Description

[Detailed description of the invention] The present invention relates to an internal combustion engine that includes a compression ignition engine and a rotary engine, and particularly to an internal combustion engine that includes a compression ignition engine and a rotary engine. The present invention relates to a method and apparatus for conditioning inlet air.

Background technology Prior art involves air conditioning the inlet air of an internal combustion engine to improve efficiency and operation of the engine. There are many proposals aimed at this.

For example, British Patent Specification No. 773115 states that hot air and/or water vapor is The fuel/air mixture is introduced into the fuel/air mixture downstream of the evaporator and the internal combustion engine is fed into a tube at the fuel opening. forming a curtain, the tubular curtain allows the working cylinder to be removed from the carburetor. On the way to the fuel, condensate particles are absorbed, and the condensate particles are evaporated and evaporated. It is stated that the drained condensate can be returned to the fuel and air mixture. child This practically ensures complete combustion of the fuel and reduces fuel consumption. and improved operating conditions for the engine resulting in longer engine life.

On the other hand, British Patent Specification No. 766303 states that upstream of the carburetor, a controlled amount of heat taken from a heating system for heating the interior of a vehicle in response to the air temperature It has been proposed to mix cold air with cold inlet air. The purpose of this proposal is The purpose is to prevent ice from forming in the carburetor.

British Patent Specification No. 1525021 and British Patent Specification No. 1400072 and Other specifications, such as No. 2081377A, use lower octane fuels. Evaporation is added to the inlet air of internal combustion engines to reduce fuel consumption and pollution emissions. It is suggested that care be taken.

One drawback of Okiya's proposals is that they often require complex modifications for American engines. It means to ask for something. Therefore, by combining mechanisms that required substantial redesign, It is necessary to make an engine, and this is why most okiya proposals are not widely used. This is one reason why it was not possible.

Disclosure of invention I believe that the water vapor present in the atmosphere at the intake to the engine condenses into water. It is possible to condition the air at the intake port so that the intake air ( C. Achieves excellent results without the need to add or inject water or steam. I found out what can be done.

According to one feature of the invention, I propose that the Mixing air streams at different temperatures to form water droplets that are transported into the gin This is to condition the intake air that is led to the engine. secondary sky The airflow may be mixed with exhaust gases or indeed engine coolant prior to mixing with main inlet air. is preferably drawn through a heat exchanger for heat exchange with other convenient heat sources. . The mixing is preferably carried out in the carburetor (in the case of gasoline engines). The problem is that it occurs above the venturi. And the mixing is preferably mainly A cross-flow of the main air flow and the supplementary air flow is obtained, creating turbulence and thus ensuring good mixing. It's a shame that it's done to you.

According to another feature of the invention, the inventor provides a main stream air inlet and an auxiliary stream n air inlet. heat that is drawn in and heats the auxiliary air by e.g. heat exchange with the exhaust gas. and an auxiliary air intake containing an exchanger, the auxiliary air intake including Connected to the flow air intake port.

This causes the mainstream air and the auxiliary air to mix at different temperatures, forming water droplets. and the water droplets are carried by the air into the engine. It has a device that supplies gas to one combustion chamber or multiple combustion chambers, and a combustion gas exhaust device. All internal combustion engines are proposed.

Preferably, the mixing occurs downstream of the engine air purifier element and The trick is to process it inside the main stream air intake port of the engine. Usually, air purifier Element Since it is annular, it can be placed inside the air purifier element.

Advantageously, the auxiliary The air inlet is connected to the mainstream air inlet, and a side hole is formed at the end of the guard tube, i.e., the guard tube is A hole in the wall is inserted into the main stream air inlet where the auxiliary air passes through the air purifier element. The holes should be drilled so that they are oriented in opposition to the flow that flows inward in the radial direction. is preferred.

For best results, the temperature difference between the main airflow and the auxiliary airflow should be at least 20°C. , and sweetly.

It should be above 60°C. This can be done in a variety of ways, e.g. By adjusting the flow through the mouth (i.e., changing the size of the auxiliary inlet) The amount of auxiliary air flow to be cooled by or from the heat exchanger to the mixing point This can be achieved by adjusting the length of the tube and the length of the tube used. The material f4 used may vary depending on the specific engine and/or vehicle requirements (and therefore may not be available). Ru. Alternatively, an enlarged chamber, i.e. a condensing device, can be assembled into an auxiliary air inlet. stomach. The airflow t, passing through the engine compartment of a car moving at high speed, is stopped by ui. If the cooling effect is relatively small, relatively small adjustments can cause significant changes in .

The temperature difference between the main air flow and the auxiliary air flow depends mostly on atmospheric conditions. It may or may not be the case, but it seems like 1 and there is no fd. The difference in temperature production does not depend on atmospheric conditions. One reason is that when ambient air is drawn into the mainstream air intake, This means that the air is cooled. Minutes, on hot days, the engine runs hotter therefore, due to the increase in temperature of the supplementary airflow in response to hot days. The temperature increase in the mainstream airflow is offset.

Brief description of the drawing Embodiments of the invention will now be described by way of example with reference to the accompanying drawings.

Of the drawings: FIG. 1 schematically shows an internal combustion engine fitted with a device according to the invention. Figure: and Figure 2 shows the air purifier or air filter of the internal combustion engine shown in Figure 1 from the end. A cut-through cross-section shows how the main airflow and auxiliary airflow are mixed. It shows whether the

Best mode for carrying out the entire invention The engine shown diagrammatically in FIG. The air purifier section has an air filter 10 attached thereto. And the burning sky Air is passed through the venturi 14 to the air filter at a rate counted by the butterfly valve 16. It is sucked in from -10.

Air filter 10 has a main air intake at 18 plus one auxiliary air intake. A mouth is installed. The auxiliary air intake is clamped to the engine exhaust manifold 24. If it is attached to the exhaust manifold 24 of the engine, it will be held in place. , and connected to the air filter by a tube 26 in the form of a collar 22. It contains a converter 20. As shown in FIG.

The pipe 26 enters the air filter 10 from the center of the two sides of the air filter 10. and extends downward within the annular air purifying element 28. The end of tube 26 is closed However, the hole is provided with a supplementary air flow, and the supplementary air flow is partially The intake air of the engine (secondary air flow and a part of it is induced by the mainstream air intake flow C) However, as shown by the arrow in Figure 2, the annular space is Mainstream intake air flowing radially inward through the air cleaning element 28 Perforations are made in the wall of the tube 26 so that the air flows radially outwardly, opposite to the flow of air. It's being carried away. This device creates turbulence and thus separates the main and auxiliary air flows. Ensuring sufficient mixing.

The tube 26 connecting the heat exchanger 20 and the air filter 10 is made of metal, typically is made of copper or partially of a material with lower thermal conductivity (e.g. rubber). In addition, the heating layer 1 may have an auxiliary air flow present at least in the atmosphere. The temperature of the mainstream inlet air should be lowered by an amount sufficient to condense some of the water vapor present. up to high temperatures (and when it is desired to Engines, automobiles, and/'or (r: The condenser 915 may be combined with an expansion chamber (not shown).

In reality, the temperature difference between the main air flow and the auxiliary air flow is 2°C, 1: much larger. stop , and this is almost independent of atmospheric conditions.

Tests on a wide range of vehicles whose internal combustion engines have been partially modified according to the invention Accordingly, fuel consumption could easily be improved by 10% or even 60%.
