Description

가솔린 직접 분사식 점화기Gasoline direct injection lighter

본 고안은 가솔린 직접 분사식 점화기에 관한 것으로서, 특히 연소실내에 각각 별도로 설치되어 있는 인젝터와 점화플러그를 일체로 구성하여 출력과 연비를 증대시키고, 배기가스의 유해 성분을 줄일 수 있도록 한 것이다.The present invention relates to a gasoline direct injection type igniter, and in particular, the injector and the spark plug which are separately installed in the combustion chamber are integrally configured to increase the output and fuel efficiency and to reduce the harmful components of the exhaust gas.

일반적으로 엔진의 일측에는 연료와 공기가 혼합된 상태의 혼합기를 착화 가능하도록 하는 전기 불꽃을 튀겨 주는 장치가 실린더 헤드의 일측에 설치되어 있으며, 이를 점화장치라 한다.Generally, one side of the engine is installed on one side of the cylinder head to fry the electric spark to enable the ignition of the mixer in a mixture of fuel and air, which is called an ignition device.

이 점화장치의 구성은 배터리, 점화코일, 배전기 및 고압케이블, 그리고 점화플러그로 구성되어져 있으며, 전원 공급은 축전지로부터 점화 스위치를 경유하고 점화코일의 1 차 코일을 통해 배전기의 가동전극으로 폐회로를 형성하도록 전기적으로 연결되어 있다.The ignition system consists of a battery, an ignition coil, a distributor and a high voltage cable, and an ignition plug. The power supply is via the ignition switch from the battery and forms a closed circuit with the movable electrodes of the distributor through the primary coil of the ignition coil. Are electrically connected.

점화플러그는 전극과 절연체 및 셀로 구성되어 있으며, 전극은 중심전극과 접지전극으로 이루어져 있고, 그 사이의 간격은 점화식에 비해 마그넷 점화식이 좁게 되어 있다.The spark plug is composed of an electrode, an insulator and a cell, and the electrode is composed of a center electrode and a ground electrode, and the gap therebetween has a narrow magnet ignition type compared to the ignition type.

절연체는 내열성, 열전도성, 절연성, 기계적 강도가 큰 세라믹을 사용하고, 중심전극은 통형이나 중공으로 구비하여 불꽃 방전이 쉽게 일으키도록 구비되어 있으며, 접점이 열리는 순간 점화1차 코일에 흐르는 전류가 차단됨과 동시에 급격한 자력선의 감소로 인한 고전압이 2차 코일에서 발생하게 된다.The insulator uses ceramics with high heat resistance, thermal conductivity, insulation, and mechanical strength, and the center electrode is provided in a cylindrical or hollow shape so that spark discharge can be easily generated, and the current flowing in the ignition primary coil is blocked at the moment of opening of the contact. At the same time, a high voltage is generated in the secondary coil due to the rapid decrease in the magnetic lines.

2차 코일에서 발생된 고전압은 고압 케이블을 통해 배전기 로터의 회전에 따라 각 점화플러그에 배전되어 플러그의 전극 사이에서 불꽃이 튀어 연소실 안의 혼합기에 점화됨으로 연소가 된다.The high voltage generated in the secondary coil is distributed to each spark plug according to the rotation of the distributor rotor through a high voltage cable, and sparks are splashed between the electrodes of the plug to ignite the mixer in the combustion chamber.

그러나, 연료를 실린더 내로 분사하는 가솔린 직접 분사식 엔진은 헤드의 내측으로 점화플러그와 인젝터가 별도로 설치되어 있음으로 그 구조가 복잡해지고, 연소실의 단면적이 줄어들게 되는 원인으로 출력이 저하되는 문제점이 있다.However, the gasoline direct injection engine for injecting fuel into the cylinder has a problem in that the output is reduced due to the complicated structure of the spark plug and the injector installed inside the head and the reduction of the cross-sectional area of the combustion chamber.

또한, 그 효율이 낮아지게 되어 인체에 유해한 배기가스가 다량으로 발생하게 되는 문제점이 있다.In addition, the efficiency is lowered, there is a problem that generates a large amount of exhaust gas harmful to the human body.

따라서, 본 고안은 위와 같은 문제점을 해결하기 위해 안출한 것으로서, 본 고안은 점화플러그와 인젝터를 일체로 설치하여 연소실의 체적을 넓혀 출력을 증가시킬 수 있도록 하는 가솔린 직접 분사식 점화기를 제공함에 있다.Therefore, the present invention has been made to solve the above problems, the present invention is to provide a gasoline direct injection type igniter to increase the output by increasing the volume of the combustion chamber by integrally installing the spark plug and injector.

In the direct injection type engine in which the exhaust manifold 140 connected to the cylinder head 120 is fixed to the cylinder head 120 and the injector 150 and the spark plug 160 are fixed to the bottom surface of the cylinder head 120, the embodiment of the present invention provides an injector and a spark plug. It consists of being fixed integrally.

수나사(12)가 외측으로 형성된 하우징(10)의 내측으로 점화플러그(30)와 인젝터(40)를 삽입하여 고정하고, 실린더 헤드(20)의 중앙에 암나사(22)를 형성하여 상기 하우징(10)의 수나사(12)를 삽입하는 것으로 구성된다.The spark plug 30 and the injector 40 are inserted and fixed to the inside of the housing 10 in which the male screw 12 is formed outward, and the female screw 22 is formed in the center of the cylinder head 20 to form the housing 10.
