All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terminology used in the embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one relationship describing the association of the associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
Referring to fig. 1 to 3, the present invention proposes an engine apparatus 100, the engine apparatus 100 including an engine 10, a supercharger 20, a first gas-liquid separation member 30, a second gas-liquid separation member 40, and an intercooler 50, the supercharger 20 being connected to the engine 10; a first end of the intercooler 50 is connected to the supercharger 20, a second end of the intercooler 50 is connected to a first end of the first gas-liquid separation member 30, and a second end of the first gas-liquid separation member 30 is connected to the engine 10; the second end of the first gas-liquid separation member 30 is also connected to the supercharger 20 via a second gas-liquid separation member 40.
The engine 10 is a device for providing power for an automobile, and after the engine 10 adopts an exhaust gas turbocharging technology, fuel can be completely combusted, so that the generation amount of CO and HC can be reduced; the power of engine 10 may also be increased using turbo charging techniques. Because of heat exchange with the housing 31 of the supercharger 20 and compression work of the supercharger 20 on air, the temperature of the air after passing through the supercharger 20 increases sharply, the density of the air decreases with an increase in temperature, and if the high-temperature air after passing through the supercharger 20 is not cooled, the mass of the air entering the engine 10 decreases with a decrease in the density of the air, so that the intake air amount decreases so that the power of the engine 10 decreases.
By providing the intercooler 50, the temperature of the pressurized gas can be reduced, thereby increasing the air density and thus the intake air amount; the intercooler 50 is located between the turbocharger 20 and the air inlet of the engine 10 and mainly comprises air chambers, main plates, cooling pipes, heat dissipation belts, turbulence plates and other parts, which can reduce the charge air temperature of the charge air and improve the charge air density, thereby improving the power per unit volume of the engine 10, reducing the fuel consumption and the emission of harmful substances and the like. The intercooler 50 may be classified into an air-to-air intercooler and a water-to-air intercooler according to the cooling medium; according to the different core structures, the air-to-air intercooler is further divided into a pipe-belt type intercooler, a plate-tilted intercooler, a laminated intercooler and the like.
During the time that the charge air temperature of the intercooler 50 is reduced, the Exhaust Gas in the Exhaust Gas Recirculation (EGR) system and the water vapor contained in the air are condensed into liquid water with the reduction of the temperature, and if the liquid water is not treated, the liquid water directly enters the engine 10 with the air flow, thereby affecting the combustion of the engine 10.
In the related art, a drain spring is used to drain liquid water, but the structure is relatively complex, the manufacturing cost is relatively high, referring to fig. 1 to 3, the invention proposes a first gas-liquid separation component 30 and a second gas-liquid separation component 40, the temperature of the pressurized gas is rapidly reduced after passing through an intercooler 50, so as to form a gas-liquid mixture, the gas-liquid mixture is conveyed to the first gas-liquid separation component 30 through a pipeline, and the density of the liquid condensed water is far greater than that of the gas, so that the condensed water can hit the shell 31 of the first gas-liquid separation component 30 along with inertia and fall into a water storage cavity 315 along with gravity, and the gas flows out of the pipeline and enters a throttle valve of an engine 10, thereby achieving the purpose of separating the gas and the condensed water.
When the automobile is in the condition of quick throttle release, the intercooler 50 and the first gas-liquid separation part 30 are required to release pressure, at the moment, condensed water stored in the first gas-liquid separation part is conveyed to the second gas-liquid separation part 40 through a pipeline, and then the condensed water is discharged through the second gas-liquid separation part 40, so that the purposes of separating gas and condensed water and releasing pressure are achieved, the condensed water is prevented from being sucked into a combustion chamber of the engine 10 to affect combustion, and the engine 10 can keep stable operation.
For convenience of description, when the first and second intercooler air outlet pipes are mentioned at the same time, the two intercooler air outlet pipes will be replaced, and the remaining description may refer to the above.
