Description of the Invention: TECHNICAL FIELD The present invention relates to a cylinder head arrangement mechanism, and more particularly to an in-cylinder injection cylinder head arrangement mechanism. [Prior Art] As shown in FIG. 1, a conventional in-cylinder injection cylinder head arrangement mechanism for a locomotive injection engine is configured to mount a high pressure nozzle u at a distance from a cylinder head 12 above the cylinder head. And extending the two into a combustion chamber 14 formed between the cylinder head 13 and a cylinder 16, the cylinder head 13 having an intake passage and an exhaust passage (not shown). It is used to introduce and discharge air into the combustion t 14 R. The cylinder 16 is provided with a piston 15 for reciprocating motion, and it is to be noted that the top surface of the piston 15 is formed with a guide groove 151 for guiding. Since the arrangement of the high-pressure nozzle 11 belongs to, the direct injection in the cylinder, the fuel injection arrangement, and the distance between the spark plug 12 and the high-pressure nozzle u is not large, when the high-pressure nozzle u When fuel is injected into the combustion chamber 14, the fuel is likely to be completely mixed (air atomization) in the air which has not been input to the armor A which is burned to 14 by the intake port (not shown). That is, it is ignited by the spark plug 12, and the combustion is incomplete in the combustion chamber 14. In addition to the problem of incomplete combustion, such as the reduction of engine output efficiency and high fuel consumption, it will also produce high-polluting emissions. 'In today’s environmental protection and energy-consciousness, it is quite serious. problem. In order to solve the above problem, it is common practice to provide a guide groove 151 on the top surface of the piston 15 200928082. When the piston 15 is in contact with the injected fuel, the direction of the injected fuel will change accordingly. In a vortex flow direction, the injected fuel can be more completely mixed with the input air before being ignited by the spark plug 12, but when the engine is being actuated, the combustion chamber 14 is in a state of high temperature and high pressure. And the top surface of the piston 15 is due to the flow guiding groove
❹ 151的關係，在結構上是呈一不規則的型態，而不規則之型 態在結構強度上相對較差’因此，該活塞15之頂面，尤其 是在導流槽151之部分很可能因長期處於高壓及高溫的環 境下而損壞，進而降低該活塞15的使用壽命，再者，具有 該導流槽151的活塞15由於構造上較為複雜，在生產製造 上也相對地較為困難並提高該活塞15的製造成本。 另外要注意的是，該火星塞12是直接螺接於該汽缸頭 13上，由於該火星塞12之自身之結構型態以及該汽缸頭 13週遭空間狹小與可能因油污或其他因素等造成視線不佳 ，令該火星塞12在拆裝時需要特殊工具(例如一套筒扳手) ’且有-定程度的施工難度’進而使更換或檢修該火星塞 12時更顯得困難。 【發明内容】 代於一徑便签」只田在不 ==槽的情況下’即可使嘴入燃料充分霧化，進而 ，動力性能及減少排污的缸时射缸頭配置機構。 鱼二’本發明之缸内嘴射缸頭配置機構，是設於—機 車之喷射式引擎的汽缸上 疋"^機 之一侧連接右X几缸内具有一活塞，該汽缸 有—鏈條室’該喷射Μ擎機車之缸内噴射配 6 200928082 置機構包含：一汽缸頭、一高壓喷嘴單元，及一火星塞單 元。 該汽虹頭是設置於該汽缸上，並與該汽缸相配合地界 疋出一燃燒室，該汽缸頭具有相間隔地與該燃燒室相連通 的一進氣道與一排氣道、一鄰近該汽缸之鏈條室並與該燃 燒至相連通的第一接合部，及一遠離該鏈條室並與該燃燒 室相連通的第二接合部。 該高屋噴嘴單元是藉由該汽缸頭之第二接合部與該汽 缸頭相連接，並用於將高壓燃料喷入該燃燒室内。 '•亥火星塞單元具有一藉由該汽缸頭之第一接合部地連 接於該汽缸頭上並貫穿該汽缸之鏈條室的襯套，以及一穿 設於該襯套内，並伸入該燃燒室内的火星塞，該火星塞是 藉由該汽缸頭之第一接合部鎖付於該汽缸頭上，並藉由該 火星塞與該襯套的連結關係同時將該襯套迫緊並同樣定位 於該汽缸頭上。 本發明之功效在於利用該火星塞單元穿伸過該鏈條室 的設置方式，使該火星塞單元在設置時能充分利用該汽缸 頭之空間並拉大與1¾高壓噴嘴單元之間的距離，進而使由 該冋壓噴嘴單TG所喷入該燃燒室内之燃料在被該火星塞單 元點燃之前能有更多的空間與時間來與空氣混合，且此種 鉦内喷油及點火之配置方式可令該活塞不需具有如習知般 的導流槽即可使該燃燒室内的燃料充分霧化，進而使該活 塞不會因該導流槽而犧牲其使用壽命及製造成本，而該火 星塞是配合-襯套來與該汽紅頭進行連接，進而使拆卸或 7 200928082 組裝時更為便利。 【實施方式】 有關本發明之前述及其他技術内容、特點與功效，在 以下配合參考圖式之二個較佳實施例的詳細說明中將可 清楚的呈現。 在本發明被詳細描述之前，要注意的是，在以下的說 明中’類似的元件是以相同的編號來表示。 ❹The relationship of ❹ 151 is structurally an irregular pattern, and the irregular pattern is relatively inferior in structural strength. Therefore, the top surface of the piston 15, especially in the portion of the flow guiding groove 151, is likely Damaged by the environment of high pressure and high temperature for a long period of time, thereby reducing the service life of the piston 15. Further, the piston 15 having the guide groove 151 is relatively complicated in construction and relatively difficult to manufacture and improve. The manufacturing cost of the piston 15. In addition, it should be noted that the spark plug 12 is directly screwed to the cylinder head 13 due to the structural type of the spark plug 12 itself and the narrow space around the cylinder head 13 and may be caused by oil stains or other factors. Poor, the Mars plug 12 requires special tools (such as a socket wrench) when disassembling and 'has a certain degree of construction difficulty' and thus makes it more difficult to replace or repair the Mars plug 12. [Summary of the Invention] On behalf of the first-hand note, "only if the field is not == slot", it is possible to fully atomize the fuel into the mouth, and further, the power performance and the cylinder-discharge head arrangement mechanism for reducing the blowdown.