Abstract
Description
본 발명은 LPG차량의 에어클리너에 관한 것으로서 특히, LPG차량에서 역화발생시 지속적으로 흡입공기를 여과시킬 수 있는 장치에 관한 것으로써, 여과되지 않은 흡입공기가 엔진내부로 흡입되어 발생하는 차체 손상을 줄여, 내구성과 엔진수명을 증대시키며 경제성과 운행안정성을 향상시킬 수 있는 LPG차량의 에어클리너에 관한 것이다.The present invention relates to an air cleaner of an LPG vehicle, and more particularly, to a device capable of continuously filtering intake air in the event of a backfire in an LPG vehicle, thereby reducing damage to the vehicle body caused by suction of unfiltered intake air into the engine. The present invention relates to an air cleaner for LPG vehicles that can increase durability, engine life, improve economics and operational stability.
일반적으로 LPG차량의 에어클리너는 엔진을 운전하는 데 필요한 공기에 포함된 모래먼지와 이물질을 여과하여, 고속으로 왕복운동하는 피스톤과 실린더벽에 혼합기와 함께 이물질이 흡입되는 것을 방지하는 장치이다.In general, the LPG vehicle air cleaner is a device for filtering the dust and foreign matter contained in the air required to operate the engine to prevent the foreign material is inhaled with the mixer in the piston and cylinder wall reciprocating at high speed.
LPG차량은 엔진특성상 역화가 발생하는 경우가 있다.LPG vehicles may cause backfire due to engine characteristics.
역화란 흡기관 또는 배기관에 정체되어 있는 연료가 점화되어 순간적으로 폭발하는 현상으로, 이 역류하는 공기가 에어클리너를 통하여 외부로 배출되지 못함으로써 커다란 정압파의 힘에 의하여 흡기관에 설치된 공기량 감지 센서 및 흡기시스템이 파손될 수 있고, 이로인해 엔진 시동이 걸리지 않는 문제점이 발생한다.Backfire is a phenomenon in which the fuel stagnated in the intake pipe or the exhaust pipe is ignited and exploded momentarily. The air flow rate sensor installed in the intake pipe by a large positive pressure wave cannot be discharged to the outside through the air cleaner. And the intake system may be broken, thereby causing a problem that the engine does not start.
이러한 문제점을 해결하기 위하여 LPG차량의 에어클리너는 역화발생시 에어클리너의 상부케이싱과 하부케이싱을 체결하는 클램프가 스스로 분리되어 차체손상을 감소시킬 수 있도록 제작된다.In order to solve this problem, the air cleaner of the LPG vehicle is manufactured so that the clamps for fastening the upper casing and the lower casing of the air cleaner are separated by themselves so as to reduce the body damage.
도 1은 종래의 LPG차량의 에어클리너를 도시하는 단면도이며, 도 2는 종래의 LPG차량의 에어클리너의 작용상태를 도시하는 단면도로, 흡기구(12)와 클램프(11)를 구비한 하부케이싱(10)과; 에어호스연결부(21)가 형성되어 상기 하부케이싱(10)과 클램프(11)로 체결되는 상부케이싱(20)과; 상기 하부케이싱(10) 내에 위치하는 에어필터(30)로 구성된다.1 is a cross-sectional view showing an air cleaner of a conventional LPG vehicle, Figure 2 is a cross-sectional view showing the operation of the air cleaner of a conventional LPG vehicle, a lower casing having an inlet (12) and a clamp (11) 10); An upper casing 20 having an air hose connecting portion 21 formed therein and fastened to the lower casing 10 and the clamp 11; It is composed of an air filter 30 located in the lower casing (10).
