Description

Technical Field

[0001] This application relates to the field of engine technology, and more specifically, to an engine and a vehicle. Background Technology

[0002] In existing engines, the intake manifold needs to work in conjunction with the fuel injection system to ensure that fuel (e.g., gasoline, diesel, etc.) and air can be fully mixed before entering the engine's combustion chamber, thereby improving the engine's combustion efficiency.

[0003] However, during engine operation, an oil film easily forms on the inner wall of the intake manifold. During the piston's reciprocating motion, this oil film enters the crankcase, diluting the lubricating oil. This diluted lubricating oil then easily enters the combustion chamber, inducing pre-ignition and severely impacting the engine's output performance. Utility Model Content

[0004] This application provides an engine and a vehicle.

[0005] According to a first aspect of this application, an embodiment of this application provides an engine, which includes a cylinder block, an intake manifold, and a microwave module. The cylinder block has a combustion chamber; the intake manifold is connected to the cylinder block and communicates with the combustion chamber, and has a microwave action area; the microwave module has a microwave transmitter disposed within the intake manifold and is used to generate microwaves within the microwave action area.

[0006] In some possible embodiments, the microwave module includes a microwave generator and a microwave conductor connected together, and the microwave conductor is provided with a microwave transmitting end; the microwave conductor is used to conduct the microwaves generated by the microwave generator into the air intake.

[0007] In some possible embodiments, the inner wall of the air intake is provided with a microwave reflective layer that extends along the length of the air intake and the area surrounded by the microwave reflective layer defines the microwave action area.

[0008] In some possible embodiments, the air intake has an opposing air inlet and an air outlet, with the air outlet connected to the cylinder block; one end of the microwave reflector extends to the air outlet, and the other end of the microwave reflector has a gap with the air inlet.

[0009] In some possible embodiments, the microwave reflective layer is a noble metal coating or a metal reflective sheet.

[0010] In some possible embodiments, the engine further includes a control module and a temperature detection module. The control module is electrically connected to the microwave module and is used to control the microwave module to output microwaves to the air intake. The temperature detection module is provided with a temperature detection end, which is located within the microwave action area. The control module and the temperature detection module are electrically connected.

[0011] In some possible embodiments, the control module includes a signal receiving circuit, a controller, and a signal output circuit. The signal receiving circuit is connected between the temperature detection module and the controller to receive the temperature signal detected by the temperature detection module. The signal output circuit is connected between the controller and the microwave module to output a control signal to the microwave module, which is used to adjust the output power of the microwave module.

[0012] In some possible embodiments, the air intake is provided with an air outlet, which is connected to the cylinder block; the distance between the temperature detection end and the air outlet is less than the distance between the microwave transmitter and the air outlet.

[0013] In some possible embodiments, the engine further includes a fuel injection module with an injection end positioned within the microwave action area; an air intake is provided with an air outlet connected to the cylinder block; the distance between the microwave transmitter and the air outlet is less than the distance between the injection end and the air outlet.

[0014] According to a second aspect of this application, an embodiment of this application also provides a vehicle, the vehicle including a housing and the aforementioned engine, the engine being disposed within the housing.

[0015] This application provides an engine and a vehicle. The engine includes a cylinder block, an intake manifold, and a microwave module. The intake manifold is connected to the combustion chamber of the cylinder block and has a microwave action area. The microwave transmitter of the microwave module is disposed in the intake manifold and is used to generate microwaves in the microwave action area.

[0016] Therefore, the engine in this application is equipped with a microwave module, which enables the microwaves generated to act on the microwave action area of ​​the intake manifold. This allows the microwaves to heat the air in the intake manifold, thereby causing the oil film adsorbed in the intake manifold to evaporate rapidly. This reduces the chance of the lubricating oil being diluted, preventing diluted lubricating oil from entering the combustion chamber and inducing pre-ignition, thus ensuring that the engine has good output performance.

[0017] In addition, when the engine is operating in a low-temperature environment, heating the air by radiating microwaves inside the intake manifold can quickly alleviate the icing situation in the intake manifold, thereby improving the engine's starting and operating reliability in low-temperature environments.

