Description

디젤 자동차의 주입연료 판별 및 대처 방법 { METHOD FOR DISTINGUISHING AND MANAGING FUEL INJECTED DIESEL VEHICLE }TECHNICAL FIELD [0001] The present invention relates to a method and apparatus for injecting fuel into a diesel engine,

본 발명은 디젤 자동차의 주입연료 판별 및 대처 방법에 관한 것으로서, 특히 자동차의 연료탱크에 주입된 연료가 적합한 연료인지 여부를 판단하여 엔진의 시동을 허가 또는 차단하도록 하는 디젤 자동차의 주입연료 판별 및 대처 방법에 관한 것이다.The present invention relates to a method for discriminating and handling injected fuel of a diesel vehicle, and more particularly, to a method of discriminating and coping with injected fuel of a diesel vehicle which determines whether fuel injected into a fuel tank of an automobile is suitable fuel, ≪ / RTI >

현재의 자동차는 매우 많은 형태로 변화되어 외관으로 보아 경유를 사용하는지 휘발유를 사용하는지의 구분이 잘 안 되는 경우가 많다.There are many types of cars in the present, and it is often difficult to distinguish whether gasoline or gasoline is used.

따라서, 주유소에서 주유를 할 때 착오로 인하여 잘못된 연료를 공급할 소지가 있으며, 이 경우 주입된 연료가 자동차의 엔진에 공급되게 되면 주요부품의 파손 및 매연발생 등의 문제가 발생한다.Therefore, there is a possibility that a wrong fuel is supplied due to a mistake when gas is supplied from a gas station. In this case, when the injected fuel is supplied to the engine of the vehicle, problems such as breakage of main parts and soot occur.

특히, 최근에는 디젤 승용차가 많이 출시되면서, 이러한 부적합한 연료의 주입이 늘고 있다.In particular, with the recent introduction of many diesel passenger cars, the injection of such improper fuel is increasing.

이를 해결하기 위해, 대한민국 공개특허공보 제10-2004-0009438호, 대한민국 공개특허공보 제10-2006-0038075호 등에는, 주입된 연료를 식별하도록 하는 장치가 나타나 있다.In order to solve this problem, Korean Patent Laid-Open Publication No. 10-2004-0009438, Korean Patent Laid-Open Publication No. 10-2006-0038075 and the like discloses an apparatus for identifying injected fuel.

그러나, 이러한 종래기술에서는 단순히 잘못된 연료가 주입되었다는 것을 운전자에게 알리기만 할 뿐, 그에 따른 적극적인 대처 방법이 제시되지 않았다.However, in this conventional technique, only the driver is informed that the wrong fuel has been injected, and accordingly, an aggressive countermeasure has not been presented.

따라서, 운전자가 잘못된 연료의 주입 후 시동을 걸어 주행을 하게 되면, 상술한 바와 같이 주요부품의 파손 및 매연에 따른 대기오염의 문제가 발생하게 된다.Therefore, when the driver starts to drive after starting the injection of the wrong fuel, the main parts are damaged and air pollution due to soot occurs.

본 발명은 전술한 문제점을 해결하기 위한 것으로써, 디젤 자동차의 연료탱크에 부적합한 연료가 주입되었을 경우에 적극적으로 자동차의 엔진 시동을 차단하여 부적합한 연료가 엔진으로 유입되어 주요부품의 파손 및 매연발생이 되는 것을 미연에 방지할 수 있는 디젤 자동차의 주입연료 판별 및 대처 방법을 제공하는데 그 목적이 있다.Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a diesel engine which is capable of preventing engine startup of an automobile when fuel unsuitable for a fuel tank of a diesel vehicle is injected, The present invention is directed to a method for discriminating an injected fuel of a diesel vehicle and a method for coping with the same.

