Direct injection type emission reduction carrying device for gasoline engine

Technical Field

The invention relates to the field of automobile accessories, in particular to a direct injection type emission reduction carrying device for a gasoline engine.

Background

The heat efficiency of the currently mainstream automobile core gasoline engine in the market is only about 30% and the combustion efficiency is about 35%, which means that most of heat energy which is ineffective in conversion is still dissipated after oil mixture formed in a cylinder diameter by oil injection of an oil injector and air introduced from an air inlet manifold is ignited, and exhaust gas such as carbon monoxide and harmful substances generated by insufficiently combusted fuel are discharged into the atmosphere from an exhaust pipe.

As is known, excessive exhaust emission is a main factor causing urban haze at present, and it is difficult to further improve combustion efficiency from the engine structure by the manufacturing technology of the present engine, so how to reduce the exhaust emission becomes an important issue concerned by the present public, at the present stage, it is promoted to add ethanol gasoline to reduce the exhaust emission or use a combustion improver to assist the combustion of a gasoline engine to more fully reduce the content of harmful substances in the exhaust, but the emission reduction effect of adding ethanol gasoline is not ideal, and the emission reduction effect of about 30% can be realized at most; the combustion improver is adopted for assistance, so that the carrying equipment of the combustion improver needs to be additionally arranged, the circuit or structural distribution of an engine possibly needs to be changed by additionally arranging the equipment, and the equipment for long-term stable supply of the combustion improver generally needs larger volume and complex structure.

Therefore, how to stably and effectively increase the combustion efficiency of engine fuel by using simple equipment and reduce the content of harmful substances in tail gas is an important key issue in the current automobile and energy-saving and environment-friendly industries.

The working principle is as follows:

the invention relates to a three-way valve of a direct-injection emission reduction carrying device for a gasoline engine, which is arranged between the outlet end of a carbon tank electromagnetic valve of a vehicle and the inlet end of a vacuum tube of an air inlet manifold, and is respectively connected with an original pipeline, the other end of the three-way valve is connected with an oil outlet pipe, when the engine is started and operated, the negative pressure suction force generated in the air inlet manifold is utilized, and the air inlet quantity is adjusted by matching with an air inlet adjusting valve on a locking screw, so that pressure difference is formed between the air inlet adjusting valve and the negative pressure at the bottom in an observation pipe, thereby enabling a combustion improver in the oil storage tank to be sucked into the observation pipe along an oil pipe to realize pressure transfer, after the combustion improver enters the observation pipe, the flow is controlled by a multi-stage throttle valve, then the concentration transfer (or called gradient transfer) of the combustion improver in the oil storage tank is realized by the siphon effect (or capillary effect) of a, when the combustion improver in the oil storage tank is exhausted, a user can inject the combustion improver from the oil injection port by unscrewing the oil injection bolt and then screwing the oil injection bolt again.

The functions of the main components are as follows:

the oil storage tank is used for storing a combustion improver and is provided with an oil injection port and an oil outlet, and the oil storage tank is easy to install in an automobile engine bin due to simple structure.

The oiling bolt is provided with the air inlet adjusting valve, the air inlet hole and the filter element, so that negative pressure can be adjusted, air is filtered to avoid pollution, the oiling bolt is connected with an oiling port on the oil storage tank, oiling can be performed by screwing out, the combustion improver can be prevented from being leaked or polluted by screwing, and the oiling process is simplified.

The wick rope utilizes the siphon effect (or called capillary effect) of the wick rope to realize the concentration transfer of the combustion improver in the oil storage tank, and the combustion improver in the oil storage tank can be continuously and stably conveyed into the oil outlet pipe along the wick rope.

The fixing bolt is used for fixing the positions of the lampwick rope and the observation tube and preventing the lampwick rope from moving in the observation tube due to the action of negative pressure and being incapable of sucking combustion improver to the bottom layer to influence the emission reduction effect of equipment.

The observation tube is made of toughened glass or transparent plastic, has good oil resistance and heat resistance, and is convenient for a user to observe the use condition of the wick rope and the suction condition of the combustion improver.

Defeated oil pipe, defeated oil pipe inserts to the oil storage tank bottom, and the combustion improver in the oil storage tank can directly get into in the observation pipe through defeated oil pipe rapidly when producing the negative pressure.

The throttle valve, because defeated oil pipe direct-suction effect leads to the speed of extracting the combustion improver by negative pressure control, lead to the extraction speed too fast flow too big, cause the waste easily, consequently set up 1 ~ 3 grade throttle valves at the oil-out and control the flow of combustion improver extraction.

The adapter is used for connecting the observation pipe and the oil outlet pipe, the oil outlet pipe is mostly made of rubber, and the adapter can enable the equipment to adapt to the rubber oil outlet pipes with various sizes.

And the three-way valve is used for connecting the direct injection type emission reduction carrying device for the gasoline engine and a pipeline between the outlet end of the carbon tank electromagnetic valve of the original automobile and the inlet end of the vacuum pipe of the intake manifold, and the combustion improver is fed into the engine by utilizing the negative pressure generated by the intake manifold.

The application has the advantages that:

1. the invention has simple structure, small volume and easy installation and maintenance, and does not need to greatly change the component structure and the circuit layout of the engine and the related equipment thereof.

2. The wick rope is matched with the oil injection bolt with the air inlet adjusting valve, the effect of stably providing the combustion improver for the gasoline engine is realized by utilizing the siphon effect of the wick rope and the pressure difference effect of the air inlet adjusting valve, and the effect that the combustion improver cannot be timely provided for the gasoline engine and the emission reduction cannot be realized due to the problems of insufficient suction force or blockage and the like is avoided.

3. The fixing bolt is additionally arranged between the lamp core rope and the observation tube, so that the lamp core rope can not be displaced under the action of negative pressure to influence the use of equipment, and can be easily taken out when the lamp core rope needs to be replaced.

4. The invention is made of toughened glass or transparent plastic, has good heat-resistant and oil-resistant performances, and can be used for observing the oil absorption condition and the using condition of the wick rope by a user through the observation tube, wherein the arc observation tube has a certain radian so as to match the siphon effect of the wick rope and prevent the combustion improver from flowing back.

5. The invention has obvious emission reduction effect, and can continuously provide combustion improver for the gasoline engine for a long time, so the emission reduction effect is reduced by 70 percent compared with the emission limit value, the environmental protection quality is improved, and the oil consumption is reduced by 10 to 30 percent.

6. The invention adopts the oil delivery pipe direct injection type to extract the combustion improver, the combustion improver is more directly and effectively and rapidly extracted in the way, and the flow of the combustion improver is controlled by the multi-stage throttle valve, thereby effectively avoiding the problems of waste and overflow.