鱼二' The in-cylinder nozzle-cylinder arrangement mechanism of the present invention is provided on the cylinder of the jet engine of the locomotive.

The fire: plug 42 The first joint portion 24 of the cylinder head 2 is screwed onto the cylinder head 2' and thereby simultaneously tightens the bushing 41 and is also positioned on the cylinder head 2. The sea bushing 41 is sequentially formed with a hexagonal-shaped urging portion 410, a large diameter portion 411 having a notch 415, and a small diameter portion 412 having a recess 416, and the small diameter portion The 412 has a large inner diameter section 413 adjacent to the large diameter portion 4, and a small inner diameter section 414 which is away from the large diameter portion 411 and has an inner diameter of a hexagonal taper. The inner diameter section 414 is for receiving the spark plug 42 and is engaged with the spark plug 42. In the present embodiment, the oil ring 43 is sleeved on the outer wall surface of the small diameter portion 412 of the bushing 41 and is sandwiched between the small pipe diameter portion 412 and the first joint portion 24 of the cylinder head 2. In order to prevent oil and gas leakage. The large inner diameter section 413, the notch 415 formed on the large diameter portion 411, and the recess 416 formed on the small diameter portion 412 are used for accommodating a spark plug 42 having a temperature sensor. However, it should be noted that the Mars plug 42 without the temperature sensor of 200928082 can still be used. The spark plug 42 used in this embodiment is a spark plug 42 with a temperature sensor, but this is not limit. Referring to FIG. 4, it should be noted here that in this embodiment, the ratio of the size between the minimum inner diameter 900 and the maximum inner diameter 8〇〇 of the small inner diameter portion 414 of the small diameter portion 412 is 1:1.5. However, the inner diameter size ratio can be moved within a range of i.1.3 to 1:1.8, depending on actual use or other design considerations. When the spark plug is to be disassembled, a tool (for example, a movable wrench) having a shape and a size corresponding to the biasing portion 410 of the bushing 41 can be used to rotate the bushing 41' and thereby the bushing 41 The small inner diameter section 414 and the spark plug 42 are mutually engaged to drive the spark plug 42 to rotate and disengage from the cylinder head 2, and the inner diameter of the small inner diameter section 414 is gradually retracted. The spark plug 42 is still attached to the bushing 41 when it is unscrewed and is taken out together with the bushing 41 to facilitate the replacement and overhaul of the spark plug 42. In the present embodiment, 'the fuel injection axis 600 of the high-pressure nozzle unit 3 and the axis 700 of the spark plug unit 4 form an angle of 108.5 degrees 0' as defined in FIG. a first imaginary line 400 of the geometric center of the cylinder head 2, the axis 700 of the spark plug unit 4 forms an angle of 0 degrees with the first imaginary line 400, and the high pressure nozzle unit 3 The fuel injection axis 600 forms an angle Θ2 of 47.5 degrees with the first imaginary line 4〇〇. It should be noted, however, that the angle 0 formed between the fuel injection axis 600 of the high pressure nozzle unit 3 and the axis 700 10 200928082 of the spark plug unit 4 can vary within an angle range of 100.5 to 116.5 degrees. It should be noted that after the angle Θ is fixed, the angle 0 1 between the axis 700 of the spark plug unit 4 and the first imaginary line 400 can still be offset within an angle range of 53 to 69 degrees, thereby The angle 0 2 between the fuel injection axis 600 