상기 목적을 달성하기 위하여 본 발명의 디젤 자동차의 주입연료 판별 및 대처 방법은, 자동차의 연료탱크에 주입된 연료가 휘발유인지 아닌지를 판단하는 제1판단단계와; 상기 제1판단단계에서 휘발유가 아니라고 판단된 경우, 상기 연료가 경유, 등유, 혼합유인지 여부를 판단하는 제2판단단계와; 상기 제2판단단계에서 혼합유라고 판단한 경우, 상기 혼합유에서 경유의 혼합비율이 미리 설정된 기준비율에 맞는지 여부를 판단하는 제3판단단계를 포함하여 이루어지되, 상기 제2판단단계에서 상기 연료가 경유라고 판단되거나, 상기 제3판단단계에서 상기 혼합유의 경유 혼합비율이 미리 설정된 기준비율에 맞는 경우에는, 자동차의 시동을 허가하고, 상기 제1판단단계에서 상기 연료가 휘발유이거나, 상기 제2판단단계에서 상기 연료가 등유이거나, 상기 제3판단단계에서 상기 혼합유의 경유 혼합비율이 미리 설정된 기준비율에 맞지 않는 경우에는, 자동차의 시동을 차단하여 시동이 걸리지 않도록 하는 것을 특징으로 한다.In order to accomplish the above object, the present invention provides a method of discriminating and treating an injected fuel of a diesel vehicle, comprising the steps of: determining whether fuel injected into a fuel tank of an automobile is gasoline; A second determination step of determining whether the fuel is diesel, kerosene, or mixed fuel when it is determined that the fuel is not a gasoline in the first determination step; And a third determination step of determining whether the blending ratio of the diesel oil in the blended oil satisfies a predetermined reference ratio if the blended oil is determined to be mixed in the second determination step, The control unit permits the starting of the vehicle when the fuel mixture is determined to be diesel or in the third determination step and the diesel fuel mixture ratio of the mixed oil satisfies a preset reference ratio, and the fuel is gasoline in the first determination step, When the fuel is kerosene, or when the mixing ratio of the diesel oil in the mixed oil does not match a predetermined reference ratio in the third determination step, the starting of the automobile is prevented from being started.

자동차의 시동을 차단하여 시동이 걸리지 않도록 하는 경우에는 정비업체에 비상신호를 전송하도록 한다.If you do not want to start the vehicle by cutting off the vehicle, send an emergency signal to the maintenance company.

상기 제1판단단계 및 제2판단단계에서는 광센서를 이용하여 연료의 투과율에 따라 연료의 종류를 판단한다.In the first determination step and the second determination step, the type of the fuel is determined according to the transmittance of the fuel using the optical sensor.

상기 제3판단단계에서 상기 혼합유의 경유 혼합비율을 판단하는 상기 미리 설정된 기준비율은, 외부온도에 따라 그 값이 변경된다.In the third determination step, the predetermined reference ratio for determining the mixing ratio of the diesel oil of the mixed oil is changed in accordance with the external temperature.

이때, 상기 미리 설정된 기준비율은, 외부온도가 높은 경우에 낮은 경우보다 경유의 혼합비율이 높도록 한다.At this time, the preset reference ratio has a higher mixing ratio of light oil than when the external temperature is high.

이상에서 설명한 바와 같은 본 발명의 디젤 자동차의 주입연료 판별 및 대처 방법에 따르면, 디젤 자동차의 연료탱크에 부적합한 연료가 주입되었을 경우에 적극적으로 자동차의 엔진 시동을 차단하여 부적합한 연료가 엔진으로 유입되어 주요부품의 파손 및 매연발생이 되는 것을 미연에 방지할 수 있다.According to the method for discriminating and handling the injected fuel of the diesel vehicle of the present invention as described above, when the fuel unsuitable for the fuel tank of the diesel vehicle is injected, the engine start of the vehicle is actively blocked and the unsuitable fuel flows into the engine It is possible to prevent the components from being damaged and soot in advance.

도 1은 본 발명의 실시예에 따른 디젤 자동차의 주입연료 판별 및 대처 방법의 순서도,FIG. 1 is a flowchart of a method for discriminating and coping with an injected fuel of a diesel vehicle according to an embodiment of the present invention,

도 1은 본 발명의 실시예에 따른 디젤 자동차의 주입연료 판별 및 대처 방법의 순서도이다.FIG. 1 is a flow chart of the method for discriminating and treating injected fuel in a diesel vehicle according to an embodiment of the present invention.

본 발명의 디젤 자동차의 주입연료 판별 및 대처 방법은 도 1에 도시된 바와 같이, 제1판단단계(S1)와, 제2판단단계(S2)와, 제3판단단계(S3) 등을 포함하여 이루어진다.As shown in FIG. 1, the injected fuel discrimination and coping method of the diesel vehicle of the present invention includes a first judging step (S1), a second judging step (S2), a third judging step (S3), and the like .

상기 제1판단단계(S1)는 자동차의 연료탱크에 연료가 주입되면, 주입된 연료가 휘발유인지 아닌지를 판단한다.The first determining step S1 determines whether the injected fuel is gasoline or not when the fuel is injected into the fuel tank of the automobile.

