Dielectric barrier fuel charge device

Abstract

The invention discloses a dielectric barrier fuel charge device, and belongs to the technical field of fuel engine pretreatment devices. The dielectric barrier fuel charge device comprises a fuel charge mechanism, the fuel charge mechanism is connected with an installation damping device, the installation damping device comprises a connecting mechanism, the connecting mechanism comprises an upper connecting semi-ring and a lower connecting semi-ring, the upper connecting semi-ring is connected with a damping mechanism, and the lower connecting semi-ring is fixedly mounted on the upper connecting semi-ring through a fixing bolt; and the two ends of the fuel charge mechanism are connected with communicating pipes, and the ends, away from the fuel charge mechanism, of the communicating pipes are connected with a first fuel filtering device and a second fuel filtering device correspondingly. The problems that existing design is poor in purification effect, high in cost and large in operation difficulty, the connecting manner between a filter and an oil conveying pipeline is simpler, the sealing performance is poor, and leakage and falling off are prone to occurring are effectively solved.

Description

technical field [0001] The invention relates to the technical field of fuel engine pretreatment devices, in particular to a dielectric barrier fuel charging device. Background technique [0002] The formation of fuel mixture in diesel vehicles is carried out in the combustion chamber of the engine. Diesel is injected into the combustion chamber at high pressure, compressed and ignited, and then burned while spraying. This way of working determines that the mixture of diesel and air is not uniform, and there will inevitably be local oxygen deficiency or local oxygen enrichment. When oil is exposed to high temperature and lack of oxygen, it is easy to carbonize and form soot. The adjustment of diesel vehicle load is controlled by changing the fuel injection quantity. Under the current diesel technical conditions, the fuel-saving rate of diesel vehicles is limited. If more than 2% of the fuel-saving effect is to be obtained, additional technical means must be introduced to as...

Problems solved by technology

[0003] In order to reduce fuel consumption and appropriately reduce the emission of CO, HC, nitrogen oxides (NOx) and particulate matter (PM) synchronously, the prior art generally adopts the following two methods: 1. Add other types of fuel additives to the engine, which needs to be regularly The addition of additives increases the cost of users on a regular basis. In many cases, it does not have the effect of reducing both nitrogen oxides (NOx) and particulate matter (PM). It often only reduces one of the indicators, while the other indicators will rise instead. It is not a way to solve the problem at the root; 2. Adopt post-processing technology, that is, DPF+SCR technology. This double-drop technology has a strong purification effect, but the disadvantage is that the post-processing equipment needs to be cleaned regularly, and the cost of the pre- and post-processing is equal It is very tall and requires a lot of space, so it is very difficult to manufacture and install; in addition, in order to better ensure the combustion efficiency of fuel, before the fuel is injected into the engine, it is necessary to use a filter to filter the fuel gas. Harmful particles and water in the system are filtered out, while the common oil pipelines and filters on the market are usually plugged in, the connection is not firm, and it is easy to leak or even fall off. In addition, the filter The filter is usually installed directly on the chassis of the car, and the vibration during driving is more likely to cause the oil pipeline to fall off and the filter itself to be damaged. In view of this, we propose a dielectric barrier fuel charging device
