 如圖7所示，連接於上述送出管3 2與蒸氣排放管3 3上 的模組本體4 0，係利用螺栓4 2固接於從馬達殼體1 7 —側 面伸出的托架4 1。在此模組本體4 0中設有·.上述喷嘴1 3、 喷射壓力調節器1 4、殘壓保持閥1 5及翻倒阻斷閥1 6。殘 壓保持閥1 5乃由周知的逆止閥構成。 在翻倒阻斷閥1 6的模組本體4 0上所形成的入口孔4 4， 係連通於上述送出管3 2。此外，翻倒阻斷閥1 6的出口孔 4 5亦是連通於模組本體4 0上所形成的喷射燃料通路4 6， 在此喷射燃料通路4 6上並排連接著喷嘴1 3與喷射壓力調 節器1 4，同時在較該等更上游的喷射燃料通路4 6上，介 設著防止燃料朝送出管3 2側逆流的殘壓保持閥1 5。 在模組本體4 0的一側，一體形成保持著噴嘴1 3的喷嘴 夾持座4 7。此喷嘴夾持座4 7係具有對應著上述吸氣管5 之支撐法蘭5 a的安裝法蘭4 7 a，當將此安裝法蘭4 7 a利用 螺栓4 9接合於支撐法蘭5 a上之時，喷嘴1 3的燃料喷射部 便將***於支撐法蘭5 a上所開口的噴嘴安裝孔5 0中並朝 向進氣口 4。 如圖4所示，喷射壓力調節器1 4係由下述構件所形成： 10 312/發明說明書(補件)/92-11 /92124315 200407500 具有緊鄰噴射燃料通路4 6的閥座6 2且與模組本體4 0 形成的調節器殼體61、收容於此調節器殼體6 1中並 座6 2相對向的閥構件6 3、對此閥構件6 3賦予朝座接 座6 2之方向彈力的調壓彈簧6 4、以及螺合於調節器 6 1上以調整調壓彈簧6 4設定荷重的調整螺絲6 5 ;調 殼體6 1内係經由模組本體4 0内的燃料送返通路6 6而 於與模組本體4 0呈一體的燃料送返連接管6 7。若燃 1 1的送出壓力（即噴射燃料通路4 6的壓力）達規定值 的話，閥構件6 3便離開閥座6 2並將多餘燃料排放出 節器殼體6 1中，藉此將噴射燃料通路4 6之壓力保持 定值。被排放出於調節器殼體6 1中的多餘燃料便朝燃 返通路6 6前進。 上述蒸氣排放管3 3在燃料送返通路6 6之中途處開 在燃料送返連接管6 7上連接於到達燃料槽Τ的燃料送 68 〇 再度參照圖1，在上述油門本體6之一側配設著電 制單元7 0。此電子控制單元7 0係根據所輸入的引擎 數N e、引擎溫度（如潤滑油溫度）T e、油門本體6之油 度Th、曲柄位置Cp等信號，控制著喷嘴1 3、電動馬達 及點火線圈（未圖示）等的動作。 所以，在引擎E之運轉中，燃料槽T内的燃料便從 供應管3 9流下並到達燃料喷射裝置模組MF的燃料導 接管3 8，然後流入於燃料濾清器1 2的濾清器箱3 6中 濾清器元件3 7進行過濾。如此經過濾的燃料便被吸入 312/發明說明書(補件)/92-11 /92124315 一體 與閥 於閥 殼體 節器 連通 料泵 以上 於調 於規 料送 口 ° 返管 子控 旋轉 門開 10、 燃料 入連 ，由 於燃 11 200407500 料泵11的泵室28中，並利用泵轉子30的旋轉而昇壓，並 從送出管3 2壓送入噴射燃料通路4 6。在此期間於燃料泵 1 1之泵室2 8内所產生的蒸氣將被排放出於蒸氣排放管3 3 中，並到達燃料送返通路6 6。 被壓送至喷射燃料通路 46的高壓燃料，則經由翻倒阻 斷閥1 6與殘壓保持閥1 5而供應給噴嘴1 3，再從喷嘴1 3 朝進氣口 4喷射出。 在此期間，如上述從噴射燃料通路 4 6 通過喷射壓力調 節器 1 4 的多餘燃料，因為將以較高速通過燃料送返通路 6 6，並在中途利用喷出效應引進來自蒸氣排放管 3 3的蒸 氣，因此可促進蒸氣的排放。依此若從燃料泵 1 1排除蒸 氣，便可對喷嘴1 3供應未含蒸氣之良好狀態的燃料。 從蒸氣排放管3 3通過燃料送返通路6 6而出的蒸氣，將 與多榦燃料一齊通過燃料送返管6 8而返回燃料槽T中，並 在燃料槽T内進行氣液分離。 若隨引擎E的運轉停止，而停止電動馬達1 0動作的話， 燃料泵1 1便停止燃料送出，而因為喷射燃料通路4 6的殘 壓保持閥1 5將自動地阻斷，阻止在該喷射燃料通路4 6中 燃料從噴嘴1 3側逆流於燃料泵1 1側，因此在喷嘴1 3入口 側可持續保持著既定壓力的燃料，所以，即便引擎E再開 始動作，喷嘴1 3仍可馬上喷射燃料，可提高始動性。 其次，利用圖8針對上述翻倒阻斷閥1 6進行說明。 翻倒阻斷閥1 6係如圖8 ( N )所示，具備有：在機車Μ正立 狀態下，採取朝斜左上方向姿態而形成於模組本體4 0上的 12 312/發明說明書(補件)/92-11/92124315 200407500 圓筒狀第1閥室5 5，以及採取其相反地朝斜右上方向姿態 而形成於模組本體4 0上的圓筒狀第2閥室5 6 ;第1閥室 5 5上端連接於第2閥室5 6的中間部。在第1與第2閥室 55，56的各上端分別形成第1與第2閥座55a，56a，在第1 閥座5 5 a下端開設連接於上述燃料泵1 1之送出管3 2的入 口孔4 4，並在第2閥座5 6 a的上端開設上述出口孔4 5。在 第1與第2閥室5 5，5 6中，收容著分別可座接於第1與第 2閥座5 5 a，5 6 a上的球狀閥體5 7，5 8，而第1與第2閥室 5 5，5 6的各下端則利用螺栓5 9，6 0而閉塞。 所以，在機車Μ正立狀態下，如圖8 (N)所示，第1與第 2閥體5 7，5 8將因本身重量而離開第1與第2閥座5 5 a，5 6 a 並停留於栓體5 9，6 0上。因而入口孔4 4與出口孔4 5間將 被導通，並允許從燃料泵1 1朝噴嘴1 3進行燃料供應。 但是，萬一當機車Μ朝左方或右方翻倒的情況時，便如 圖8 ( L )或（R )所示，隨第1閥室5 5或第2閥室5 6翻倒呈 略水平，第1閥體5 7或第2閥體5 8將隨此慣性力而座接 於第1閥座5 5 a或第2閥座5 6 a上，任何情況下均會阻斷 入口孔44與出口孔45間。依此的話，若第1閥體57或第 2閥體5 8 —經座接於第1閥座5 5 a或第2閥座5 6 a上的話， 此座接狀態便將經由入口孔4 4側的燃料壓力而保持著。所 以，即便在隨機車Μ的翻倒而使喷嘴1 3脫離引擎E，或使 喷嘴夾持座4 7脫離喷嘴1 3的情況下，均可利用翻倒阻斷 閥1 6防止從喷射燃料通路4 6流出燃料。 但是，燃料喷射裝置模組 MF係因為在一體連結於電動 13 312/發明說明書(補件)/92-11 /92124315 200407500 馬達1 0上的燃料泵1 1之外殼體2 6

高壓燃料導管之用，故而可省略高單價的高壓燃料導管 其配管作業，可達大幅降低燃料喷射裝置模組MF成本之 效。 而且，因為在模組本體4 0中組合著翻倒阻斷閥1 6， 此當機車Μ翻倒時，可自動地迅速停止引擎E之運轉， 即便在喷嘴1 3脫離引擎Ε，或喷嘴夾持座4 7脫離喷嘴 的情況下，仍可利用翻倒阻斷閥1 6防止燃料流出於外面 再者，在燃料泵1 1中，因為一體連結著從燃料槽Τ 入並過濾燃料的燃料濾清器1 2，因而燃料濾清器1 2便 為燃料喷射裝置模組 MF的構成要件，可廢棄燃料濾清 1 2與燃料泵1 1間的配管，而且因為燃料濾清器1 2屬於 燃料泵1 1上游的燃料予以過濾者，因此僅要低價的低壓 便足夠，可獲得燃料噴射裝置模組降低成本之效果。 本發明並不僅限於上述實施例，在不脫離其主旨範疇 前提下，可進行各種設計變更。 (發明效果） 如上述，若依照本發明之第1特徵，因為係在電動馬

