[0023] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0024] It should be noted that like numbers and letters refer to like items throughout the drawings, and that, once an item is defined in one drawing, it need not be discussed further in subsequent drawings.

[0025] As shown in FIG. 1 to FIG. 6, according to the first aspect of the present application, a power system applied to a vehicle is provided, comprising: an engine body 2 comprising a cylinder and a crankshaft 208; the engine body 2 is inclined to one side along the rotation center of the crankshaft 208, so that the center line of the cylinder has a set angle a with the vertical direction.

[0026] Specifically, the power system can be arranged in the engine compartment of the vehicle as the power source of the vehicle. In the embodiment, by arranging the engine body 2 to be inclined to one side along the rotation center of the crankshaft 208, the arrangement space available on the side away from the inclined side of the engine body 2 can be increased, which can be inclined to the front side or the rear side. As shown in FIG. 1, when the engine body 2 is inclined to the rear side, the upper and lower parts of the front side of the engine body 2 are increased by a part of the arrangement space. In actual application, other related parts of the power system can be arranged here to improve the integration of the entire power system, and when the power system is assembled in the engine compartment, the integration of the entire engine compartment of the vehicle can be improved. Wherein, the front side and the rear side of the engine are consistent with the front and the rear of the vehicle.

[0027] In addition, after the engine body 2 is inclined, the center line of the cylinder and the vertical direction can form a certain angle a, as shown in FIG. 2, B is a schematic view of the engine body 2 before being inclined, and A is a schematic view of the engine body 2 after being inclined. In actual application, since the arrangement of each engine body 2 and the parts of the power system is not the same, the set angle a can be designed according to the actual space size and the performance requirements of the engine body 2 to form a suitable size of arrangement space, so as to improve the integration of the power system while considering practicability.

[0028] Optionally, as shown in FIG. 1 to FIG. 2, the angle range of the set angle is 15°-40°.

[0029] Specifically, in actual application, if the angle of the set angle is too large, the intake manifold of the engine body 2 arranged in the engine compartment will exceed the boundary of the engine compartment due to the too high height, which is not conducive to the assembly of the entire vehicle, and if the angle of the set angle is too small, the space left by the inclined engine body 2 will be too small to arrange other parts. In the embodiment, the range of the set angle is limited to 15°-40°, so that the inclination of the engine body 2 can take into account the integration and assembly difficulty of the power system. Further, the set angle can be selected to be about 20°-30°.

[0030] Optionally, referring to FIG. 1, the power system further comprises an exhaust system 3, the engine body 2 is inclined to the rear side, leaving an open space below the front side of the engine body 2; the front-rear direction of the engine body 2 is consistent with the forward direction of the vehicle, and the exhaust system 3 is located on the front side of the engine body 2 and at least part of the exhaust system 3 is located in the open space.

[0031] Specifically, in actual application, the engine body 2 is inclined to the rear side, so that the open space left can be below the front side of the engine body 2. When the exhaust system 3 is arranged here, on the one hand, the front side is usually provided with heat dissipation equipment such as a cooling fan, which can cool the exhaust system 3, and on the other hand, the heat of various connecting wire harnesses and other heat-generating devices arranged on the rear side of the engine body 2 can also be prevented from affecting the exhaust system 3.

[0032] As can be seen from the above embodiment, by inclining the engine body 2 to the rear side, the exhaust system 3 originally arranged at the tail of the vehicle can be integrated into the open space left on the front side of the engine body 2, thereby improving the integration of the power system, and the heat damage of the exhaust system 3 can also be prevented from affecting other components of the power system. In addition, in a hybrid vehicle, by arranging the exhaust system 3 in the open space, the exhaust system 3 can also pass through the battery pack of the vehicle, thereby improving the safety of the vehicle.

[0033] In an embodiment, referring to FIG. 6, the exhaust system 3 comprises an exhaust inlet 301, a muffler 302 and an exhaust outlet 303, the exhaust in the engine body 2 enters the muffler 302 through the exhaust inlet 301, and after noise reduction treatment by the muffler 302, the exhaust is discharged into the atmosphere through the exhaust outlet 303. The volume of the muffler 302 usually affects the noise reduction effect, so arranging at least part of the muffler 302 in the open space can expand the volume of the muffler 302 and ensure the noise reduction effect.

[0034] Optionally, as shown in FIGS. 3-5, the engine body 2 further comprises a cylinder head 206, a cylinder block 207 and an oil pan 209, the cylinder and the crankshaft 208 are arranged inside the cylinder block 207 from top to bottom, the cylinder head 206 is arranged above the cylinder block 207, and the oil pan 209 is arranged below the cylinder block 207 and avoids the open space. In addition, the engine body 2 further comprises an oil filter 210, and the oil filter 210 is arranged side by side at one side of the oil pan 209.

