By manufacturing the nozzle body using a super heat resisting alloy, occurrence of troubles in the nozzle body is prevented even if the internal temperature of the combustion chamber is changed rapidly. Accordingly, the durability of the engine body and the nozzle body is improved.

Description

전차용 디젤엔진의 예연소실구조{Prechamber structure of diesel engine for main battle tank}Prechamber structure of diesel engine for main battle tank}

본 발명은 전차용 디젤엔진의 예연소실 구조에 관한 것으로서, 특히 극저온의 환경조건에서 냉간시동시 엔진의 초기시동 성공율이 향상되도록 하고, 하단부가 연소실에 노출되어 있는 노즐체를 초내열 합금강으로서 제작함에 따라 노즐체의 내구성이 향상되어 제품의 수명이 월등히 연장되도록 한 전차용 디젤엔진의 예연소실 구조에 관한 것이다.The present invention relates to the pre-chamber structure of a diesel engine for tanks, and in particular, to improve the initial success rate of the engine during cold start under cryogenic environmental conditions, and to manufacture the nozzle body with the lower end exposed to the combustion chamber as super heat-resistant alloy steel. Accordingly, the present invention relates to a preburn chamber structure of a diesel engine for a tank, in which the durability of the nozzle body is improved and the life of the product is greatly extended.

일반적으로 전차용 디젤엔진 뿐만 아니라 모든 디젤엔진은 연료와 공기를 일정 비율로 혼합한 혼합기를 연소실에 주입하고, 연소실에 주입된 혼합기를 고온, 고압으로 압축하여 자연 발화되도록 하여 폭발시켜 동력을 얻고 있다.In general, all diesel engines as well as tank diesel engines are injected into a combustion chamber by mixing a mixture of fuel and air into a combustion chamber, and the mixture injected into the combustion chamber is compressed to a high temperature and a high pressure to explode by spontaneous ignition. .

이와같이 디젤엔진은 가솔린엔진과 같이 별도의 점화플러그를 사용하지 않고 자연발화법을 이용함에 따라 냉간시동시 저온상태의 혼합기가 연소실내에서 압축되더라도 잘 발화되지 못하는 현상이 발생한다.As such, the diesel engine does not use a separate ignition plug like a gasoline engine, and thus does not ignite well even when the low temperature mixer is compressed in the combustion chamber during cold start.

이러한 현상의 극복을 위해 연소실로 공급되는 혼합기를 일정온도로 예열해주는 예열장치가 제공되고 있다.In order to overcome this phenomenon, a preheating device for preheating a mixer supplied to a combustion chamber to a predetermined temperature is provided.

종래의 예열장치는 예열실을 구비하고 있으며, 일측으로 예열플러그가 삽입되는 몸체와, 상기 몸체에 결합되며 예열된 혼합기를 연소실로 분사하는 노즐체로서 구성된다.The conventional preheating apparatus has a preheating chamber, and is configured as a body into which a preheating plug is inserted into one side, and a nozzle body coupled to the body and spraying a preheated mixer into the combustion chamber.

상기 노즐체에는 복수개의 배출공이 형성되기 마련이며, 몸체와 노즐체는 일반 내열강을 이용하여 제작한다.A plurality of discharge holes are formed in the nozzle body, and the body and the nozzle body are manufactured using general heat resistant steel.

일반적으로 연소실에서 혼합기가 연소될때 연소실 내부는 고온, 고압의 상태가 되며, 상기 노즐체의 하단부는 항시 연소실에 노출되어 있는 상태가 되므로 노즐체는 열충격 및 응력에 견딜 수 있도록 강한 내구성을 갖도록 제작되어야 한다.In general, when the mixer is combusted in the combustion chamber, the inside of the combustion chamber is at a high temperature and high pressure, and the lower end of the nozzle body is always exposed to the combustion chamber, so the nozzle body should be manufactured to have strong durability to withstand thermal shock and stress. do.