The connection pipe 38 is connected to the fuel supply pipe 39 extending from the fuel tank T, and the fuel in the fuel tank T flows down to the fuel filter 12 using gravity. As shown in FIG. 7, the module body 40 connected to the above-mentioned delivery pipe 3 2 and the steam discharge pipe 33 is fixed to the bracket 4 1 protruding from the side of the motor case 17 with bolts 4 2. . The module body 40 is provided with the above-mentioned nozzle 1 3, the injection pressure regulator 14, the residual pressure holding valve 15 and the overturn blocking valve 16. The residual pressure holding valve 15 is constituted by a well-known check valve. The inlet hole 44 formed in the module body 40 of the overturn blocking valve 16 is connected to the above-mentioned delivery pipe 32. In addition, the exit hole 45 of the overturn blocking valve 16 is also connected to the injection fuel passage 46 formed on the module body 40, and the injection fuel passage 46 is connected to the nozzle 13 and the injection pressure side by side. At the same time, the regulator 14 is provided with a residual pressure holding valve 15 for preventing the fuel from flowing backward toward the delivery pipe 32 side in the injection fuel passage 46 more upstream than these. On one side of the module body 40, a nozzle holder 47 holding the nozzles 13 is integrally formed. The nozzle holder 4 7 has a mounting flange 4 7 a corresponding to the support flange 5 a of the suction pipe 5 described above. When the mounting flange 4 7 a is joined to the support flange 5 a by a bolt 4 9 At this time, the fuel injection portion of the nozzle 13 will be inserted into the nozzle mounting hole 50 opened in the support flange 5 a and face the air inlet 4. As shown in FIG. 4, the injection pressure regulator 14 is formed of the following components: 10 312 / Invention Specification (Supplement) / 92-11 / 92124315 200407500 has a valve seat 6 2 adjacent to the injection fuel passage 4 6 and A regulator housing 61 formed by the module body 40, a valve seat 6 opposite to the seat 6 2 housed in the regulator housing 61, 3, and the valve member 6 3 is provided in a direction toward the seat socket 6 2 An elastic pressure adjusting spring 6 4 and an adjusting screw 6 5 screwed on the adjuster 6 1 to adjust the pressure adjusting spring 6 4 to set the load; the adjusting case 6 1 is returned by the fuel in the module body 40. The passage 66 is a fuel return connection pipe 67 integrated with the module body 40. If the delivery pressure of the fuel 11 (that is, the pressure of the injection fuel passage 46) reaches a predetermined value, the valve member 6 3 leaves the valve seat 62 and discharges excess fuel out of the joint housing 61 to thereby inject the fuel. The pressure of the fuel passage 46 is kept constant. The excess fuel discharged from the regulator case 61 is advanced toward the flashback path 66. The above-mentioned vapor exhaust pipe 33 is opened in the middle of the fuel return path 66, and the fuel return connection pipe 67 is connected to the fuel delivery 68 that reaches the fuel tank T. Referring to FIG. 1 again, on one side of the throttle body 6 Equipped with electric unit 70. This electronic control unit 70 controls the nozzle 1 3, the electric motor and the signal based on the inputted number of engine N e, engine