제1도는 본 장치의 종단면도이고.1 is a longitudinal sectional view of the apparatus.

제2도는 본 장치중 일부 부품을 사시도로 표현한 것이다.2 is a perspective view of some components of the apparatus.

본 장치는 가솔린 기관의 연료 분사 공급계통에 가솔린 이외의 보조연료를 적절히 공급하기 위한것인데 특히, 엔진의 고속회전시에만 보조연료가 집중적으로 공급되게하여 가솔린을 절약하고자 하는 것이다.This apparatus is to properly supply auxiliary fuels other than gasoline to the fuel injection supply system of a gasoline engine. In particular, it is intended to save gasoline by intensively supplying auxiliary fuel only at high speed of engine rotation.

본 장치를 첨부된 도면에 의하여 상세하게 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.

몸체(1)에 공기 유통로(2)를 만들어 보조연료 분사노즐(3)을 접속하여 공기 유통로(2) 입구(4)에는 체크밸브(5)를 장치하고, 공기 유통로(2)의 출구(10)와 접속되는 분사관(13)은 판(14)에 큰 구멍(15)을 뚫어 그 내벽에 경사 안내 깃(15')을 설치하며, 또, 공기유통로(2)의 출구(10)와 접속되는 고리형 통로(16)를 큰 구멍(15) 주위판(14)속에 설치하여 큰 구멍(15) 내벽의 작은 구멍(17) 몇 개로 통로(16)와 통기되게 한 공지의 것에 있어서 공기유통로(2)의 중간(6) 밀폐된 방(7)을 고무판(8)으로 막고 고무판 위의 융기부(8')가 통로(2) 중간(6)을 여닫게하는 공기변체(9)를 장치하고, 공기유통로(2)의 출구(10)에는 나봉(11)으로 여닫게 된 보조통로(12)를 형성한 것이다.An air flow passage 2 is formed in the body 1 to connect the auxiliary fuel injection nozzle 3 to the inlet 4 of the air flow passage 2, and a check valve 5 is installed in the air flow passage 2, The injection pipe 13 connected to the outlet 10 drills a large hole 15 in the plate 14 and installs an inclined guide vane 15 'on the inner wall thereof, and the outlet of the air flow path 2 ( The annular passage 16 connected to the 10 is provided in the periphery plate 14 of the large hole 15 so that a few holes 17 of the inner wall of the large hole 15 allow the passage 16 to be ventilated. In the air passageway (2) to close the sealed room (7) with a rubber plate (8), and the air valve (8 ') on the rubber plate to open and close the middle (6) of the passage (2) ( 9), and the auxiliary passage 12, which is opened and closed by the low rod 11, is formed at the outlet 10 of the air flow passage 2.

미설명부호 9'는 공기 변체의 변좌이고, 9＂는 변좌의 공기가 통하는 홈이다.Reference numeral 9 'is the toilet seat of the air variant, 9 ＂is the groove through which the air of the toilet seat.

작용효과를 설명한다.Describe the effect.

공지의 장치에 있어서는 가솔린 기관의 공기흡입도관(18)의 임의의곳을 판(14)이 가로막게 설치하여 가솔린 기관의 흡입공기가 판(14)의 큰 구멍(15)을 통하여 직진케하고, 가솔린 기관을 가동하면 가솔린 기관의 흡입행정시에 공기흡입도관(18)에는 빠르고 강력한 힘의 공기가 흐르게 되어 이때 공기는 일정한 힘의 흡입력으로 입구(4)의 체크벨브(5)를 열고 공기유통로(2)를 빠르게 통기됨에 의하여 공기유통로(2)에 집속된 보조연료 공급노즐(3)에서는 보조연료가 원만히 흡입분사되고, 이 분사된 보조연료는 공기와 함께 분사관(13) 큰 구멍(15) 주위의 고리형 통로(16)와 그 내벽의 작은 구멍(17)들을 통하여 가솔린 기관의 흡입 공기와 섞이게 되는데, 이때 가솔린 기관의 도관(18)내에 흐르는 공기는 분사관(13)의 큰 구멍(15)을 지나면서 그 내벽의 경사 안내깃(15')에 닿아 회오리 현상이 일어나므로 도관(18)내에 흐르는 공기와 분사된 보조연료의 혼합을 촉진하게 되는 것이므로 보조연료의 공급량은 불안정한 체크밸브(5)의 작용에만 의존하게 되어 보조연료가 엔진이 저속회전시에도 항상 공급되는 폐단이 있는 것이다.In the known apparatus, any portion of the air intake conduit 18 of the gasoline engine is installed so that the plate 14 blocks, so that the intake air of the gasoline engine goes straight through the large hole 15 of the plate 14, When the gasoline engine is operated, a fast and powerful air flows through the air intake conduit 18 during the intake stroke of the gasoline engine. At this time, the air opens the check valve 5 of the inlet 4 with a constant suction force and opens the air passage. In the auxiliary fuel supply nozzle (3) focused on the air flow path (2) by rapidly venting (2), the auxiliary fuel is smoothly injected and injected, and the injected auxiliary fuel is injected into the injection pipe (13) with a large hole ( 15) through the annular passageway 16 and the small holes 17 of the inner wall thereof, it mixes with the intake air of the gasoline engine, wherein the air flowing in the conduit 18 of the gasoline engine is a large hole of the injection pipe 13 (15) passing through the inclined guide feather on the inner wall (15) As a result of a tornado phenomenon, it is promoted a mixture of the air flowing into the conduit 18 and the injected auxiliary fuel, so that the supply amount of the auxiliary fuel depends only on the operation of the unstable check valve (5). There is a closed end that is always supplied even at low speed rotation.