우선, 상기 흡기구(12)를 통하여 흡입된 공기가 하부케이싱(10) 내부로 흡입되고, 상기 흡입공기는 에어필터(30)를 통과하여 모래먼지나 기타 이물질이 여과되어 상부케이싱(20)의 에어호스연결부(21)를 통하여 에어클리너 밖으로 배출되어 기화기를 거쳐 엔진으로 흡입된다.First, the air sucked through the inlet 12 is sucked into the lower casing 10, and the suction air passes through the air filter 30, and sand dust or other foreign matter is filtered to allow the air of the upper casing 20 to be filtered. It is discharged out of the air cleaner through the hose connection portion 21 and is sucked into the engine via the carburetor.
LPG차량에서 역화발생시, 순간적으로 에어클리너 내부에 커다란 압력이 발생하면, 클램프(11)로 연결된 에어클리너의 상부케이싱(20)과 하부케이싱(10)이 스스로 분리되어 차체손상을 감소시킨다.When the flashback occurs in the LPG vehicle, if a large pressure is generated inside the air cleaner at the moment, the upper casing 20 and the lower casing 10 of the air cleaner connected by the clamp 11 are separated by themselves to reduce the damage to the vehicle body.
그러나, 종래의 LPG차량에서 역화발생시 에어클리너의 상부케이싱(20)과 하부케이싱(10)이 분리되면, 에어필터(30)가 하부케이싱(10)에 잔류하기 때문에 흡입공기를 여과하는 에어클리너의 역할을 할 수 없게 된다.However, when the upper casing 20 and the lower casing 10 of the air cleaner are separated when the backfire occurs in the conventional LPG vehicle, the air cleaner 30 filters the intake air because the air filter 30 remains in the lower casing 10. You will not be able to play a role.
따라서, 모래먼지와 이물질이 기화기를 거쳐서 혼합기와 함께 실린더로 흡입되어 고속으로 왕복운동하는 피스톤과 실린더벽에 끼어서 거친 연마제로 작용하여 실린더벽에 손상을 입히며, 또한 엔진오일에 혼합되어 베어링메탈 등의 각 부분에 마모를 촉진하고 엔진의 수명을 단축 시키는 결점이 있다.Therefore, sand dust and foreign substances are sucked into the cylinder together with the mixer through the carburetor, and are caught in the piston and cylinder wall which reciprocate at high speed and act as a coarse abrasive to damage the cylinder wall. Each part has the drawback of promoting wear and shortening the life of the engine.
본 발명은 상기의 결점을 해소하기 위한 것으로, LPG차량에서 역화발생시 지속적으로 흡입공기를 여과시켜, 여과되지 않은 흡입공기가 엔진내부로 흡입되어 발생하는 차체 손상을 줄여, 내구성과 엔진수명을 증대시키며 경제성과 운행안정성을 향상시킬 수 있는 LPG차량의 에어클리너를 제공하고자 한다.The present invention is to solve the above drawbacks, by continuously filtering the intake air when the backfire occurs in LPG vehicles, reducing the damage to the body caused by the intake of unfiltered intake air into the engine, increasing durability and engine life To provide an air cleaner for LPG vehicles that can improve economics and operational stability.

본 발명의 실시예를 도 3 내지 도5를 참고하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to FIGS. 3 to 5 as follows.
본 발명의 구성은, 도 3에 나타난 바와같이 하측에 흡기구(120)가 형성되고 상측에 다수개의 클램프(110)를 구비한 하부케이싱(100)과; 상부에 에어호스연결부(210)가 형성되고 상기 하부케이싱(100)과 클램프(110)로 조립되는 상부케이싱(200)과; 상기 하부케이싱(100) 내에 위치하여 상기 상부케이싱(200)에 체결된 에어필터(300)와; 상기 에어필터(300)를 상부케이싱(200)에 체결하는 체결수단(400)을 포함하여 구성된다.The configuration of the present invention, as shown in Figure 3 and the inlet port 120 is formed on the lower side and the lower casing 100 having a plurality of clamps 110 on the upper side; An upper casing 200 having an air hose connecting portion 210 formed thereon and assembled with the lower casing 100 and the clamp 110; An air filter 300 positioned in the lower casing 100 and fastened to the upper casing 200; It comprises a fastening means 400 for fastening the air filter 300 to the upper casing (200).
