The right cylinder block 200 is provided with two right piston cylinders. The two right piston cylinders are respectively a first right piston cylinder and a second right piston cylinder. The first right piston cylinder is symmetrically disposed with the first left piston cylinder and the axes of the two are coincident. The second right piston cylinder is symmetrically disposed with the second left piston cylinder and the axes thereof are coincident. The plurality of left piston cylinders 105 and the plurality of right piston cylinders are symmetrically disposed.
左缸体100和右缸体200通过螺栓可拆卸连接从而共同构成曲轴300箱，曲轴300箱内设置有可转动的曲轴300，曲轴300上设置有两个曲拐310，两个曲拐310分别为第一曲拐310和第二曲拐310。第一曲拐310和第二曲拐310上均连接有两个连杆400，每个连杆400远离曲轴300的一端均连接有活塞，第一曲拐310上的两个活塞分别滑动连接于第一左活塞缸和第一右活塞缸内，第二曲拐310上的两个活塞分别滑动连接于第二左活塞缸和第二有活塞缸内。The left cylinder block 100 and the right cylinder block 200 are detachably connected by bolts to jointly form a crankcase 300. The crankshaft 300 is provided with a rotatable crankshaft 300. The crankshaft 300 is provided with two cranks 310, and the two cranks 310 respectively It is a first crank 310 and a second crank 310. Two links 400 are connected to each of the first crank 310 and the second crank 310. Each of the links 400 is connected to a piston at one end of the crankshaft 300, and the two pistons on the first crank 310 are respectively slidably connected to In the first left piston cylinder and the first right piston cylinder, the two pistons on the second crank 310 are slidably coupled to the second left piston cylinder and the second piston cylinder, respectively.
其中，左缸体100和右缸体200结构类似且整体均呈长方体形，相应地，曲轴300箱整体也呈长方体形；左缸体100和右缸体200相互连接的部位分别设置有多个半圆柱形的支撑孔，左缸体100和右缸体200连接后，两者的半圆柱形的支撑孔一一对应从而形成多个圆柱形的支撑孔，上述多个圆柱形的支撑孔与曲轴300上的多个圆柱形的支撑部一一匹配；曲轴300的曲拐310和支撑部之间设置有平衡块，以降低曲轴300高速旋转后的振动幅度和频 率；曲拐310和连杆400之间设置有滑动轴承，以保证两者相对转动的流畅性。The left cylinder 100 and the right cylinder 200 are similar in structure and have a rectangular parallelepiped shape as a whole. Accordingly, the crankcase 300 is also in the shape of a rectangular parallelepiped; the left cylinder 100 and the right cylinder 200 are respectively connected to each other. a semi-cylindrical support hole, after the left cylinder 100 and the right cylinder 200 are connected, the semi-cylindrical support holes of the two are in one-to-one correspondence to form a plurality of cylindrical support holes, and the plurality of cylindrical support holes and A plurality of cylindrical support portions on the crankshaft 300 are matched one by one; a balance block is disposed between the cranks 310 of the crankshaft 300 and the support portion to reduce the amplitude and frequency of vibration of the crankshaft 300 after high-speed rotation Rate; a sliding bearing is disposed between the crank 310 and the connecting rod 400 to ensure the smoothness of the relative rotation of the two.
本水平全对置内燃机的工作原理和过程是这样的：首先活塞在燃烧产生的能量的推动下在活塞缸内做直线往复运动；然后连杆400在活塞的推动下在曲轴300箱内运转；之后曲轴300在连杆400的推动下在曲轴300箱内高速转动，最后高速转动的曲轴300的动力从输出端输出，以便为配套设备(比如发电机等)提供动力。这样，燃料燃烧产生的热能就被转化为机械能了。The working principle and process of the horizontally opposed internal combustion engine are as follows: firstly, the piston makes a linear reciprocating motion in the piston cylinder under the driving of the energy generated by the combustion; then the connecting rod 400 is driven by the piston in the crankcase 300; Thereafter, the crankshaft 300 is rotated at a high speed in the crankcase 300 under the pushing of the connecting rod 400, and finally the power of the high-speed rotating crankshaft 300 is output from the output end to power the supporting equipment (such as a generator, etc.). In this way, the heat generated by the combustion of the fuel is converted into mechanical energy.
现有的内燃机的活塞缸大多都是沿一条直线间隔排列于曲轴300的一侧的，导致整个缸体体积较大，尤其是长度方向的跨度较大，相应地，曲轴300也较长，从而大大提高了加工的难度和成本，同时，由于轴承只是单侧受到活塞和连杆400的冲击，因此曲轴300的平衡性也不好，运转时噪声和振动剧烈。The piston cylinders of the existing internal combustion engines are mostly arranged on one side of the crankshaft 300 along a straight line, resulting in a larger volume of the entire cylinder, especially a longer span in the longitudinal direction, and accordingly, the crankshaft 300 is also longer. The difficulty and cost of the machining are greatly improved. At the same time, since the bearing is only impacted by the piston and the connecting rod 400 on one side, the balance of the crankshaft 300 is also not good, and noise and vibration are severe during operation.
针对上述问题，本技术方案提供的水平全对置内燃机采用双缸体结构，且活塞缸两两一组对称设置于两个缸体上且两个对称的活塞缸的轴线重合，相应地，连杆400和活塞也两两一组分别位于曲轴300的两侧且分别对应曲轴300两侧的缸体和活塞缸，这就可以从很大程度上减小缸体长度方向的跨度，缩短曲轴300的长度，降低曲轴300加工的难度和成本，同时由于曲轴300的两侧均会受到活塞和连杆400的冲击，使得两侧受到的冲击力可以相互抵消，从而提高曲轴300的平衡性，降低整个水平全对置内燃机运转时的噪声和振动，即有效改善本增程器的NVH(噪声、振动与声振粗糙度)问题。In view of the above problems, the horizontal full-opposed internal combustion engine provided by the technical solution adopts a double-cylinder structure, and two sets of piston cylinders are symmetrically disposed on two cylinders and the axes of two symmetric piston cylinders coincide, correspondingly, The rod 400 and the piston are also respectively disposed on both sides of the crankshaft 300 and respectively correspond to the cylinder block and the piston cylinder on both sides of the crankshaft 300, which can greatly reduce the span of the cylinder length direction and shorten the crankshaft 300. The length reduces the difficulty and cost of machining the crankshaft 300. At the same time, since both sides of the crankshaft 300 are subjected to the impact of the piston and the connecting rod 400, the impact forces received on both sides can cancel each other, thereby improving the balance of the crankshaft 300 and reducing the balance. The noise and vibration during the operation of the entire horizontally opposed internal combustion engine effectively improve the NVH (noise, vibration and harshness) of the present extender.