그러나 본 고안에 있어서는 고무판(8)으로 막은 밀폐된 방(7)과 가솔린 기관의 공기 흡입도관(18) 임의의 곳을 도관 등으로 접속하게 되면 엔진의 가동시에 밀폐된 방(7)에 진공력이 작용하여 밀폐된 방(7)을 막는 고무판(8)은 밀폐된 방(7)의 진공력으로 방(7)내로 둥글게 융기되어 내려와 그 위의 융기부(8')가 막고 있는 공기유통로(2)에 변좌(9')의 홈(9＂)을 노출시키므로 이 홈을 통하여 통로(2)의 중간(6)을 열게 되는데, 이 공기변체(9)의 작용은 가솔린 기관의 흡입 공기에 의하여 밀폐된 방(7)에 발생하는 진공력에 의한 것으므로 가솔린 기관의 공기 흡입도관(18) 내에 흐르는 공기의 속도 즉 회전속도 비에 지배된다.However, in the present invention, if the airtight room 7 closed by the rubber plate 8 and the air inlet conduit 18 of the gasoline engine are connected by conduits or the like, the vacuum is stored in the airtight room 7 when the engine is operated. The rubber plate 8 which acts to block the sealed room 7 is raised upwardly into the room 7 by the vacuum force of the sealed room 7 and the air flow block that the ridge 8 'above is blocked. Since the groove 9 'of the toilet seat 9' is exposed to the furnace 2, the middle 6 of the passage 2 is opened through this groove, and the action of the air variant 9 is caused by the intake air of the gasoline engine. As a result of the vacuum force generated in the enclosed room 7, the speed of the air flowing in the air intake conduit 18 of the gasoline engine is controlled.

즉, 밀폐된 방(7) 내의 일정한 진공력과 통로(2)에 작용하는 일정한 흡인력이 공기변체(9)와 체크밸브(5)의 작동조건이 되고, 이러한 조건을 갖춘때에만 공기유통로(2)에 신속한 통기가 이루어지는 것이다.That is, the constant vacuum force in the sealed room 7 and the constant suction force acting on the passage 2 become the operating conditions of the air deflection 9 and the check valve 5, and the air flow path ( In 2) rapid aeration is achieved.

그러므로 엔진의 고속회전시에 도관(18) 내에 흐르는 강력하고 빠른 공기가 공기변체(9)를 크게 열어 공기유통로(2)에 흐르는 공기의 유속을 증대시키므로 이때에 집중적으로 보조 연료를 분사시키게 된다.Therefore, the strong and fast air flowing in the conduit 18 during the high-speed rotation of the engine opens the air deformation 9 to increase the flow rate of the air flowing in the air flow path (2), thereby intensively injecting the auxiliary fuel at this time .

그리고 이러한 보조연료 공급량의 자동 기능이 필요치 않을때에는 나봉(11)을 돌려 보조 공기통로(12)를 열어서 공기가 공기 유통로(2)를 거칠 것 없이 보조연료 분사노즐(3)을 거쳐 분사관(13)을 통하여 공기도관(18)에 도입케 한다.And when the automatic function of the auxiliary fuel supply amount is not necessary, open the auxiliary air passage 12 by turning the nabong 11 so that the air passes through the auxiliary fuel injection nozzle 3 without passing through the air flow passage 2 and the injection pipe ( 13) through the air conduit (18).

이상과 같은 본 고안은 가솔린의 연료 공급계통에 엔진의 고속 회전시에만 집중적으로 공급할 수 있는 우수한 장치를 제공하는 것이다.The present invention as described above is to provide an excellent device that can be intensively supplied only at high speed rotation of the engine to the fuel supply system of gasoline.
