Description
본 발명은 엔진의 점화코일(ignition coil) 오결선시(誤結線時) 경고방법에 관한 것으로, 특히 점화코일이 부정확하게 결선될 경우 이를 경고함으로써 실린더의 유막파괴 및 마모, 피스톤 및 피스톤 링의 고착 등 엔진의 손상을 미연에 방지할 수 있도록 된, 엔진의 점화코일 오결선시 경고방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a warning method for ignition coil miswiring of an engine. In particular, when the ignition coil is incorrectly connected, the oil film is broken and worn, and the piston and piston rings are fixed. The present invention relates to a warning method for incorrect wiring of an ignition coil of an engine, which prevents damage to the engine.
일반적으로 점화코일은 각 점화 플러그(spark plug)에 불꽂을 튀겨주기 위하여 고전압, 고전류를 발생시키는 엔진부품으로서, 철심에 코일을 200~500회 정도 권취한 1차 코일과, 그 둘레에 보다 가는 직경의 코일을 15000~25000회 정도 권취한 2차 코일로 되어 있다.In general, an ignition coil is an engine part that generates high voltage and high current to ignite a spark plug. Each coil has a primary coil wound around 200 to 500 times and a smaller diameter around the spark plug. Is a secondary coil wound around 15000 to 25000 times.
따라서 배터리의 전류를 점화코일에 단속적으로 흘려 그 2차 코일로 부터 수만 볼트의 유도 기전력을 발생시킴과 동시에 이 기전력을 배전기(distributor)의 로터(rotor)에 공급하여 배전기로부터 점화 플러그로 분배, 유도함으로써 엔진의 점화를 행하도록 한다.Therefore, the battery current flows intermittently through the ignition coil to generate tens of thousands of volts of induced electromotive force from the secondary coil, while supplying this electromotive force to the rotor of the distributor and distributing and inducing it from the distributor to the spark plug. By doing so, the engine is ignited.
이와 같은 점화 코일은 엔진의 부품조립 및 와이어링(wiring)시 배전기 등에 잘못 결선되거나 결선상태가 정확하지 못한 경우가 있으며, 이 경우 실린더의 점화순서가 조기에 이루어지거나 또는 점화순서가 지연되어 엔진의 부조화를 일으키는 문제점이 있었다.Such an ignition coil may be incorrectly connected to a distributor or an incorrect wiring state during assembly and wiring of the engine.In this case, the ignition sequence of the cylinder may be premature or the ignition sequence may be delayed. There was a problem causing disharmony.
더욱이 점화순서가 부정확할 경우에는 차량의 가속시 또는 아이들링(idling)의 장시간지속시 실린더내에 미연소된 연료의 공급으로 인하여 실린더의 내벽면의 유막을 파괴하거나 피스톤의 마모를 촉진시키는 경우가 있으며, 이외에 피스톤 링과 피스톤간의 고착 등의 문제점을 초래하게 된다.In addition, when the ignition sequence is incorrect, the unburned fuel may be destroyed in the cylinder during acceleration of the vehicle or during prolonged idling, which may destroy the oil film on the inner wall of the cylinder or accelerate the wear of the piston. In addition, the piston ring and the piston will cause problems such as sticking.
따라서 올바른 점화순서가 이루어지도록 하기 위해서는 점화코일의 결선이 정확히 이루어져야만 한다.Therefore, the wiring of the ignition coil must be made correctly in order to ensure the correct ignition sequence.
본 발명의 목적은, 이그니션 코일의 오결선시 이를 경고함으로써 즉시 엔진시동을 OFF시킴과 동시에 정비를 유도하는 엔진의 점화코일 오결선시 경고방법을 제공함에 있다.It is an object of the present invention to provide a warning method when an ignition coil is incorrectly connected to an engine to turn off the engine immediately by inducing a warning when an ignition coil is incorrectly connected and to induce maintenance.