temperature (such as lubricating oil temperature) T e, oil degree Th of throttle body 6 and crank position Cp. The operation of an ignition coil (not shown). Therefore, during the operation of the engine E, the fuel in the fuel tank T flows down from the supply pipe 39 and reaches the fuel guide pipe 38 of the fuel injection device module MF, and then flows into the filter of the fuel filter 12 The filter elements 37 in the tank 36 are filtered. In this way, the filtered fuel is sucked into the 312 / Instruction Manual (Supplement) / 92-11 / 92124315, which is integrally connected with the valve and the valve housing, and the material pump is adjusted above the gauge feed port. The return pipe control revolving door opens 10 Since the fuel is fed into the pump chamber 28 of the 200407500 feed pump 11, the pressure is increased by the rotation of the pump rotor 30, and the pressure is fed from the delivery pipe 32 to the injection fuel passage 46. During this period, the vapor generated in the pump chamber 2 8 of the fuel pump 11 will be discharged out of the vapor discharge pipe 3 3 and reach the fuel return path 6 6. The high-pressure fuel sent to the injection fuel passage 46 is supplied to the nozzle 13 through the overturning blocking valve 16 and the residual pressure maintaining valve 15 and is then injected from the nozzle 13 to the air inlet 4. During this period, the excess fuel passing from the injection fuel passage 4 6 through the injection pressure regulator 1 4 will pass through the fuel return passage 6 6 at a relatively high speed, and the injection effect will be introduced from the vapor discharge pipe 3 3 midway. The vapor can therefore promote the emission of vapor. Accordingly, if the steam is removed from the fuel pump 11, the nozzle 13 can be supplied with fuel in a good condition that does not contain steam. The vapor exiting from the vapor exhaust pipe 33 through the fuel return path 66 is returned to the fuel tank T through the fuel return pipe 6 8 together with the multi-dried fuel, and is separated into gas and liquid in the fuel tank T. If the operation of the engine E is stopped and the electric motor 10 is stopped, the fuel pump 11 will stop the fuel delivery, and the residual pressure maintaining valve 15 of the fuel injection path 46 will be automatically blocked to prevent the injection. In the fuel passage 46, fuel flows from the nozzle 13 side to the fuel pump 11 side. Therefore, the fuel at a predetermined pressure can be continuously maintained at the inlet side of the nozzle 13. Therefore, even if the engine E restarts, the nozzle 13 can still be immediately Fuel injection improves startability. Next, the above-mentioned overturn blocking valve 16 will be described with reference to FIG. 8. As shown in FIG. 8 (N), the overturn shut-off valve 16 includes: 12 312 / Invention specification (formed on the module body 40 that adopts an oblique upper left direction posture when the locomotive M is in the upright state) Supplement) / 92-11 / 92124315 200407500 cylindrical first valve chamber 55, and a cylindrical second valve chamber 5 6 formed on the module body 40 in the opposite attitude toward the upper right diagonal direction; An