[0065] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0066] To achieve the above objectives, according to the first aspect of this application, a vehicle is provided, in conjunction with Figure 1-2 It can be seen that the vehicles include:
[0067] Body 3, body 3 has a front compartment 31;
[0068] Engine 1 is located in the forward compartment 31 and has an exhaust port 11.
[0069] Exhaust system 2 is located in the front compartment 31 and is connected to exhaust port 11. It is capable of handling the gas discharged from engine 1.
[0070] By centrally mounting the engine 1 and exhaust system 2 in the front compartment 31, thermal management is more convenient, which is beneficial for vehicle heat dissipation optimization and heat recovery. In addition, the centralized layout of the engine 1 and exhaust system 2 also makes vehicle maintenance more convenient.
[0071] For example, the vehicle can be defined as three main parts from a top-down view: the front compartment 31, the middle floor, and the rear floor.
[0072] Among them, the front compartment 31 consists of all body floor components 3 up to the front bulkhead of the vehicle on the driver's side.
[0073] The rear floor is defined as the floor component on the upper side of the vehicle's rear frame.
[0074] The middle floor is defined as the body floor component between the front compartment 31 and the rear floor;
[0075] In some embodiments, the exhaust system 2 includes:
[0076] Catalytic converter 21 is located in the front compartment 31 and is capable of purifying the gas discharged from engine 1.
[0077] The muffler 22 is located in the front compartment 31 and can reduce the noise intensity of the exhaust gas from the engine 1.
[0078] The catalytic converter 21 and the muffler 22 are connected to the engine 1 in sequence, that is, one end of the catalytic converter 21 is connected to the engine 1, and the muffler 22 is connected to the other end of the catalytic converter 21.
[0079] When engine 1 is running, the exhaust gas can first be treated by the catalytic converter 21 to reduce harmful gas emissions, and then the noise can be reduced by the muffler 22 to achieve an environmentally friendly and comfortable driving experience. Since both the catalytic converter 21 and the muffler 22 are located in the front compartment 31, maintenance is more convenient.
[0080] In some embodiments, along the height direction of the vehicle, the exhaust port 11 is located above or below the engine 1; or, along the longitudinal direction of the vehicle, the exhaust port 11 is located in front of or behind the engine 1; or, along the lateral direction of the vehicle, the exhaust port 11 is located on the left or right side of the engine 1; and / or,
[0081] Along the height direction of the vehicle, the muffler 22 is located on the upper or lower side of the engine 1; or along the longitudinal direction of the vehicle, the muffler 22 is located on the front or rear side of the engine 1; or along the lateral direction of the vehicle, the muffler 22 is located on the left or right side.
[0082] The positions of the exhaust port 11 and the muffler 22 are more varied and can be selected according to specific design requirements, making them more applicable.
[0083] For example, along the longitudinal direction of the vehicle, the catalytic converter 21, the muffler 22, and the exhaust port 11 are all located on the front side of the engine 1.
[0084] In some embodiments, the silencing device 22 includes a silencing unit and a first housing 221, both of which are disposed within the first housing 221.
[0085] The integrated design, in which both the muffler unit and the catalytic converter 21 are housed within the first housing 221, facilitates the assembly of the exhaust system 2 in the front compartment 31. Specifically, the muffler unit can be an existing vehicle muffler structure.
[0086] In some embodiments, combined with Figure 3 The exhaust system 2 also includes a connecting channel 214. The catalytic converter 21 includes a first carrier unit 211 and a second carrier unit 212. The first carrier unit 211 is connected to the exhaust port 11 and can purify the gas discharged from the engine 1. The second carrier unit 212 is connected to the first carrier unit 211 through the connecting channel 214 and can purify the gas transmitted by the first carrier unit 211. The muffler 22 is connected to the second carrier unit 212.
[0087] The first carrier unit 211 and the second carrier unit 212 can sequentially purify the exhaust gas discharged from the engine 1 to reduce the emission of harmful gases; and the two are connected by the connecting channel 214 and can be installed separately, making the position arrangement of the first carrier unit 211 and the second carrier unit 212 more flexible and convenient.
[0088] For example, the first carrier unit 211 and / or the second carrier unit 212 may have a white carrier and a coating of noble metal, wherein the noble metal is coated on the white carrier, the white carrier may be a ceramic material, and the noble metal may be a common material in exhaust gas catalysis such as platinum, palladium, rhodium (Pt / Pd / Rh).
[0089] For example, the exhaust system 2 is installed in the front compartment 31, with the front side not exceeding the radiator 4, the rear side not exceeding the flywheel housing of the engine 1, the left side not exceeding the left longitudinal beam of the vehicle body 3, and the right side not exceeding the right longitudinal beam of the vehicle body 3. The arrangement of the exhaust system 2 can ensure a large gap between the front side of the engine 1 and the electric drive assembly and the rear side of the radiator 4, which can ensure the arrangement space of the integrated muffler system.
[0090] In some embodiments, the first carrier unit 211 has a three-way catalytic converter and / or a gasoline particulate filter; and / or,
[0091] The second carrier unit 212 has a three-way catalytic converter and / or a gasoline particulate filter.