그러나, 종래와같이 일반 내열강으로서 제작된 노즐체는 소형의 디젤엔진에 적용하였을때에는 큰 문제점이 발생하지 않으나 극고온과 극저온 상태가 반복되는 전차용 디젤엔진에 적용될 경우에는 일반 내열강으로 제작된 노즐체를 전차용 디젤엔진의 연소실 환경에 견디지 못하고 열충격과 피로응력에 의해 노즐체의 배출공 가공부분에 균열이 발생하거나 부식되는 현상이 빈번하게 발생되고, 이에의해 노즐체와 몸체를 자주 교체해야만 하는 문제점이 발생하였다.However, a nozzle body manufactured as a general heat resistant steel as in the prior art does not have a big problem when applied to a small diesel engine, but a nozzle body made of general heat resistant steel when it is applied to a diesel engine for an electric vehicle having extremely high and low temperature conditions is repeated. It is not able to endure the combustion chamber environment of diesel engines for tanks, and there are frequent occurrences of cracks or corrosion in the exhaust hole processing part of the nozzle body due to thermal shock and fatigue stress, thereby requiring frequent replacement of the nozzle body and the body. This occurred.

따라서, 상기 문제점을 해결하기 위한 본 발명은 실린더헤드의 상단에 설치되어 혼합기의 분사를 위한 인젝터와 혼합기를 예열하기위한 플러그가 결합되고, 그 내부에는 구면형상의 예열실이 형성되어 있는 몸체를 구비하고, 상기 몸체의 하측으로 초내열 합금강으로서 'U'자 모양으로 형성된 노즐체를 특수용접 결합하여 일체화하되, 노즐체의 하단부에 복수개의 배출공을 형성하여 예열된 혼합가스가 연소실로 분사되도록 하므로서, 냉간시동시 엔진의 초기시동 성공율이 향상되도록 하고, 하단부가 연소실에 노출되어 있는 노즐체를 초내열 합금강으로서 제작함에 따라 노즐체의 내구성이 향상되어 제품의 수명이 월등히 연장되도록 한 전차용 디젤엔진의 예연소실 구조를 제공함을 목적으로 한다.Therefore, the present invention for solving the above problems is installed on the top of the cylinder head is coupled to the injector for the injection of the mixer and the plug for preheating the mixer, the inside has a spherical preheating chamber is formed therein; In the lower side of the body, a super heat-resistant alloy steel is formed by integrating a special welding by combining a nozzle body formed in a 'U' shape, and by forming a plurality of discharge holes at the lower end of the nozzle body so that the preheated mixed gas is injected into the combustion chamber. In order to improve the initial start success rate of the engine during cold start and to manufacture the nozzle body with the lower end exposed to the combustion chamber as super heat-resistant alloy steel, the durability of the nozzle body is improved and the life of the product is greatly extended. The purpose of the present invention is to provide a combustion chamber structure.

이하, 첨부된 도면 도 1 내지 도 4 를 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 to 4.

상기 도면에 의하면, 본 발명은 몸체(1)와 노즐체(7)로 대별 구성된다.According to the drawing, the present invention is roughly composed of a body 1 and a nozzle body 7.

상기 몸체(1)는 실린더헤드(10)의 중앙 상단에 결합되는 것으로서, 그 상측으로 혼합기의 분사를 위한 인젝터(11)가 삽입되는 제 1 결합공(3)이 형성되어 있고, 몸체(1)의 일측으로는 인젝터(11)로부터 분사되는 혼합기를 예열시키기 위한 가열수단인 예열플러그(12)가 삽입되기위한 제 2 결합공(3)이 일정각도 경사지게 형성되어 있다.The body 1 is coupled to the top of the center of the cylinder head 10, the first coupling hole (3) into which the injector 11 for the injection of the mixer is inserted thereon, the body (1) One side of the second coupling hole 3 for inserting the preheating plug 12, which is a heating means for preheating the mixer injected from the injector 11 is formed to be inclined at a predetermined angle.

몸체(1)의 하측으로는 노즐체(7)와 연통되기 위한 배출구(5)가 형성된다.A discharge port 5 for communicating with the nozzle body 7 is formed below the body 1.