For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0023] Please see Figure 1 This application provides an engine 100 and a vehicle 200 equipped with the engine 100. The vehicle 200 refers to a means of transportation driven or towed by a power device for the purpose of carrying people or transporting goods, including but not limited to cars, suburban utility vehicles (SUVs), multi-purpose vehicles (MPVs), driverless ride-hailing vehicles, minibuses, buses, etc.

[0024] In this embodiment, the vehicle 200 may include a housing 210 and an engine 100. The engine 100 is disposed within the housing 210 and provides power for the movement of the vehicle 200. Specifically, the engine 100 in this embodiment may be a reciprocating piston engine. The reciprocating piston engine primarily generates power by burning fuel (e.g., gasoline or diesel) to drive piston movement, which in turn drives the crankshaft to rotate, thus providing power to the vehicle 200.

[0025] Please see Figure 2The engine 100 may include a cylinder block 30, an intake manifold 40, and a microwave module 50. The cylinder block 30 has a combustion chamber 320. The intake manifold 40 is connected to the cylinder block 30 and communicates with the combustion chamber 320. In this embodiment, the intake manifold 40 has a microwave action region B. The microwave module 50 has a microwave transmitter 501, which is disposed within the intake manifold 40 and used to generate microwaves within the microwave action region B.

[0026] Therefore, in this embodiment, the engine 100 is equipped with a microwave module 50, which enables the microwaves generated by the module to act on the microwave action area B of the intake duct 40. This allows the microwaves to heat the air inside the intake duct 40, thereby causing the oil film adsorbed inside the intake duct to evaporate rapidly. This reduces the probability of the lubricating oil being diluted and prevents diluted lubricating oil from entering the combustion chamber 320 and inducing pre-ignition, thus ensuring that the engine 100 has good output performance.

[0027] Furthermore, when the engine 100 operates in a low-temperature environment, heating the air by radiating microwaves within the intake duct 40 can quickly alleviate the icing situation in the intake duct, thereby improving the starting and operating reliability of the engine 100 in low-temperature environments.

[0028] The specific structure of engine 100 is described below.

[0029] In this embodiment, the cylinder block 30 is generally cylindrical, and a piston (not shown in the figure) is installed inside it, forming a sealed cavity (i.e., combustion chamber 320) together with the piston. Specifically, during the intake stroke of the engine 100, the intake valve 450, located between the intake manifold 40 and the cylinder block 30, opens, and the exhaust valve (not shown in the figure) closes. The downward movement of the piston in the engine 100 creates a negative pressure in the combustion chamber 320, thereby drawing outside air into the combustion chamber 320 through the intake manifold 40, providing sufficient oxygen for the subsequent combustion process.

[0030] In this embodiment, the intake duct 40 has an intake port 420 and an exhaust port 430, wherein the exhaust port 430 is connected to the cylinder block 30 and communicates with the combustion chamber 320. Specifically, the end of the intake duct 40 with the exhaust port 430 can be fixed to the cylinder block 30 by welding. The intake port 420 is connected to the outside, so that outside air can smoothly enter the combustion chamber 320 through the intake duct 40.

[0031] In this embodiment, the air intake duct 40 is provided with a microwave action area B. The microwave action area B can be defined by the target area acted upon by the microwave transmitter 501. It may or may not have a clear boundary. For example, a specific physical material can be used to define a relatively well-defined area. Exemplarily, the "microwave action area B" can be the entire space within the air intake duct 40, or it can be a portion of the space within the air intake duct 40 (for example, the space within the air intake duct 40 near the combustion chamber 320). Specifically, the microwave action area B is "filled" with microwaves under the action of the microwave module 50, thereby heating the air within the microwave action area B.

[0032] In some possible embodiments, the air intake 40 may be made of a metallic material (e.g., aluminum alloy, stainless steel, etc.) to improve the heat resistance of the engine 100. In this case, since the metallic material has good microwave reflectivity, the entire space within the air intake 40 can be considered as the microwave stimulating region B, thereby achieving sufficient heating of the air.