본 발명은 상기의 목적을 달성하기 위하여, 크랭크 샤프트(crank shaft)의 각속도(angular velocity) 및 점화순서가 일치하는지의 비교와 점화코일의 1차 전류값에 따라 이를 만족하지 아니한 경우 경고장치를 작동시킴과 동시에 엔진가동을 OFF시키는 특징을 갖는다.In order to achieve the above object, the present invention provides a comparison between the angular velocity and the ignition order of the crankshaft and the operation of a warning device when this is not satisfied according to the primary current value of the ignition coil. At the same time, the engine is turned off.
도1은 본 발명에 따른 플로우 챠트1 is a flow chart according to the present invention.
이하, 본 발명의 구체적인 실시예를 도면을 참조하여 다음과 같이 설명한다.Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.
도1은 본 발명에 따른 플로우 챠트를 나타낸 것으로, 홀 센서 및 크랭크 포지션 센서로부터 현재 크랭크 샤프트의 각도 위치를 감지하되, 크랭크 샤프트의 각도값을 실린더수와 일치하도록 구분하여 크랭크 포지션 센서에 의해 감지된 크랭크 샤프트의 각속도값과 점화순서가 일치하는지를 비교한다.Figure 1 shows a flow chart according to the present invention, while detecting the angular position of the current crankshaft from the Hall sensor and the crank position sensor, by separating the angle value of the crankshaft to match the number of cylinders detected by the crank position sensor Compare the angular velocity value of the crankshaft with the ignition sequence.
크랭크 샤프트의 각속도값과 점화순서가 일치하고 E.C.U(Electronic Control Unit; 이하 E.C.U라함)로부터 점화코일의 1차 전류값이 6A(암페어)이하이면 점화코일의 결선상태가 정상적인 것으로 판단한다.If the angular velocity value of the crankshaft coincides with the ignition sequence and the primary current value of the ignition coil is less than 6 A (ampere) from E.C.U (hereinafter referred to as E.C.U), the connection status of the ignition coil is considered normal.
또한 상기에서 크랭크 샤프트의 위치값과 점화순서가 일치하지 않을 경우에는 경고장치를 ON시켜 이를 경고하고, 경고장치가 ON되면 엔진시동을 OFF시켜 그 가동을 정지시킨다.In addition, when the position value of the crankshaft and the ignition sequence do not match, the warning device is turned on to warn it, and when the warning device is turned on, the engine is turned off to stop the operation.
한편 E.C.U의 1차 전류값이 6A 이상일 경우에도 경고장치를 ON시켜 엔진시동을 OFF시킨다.On the other hand, when the primary current value of E.C.U is more than 6A, turn on the warning device and turn off the engine start.
이처럼 크랭크 샤프트의 위치값과 점화순서가 일치하지 않을 경우 엔진시동을 OFF시킴으로써 엔진의 손상을 미연에 방지한다.In this way, if the position value of the crankshaft and the ignition sequence do not match, the engine is turned off to prevent damage to the engine.
이상과 같이 본 발명 엔진의 점화코일 오결선시 경고방법은, 크랭크 포지션 센서에 의해 감지된 크랭크의 각속도값 및 점화순서가 일치하는지와, 점화코일의 1차 전류값이 기준치를 벗어나는지를 검출하여, 이들 각속도값 및 점화순서가 불일치하고 점화코일의 1차 전류값이 기준치를 벗어날 경우 경고장치를 작동시켜 엔진의 가동을 미연에 정지시킴으로써, 점화코일의 부정확한 결선시 실린더의 유막파괴 및 마모, 피스톤 및 피스톤 링의 고착 등 엔진의 손상을 미연에 방지할 수 있는 효과를 갖는다.As described above, the ignition coil miswiring warning method of the engine of the present invention detects whether the angular velocity value and the ignition sequence of the crank detected by the crank position sensor match and the primary current value of the ignition coil deviates from the reference value. If these angular velocity values and ignition sequence are inconsistent and the primary current value of the ignition coil is out of the standard value, a warning device is activated to stop the engine in advance.If the ignition coil is incorrectly connected, oil film breakage, wear, piston And it is possible to prevent damage to the engine, such as sticking of the piston ring in advance.