상기 몸체(1)는 실린더헤드(10)의 상단에 결합되어 연소실의 극고온, 극저온환경에 충분한 내구성을 가지는 내열합금강으로 제작한다.The body 1 is coupled to the upper end of the cylinder head 10 is made of a heat-resistant alloy steel having sufficient durability in the extremely high temperature, cryogenic environment of the combustion chamber.

노즐체(7)는 그 하단부가 전차용 디젤엔진의 연소실에 직접 적으로 노출되므로 고온, 고압에서의 열응력 및 충격에 대하여 보다 우수한 내구성을 갖는 초내열 합금강으로 제작한다.The nozzle body 7 is made of super heat-resistant alloy steel having a better durability against thermal stress and impact at high temperature and high pressure because its lower end is directly exposed to the combustion chamber of a diesel engine for a tank.

노즐체(7)는 마찰용접법에 의해 몸체(1)의 하단에 결합하여 몸체(1)와 노즐체(7)가 일체화되도록 하며, 노즐체(7)의 하단부 외주면상에는 8개의 배출공(8)을 형성하였다.The nozzle body 7 is coupled to the lower end of the body 1 by friction welding so that the body 1 and the nozzle body 7 are integrated, and eight discharge holes 8 are provided on the outer peripheral surface of the lower end of the nozzle body 7. Formed.

상기 배출공(8)들은 도 2 와 도 3 에 도시된 바와같이 노즐체(7)에 대해 일정각도 하향 경사지도록 하여 배출공(8)을 통해 배출되는 예열된 혼합기가 연소실에 넓게 퍼지면서 분사되도록 하였다.The discharge holes 8 are inclined downwardly at an angle with respect to the nozzle body 7 as shown in FIGS. 2 and 3 so that the preheated mixer discharged through the discharge holes 8 is widely spread in the combustion chamber. It was.

그리고, 상기 배출공(8)의 안쪽, 즉, 배출공(8)을 형성하는 노즐체(7)의 내측 벽면 모서리부분(A)을 둥글게 마감처리하여 배출공(8)으로 배출되는 혼합기의 흐름을 원활하게 하고, 열충격 및 피로응력에 따른 균열발생을 방지할 수 있도록 하였다.Then, the inside of the discharge hole 8, that is, the inner wall surface edge portion (A) of the nozzle body 7 forming the discharge hole 8 is roundly closed to the flow of the mixer discharged to the discharge hole (8) It was made to smoothly and to prevent the occurrence of cracks due to thermal shock and fatigue stress.

도 4 는 본 발명의 예연소실 구조가 k-1 전차용 디젤엔진의 실린더헤드에 적용된 상태를 도시한 것이다.Figure 4 shows the pre-chamber structure of the present invention is applied to the cylinder head of the diesel engine k-1 tank.

몸체(1)의 하단에 노즐체(7)가 결합되어 일체화된 상태로 실린더헤드(10)의 중앙 상단부에 결합되어 있고, 몸체(1)의 상측으로 혼합기의 분사를 위한인젝터(11)가 결합되며, 몸체(1)의 일측으로 혼합기의 예열을 위한 예열플러그(12)가 삽입되어 있다.The nozzle body 7 is coupled to the lower end of the body 1 is coupled to the central upper end of the cylinder head 10 in an integrated state, the injector 11 for the injection of the mixer to the upper side of the body 1 is coupled The preheating plug 12 for preheating the mixer is inserted into one side of the body 1.

이와같이 구성되는 본 발명의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

엔진 초기시동시 먼저 예열플러그(12)에 전원이 공급되어 가열되고, 이상태에서 인젝터(11)를 통해 일정양의 혼합기가 분사되어 예열실(2)에 공급된다.When the engine is initially started, power is supplied to the preheating plug 12 and heated. In this state, a predetermined amount of the mixer is injected through the injector 11 and supplied to the preheating chamber 2.