이때, 주입된 연료가 휘발유인지 여부는 종래의 공지된 다양한 방법을 통해 판단할 수 있고, 그 일예로 광센서 등을 이용하여 그 연료의 투과율에 따라 판단할 수 있다.At this time, whether or not the injected fuel is gasoline can be determined through various known methods. For example, it can be judged according to the transmittance of the fuel using a photosensor or the like.

그에 대한 구체적인 방법은 종래의 공지된 기술을 사용하면 충분한바, 이에 대한 자세한 설명은 생략한다.A detailed description thereof will be given using conventional well-known techniques, and a detailed description thereof will be omitted.

상기 제2판단단계(S2)는 상기 제1판단단계(S1)에서 휘발유가 아니라고 판단된 경우, 상기 연료가 경유, 등유, 혼합유인지 여부를 판단한다.The second determining step S2 determines whether the fuel is diesel, kerosene, or mixed fuel when it is determined that the fuel is not a gasoline in the first determining step S1.

도 1에서는 상기 제2판단단계(S2)를 두개의 단계로 나누어 도시하고 있다.In FIG. 1, the second determination step S2 is divided into two stages.

상기 연료가 경유, 등유, 혼합유(경유가 혼합된 연료)인지 여부는 상기 제1판단단계(S1)와 같이 종래의 공지된 다양한 방법을 통해 판단할 수 있고, 그 일예로 광센서 등을 이용하여 그 연료의 투과율에 따라 판단할 수 있다.Whether the fuel is diesel, kerosene or mixed oil (fuel mixed with diesel) can be determined through various known methods such as the first determining step (S1). For example, using an optical sensor or the like And it can be judged according to the transmittance of the fuel.

상기 제1판단단계(S1)와 제2판단단계(S2)를 합쳐서 한번에 휘발유, 경유, 등유, 혼합유 등을 판단할 수도 있으나, 본 실시예와 같이 나누어 판단하도록 함으로써 고가의 센서를 사용하지 않아도 된다.Gasoline, light oil, kerosene, mixed oil or the like may be determined at one time by combining the first determination step (S1) and the second determination step (S2). However, do.

즉, 휘발유는 경유, 등유, 혼합유와 그 특성이 매우 상이한 바, 상기 제1판단단계(S1)에서는 휘발유만을 검출할 수 있는 저가의 센서를 사용하고, 제2판단단계(S2)에서는 휘발유를 판단함이 없이 경유, 등유, 혼합유만을 구분할 수 있는 저가의 센서를 사용하여, 전체적인 센서 비용을 절감할 수 있다.That is, since the gasoline is very different from the light oil, the kerosene, and the mixed oil, a low-cost sensor capable of detecting only gasoline is used in the first determination step (S1). In the second determination step (S2) By using a low-cost sensor that can distinguish between diesel, kerosene and mixed oil without judgment, the overall sensor cost can be reduced.

상기 제3판단단계(S3)는 상기 제2판단단계(S2)에서 혼합유라고 판단한 경우, 상기 혼합유에서 경유의 혼합비율이 미리 설정된 기준비율에 맞는지 여부를 판단한다.The third determining step S3 determines whether the blending ratio of the light oil in the blended oil satisfies a preset reference ratio when it is determined to be blended in the second determining step S2.

상기 혼합유라 함은, 경우와 기타 다른 연료(등유, 바이오디젤, 신나 등)가 혼합된 것을 의미한다.The mixed type means that a mixture of the case and other fuels (kerosene, biodiesel, thinner, etc.) is mixed.

위와 같은 제1판단단계(S1) 내지 제3판단단계(S3)를 통해, 상기 제2판단단계(S2)에서 상기 연료가 경유라고 판단되거나, 상기 제3판단단계(S3)에서 상기 혼합유의 경유 혼합비율이 미리 설정된 기준비율에 맞는 경우에는, 자동차의 시동이 걸릴 수 있도록 자동차의 시동을 허가한다.If the fuel is judged to be diesel in the second judging step (S2) through the first judging step (S1) to the third judging step (S3), or in the third judging step (S3) When the blending ratio meets a predetermined reference ratio, the start of the vehicle is permitted so that the vehicle can be started.

