FIELD

The present disclosure generally relates to the field of internal combustion engine, and more particularly to air cooling chamber assemblies to increase intake ambient air density and oxygen molecules to improve fuel efficiency of the internal combustion engines, and the internal combustion engines having the air cooling chamber assemblies.

BACKGROUND

The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.

Internal combustion engine uses energy by burning the mixture of fuel and air to produce power. In order to improve fuel consumption rate of the internal combustion engine, many engines employ turbocharger, in which the power of the exhaust gas turns the turbine that is mechanically connected to an air-blower for supplying and compressing the filtered intake ambient air into the engine. The objective of a turbocharger is to improve an engine’s efficiency by increasing the density of the intake air by compressing the intake air before the intake air enters the intake manifold of the internal combustion engine. This results in a greater mass of air entering the cylinders on each intake stroke thereby allowing more power per engine cycle. However, temperature of the pressurized air or charge air can rise as high as 150 °C, as a result, the density of the charge air will be reduced. This affects the performance of the original intention to improve the fuel efficiency.

The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Like reference numerals refer to like elements throughout.

It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present disclosure.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including” or “has” and/or “having” when used herein, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.

Furthermore, relative terms, such as “lower” or “bottom”, “upper” or “top,” and “front” or “back” may be used herein to describe one element’s relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements.

In another aspect, the present disclosure relates to an internal combustion engine 200. In certain embodiments, as shown in FIG. 2, the internal combustion engine 200 includes an air cooling chamber assembly 100. The air cooling chamber assembly 100 includes: an air intake duct 102, an air cooling chamber 104, and an air output duct 106. The air intake duct 102 has a first end 1021 and a second end 1022, and the air intake duct 102 receives ambient air 301 at the first end 1021 outside of the internal combustion engine 200.

In one embodiment, the cooling device 400 is a separate compressor based cooling system. The compressor based cooling system includes a compressor for compressing the gaseous refrigerant resides in the system into a high temperature, high pressure gaseous refrigerant. The high temperature, high pressure gaseous refrigerant passes through a compressor’s outlet and travels through a high-pressure lines to a condenser. The condenser is similar to a small radiator, and through a heat exchanging process with atmospheric air, the high temperature, high pressure gaseous refrigerant is liquefied. The liquefy refrigerant then flows into an expansion valve where it is restricted and becomes low temperature gaseous refrigerant. The low temperature gaseous refrigerant is now able to absorb heat from the air passing through an evaporator fins, leaving behind the cooler air 302. A cooled air fan may be used to blow the cool air 302 into the internal combustion engine’s engine air intake 202 through the second end 1062 of the air output duct 106. In certain embodiments, air density of the cooled air 302 from the air cooling chamber 104 is increased due to a cooling process inside the air cooling chamber assembly 100.

The second end 10822 of the gaseous refrigerant tube 1082 is connected to a low pressure line 4065 and further connected to an input 4061 of a compressor 406 of the standalone cooling device 400.

The standalone cooling device 400 is turned on when the control unit 402 detects from an ignition circuit 600 of the internal combustion engine 200 that an ignition of the internal combustion engine 200 is on.

In certain embodiments, the compressor 406 compresses the gaseous refrigerant resides in the standalone cooling device 400 into a high temperature and high pressure gaseous refrigerant.

The DC fan 403 is powered and controlled by a third power output line 4023 and a fourth power output line 4024 of the control unit 402.

In certain embodiments, the receiver dryer 408 stores the liquefy refrigerant from the condenser 405 and delivers the liquefy refrigerant to the expansion valve 404 for lowering the pressure of the liquefy refrigerant to allow it to change from a liquid to gaseous. The first end 4041 of the expansion valve 404 is connected to the first end 10821 of the gaseous refrigerant tube 1082, and the second end 4042 of the expansion valve 404 is connected to the high pressure line 4066.

In certain embodiments, the high temperature and high pressure gaseous refrigerant passes into an input connector 4061 out of an output connector 4062 and travels through a high-pressure lines 4066 to the condenser 405. The condenser 405 is similar to a small radiator, and the high temperature and high pressure gaseous refrigerant is liquefied through a heat exchanging process with atmospheric air. The liquefy refrigerant then flows through a receiver dryer 408 and a high pressure line connector 4082 into a high pressure line 4066 to the expansion valve 404. The liquefy refrigerant is restricted and becomes low temperature gaseous refrigerant. The low temperature gaseous refrigerant then travels through the tubing into the evaporator 108. The low temperature gaseous refrigerant flows through the finned-tube 1084 and returns to a low pressure inlet 4061 of the compressor 406 via the second end 10822 of the gaseous refrigerant tube 1082 of the evaporator 108.

The gaseous refrigerant flowing back to the compressor 406 will be compressed back into the high-pressure and high temperature gaseous refrigerant and the cooling process repeats. While cold gaseous refrigerant passes through the finned-tube 1082 of the evaporator 108, and through a heat exchange process, it lowers the temperature of the intake ambient air 301 that sucked in through the first end 1021 of the air intake duct 102, passes the finned-tube 1084.

The cooled air 302 becomes high density air, and the high density air carries increased amount of oxygen molecules. The high density cooled air 302 is then directed to an air- filter unit 204 through the air output duct 106 before providing this high density cooled air 302 to the internal combustion engine 200.

In certain embodiments, the air output duct 106 connecting the air cooling chamber assembly 100 to the air filter 204 is shielded by one or more thermal shield materials to shield the heat from the internal combustion engine 200 and maintain low temperature of the cooled air 302 in an engine compartment of the internal combustion engine 200. In certain embodiments, the thermal shield materials include thermal sleeving, thermal barriers, and/or thermal wraps. In other embodiments, the thermal shield materials include solid steel heat shield, aluminum heat shield, and/or ceramic thermal barrier coated heat insulation materials. These thermal shield materials are very important, and the air cooling chamber assembly 100 may not work properly without these thermal shield materials.

In certain embodiments, air density of the cooled air 302 from the air cooling chamber 104 is increased due to a cooling process inside the air cooling chamber assembly 100. High density cooled air 302 from the air cooling chamber 104 contains increased amount of oxygen molecules, and the increased amount of oxygen molecules in the high density cooled air 302 improves the fuel efficiency and reduces greenhouse gas emission of the internal combustion engine 200 of the automobile.