Referring to fig. 1 and 2, in an embodiment of the present invention, the engine apparatus 100 further includes a first intercooler air outlet pipe 53, a second intercooler air outlet pipe 55, and a first pressure relief pipe 61, the first gas-liquid separation part 30 includes a housing 31, a first connection pipe 33, and a second connection pipe 35, and a water storage cavity 315 is formed in the housing 31; the first connecting pipe 33 is connected to the first end of the housing 31 and is located in the water storage cavity 315; the first connecting pipe 33 is connected with one end of a first intercooler air outlet pipe 53, and the other end of the first intercooler air outlet pipe 53 is connected with the second end of the intercooler 50; the second connecting pipe 35 is positioned at the second end of the shell 31 and is connected with a second intercooler air outlet pipe 55; the other end of the second intercooler outlet pipe 55 is connected to the engine 10, one end of the first pressure relief pipe 61 is connected to the second end of the housing 31 and extends into the water storage cavity 315, and the other end of the first pressure relief pipe 61 is connected to the second gas-liquid separation part 40.
The first intercooler outlet pipe 53 and the first pressure relief pipe 61 function to transport the gas-liquid mixture, and the second intercooler outlet pipe 55 functions to transport and condense the water-separated gas.
In the present embodiment, the housing 31 is used to provide an installation space for the two connection pipes, and the water storage chamber 315 is used to store condensed water to prevent it from leaking out; the first connecting pipe 33 is used for connecting the first intercooler air outlet pipe 53 to transport the gas-liquid mixture passing through the intercooler 50, the second connecting pipe 35 is used for connecting the second intercooler air outlet pipe 55 to convey the gas after gas-liquid separation to the throttle valve of the engine 10 through the second intercooler air outlet pipe 55, and the gas and oil system are mixed for combustion so as to keep the engine 10 working normally.
It can be appreciated that the first connecting pipe 33 and the first intercooler air outlet pipe 53 may be connected by a flange, so that the disassembly and the maintenance are convenient, and the disassembly and the maintenance are time-saving, meanwhile, the connection between the first connecting pipe 33 and the housing 31 may be more stable, although other detachable connection modes may be adopted between the first connecting pipe 33 and the first intercooler air outlet pipe 53, or welding or other connection modes capable of keeping stability of the two may be adopted, which are not limited herein, and the connection between other pipelines in the present invention may refer to the connection mode between the first connecting pipe 33 and the first intercooler air outlet pipe 53, which is not repeated herein.
The first pressure relief pipe 61 extends into the water storage cavity 315, preferably, a gap exists between the first pressure relief pipe and the first end of the housing 31, and condensed water is more conveniently sucked up when the regulating valve is opened, so that water absorption and transportation efficiency are improved, and meanwhile, blockage can be avoided, so that cleaning is facilitated.
Referring to fig. 1 and 2, in an embodiment of the present invention, further, the housing 31 includes a vertical portion 311 and a bending portion 313, the vertical portion 311 is disposed to extend along a first direction, and the bending portion 313 is connected to the vertical portion 311 in a bending manner; a water storage cavity 315 is formed in the vertical part 311, the first connecting pipe 33 is connected with the vertical part 311, and the second connecting pipe 35 is connected with the bending part 313; the first pressure relief pipe 61 is connected with the bending part 313 and extends into the water storage cavity 315; one end of the second intercooler outlet pipe 55 is connected to the bending portion 313.
In the present embodiment, the vertical portion 311 is disposed along the first direction, that is, along the height direction of the engine 10, the bending portion 313 is bent and connected to the vertical portion 311, so that the gas-liquid mixture enters the housing 31 and moves along the first direction, and the liquid condensed water is driven to the bending portion 313 along with the inertial movement due to the fast moving speed of the gas-liquid mixture and the density of the liquid condensed water is much higher than that of the gas, and falls into the water storage cavity 315 under the action of gravity, thereby completing the first gas-liquid separation.
The first connecting pipe 33 is connected to the vertical portion 311, the second connecting pipe 35 is connected to the bent portion 313, and the two connecting pipes are staggered and not all arranged along the first direction, in order to prevent condensed water from entering the second connecting pipe 35 along with inertia, so that the condensed water does not enter the combustion chamber of the engine 10.
The shape of the first pressure relief tube 61 may also be configured to correspond to the shape of the vertical portion 311 and the bent portion 313, so that the connection between the first pressure relief tube 61 and the housing 31 reduces friction and is more stable.