그리고, 상기 제1판단단계(S1)에서 상기 연료가 휘발유이거나, 상기 제2판단단계(S2)에서 상기 연료가 등유이거나, 상기 제3판단단계(S3)에서 상기 혼합유의 경유 혼합비율이 미리 설정된 기준비율에 맞지 않는 경우에는, 자동차의 시동을 차단하여 자동차의 시동이 걸리지 않도록 한다.If the fuel is gasoline in the first determining step (S1), the fuel is kerosene in the second determining step (S2), or the mixing ratio of the mixed oil is set in advance in the third determining step (S3) If it does not meet the standard ratio, the start of the vehicle is blocked to prevent the start of the vehicle.

이때, 자동차의 시동을 차단하여 시동이 걸리지 않도록 하는 경우에는, 미리 저장된 정비업체에 비상신호를 전송하여 곧바로 정비가 이루어지도록 한다.At this time, when the starting of the vehicle is stopped to prevent starting, an emergency signal is transmitted to a previously stored maintenance company so that maintenance can be performed immediately.

또한, 상기 제1판단단계(S1) 내지 제3판단단계(S3)를 통해, 엔진의 시동을 허가하거나 차단하는 경우에는, 대쉬보드 등을 통해 주입된 연료가 양호한지 불량인지 여부를 운전자에게 알리도록 하여, 운전자가 그에 따라 대처할 수 있도록 한다.When the start or stop of the engine is permitted through the first to the third determination steps S3 to S3, it is determined whether the fuel injected through the dashboard or the like is good or bad, So that the driver can respond accordingly.

위와 같이 디젤 자동차에 부적합한 연료가 주입되었을 경우에, 적극적으로 자동차의 시동이 걸리지 않도록 차단함으로써, 연료탱크로부터 엔진에 연료가 공급되어 엔진 등의 자동차 주요 부품이 손상되는 것을 미연에 차단할 수 있다.When the fuel unsuitable for the diesel vehicle is injected as described above, the engine is actively prevented from starting so that the fuel is supplied to the engine from the fuel tank to prevent the main parts of the automobile such as the engine from being damaged.

또한, 불량 연료 사용의 경우 시동이 걸리지 않기 때문에, 불량 연료 사용에 인한 유독 배기가스의 배출을 미연에 차단하여, 대기 오염에 끼치는 악영향을 막을 수 있다.In addition, since the start-up is not required in the case of using the defective fuel, the discharge of the toxic exhaust gas due to the use of the defective fuel is prevented beforehand, and adverse effects on the air pollution can be prevented.

한편, 상기 제3판단단계(S3)에서 상기 혼합유의 경유 혼합비율을 판단하는 상기 미리 설정된 기준비율은, 외부온도에 따라 그 값 즉 기준비율이 변경되도록 한다.Meanwhile, in the third determination step (S3), the preset reference ratio for determining the mixing ratio of the mixed oil is changed according to the external temperature, that is, the reference ratio.

상기 미리 설정된 기준비율은, 외부온도가 높은 경우에 낮은 경우보다 경유의 혼합비율이 높도록 한다.The predetermined reference ratio makes the mixing ratio of the light oil higher than that when the external temperature is high.

즉, 기준온도에서의 상기 미리 설정된 기준비율을 정하고, 외부온도가 상기 기준온도보다 높으면 상기 기준비율에서 경유의 혼합비율을 높이고, 외부온도가 상기 기준온도보다 낮으면 상기 기준비율에서 경유의 혼합비율을 낮춘다.That is, the predetermined reference ratio at the reference temperature is determined. If the external temperature is higher than the reference temperature, the mixture ratio of the light oil is increased at the reference ratio. If the external temperature is lower than the reference temperature, .

예를 들어, 여름철에는 상기 혼합유에서 상기 경유의 혼합비율이 높도록 상기 기준비율을 변경하고, 겨울철에는 상기 혼합유에서 상기 경유의 혼합비율이 낮도록 상기 기준비율을 변경한다.For example, in the summer, the reference ratio is changed so that the mixture ratio of the light oil is higher in the mixed oil, and the reference ratio is changed so that the mixture ratio of the light oil in the mixed oil is lower in the winter.

이를 통해, 겨울철에도 디젤 엔진에서 시동이 잘 걸리도록 할 수 있다.This allows the diesel engine to start well in the winter.

본 발명인 디젤 자동차의 주입연료 판별 및 대처 방법은 전술한 실시예에 국한하지 않고, 본 발명의 기술 사상이 허용되는 범위 내에서 다양하게 변형하여 실시할 수 있다.The method for discriminating and handling the injected fuel of the diesel automobile according to the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the present invention.
