Description

Rapid heating plugs

본 고안은 디젤 엔진의 시동 보조 플러그에 관한 것이다. 일반적으로 가솔린 엔진과는 달리 디젤 엔진은 초기 시동을 할때 예열플러그를 800도 내지 1100도 까지 예열을 하여 시동이 용이하도록 하는데 걸리는 시간이 3초에서 10초 내외가 걸린다. 또한 동절기에는 예열시간이 길어지고 시동 성이 급격히 떨어진다. 따라서 디젤 자동차를 운전하는 사람들에게는 많은 불편한 점이 되었다. 종래 예열 플러그는 디젤 엔진의 시동모터를 돌리기 전에 미리 예열 과정을 거쳐 가열 부를 뜨겁게 가열시키고 또한 뜨겁게 가열시킨 부분이 실린더 안의 예연소실에 유입되는 차가운 공기와 고압으로 분사되는 연료에 의해 쉽게 온도가 떨어지지 않고 고온을 유지하여 연료를 초기 연소시키기 위해 가열부위가 두껍게 구성되어 있는 반면 열선 전압을 12V로 맞추어 전기 저항을 많게 하여 열선을 보호하면서 가열하다보니 늦게 발열이 되었다. 따라서 종래 예열플러그의 단점은 시동전 예열 과정이 요구되고 예열시킬 때 시간도 많이 걸리는 단점이 있었다. 특히 중고차의 경우에는 압축 열이 제대로 올라가지 않아 예열플러그의 온도에 전적으로 의지해야 하는데 바로 시동이 걸리지 않으면 예열플러그의 온도가 내려가 점화가 잘 안되고 이로 인해 몇 번 반복하여 시동을 걸다보면 밧데리가 방전되어 경정비센타에 도움을 받지 않으면 시동이 불가능한 경우가 종종 일어난다.The present invention relates to a starting auxiliary plug of a diesel engine. In general, unlike a gasoline engine, a diesel engine takes about 3 to 10 seconds to warm up the warming plug to 800 to 1100 degrees during initial start-up. In addition, during the winter, the warm-up time is long and the startability is sharply reduced. Therefore, it has become a lot of inconvenience for people driving diesel cars. Conventional glow plugs have a preheating process before turning the starter of a diesel engine, and the heating part is heated to a high temperature, and the hot heated portion is not easily dropped by the cool air and fuel injected at high pressure into the pre-chamber in the cylinder. In order to keep the high temperature and to burn the fuel early, the heating part is composed of thick, while the heating wire voltage is set to 12V to increase the electrical resistance to protect the heating wire. Therefore, the disadvantage of the conventional preheating plug has a disadvantage that the preheating process is required before starting and takes a lot of time when preheating. Especially in the case of used cars, the heat of compression does not go up properly, so you have to rely solely on the temperature of the preheating plug, but if the starting does not start immediately, the temperature of the preheating plug is lowered and the ignition is not good. It is often impossible to start without assistance from the center.