Referring to fig. 1 to 3, in an embodiment of the present invention, the second gas-liquid separation part 40 includes a water storage part 41, a water storage part air inlet pipe 43 and a water storage part air outlet pipe 45, and a water storage cavity 47 is formed in the water storage part 41; one end of the water storage part air inlet pipe 43 is connected with the first end of the water storage part 41 and extends into the water storage cavity 47; the other end of the reservoir air inlet pipe 43 is connected with a first pressure relief pipe 61; the water storage piece air outlet pipe 45 is arranged at intervals with the water storage piece air inlet pipe 43, one end of the water storage piece air outlet pipe 45 is connected with the water storage piece 41 and extends into the water storage cavity 47, and the other end is connected with the supercharger 20.
In this embodiment, the water storage member 41 is used for providing support for the water storage member air inlet pipe 43 and the water storage member air outlet pipe 45, and discharging condensed water, the water storage member air inlet pipe 43 is used for connecting the first pressure relief pipe 61, conveying the condensed water in the water storage cavity 315 transported by the first pressure relief pipe 61 into the water storage cavity 47, and the water storage member air outlet pipe 45 is used for conveying the secondarily separated gas to the supercharger 20, and entering the combustion chamber of the engine 10 after being supercharged by the supercharger 20.
When the engine 10 works, the gas is pressurized by the supercharger 20, the gas enters the engine 10 in a high-pressure state, wherein the whole air inlet channel is internally provided with a high-pressure end and a low-pressure end, an air filter 70 positioned in front of the supercharger 20 is provided with a low-pressure end, and a second pressure relief part 65, a water storage piece 41 and a second pressure relief pipe 67 which are communicated with the air filter 70 are also provided with a low-pressure end; the intercooler air inlet pipe 51, the intercooler 50, the first intercooler air outlet pipe 53, the first gas-liquid separation part 30 and the second intercooler air outlet pipe 55 after the supercharger 20 are at high pressure end, and the first pressure relief portion 63 is in communication with the second intercooler air outlet pipe 55, and the air release valve is in a closed state under most working conditions when the engine 10 is running, so the first pressure relief portion 63 is also at high pressure end.
When the automobile is in the quick throttle condition, the throttle valve of the engine 10 is closed suddenly, at the moment, the air inflow of high-pressure air entering the engine 10 through the throttle valve is reduced, the supercharger 20 still works under the action of inertia to continuously supercharge the air, and the pressure in the whole high-pressure channel is increased sharply due to the fact that the amount of the entering air is large and the amount of the exiting air is small. When the internal pressure exceeds the set value in the high pressure passage, the electronic control system of the engine 10 controls the opening of the pressure release valve 60 so that the gas in the high pressure passage flows from the high pressure end to the low pressure end, thereby achieving the purpose of releasing the pressure for the high pressure passage.
At this time, the gas in the high pressure channel (including the intercooler air inlet pipe 51, the intercooler 50, the first intercooler air outlet pipe 53, the first gas-liquid separation component 30, the second intercooler air outlet pipe 55, and the first pressure relief portion 63) flows to the low pressure channel (including the second pressure relief portion 65, the water storage piece 41, the second air relief pipe, and the air filter 70) through the pressure relief valve 60, if the liquid surface of the condensed water accumulated in the water storage cavity 315 floods the first pressure relief pipe 61 to extend into one end of the water storage cavity 315, the condensed water accumulated in the water storage cavity 315 will be discharged into the water storage cavity 47 through the first pressure relief pipe 61, and at this time, the gas and the condensed water still have the gas separated by the first gas-liquid separation component 30 in the first pressure relief pipe 61 again form a gas-liquid mixture, at this time, because the density of the liquid condensed water is far greater than that of the gas, the gas will rise upward, and the condensed water falls to the second end of the water storage piece 41 under the action of gravity, so that the gas and the condensed water can be separated again.
Referring to fig. 1 to 3, in an embodiment of the present invention, further, the height of the water storage member air inlet pipe 43 extending into the water storage chamber 47 in the first direction is greater than the height of the water storage member air outlet pipe 45 extending into the water storage chamber 47 in the first direction.
