Abstract

본 발명은 디젤자동차의 배기가스 저감기술의 하나인 후처리장치의 매연여과방식에서 필터에 쌓인 입자상물질(매연)을 태우는 과정(재생)에서 매연의 착화온도를 고온에서 상대적으로 낮추기 위하여 첨가제를 공급하는바, 특히 연료탱크와 엔진의 연료공급펌프사이에 디젤유와 첨가제를 일정한 혼합비율로 공급하는 차량탑재형 첨가제 자동공급장치에 관한 것으로, 종래의 수동작업을 통해 연료의 주입량에 맞추어 첨가제를 연료탱크에 주입량에 맞추어 첨가제를 연료탱크에 주입했을때, 불충분한 교반작용과 디젤유와 첨가제의 비중차에 의해 발생된 연료의 분리현상에 따라 매연이 첨가제를 함유하지 않거나 또는 최적치보다 높거나 낮은 상태로 불규칙하게 함유되어 매연여과정치의 필텨에 쌓이게 되는바, 이 매연의 재생시에는 매우 높은 착화온도가 필요로 하고 또한 재생이 불규칙하고 불완전할 뿐만 아니라 필터내에서 매연이 탈때 불균일한 온도분포와 국부적인 온도상승으로 열적충격을 받아 필터가 손상되며 차량의 운행에도 무리를 주게 된다.The present invention supplies an additive to relatively reduce the ignition temperature of the soot at high temperatures in the process of burning particulate matter (soot) accumulated in the filter in the soot filtration method of the after-treatment apparatus, which is one of the exhaust gas reduction technologies of diesel vehicles. In particular, the present invention relates to a vehicle-mounted additive automatic supply device for supplying diesel oil and additives at a constant mixing ratio between a fuel tank and a fuel supply pump of an engine. When the additive is injected into the fuel tank in accordance with the amount injected into the tank, the smoke does not contain the additive or is higher or lower than the optimum value due to insufficient agitation and separation of fuel caused by the specific gravity difference between the diesel oil and the additive. It is contained irregularly and accumulates in the filter of smoke soot value. Degrees requires, and also reproducing the irregular and receives a thermal shock in a temperature distribution and a localized temperature increase, as well as the exhaust talttae irregularity in the filter is not complete, and the filter is damaged, is dropped in a flock operation of the vehicle.

이러한 점을 착안하여 본발명은 연료속에 일정한 량의 첨가제가 균일하게 분포될 수 있게 하여 연료의 연소후 발생된 매연속에 첨가제의 성분이 균일한 분포상태가 되도록 유지시켜 줌으로써, 이 매연의 재생시 상대적으로 낮은 온도에서 착화될 뿐만 아니라 안정적이고 완전한 재생을 이루도록 하며, 또한 필터내에서 안정된 재생온도를 유지시켜 급속한 열적충력으로부터 필터가 손상되는 것을 방지하여 매연여과효율과 매연여과장치의 성능이 지속되도록 함과 동시에 차량의 운행상태가 정상적으로 이루어질 수 있게 한 것이다.With this in mind, the present invention allows a uniform amount of additives to be uniformly distributed in the fuel, thereby maintaining a uniform distribution of the additives in the soot generated after combustion of the fuel. It not only ignites at low temperature but also achieves stable and complete regeneration, and also maintains stable regeneration temperature in the filter to prevent damage of the filter from rapid thermal shock, so that the efficiency of soot filtration and soot filtration is maintained. At the same time, the driving state of the vehicle can be made normally.