본 고안은 상기에서와 같은 문제점을 해소하기 위해 병렬코팅열선(h-p-10)을 외부로 돌출 시켜 발열이 빨리 되도록 하였으며 병렬코팅열선(h-p-10)을 컨트롤하는 장치로는 서미스터PTC 열 저항 소자로서 온도에 따라서 전기저항이 크게 변하는 성질을 이용한 스윗치이다. PTC 서미스터에 전압을 가하면 자기가열에 의해서 온도가 상승하고 그에 따라서 전기저항이 크게 올라가 전류의 흐름을 제한한다. 세라믹 PTC 서미스터 소재인 BaTiO3 경우의 큐리점은 약120도이다. 이에 대해 Ba의 일부를 Sr로 치환하면 큐리점은 떨어지고 Pb로 치환하면 큐리점은 역으로 상승한다. 급속서미스터저항컨트롤(90f)의 경우에는 큐리온도를 약 200도에서 사용하고 병렬코팅열선(h-p-10)에 흐르는 전류 량에 의해 자기가열이 되어 전기저항이 생겨전류흐름이 차단될 수 있도록 두께 및 단면 적을 병렬코팅열선(h-p-10)에 맞추어 설정한다. 수온서미스터센서컨트롤(50p)의 경우에는 큐리온도약100도 정도에서 사용하며 두께를 박막으로 하고 단면 적을 크게 하여 병렬코팅열선(h-p-10)에 흐르는 전류에 의해 자기가열이 되지 않아 전기저항이 올라가지 않도록 하며 엔진의 온도에 의해 전기저항이 생기도록 하여 컨트롤한다. 서미스터PTC의 전류 량은 전압단자의 단면적이 넓어지면 전기저항이 적어 전류 량이 많아지고 서미스터PTC두께가 두꺼워지면 전기저항이 커져 전류 량이 작아진다. 따라서 두께를 최대한 얇게 하고 단면적을 넓게 하면 많은 전류를 흐르게 할 수 있다. 두께를 얇게 만드는 장치로서는 진공상태에서 약간의 질소가스를 넣어서 하는 PVD, CVD의 진공 증착 기계로 스퍼터링 을 하여 박막으로 증착을 서미스터PTC 소재로 하면 병렬코팅열선(h-p-10)이 0.5초내에 온도 1000도를 맞추는 조절을 용이하게 설정할 수 있다. 따라서 두께와 단면 적을 조절 하여 사용하고자 하는 부하 측에 맞는 전류 량을 설정 제어하여 부하 측에서 원하는 발열을 할 수 있도록 하면 기존 플러그의 단점을 완전히 해소할 수 있다. 서미스터 종류로는 세라믹 서미스터PTC 또는 폴리머서미스터PTC를 사용할 수 있다. 그리고 병렬리드선(20-1a)에 세라믹접착제(100s-1)로 코팅하여 절연하고 저항열선(90e)을 감을 때 어스 되지 않도록 사용하는 세라믹접착제(100s-1)는 요즘 시중에 많이 판매되는 알루미나 세라믹접착제로 접착성능이 아주 좋아 금속과 금속 또는 세라믹과 세라믹, 세라믹과 금속등 접착력이 우수하고 전기 절연성이 좋은 제품으로 신뢰성이 아주 좋다.In order to solve the above problems, the present invention protrudes the parallel coating heating wire (hp-10) to the outside so that heat can be generated quickly. The device for controlling the parallel coating heating wire (hp-10) is a thermistor PTC thermal resistance element. This switch uses the property that the electrical resistance changes greatly with temperature. When a voltage is applied to the PTC thermistor, the temperature rises due to self-heating, and accordingly, the electrical resistance is greatly increased to limit the flow of current. In the case of BaTiO3, a ceramic PTC thermistor material, the Curie point is about 120 degrees. On the other hand, if a part of Ba is replaced with Sr, the Curie point drops, and if it is replaced with Pb, the Curie point rises in reverse. In the case of the rapid thermistor resistance control (90f), the Curie temperature is used at about 200 degrees, and the heat is generated by the amount of current flowing through the parallel coating heating wire (hp-10), so that the electrical resistance is generated so that the current flow can be blocked. Set the cross-sectional area to match the parallel coating heating wire (hp-10). In the case of water temperature thermistor sensor control (50p), the Curie temperature is used at about 100 degrees, and the thickness is thin and the cross-sectional area is increased so that the electric resistance does not increase due to the self heating due to the current flowing through the parallel coating heating wire (hp-10) Control by making electric resistance by temperature of engine. As the thermistor PTC current is increased, the larger the cross-section of the voltage terminal, the smaller the electrical resistance. Therefore, if the thickness is made as thin as possible and the cross-sectional area is enlarged, a large amount of current can flow. As a device to make the thickness thinner, sputtering with a vacuum deposition machine of PVD and CVD in which a little nitrogen gas is put in a vacuum state, and depositing a thin film as a thermistor PTC material, the parallel coating heating wire (hp-10) is temperature 1000 in 0.5 seconds. The adjustment to match the degree can be easily set. Therefore, it is possible to completely eliminate the disadvantages of the existing plug by adjusting the thickness and the cross-sectional area to control the amount of current suitable for the load side to be used so that the desired heat can be generated on the load side. Thermistor type may be a ceramic thermistor PTC or a polymer thermistor PTC. In addition, the ceramic adhesive (100s-1) used to coat and insulate the parallel lead wire (20-1a) with a ceramic adhesive (100s-1) and not to earth when the resistance heating wire (90e) is wound is alumina ceramic, which is now widely sold in the market. The adhesive has very good adhesive performance, so it has excellent adhesion with metal and metal or ceramic and ceramic, ceramic and metal and has good electrical insulation.