예열실(2)로 공급된 혼합기는 구면형상의 예열실(2) 내에서 와류되면서 예열플러그(12)에 접촉되어 순간적으로 예열되고, 예열실(2)에서 예열된 혼합기는 노즐체(7)의 배출공(8)을 통해 연소실로 공급되는 것이다.The mixer supplied to the preheating chamber 2 is vortexed in the spherical preheating chamber 2 and in contact with the preheating plug 12 for instant preheating, and the preheating mixer in the preheating chamber 2 is nozzle body 7. It is supplied to the combustion chamber through the discharge hole (8).

이때, 상기 연소실로 공급된 혼합기는 이미 예열실(2)에서 일정온도로 예열된 상태이므로 피스톤의 압축과정에서 발화가능한 온도와 압력으로 압축되면서 자연발화가 촉진되는 것이다.At this time, since the mixer supplied to the combustion chamber is already preheated to a predetermined temperature in the preheating chamber 2, spontaneous ignition is promoted while being compressed to a temperature and pressure that can be ignited during the compression of the piston.

즉, 본 발명의 예연소실구조를 이용하면 대기온도가 아주 낮은 냉간시동시에도 연소실로 공급되는 혼합기의 온도가 일정온도 이상의 상태로 예열되므로 그만큼 초기시동 성공율이 향상되는 것이다.That is, when the preburner chamber structure of the present invention is used, the initial startup success rate is improved because the temperature of the mixer supplied to the combustion chamber is preheated to a predetermined temperature or more even during cold start with a very low atmospheric temperature.

그리고, 본 발명에 적용되는 노즐체(7)가 고온, 고압의 상태에서도 높은 내구성을 갖는 초내열 합금강으로서 제작됨에 따라 전차용 디젤엔진의 연소실 내부온도가 극저온과 극고온 상태를 반복하더라도 노즐체(7)의 이상현상이 발생하지 않게되는 것이다.In addition, since the nozzle body 7 applied to the present invention is manufactured as a super heat-resistant alloy steel having high durability even in a high temperature and high pressure state, even if the internal temperature of the combustion chamber of a diesel engine for a tank repeats a cryogenic and an extremely high temperature state, the nozzle body ( The abnormal phenomenon of 7) does not occur.

따라서, 디젤엔진에 적용되는 몸체(1)와 노즐체(7)의 수명이 연장되는 효과를 기대할 수 있게되는 것이다.Therefore, it is possible to expect the effect of extending the life of the body 1 and the nozzle body 7 applied to the diesel engine.

이상에서 설명한 바와같이 본 발명은 실린더헤드의 상단에 설치되어 혼합기의 분사를 위한 인젝터와 혼합기를 예열하기위한 플러그가 결합되고, 그 내부에는 구면형상의 예열실이 형성되어 있는 몸체를 구비하고, 상기 몸체의 하측으로 초내열 합금강으로서 'U'자 모양으로 형성된 노즐체를 특수용접 결합하여 일체화하되, 노즐체의 하단부에 복수개의 배출공을 형성하여 예열된 혼합가스가 연소실로 분사되도록 하므로서, 냉간시동시 엔진의 초기시동 성공율이 향상되도록 하고, 하단부가 연소실에 노출되어 있는 노즐체를 초내열 합금강으로서 제작함에 따라 노즐체의 내구성이 향상되어 제품의 수명이 월등히 연장되도록 한 전차용 디젤엔진의 예연소실 구조를 제공하는 효과를 기대할 수 있다.As described above, the present invention is installed on the upper end of the cylinder head is coupled to the injector for the injection of the mixer and the plug for preheating the mixer, the inside has a body having a spherical preheating chamber is formed, It is integrated with the special welding by welding the nozzle body formed of 'U' shape as super heat-resistant alloy steel to the lower side of the body, and forming a plurality of discharge holes at the lower end of the nozzle body so that the preheated mixed gas is injected into the combustion chamber. Preheating success rate of diesel engine for tanks that improved the success rate of initial start-up of engine and improved nozzle durability by making nozzle body exposed to combustion chamber at the lower end as super heat-resistant alloy steel.