[0035] Specifically, the crankshaft 208 is usually arranged at the bottom of the cylinder block 207, and the cylinder is arranged above the crankshaft 208 to realize the basic function of the engine. In the embodiment, some components originally arranged at the rear side of the engine body 2 can be arranged above the cylinder head 206 to balance the positions of the components. However, the arrangement also causes the overall height of the engine body 2 to be relatively high. Therefore, the oil pan 209 is arranged offset from the original position directly below the engine body 2, that is, the oil pan is arranged below the cylinder block 207 and avoids the open space. In addition, the oil filter 210 is arranged at the right side of the oil pan 209 instead of the front side of the oil pan 209, so that the open space below the front side of the engine body 2 can be used to arrange other components, and the overall height of the engine body 2 is reduced.

[0036] Optionally, referring to FIG. 3, the power system further comprises a turbocharging assembly arranged at the front side of the engine body 2 and above the cylinder head 206.

[0037] Specifically, in the prior art, the turbocharging assembly is usually arranged at the rear side of the engine body 2. In the embodiment, after the engine body 2 is tilted, the space above the front side of the cylinder head 206 is also increased. Therefore, the turbocharging assembly is arranged above the front side of the cylinder head 206, which realizes flexible arrangement of the components at the rear side of the engine body 2 and efficient use of space.

[0038] Optionally, referring to FIG. 3, the turbocharging assembly comprises an intake pipe 201, a compressor 202, and an exhaust turbine, which are arranged in sequence along the left-right direction of the cylinder head 206. The left-right direction of the cylinder head 206 is consistent with the left-right direction of the vehicle. In addition, the power system further comprises a catalyst 205 arranged at the front side of the engine body 2, one end of which is arranged at the right side of the exhaust turbine, and the other end extends downward along the cylinder head 206 to the position of the cylinder block 207.

[0039] Specifically, in actual application, the turbocharger assembly is arranged at the upper side of the cylinder head 206, and the turbocharger assembly generally comprises an intake pipe 201, a compressor 202 and an exhaust turbine. Referring to FIG. 3, the intake pipe 201 can be arranged at the leftmost side of the cylinder head 206, the right side is connected with the compressor 202, the exhaust turbine is arranged at the right side of the compressor 202, the inlet part of the catalytic converter 205 is at the right side of the exhaust turbine, the remaining part is at the front right side of the cylinder head 206 and the cylinder block 207, and the catalytic converter 205 is partially overlapped with the engine from top to bottom, and is not completely arranged outside the engine. In this way, the turbocharger assembly can be arranged at the front side of the engine body 2 instead of the rear side of the engine body 2, and the arrangement space at the front side can be effectively utilized, and the turbocharger assembly is also convenient to connect with related parts, and the integration of the power system is further improved.

[0040] In another embodiment, referring to FIG. 3, the power system further comprises an EGR (Exhaust Gas Recirculation) cooler 204, which is arranged above the cylinder head 206 and at the right side of the catalytic converter 205, so as to effectively utilize the space above the cylinder head 206.

[0041] Optionally, as shown in FIG. 4, the power system further comprises an oil cooler 211, a high-pressure oil pump 212 and an intake intercooler 213, the high-pressure oil pump 212 and the intake intercooler 213 are arranged at the rear side of the cylinder head 206, and the oil cooler 211 is arranged at the rear side of the cylinder block 207. In addition, a thermostat 214 is arranged at the left side of the cylinder block 207.

[0042] Specifically, in this embodiment, each part originally arranged at the front side of the engine body 2 can be flexibly adjusted, so as to further improve the rationality of the arrangement of each part and the integration of the entire power system. That is, the oil cooler 211 is arranged at the right side of the middle part of the rear side of the cylinder block 207 instead of the middle part of the front side of the cylinder block 207, the high-pressure oil pump 212 is arranged at the left side of the rear side of the cylinder head 206 instead of the left side of the upper side of the cylinder head 206. The intake intercooler 213 is arranged at the middle part of the rear side of the cylinder head 206 instead of the middle part of the upper side of the cylinder head 206, and the thermostat 214 is arranged at the left side of the outside of the cylinder block 207 instead of the front side of the cylinder block 207.

[0043] Optionally, as shown in FIG. 1, an intake system 1 is further arranged above the engine body 2 and the exhaust system 3.

[0044] Specifically, the air intake system 1 mainly consists of an air cleaner, an air cleaner inlet pipeline and an air cleaner outlet pipeline. The air cleaner inlet pipeline introduces external air through a flow guide structure, the air cleaner filters dust and impurities in the air, and then the air flows to the engine body 2 through the air cleaner outlet pipeline. In this embodiment, the air intake system 1 is arranged above the engine body 2 and the exhaust system 3, which is beneficial to the arrangement of each part of the entire power system.

[0045] According to a second aspect of the present application, with reference to FIGS. 1-6, a vehicle is provided, comprising the power system of the first aspect.

[0046] Specifically, in this embodiment, the vehicle uses the power system provided by the first aspect of the present application as a power source. Since the engine body 2 is arranged obliquely, the upper and lower parts of the front side can increase a part of the position space, so that by adjusting the arrangement position of each part of the entire power system, the integration of the power system can be improved. The power system is usually arranged in the engine compartment in the vehicle body structure, and thus the integration of the engine compartment of the entire vehicle is high.

[0047] In the above embodiments, the differences between the embodiments are mainly described. The different optimization features of the embodiments can be combined to form a better embodiment as long as they are not contradictory. Considering the brevity of the writing, it will not be repeated here.
