Problems solved by technology

In addition, horizontal opposition can offset the lateral vibration, which is only an ideal situation. If the valve cannot be completely closed due to carbon deposits and other reasons, it will also cause unequal cylinder pressure, which will cause unequal lateral force. In this case It will also cause left and right jitter

Embodiment

[0022] A horizontally opposed engine, including cylinder heads, intake ducts, exhaust ducts, fuel injectors, cylinder blocks, cylinder liners and pistons. Such as figure 1 with figure 2 As shown, for the sake of simplicity, only the cylinder, piston, transmission and power output are shown in the figure, and the rest are omitted.

[0023] As shown in the figure, a horizontally opposed engine has a cylinder block 10 with four horizontally opposed cylinders, and the four cylinders are respectively provided with a piston 11, a piston 2 12, a piston 3 13 and a piston 4 14 therein. It also includes a connecting rod assembly and a gear transmission mechanism, wherein the connecting rod assembly includes a connecting rod 21 and a connecting rod 22. The two ends of the connecting rod 21 are connected to the piston 11 and the piston 12 through a piston pin. The two ends of 22 are respectively connected with piston three 13 and piston four 14 through piston pins. In order to further imp...

Abstract

The invention discloses a horizontal opposed engine. The horizontal opposed engine comprises four air cylinders arranged horizontally and oppositely, pistons arranged in the air cylinders, a connecting rod assembly and a gear transmission mechanism. The connecting rod assembly comprises a first connecting rod and a second connecting rod. The two ends of the first connecting rod are connected with the first piston and the second piston correspondingly, and the two ends of the second connecting rod are connected with the third piston and the fourth piston correspondingly. The gear transmission mechanism comprises a first ratchet wheel, a second ratchet wheel, a first gear, a second gear and a transmission gear. The first ratchet wheel and the first gear are arranged coaxially. The second ratchet wheel and the second gear are arranged coaxially, and the first ratchet wheel and the second ratchet wheel are same in direction. The transmission gear is arranged between the first gear and the second gear and engaged with the first gear and the second gear. The first connecting rod and the second connecting rod are provided with racks correspondingly. The racks on the connecting rods are engaged with the ratchet wheels. The transmission gear is connected with a power output shaft. Compared with traditional crank-connecting-rod structures, through the adopted connecting rod mechanism, the design requirements of the air cylinders is simplified, and the impact force of high-pressure gas on the pistons is offset to a certain degree.

Description

Technical field [0001] The invention belongs to the technical field of engines, and specifically relates to a novel horizontally opposed engine. Background technique [0002] The horizontally opposed engine was first developed by the well-known car company Subaru Group. At present, the horizontally opposed engine is mainly used in some models of the Subaru and Porsche groups. Since its introduction in 1966, the horizontally opposed engine (SUBARU BOXER) has integrated a low center of gravity, smooth linear acceleration, precise engine response, and ample torque output in the low-speed range. Through continuous improvement and enhancement, Subaru has achieved outstanding performance. Control performance and deliver a unique sports experience. [0003] For horizontally opposed engines, the engine pistons are evenly distributed on both sides of the crankshaft and move left and right in the horizontal direction, which can reduce the overall height and length of the engine, lower the c...