[0092] The structural designs for the specific waste gas treatment of the first carrier unit 211 and the second carrier unit 212 are more diverse and can be selected according to specific design requirements, making them more applicable.
[0093] For example, the catalytic form of the combination of the first support unit 211 and the second support unit 212 can be one or more of TWC+TWC, TWC+GPF, TWC+TWC+GPF, TWC+GPF+TWC+GPF, TWC+TWC+GPF+TWC+GPF, and TWC+TWC+TWC+TWC, or TWC+TWC+GPF+TWC+TWC+GPF.
[0094] In some embodiments, along the height direction of the vehicle, the first carrier unit 211 is located above or below the engine 1; or, along the longitudinal direction of the vehicle, the first carrier unit 211 is located in front of or behind the engine 1; or, along the lateral direction of the vehicle, the first carrier unit 211 is located on the left or right side of the engine 1; and / or,
[0095] Along the height direction of the vehicle, the second carrier unit 212 is located on the upper or lower side of the engine 1; or along the longitudinal direction of the vehicle, the second carrier unit 212 is located on the front or rear side of the engine 1; or along the lateral direction of the vehicle, the second carrier unit 212 is located on the left or right side of the engine 1.
[0096] The positions of the first carrier unit 211 and the second carrier unit 212 are more varied and can be selected according to specific design requirements, making them more applicable.
[0097] In some embodiments, the silencing device 22 includes a silencing unit and a first housing 221. The silencing unit and the second carrier unit 212 are both disposed inside the first housing 221, and the first carrier unit 211 is disposed outside the first housing 221.
[0098] The integrated design of the silencing unit and the second carrier unit 212 both being located within the first housing 221 facilitates the assembly of the exhaust system 2 at the front compartment 31.
[0099] In some embodiments, combined with Figure 3 It can be seen that there are multiple connecting channels 214, multiple second carrier units 212, and multiple silencing devices 22. The multiple silencing devices 22 are connected to multiple second carrier units 212 respectively, and the multiple second carrier units 212 are connected to the first carrier unit 211 through multiple connecting channels 214 respectively.
[0100] The combination of multiple connecting channels 214, multiple second carrier units 212 and multiple mufflers 22 can divert exhaust gas flow, avoid overload of a single passage, and significantly reduce the total back pressure. As a result, when the engine 1 is running at high load or high speed, the exhaust system 2 can also smoothly discharge exhaust gas.
[0101] In some embodiments, along the height direction of the vehicle, a plurality of second carrier units 212 are located above and / or below the engine 1; and / or,
[0102] Along the longitudinal direction of the vehicle, multiple second carrier units 212 are located on the front and / or rear side of the engine 1; and / or,
[0103] Along the lateral direction of the vehicle, multiple second carrier units 212 are located on the left and / or right side of the engine 1; and / or,
[0104] Along the height direction of the vehicle, multiple mufflers 22 are located above and / or below the engine 1; and / or,
[0105] Along the longitudinal direction of the vehicle, multiple mufflers 22 are located on the front and / or rear side of the engine 1; and / or,
[0106] Along the lateral direction of the vehicle, multiple mufflers 22 are located on the left and / or right side of the engine 1.
[0107] The placement of multiple silencing devices 22 and multiple second carrier units 212 is more diverse and can be selected according to specific design requirements, making it more applicable.
[0108] For example, there are two second carrier units 212, two connecting channels 214, and two mufflers 22. Along the lateral direction of the vehicle, the two mufflers 22 are located on the left and right sides of the engine 1, respectively. The two second carrier units 212 are located on the left and right sides of the engine 1, respectively. Along the longitudinal direction of the vehicle, the first carrier unit 211 is located on the front side of the engine 1.
[0109] In some embodiments, combined with Figure 4 and Figure 6It can be seen that there are multiple first carrier units 211 and multiple exhaust ports 11. The multiple exhaust ports 11 are respectively connected to multiple first carrier units 211. The multiple first carrier units 211 are respectively connected to one end of multiple connecting channels 214. The other end of the multiple connecting channels 214 are respectively connected to multiple second carrier units 212.
[0110] The coordination of multiple exhaust ports 11, multiple first carrier units 211, multiple connecting channels 214, multiple second carrier units 212, and multiple mufflers 22 forms a multi-path exhaust system. This system can divert exhaust gas flow, prevent overload of individual paths, and significantly reduce overall back pressure. Consequently, even when the engine 1 is running under high load or at high speed, the exhaust system 2 can still smoothly discharge exhaust gas. Furthermore, each exhaust path can operate independently and be optimized for different operating conditions (such as low speed, high speed, cold start, etc.). The load distribution of each exhaust mechanism can also be adjusted according to actual needs (e.g., through regulating valves or sensors) to better adapt to changes in the engine 1.
[0111] In some embodiments, along the height direction of the vehicle, a plurality of first carrier units 211 are located above and / or below the engine 1.