of the high pressure nozzle unit 3 and the first imaginary line 400 is matched in an angular range of 39.5 to 55_5 degrees. In addition, referring to FIG. 5, as shown in FIG. 5, a second imaginary line 500 horizontally penetrating the red head 2 and parallel to the side wall of the cylinder chamber 3 is defined. In this embodiment, an axis of the Mars plug unit 4 and the second imaginary line 500 form an angle α of 9 degrees, and the fuel injection axis of the high pressure nozzle unit 3 also corresponds to the second imaginary line 5 There is no angle between the 〇〇 and a 90 degree. It should be noted, however, that the angle formed between the axis of the Mars plug unit 4 and the second imaginary line 5〇〇 "can vary within an angular range of 85.5 to 94.5 degrees, and the axis of the Mars plug unit 4 The angle formed between the second imaginary line 500 and the second imaginary line 500 can also be varied within an angle range of 85.5 to 94.5 degrees. As shown in Fig. 6, the second comparison of the cylinder head arrangement mechanism of the present invention The preferred embodiment is substantially the same as the first preferred embodiment, and the same is no longer the same. 'The difference is that the spark plug unit 4 has a large tube pinched on the bushing 41. The outer wall surface of the portion 411 is sandwiched between the large diameter portion and the first joint portion 24 of the cylinder head 2. This arrangement can further increase the cylinder head 2 The airtightness makes the oil and gas less likely to leak. The advantages of the present invention are: 200928082 i. The sprayed fuel atomization effect is good, and the combustion is more complete; the present invention utilizes the spark plug unit 4 to penetrate the chain chamber 3〇〇 Extending into the configuration of the combustion chamber 21, and cooperating with the cylinder head 2 away from the chain The nozzle unit 'on one side of the chamber 300 effectively utilizes the space of the cylinder head 2 and makes the distance between the spark plug unit 4 and the high pressure nozzle unit 3 long, and therefore, when fuel is injected into the combustion chamber 21 That is, there is more space and time to mix with the air (atomization) and then be ignited by the spark plug 42 to form an explosion, thereby making the combustion in the combustion chamber 21 more complete, and thereby the good combustion Incompleteness causes loss of power performance and disadvantages of producing highly polluting emissions. 2. The piston 200 of the cylinder 1 does not need to have a guide groove; due to the configuration between the spark plug unit 4 and the high pressure nozzle unit 3 The type relationship is relatively large, so that there is sufficient time and space for the injected fuel to be sufficiently atomized, so that the injected fuel does not need to pass through the guide groove formed on the top surface of the piston 200 as is conventional. Mixing with air 'the piston 2 without the guide groove is simpler in construction (no complicated shape), making it easier to manufacture, thereby reducing production costs, and the structural strength of the simple shape is relatively high, Help Due to the high pressure and high temperature environment in the cylinder 100, the durability of the piston 200 is further improved. 3. The structure of the bushing 41 of the spark plug unit 4, and the group between the bush 41 and the spark plug 42. The relationship between the set 41 and the spark plug 42 having a temperature sensor can be used to rotate the bush 41 by using a spanner wrench or a socket wrench when disassembling and disassembling at 12 200928082. Moving and disengaging from the cylinder head 2, it is not necessary to use a socket wrench as is conventional to disassemble the Mars plug 42, thereby increasing the simplicity of the Mars plug 42 during replacement or overhaul, making it practical. More preferably, the above-described in-cylinder injection cylinder head arrangement mechanism of the present invention is configured such that the bushing 41 of the spark plug unit 4 extends through the chain chamber 3〇〇, so that the fire plug 42 can be fully set. Utilize the space on the cylinder head 2 and increase