As shown in Figs. 1, 6, and 12, one surface is joined to both sides of the water temperature thermistor sensor control 50p by silver welding 200 to the parallel terminal water thermistor sensor control junction 20d of the parallel terminal 20a. The other side of the water temperature thermistor sensor control 50p is formed by joining one side of both surfaces of the intermediate connection lead 30k with silver solder 200. The other side of the intermediate connecting lead 30k is silver-welded 200 and is bonded to one of both sides of the rapid thermistor resistance control 90f, and the other side of the rapid thermistor resistance control 90f is a parallel lead wire 20-1a. The parallel lead wire thermistor resistance control junction 20-1c, which is the lower end of the wire, is joined by a silver solder 200. Insulate by coating the ceramic adhesive (100s-1) outside the parallel lead wire (20-1a), and then wrap the resistance heating wire (90e) so as not to earth at an appropriate interval, and the lower end of the resistance heating wire (90e) to the intermediate connection lead ( 30k) is welded and joined to the intermediate connection lead resistance hot wire joint portion 90k, and the upper end portion of the resistance wire wire 90e is welded and joined to the parallel lead wire resistance heat bond portion 90g of the parallel lead wire 20-1a. The ceramic molded tube (st) is bonded to the ceramic molded tube adhesive part (s30) by applying a ceramic adhesive (100s-1) to form an external coil parallel heating unit (hh-20), and then a parallel coating heating wire in the spiral heating groove (sta). (hp-10) Wind the parallel coating heating wire (hp-10) and weld one end to the parallel coating heating wire welding site (s10) and the other end to the parallel coating heating wire power welding site (s20) and external coil parallel heating The entire portion (hh-20) is coated with a ceramic coating (s100). The inside of the rapid heating plug is completely compressed and filled with a ceramic adhesive (100s-1), the insulating fixing washer (30g) is inserted into the parallel terminal (20a), and then the fixing washer (10h) is fixed. Referring to the embodiment of the present invention in detail as follows. 1, 6, and 12, when the voltage voltage minus is grounded at the bolt portion 100b and the battery voltage plus is grounded at the parallel terminal 20a, the positive current is the parallel terminal temperature thermistor sensor control junction of the parallel terminal 20a. 20d) is passed through the water temperature thermistor sensor control (50p), and the current flows in two places at the same time at the intermediate connection lead (30k), but the battery receives a 13V voltage toward the rapid thermistor resistance control (90f) with low electrical resistance and a lot of current flows in parallel. The parallel coating heating wire (hp-10) connected to the end of the parallel lead wire (20-1a) through the lead wire speed thermistor resistance control junction (20-1c) generates heat to 1000 degrees within 0.5 seconds. For reference, the rated voltage of the parallel coating heating wire (hp-10) is 3V and the heating temperature of the parallel coating heating wire (hp-10) is from 800 to 1500 degrees. The parallel coating heating wire (hp-10) and the rapid thermistor resistance control according to the product characteristics. Note that you can set it to (90f). At this time, the rapid thermistor resistance control (90f) is a self-heating, the electrical resistance increases rapidly to block the flow of current to protect the parallel coating heating wire (hp-10) and the rapid thermistor resistance control on the parallel coating heating wire (hp-10) When the current flowing to 90f is cut off, the current flows through the resistance heating wire 90e welded to the intermediate connection lead resistance heating wire junction portion 90k in the intermediate connection lead 30k, but the voltage is caused by the resistance heating wire 90e. It flows down to about 3V, which stably heats the parallel coating heating wire (hp-10) to warm up the diesel engine. When the diesel engine receives heat, the engine heat is transferred to the water temperature thermistor sensor control (50p), and when the set Curie temperature is 100 degrees, the electrical term rises rapidly and the current is cut off, and the parallel coating heating wire (h-p-10) stops heating.