상기 에어필터(300)를 상부케이싱(200)에 체결시에는, 도 3에 도시된 바와같이, 체결수단(400)으로 볼트(410)와 나비너트(420)를 사용할 수도 있으며, 상기 상부케이싱(200)의 모서리 내주면에 나사부를 형성하여 상기 에어필터(300)를 회전시켜 체결 및 해제 할 수도 있다.When the air filter 300 is fastened to the upper casing 200, as shown in FIG. 3, a bolt 410 and a butterfly nut 420 may be used as the fastening means 400, and the upper casing ( A screw may be formed on the inner circumferential surface of the corner 200 to rotate and rotate the air filter 300.
이하, 상기 도 3 내지 도 5를 참고하여 본 발명의 작용 및 효과를 설명하면 다음과 같다.Hereinafter, the operation and effects of the present invention will be described with reference to FIGS. 3 to 5.
상기 흡기구(120)를 통하여 흡입된 공기가 하부케이싱(100) 내부로 흡입되고, 상기 흡입공기는 에어필터(300)를 통과하여 모래먼지나 기타 이물질이 여과되어 상부케이싱(200)의 에어호스연결부(210)를 통하여 에어클리너 밖으로 배출되어 기화기를 거쳐 엔진으로 흡입된다.The air sucked through the inlet 120 is sucked into the lower casing 100, and the suction air passes through the air filter 300 to filter sand dust or other foreign substances, thereby connecting the air hose to the upper casing 200. It is discharged out of the air cleaner through the 210, and is sucked into the engine via the carburetor.
LPG차량에서 역화발생시, 순간적으로 에어클리너 내부에 커다란 압력이 발생하면, 클램프(110)로 연결된 에어클리너의 상부케이싱(200)과 하부케이싱(100)이 스스로 분리되어 차체손상을 감소시킨다.When the backfire occurs in the LPG vehicle, if a large pressure is generated inside the air cleaner at the moment, the upper casing 200 and the lower casing 100 of the air cleaner connected by the clamp 110 are separated by themselves to reduce the body damage.
그러나, 역화가 발생하여 에어클리너의 상부케이싱(200)과 하부케이싱(100)이 분리되어도 상기 상부케이싱(200)에 에어필터(300)가 볼트(410)와 나비너트(420)를 포함한 체결수단(400)으로 고정되어, 흡입공기를 계속해서 여과하기 때문에, 차체 내부로 이물질이 유입되는 것을 방지할 수 있다.However, even if the back casing occurs and the upper casing 200 and the lower casing 100 of the air cleaner are separated, the fastening means including the air filter 300 in the upper casing 200 includes the bolt 410 and the butterfly nut 420. Since it is fixed at 400 and suction air continues to be filtered, foreign matters can be prevented from flowing into the vehicle body.
상기 체결수단(400)은 상부케이싱(200)의 모서리 내주면에 나사부를 형성하여 상기 에어필터(300)를 회전시켜 체결 및 해제 할 수도 있다.The fastening means 400 may be fastened and released by rotating the air filter 300 by forming a screw part on the inner circumferential surface of the upper casing 200.
이상과 같은 본 발명 LPG차량의 에어클리너는 LPG차량에서 역화발생시 지속적으로 흡입공기를 여과시켜, 여과되지 않은 흡입공기가 엔진내부로 흡입되어 발생하는 차체 손상을 줄여, 내구성과 엔진수명을 증대시키며 경제성과 운행안정성을 향상시킬 수 있는 발명인 것이다.The air cleaner of the LPG vehicle of the present invention as described above continuously filters the intake air when the backfire occurs in the LPG vehicle, thereby reducing the damage to the vehicle body caused by the intake of unfiltered intake air into the engine, increasing durability and engine life, and improving economic efficiency. And it is an invention that can improve the operational stability.
