Embodiment approach

[0034] The upper body 1 of the oil pan is a long plate-like structure, and the two ends of the upper body 1 of the oil pan are even, and the middle part is sunken.

[0035] The oil return ports include: an oil return port 11 for outer piston cooling machine oil, an oil return port 12 for inner piston cooling machine oil and an oil return port 13 for gear chamber machine oil. The outer piston cooling oil return ports 11 are arranged at both ends of the upper body 1 of the oil pan, and are used for the oil return of the outer piston cooling oil. The inner piston cooling machine oil return port 12 is arranged in the middle part of the upper body 1 of the oil pan, and is used for oil return of the inner piston cooling machine. The oil return port 13 of the gear chamber is arranged in the middle of the upper body 1 of the oil pan, on the side of the inner piston cooling oil return port 12. There are several oil return ports 13 in the gear chamber for gear Oil return of indoor mach...

Abstract

The invention discloses an oil pan assembly for a two-stroke horizontally-opposed-piston and opposed-cylinder engine. The oil pan assembly comprises an upper oil pan body, a middle oil pan body and a lower oil pan body. The upper oil pan body is of a strip-shaped platelike structure. The two ends of the upper oil pan body are flush with each other, and the middle of the upper oil pan body is sunk. The upper oil pan body is provided with an oil return opening set and an oil pump oil inlet. The middle oil pan body is arranged below the upper oil pan body and matched with the upper oil pan body in structure. The middle portion of the middle oil pan body is hollowed out. Oil ways are arranged in the middle oil pan body. The lower oil pan body is arranged on the lower portion of the middle oil pan body. An oil discharging opening is formed in the lower oil pan body. According to the oil pan assembly, a cavity structure is formed jointly through the upper oil pan body, the middle oil pan body and the lower oil pan body, the waste gas sucking and exhausting working pressure of engine pistons on the two sides can be balanced effectively, and meanwhile the requirement for batch production is met.

Description

technical field [0001] The invention relates to the technical field of two-stroke engines, in particular to an oil pan assembly of a two-stroke engine with horizontally opposed pistons and opposed cylinders. Background technique [0002] The horizontally opposed engine, with its unique engine structure and working principle, can obtain higher mechanical efficiency and combustion efficiency than traditional engines. Especially the two-stroke OPOC engine (opposed-piston, opposed-cylinder, horizontally opposed piston, opposed cylinder engine), because of its compact structure, its energy density can reach the high-tech level of the same industry (≥90kW / L,≥ 1.9kW / kg), which has attracted the attention of the industry because of these two advantages. [0003] The OPOC engine oil pan assembly needs to realize all the functions of the oil pan of the traditional internal combustion engine. According to the structural characteristics of the OPOC engine, the oil pan assembly must als...