[0033] In other possible embodiments, the air intake duct 40 may be made of a plastic material (e.g., glass fiber reinforced nylon, PPA resin) or a rubber material, which is beneficial for achieving a lightweight design of the engine 100. In this case, the inner wall of the air intake duct 40 may be provided with a microwave reflective layer 410, which extends along the length of the air intake duct 40, and the area surrounded by the microwave reflective layer 410 defines the microwave activating region B. Specifically, the microwave reflective layer 410 may be a noble metal coating (e.g., a platinum metal coating, a palladium metal coating, a rhodium metal coating, etc.) or a metal reflective sheet.

[0034] Therefore, in this embodiment, by providing a microwave reflective layer 410 on the inner wall of the air intake duct 40, the microwave energy of the air intake duct 40 can be reflected and dispersed to ensure that the microwave energy can be evenly distributed within the air intake duct 40, thereby achieving uniform and sufficient heating of the air. Specifically, the microwave reflective layer 410 transmits and reflects the microwave energy generated by the microwave module 50, allowing the air within the air intake duct 40 to absorb the microwave energy and convert it into heat energy. Since microwaves can penetrate gas molecules and interact directly with them, the air heating process is very fast and efficient. Furthermore, microwave energy can directly act on gas and oil film molecules, causing them to vibrate and rotate, thereby generating heat energy to increase the temperature of the gas and oil film and accelerate the evaporation rate of the oil film.

[0035] In some possible embodiments, one end of the microwave reflector layer 410 extends to the air outlet 430, and the other end of the microwave reflector layer 410 has a gap with the air inlet 420. That is, in this embodiment, the microwave reflector layer 410 is only provided in a part of the air intake duct 40 (i.e., the area near the combustion chamber 320) to shorten the overall length of the microwave reflector layer 410 and reduce the hardware cost of the air intake duct 40. It is easy to understand that since the microwave reflector layer 410 is provided in the area near the combustion chamber 320, the microwaves can fully heat the air about to enter the combustion chamber 320 to quickly evaporate part of the oil film adsorbed in the corresponding area of ​​the air intake duct, thus preventing diluted lubricating oil from entering the combustion chamber 320 and inducing pre-ignition.

[0036] In this embodiment, the microwave module 50 may include a microwave generator 520 and a microwave conductor 540 connected to each other. The microwave conductor 540 is provided with a microwave transmitting end 501. The microwave generator 520 is used to generate microwave energy and can be located outside the air intake duct 40, transmitting microwaves into the air intake duct 40 via the microwave conductor 540. Specifically, the microwave generator 520 can be an electrovacuum microwave generator (e.g., a magnetron, klystron, etc.) or a semiconductor microwave generator (e.g., a solid-state microwave source). The microwave frequency of the microwave generator 520 can be between 300MHz and 300GHz. The microwave conductor 540 can be a waveguide, coaxial cable, or other transmission medium. This embodiment does not limit the specific implementation of the microwave generator 520 and the microwave conductor 540.

[0037] Therefore, in this embodiment, the microwave conductor 540 can ensure that microwave energy is efficiently and losslessly transmitted from the microwave generator 520 to the interior of the air intake 40, thereby ensuring the efficiency of microwave energy utilization.

[0038] Please see Figure 3 In some possible embodiments, the engine 100 may further include a control module 60 and a temperature detection module 70. The control module 60 is electrically connected to the microwave module 50 and is used to control the microwave module 50 to output microwaves to the intake duct 40. For example, the control module 60 may control the microwave module 50 to turn on when the engine 100 is in the intake stroke, so as to radiate microwaves into the intake duct 40.

[0039] The control module 60 and the temperature detection module 70 are electrically connected. The temperature detection module 70 is provided with a temperature detection end 702, which is located within the microwave action area B to detect the temperature within the microwave action area B. Specifically, the temperature detection module 70 can be a temperature sensor, such as a thermocouple temperature sensor, a resistance temperature sensor, a semiconductor temperature sensor, etc.