[0112] Along the longitudinal direction of the vehicle, multiple first carrier units 211 are located on the front and / or rear side of the engine 1; and / or,
[0113] Along the lateral direction of the vehicle, multiple first carrier units 211 are located on the left and / or right side of the engine 1; and / or,
[0114] Along the height direction of the vehicle, multiple exhaust ports 11 are located above and / or below the engine 1; and / or,
[0115] Along the longitudinal direction of the vehicle, multiple exhaust ports 11 are located on the front and / or rear side of the engine 1; and / or,
[0116] Along the lateral direction of the vehicle, multiple exhaust ports 11 are located on the left and / or right side of the engine 1.
[0117] The multiple exhaust ports 11 and multiple second carrier units 212 can be positioned in a more diverse manner, and can be selected according to specific design requirements, making them more applicable.
[0118] For example, there are two exhaust ports 11, two first carrier units 211, two second carrier units 212, two connecting channels 214, and two mufflers 22. Along the vehicle's lateral direction, the two mufflers 22 are located on the left and right sides of the engine 1, respectively, and the two second carrier units 212 are located on the left and right sides of the engine 1, respectively. Along the vehicle's longitudinal direction, the two first carrier units 211 and the two exhaust ports 11 are located on the front side of the engine 1; or...
[0119] There are two exhaust ports 11, two first carrier units 211, two second carrier units 212, two connecting channels 214, and two mufflers 22. Along the lateral direction of the vehicle, the two mufflers 22 are located on the left and right sides of the engine 1, the two second carrier units 212 are located on the left and right sides of the engine 1, the two first carrier units 211 are located on the left and right sides of the engine 1, and the two exhaust ports 11 are located on the left and right sides of the engine 1.
[0120] In some embodiments, combined with Figure 5 It is known that the catalytic device 21 also includes a second housing 213, a plurality of first carrier units 211 are disposed inside the second housing 213, and a plurality of second carrier units 212 are disposed outside the second housing 213.
[0121] The integrated design of multiple first carrier units 211 being housed within the second housing 213 facilitates the assembly of the exhaust system 2 at the front compartment 31.
[0122] In some embodiments, engine 1 is a V-type engine; and / or,
[0123] Engine 1 is a multi-cylinder engine; and / or,
[0124] Engine 1 is one of the following: non-turbocharged engine, mechanical supercharged engine, electronic supercharged engine, and turbocharged engine.
[0125] The engine 1 offers multiple configuration options, allowing for selection based on specific design requirements and thus greater applicability.
[0126] For example, the multi-cylinder engine 1 can be one of a two-cylinder engine, a three-cylinder engine, a five-cylinder engine, a six-cylinder engine, an eight-cylinder engine, a ten-cylinder engine, and a twelve-cylinder engine.
[0127] In some embodiments, the generator serves as a power source for a vehicle that can be directly driven.
[0128] In some embodiments, the vehicle also includes a generator, the engine 1 being able to connect to the generator and drive the generator to generate electricity.
[0129] When engine 1 is running, it can drive the rotor of the generator to rotate at high speed. The stator coil inside the generator interacts with the magnetic field of the rotating rotor to generate an induced current, thereby converting the chemical energy of fuel into electrical energy and completing the power generation.
[0130] In some embodiments, the vehicle further includes a battery 5 disposed at the body 3, and the exhaust system 2 also has an exhaust port 23 for discharging exhaust gases, the exhaust port 23 being connected to a muffler 22 and located in front of the battery 5 along the longitudinal direction of the vehicle.
[0131] The exhaust port 23 is located on the front side of the battery 5, so as not to exceed the front end face of the battery 5, so as to avoid the exhaust pipe connected to the exhaust port 23 being arranged on both sides or in the middle of the battery 5, so as to prevent affecting the arrangement space of the battery 5.
[0132] Specifically, the exhaust port 23 is located in the front compartment 31, with the following boundaries: the front boundary does not exceed the front bumper of the vehicle, the rear boundary does not exceed the front face of the battery 5, the left boundary does not exceed the left wheel arch, the right boundary does not exceed the right wheel arch, the upper boundary does not exceed the vehicle hood, and the lower boundary does not exceed the vehicle's minimum ground clearance.
[0133] In some embodiments, the crankshaft of engine 1 can extend longitudinally along the vehicle.
[0134] The crankshaft can extend longitudinally along the vehicle to align with the vehicle's direction of travel, resulting in a more direct power transmission path, reduced energy loss, and improved transmission efficiency.
[0135] For example, in combination Figure 7-9 It can be seen that the exhaust system 2 and the engine 1 are located between the front bulkhead 9 and the radiator 4, and the exhaust port 23 is located in front of the battery 5;
[0136] The exhaust system 2 is located at least one of the first region 6 (left or right or both sides along the lateral direction of the vehicle) and the second region 7 (along the height direction of the vehicle) of the engine 1; or, the exhaust system 2 is located at at least one of the first region 6 (left or right or both sides along the lateral direction of the vehicle), the second region 7 (lower side along the height direction of the vehicle), and the third region 8 (front side along the longitudinal direction of the vehicle).