upper end of the first valve chamber 55 is connected to an intermediate portion of the second valve chamber 56. First and second valve seats 55a, 56a are formed at the upper ends of the first and second valve chambers 55 and 56, respectively. At the lower end of the first valve seat 5 5a, an outlet pipe 3 2 connected to the fuel pump 11 is opened. An inlet hole 4 4 is formed at the upper end of the second valve seat 5 6 a. The first and second valve chambers 5 5 and 5 6 contain ball valve bodies 5 7 and 5 8 which can be seated on the first and second valve seats 5 5 a and 5 6 a, respectively. The lower ends of the first and second valve chambers 5 5 and 5 6 are closed with bolts 5 9 and 60. Therefore, in the upright state of the locomotive M, as shown in FIG. 8 (N), the first and second valve bodies 5 7, 5 8 will leave the first and second valve seats 5 5 a, 5 6 due to their own weight. a and stay on the suppository body 59,60. Therefore, the inlet hole 44 and the outlet hole 45 will be electrically connected, and allow the fuel supply from the fuel pump 11 to the nozzle 13. However, if the locomotive M is overturned to the left or right, as shown in FIG. 8 (L) or (R), it will appear as the first valve chamber 5 5 or the second valve chamber 5 6 overturns. Slightly horizontal, the first valve body 5 7 or the second valve body 5 8 will be seated on the first valve seat 5 5 a or the second valve seat 5 6 a with this inertial force, and the inlet will be blocked under any circumstances Between the hole 44 and the exit hole 45. According to this, if the first valve body 57 or the second valve body 5 8 is connected to the first valve seat 5 5 a or the second valve seat 5 6 a via the seat, the seat connection state will pass through the inlet hole 4 The fuel pressure on the 4 sides is maintained. Therefore, even if the nozzle 13 is detached from the engine E or the nozzle holder 4 7 is detached from the nozzle 13 by the overturning of the random vehicle M, the overturn blocking valve 16 can be used to prevent the fuel injection path. 4 6 out of fuel. However, the fuel injection device module MF is integrally connected to the outer casing 2 6 b of the fuel pump 1 1 on the electric motor 13 312 / Invention Manual (Supplement) / 92-11 / 92124315 200407500 on the motor 10 Hold the mold body 40, and in this module body 40, a residual pressure holding valve 15, an injection pressure regulator 14 and an overturn blocking valve 16 are provided, and a nozzle holder holding the nozzle 1 3 is integrally formed. The seat 4 7 is formed in the module body 40 to form a fuel injection passage 4 6 which communicates with each of the injection 1 3, the residual pressure holding valve 15, the injection pressure regulator 14, and the overturn blocking valve. Therefore, the special module body 40 will form a high-pressure fuel conduit that is conventionally used to connect the fuel pump 11 and the nozzle 13. Therefore, the piping operation of the high-pressure fuel conduit of a high unit price can be omitted, and the fuel injection device can be greatly reduced. Efficiency of module MF cost. Moreover, because the overturn blocking valve 16 is combined in the module body 40, when the locomotive M is