Description
본 고안은 엔진의 냉간시동성 향상장치에 관한 것이다.The present invention relates to an apparatus for improving cold startability of an engine.
엔진의 냉간시동시에는 엔진의 온도가 낮기 때문에 연료의 무화율이 낮아 연소효율이 낮고 배기가스 배출량이 증대되어지게 된다.During cold start of the engine, since the engine temperature is low, the fuel atomization rate is low, resulting in low combustion efficiency and increased exhaust gas emissions.
이 때문에 종래에는 실린더헤드에 에어히터나 글로우플러그(Glow Plug) 등을 설치히여 냉간시동시 흡기포트와 연소실 등의 예열을 시도하고 있으나 이들 복잡한 장치가 실린더헤드에 설치되는 데 따른 실린더헤드의 설계 자유도가 축소, 즉 실린더헤드의 흡배기포트와 밸브, 점화플러그, 인젝터, 및 워터재킷 등에 간섭되어 그의 배치설계가 자유롭지 못하다는 문제점이 지적되고 있다.For this reason, conventionally, air heaters or glow plugs are installed in the cylinder heads to attempt preheating of the intake port and the combustion chamber during cold start. However, the degree of freedom in designing the cylinder heads due to the installation of these complicated devices in the cylinder heads. It has been pointed out that the size of the cylinder head is reduced, that is, it interferes with the intake / exhaust port of the cylinder head, the valve, the spark plug, the injector, the water jacket, and the like, and its layout design is not free.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 엔진의 냉각시동시 인젝션노즐에서의 연료분사 후의 연료량을 이용하여 흡기매니폴드를 가열하여 연료의 무화를 촉진하여 완전연소를 유도하는 엔진의 냉간시동성 향상장치를 제공하는 데 있다.Therefore, the present invention has been proposed in view of the above problems, and its purpose is to heat the intake manifold using the amount of fuel after injection of the fuel in the injection nozzle during engine start-up to promote complete atomization by fuel atomization. The present invention provides an apparatus for improving cold startability of an engine.
상기한 목석을 달성하기 위하여 본 고안은 흡기포트내에 연료를 분사하는 인젝션노즐과, 흡기매니폴드에 장착되어 연료를 연소시키는 버너와 상기 버너를 점화하는 점화기와, 상기 인젝션노즐로부터 분사된 후에 남는 잔량의 연료를 상기 버너에 공급해 주는 연료호스와, 엔진의 냉각수온을 검출하는 수온센서와, 상기 수온센서에 의해 검출된 냉각수온이 기준치 이하인 냉간시동 상태에서 상기 버너에 공급되는 연료를 연소시키는 점화기에 전원을 공급하는 전자제어장치 포함하여 구성되는 것을 특징으로 한다.In order to achieve the above-mentioned wood grain, the present invention provides an injection nozzle for injecting fuel into an intake port, a burner mounted on an intake manifold to burn fuel, an igniter for igniting the burner, and a residual amount remaining after being injected from the injection nozzle. A fuel hose for supplying the fuel to the burner, a water temperature sensor for detecting the coolant temperature of the engine, and an igniter for burning the fuel supplied to the burner in a cold start state where the coolant temperature detected by the water temperature sensor is lower than a reference value. Characterized in that it comprises an electronic control device for supplying power.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention will be described.
제1도는 본 고안에 의한 엔진의 냉간시동성 향상장치를 나다내는 도면으로 도면중 부호 1은 실린더헤드이며 부호 2는 실린더헤드(1)의 흡기포트(3)에 연료를 분사하기 위하여 흡기매니폴드(4)에 의해 지지 장착되는 인젝션노즐이다.1 is a view showing an apparatus for improving the cold startability of an engine according to the present invention, in which 1 is a cylinder head and 2 is an intake manifold for injecting fuel into the intake port 3 of the cylinder head 1. It is an injection nozzle supported by 4).
연료레일(5)을 통해 인젝션노즐(2)에 공급된 연료는 연료분사 시기에만 흡기포트(3)내에 연료를 분사하게 되며 연료분사 후의 잔량의 연료는 연료호스(6)를 통하여 흡기매니폴드(4)에 장착된 버너(8)에 공급된다.The fuel supplied to the injection nozzle 2 through the fuel rail 5 injects fuel into the intake port 3 only at the fuel injection time, and the remaining fuel after the fuel injection is carried out through the fuel hose 6. It is supplied to the burner 8 mounted in 4).
버너(8)에 공급된 연료는 점화기(9)에 의해 점화되어 연소되며 점화기(9)는 전열발열식으로 전자제어장치(10)의 출력신호가 있을 때에만 사용된다.The fuel supplied to the burner 8 is ignited and burned by the igniter 9, and the igniter 9 is used only when there is an output signal of the electronic controller 10 in the heat generation type.
이와같은 본 고안은 엔진이 시동되고 수온센서(11)로부터 검출되는 냉각수온이 정상온도에 이르지 못한 것으로 판정되면, 즉 엔진의 냉간시동 상태라면 전자제어장치(10)가 신호출력하여 점화기(9)로 점화시켜 버너(8)에서 미량의 연료를 연소시키게 되므로써 이때의 연소열로 흡기매니폴드(4)를 통하여 도입되는 신기를 데워 연소실(12)에 공급하게 되는 것이다.The present invention is such that when the engine is started and the coolant temperature detected by the water temperature sensor 11 is determined not to reach the normal temperature, that is, when the engine is cold started, the electronic control device 10 outputs a signal to the igniter 9. By igniting the furnace to burn a small amount of fuel in the burner 8, the fresh air introduced through the intake manifold 4 is heated to supply the combustion chamber 12 with the combustion heat at this time.
이상과 같은 본 고안에 의하면 흡기매니폴드에 버너를 장착하고 인젝션노즐에서 분사되고 남음 연료를 엔진의 냉간시동시에 연소시켜 급송되는 신기를 가열공급하게 되므로써 연료의 무화를 촉진하여 연소효율을 높이게 되며 특히 기존의 예열장치들과 같이 실린더헤드에 장착되지 아니하게 되므로 실린더헤드의 설계자유도를 부여하게 되는 효과가 있다.According to the present invention as described above, the burner is mounted on the intake manifold, injected from the injection nozzle, and the remaining fuel is burned at the cold start of the engine, thereby supplying fresh air to be fed. Since it is not mounted on the cylinder head like the existing preheating devices, the design freedom of the cylinder head is given.