[0040] In some possible embodiments, the control module 60 may include a signal receiving circuit 610, a controller 630, and a signal output circuit 650. The signal receiving circuit 610 is connected between the temperature detection module 70 and the controller 630, and is used to receive the temperature signal detected by the temperature detection module 70. The signal output circuit 650 is connected between the controller 630 and the microwave module 50, and is used to output a control signal to the microwave module 50. The control signal is used to adjust the output power of the microwave module 50. Specifically, the controller 630 may be an integrated chip, a microcontroller unit (MCU), etc. This embodiment does not limit the implementation of the signal receiving circuit 610, the controller 630, and the signal output circuit 650.

[0041] In this embodiment, the control module 60 can perform closed-loop control of the output power of the microwave module 50 based on the temperature signal detected by the temperature detection module 70, so that the temperature within the microwave action area B can be maintained within a fixed temperature range. Specifically, when the temperature within the microwave action area B is greater than the upper limit of the temperature range, the control module 60 can reduce the output power of the microwave module 50; conversely, when the temperature within the microwave action area B is less than the lower limit of the temperature range, the control module 60 can increase the output power of the microwave module 50. Specifically, the control module 60 can store control algorithms (e.g., PID algorithm, fuzzy control algorithm) to flexibly adjust the output power of the microwave module 50, so as to avoid overheating or underheating in the intake duct 40, thereby ensuring the stability and efficiency of the heating process, improving the working efficiency and low-temperature start-up performance of the engine 100.

[0042] In some possible embodiments, the distance between the temperature detection end 702 and the air outlet 430 is less than the distance between the microwave transmitter 501 and the air outlet 430. That is, the temperature detection end 702 is positioned between the microwave transmitter 501 and the air outlet 430 so that the temperature signal detected by the temperature detection module 70 can accurately reflect the air temperature after being heated by microwaves, making subsequent adjustments to the output power of the microwave module 50 more precise and efficient.

[0043] In some possible embodiments, the engine 100 may further include a fuel injection module 80, which may be connected to a fuel tank (i.e., fuel tank) within the vehicle 200 to supply fuel to the engine 100. Specifically, the fuel injection module 80 may be a nozzle, which may have an injection end 801 disposed within the microwave action area B. The distance between the microwave emitting end 501 and the air outlet 430 is less than the distance between the injection end 801 and the air outlet 430. That is, the microwave emitting end 501 is disposed between the injection end 801 and the air outlet 430. Therefore, the fuel injected through the injection end 801 is heated by microwaves within the intake duct 40 before entering the combustion chamber 320, thereby improving the combustion efficiency of the subsequent fuel.

[0044] This application provides an engine 100 and a vehicle 200 equipped with the engine 100. The engine 100 may include a cylinder block 30, an intake manifold 40, and a microwave module 50. The cylinder block 30 has a combustion chamber 320. The intake manifold 40 is connected to the cylinder block 30 and communicates with the combustion chamber 320. In this embodiment, the intake manifold 40 has a microwave action region B. The microwave module 50 has a microwave transmitter 501, which is disposed within the intake manifold 40 and used to generate microwaves within the microwave action region B.

[0045] Therefore, in this embodiment, the engine 100 is equipped with a microwave module 50, which enables the microwaves generated by the module to act on the microwave action area B of the intake duct 40. This allows the microwaves to heat the air inside the intake duct 40, thereby causing the oil film adsorbed inside the intake duct to evaporate rapidly. This reduces the probability of the lubricating oil being diluted and prevents diluted lubricating oil from entering the combustion chamber 320 and inducing pre-ignition, thus ensuring that the engine 100 has good output performance.

[0046] Furthermore, when the engine 100 operates in a low-temperature environment, heating the air by radiating microwaves within the intake duct 40 can quickly alleviate the icing situation in the intake duct, thereby improving the starting and operating reliability of the engine 100 in low-temperature environments.