overturned, the operation of the engine E can be quickly and automatically stopped, even when the nozzle 13 is detached from the engine E or the nozzle clamp. In the case where the holder 4 7 is detached from the nozzle, the overturn blocking valve 16 can still be used to prevent the fuel from flowing outside. In the fuel pump 11, the fuel filter that is connected to and filters the fuel from the fuel tank T is integrally connected. The fuel filter 12 is a constituent element of the fuel injection device module MF, and the piping between the fuel filter 12 and the fuel pump 11 can be discarded, and because the fuel filter 12 is a fuel The fuel upstream of the pump 11 is filtered, so only low-cost low pressure is sufficient, and the effect of reducing the cost of the fuel injection device module can be obtained. The present invention is not limited to the above embodiments, and various design changes can be made without departing from the scope of the gist thereof. (Effects of the Invention) As described above, according to the first feature of the present invention, it is caused by the electric horse 312 / Invention Manual (Supplement) / 92-11 / 92124315. The nozzles of the 16 series are related to the work factor and 13% are formed. In the device type 14 200407500, a fuel pump that is driven by its output shaft to boost the pressure of the fuel introduced from the fuel tank and feed it to the nozzle, and injection that adjusts the fuel pressure that is fed from the fuel pump to the nozzle A fuel injection device module in which a pressure regulator is integrated, wherein a nozzle holder for holding a nozzle is integrally formed on a module body coupled to a fuel pump, and a fuel pump is formed in the module body. The injection pressure regulator and the nozzle communicate with each other. Therefore, the module body forms a high-pressure fuel conduit that is conventionally connected between the fuel pump and the nozzle. Therefore, the high-price fuel conduit and its piping operation can be omitted. It can achieve the purpose of reducing the cost of the fuel injection device module. In addition, according to the second feature of the present invention, in addition to the first feature, the module body is provided with an overturning block that blocks the fuel passage between the fuel pump and the nozzle with the vehicle overturning. The valve prevents the engine from automatically and quickly stopping when the vehicle is overturned, and prevents the fuel from flowing out even when the nozzle is detached from the engine or the nozzle holder is detached from the nozzle. Furthermore, according to the third feature of the present invention, in addition to the first or second feature, the fuel pump is integrally integrated with a fuel filter that filters the fuel introduced from the fuel tank, so the fuel is filtered. The fuel filter forms the constituent elements of the fuel injection device module, which can dispose of the piping between the fuel filter and the fuel pump, and because the fuel filter filters the fuel upstream of the fuel pump, only a low-cost low-pressure type is required. This is enough to obtain the cost reduction effect of the fuel injection device module.
