Adjustable single cylinder engine body structure

Abstract

The invention relates to an adjustable single cylinder engine body structure. A cylinder hole (6) is arranged in a cylinder body (1), a cylinder sleeve support (7) is arranged inside the cylinder hole (6), the left side of the cylinder body (1) is provided with an air distribution tappet hole (8), a cam shaft supporting hole (9) and an air distribution oil return hole (10). A crankcase (3) is arranged at the lower portion of the cylinder body (1), an adjusting plate (2) is arranged between the cylinder body (1) and the crankcase (3), a positioning mouth opening (18) is positioned on the adjusting plate (2, the lower portion of the crankcase (3) is provided with a connecting rod dismounting hole (11), and the left wall of the crankcase (3) is provided with a longitudinal main oil way (14). A first arched partition plate (12), a second arched partition plate (12) and a third arched partition plate (12) are longitudinally arranged on the crankcase (3), correspond to a top-arranged bearing cover (4) and are connected with the top-arranged bearing cover (4) through an engine oil transition device (5), an installing hole of the engine oil transition device (5) is arranged at the upper portion of the top-arranged bearing cover (4), and a main bearing hole (13) is arranged at the lower portion of the top-arranged bearing cover (4). By means of the adjustable single cylinder engine body structure, the economic investment for engine study is reduced, and the utilization ratio is improved.

Description

[0001] technical field [0002] The invention belongs to a part of a single-cylinder engine, and in particular relates to an adjustable single-cylinder engine body structure. Background technique [0003] The single-cylinder engine is the basic platform for the performance research of the whole engine. Through this platform, it can provide the experimental basis for the power performance, economic performance and parameter matching of the future multi-cylinder research, and it is the test guarantee for the early performance research of the engine. Functionally, the single-cylinder machine body has the ability to support the crank-connecting rod mechanism, gas distribution mechanism, external accessories and cylinder liners and other mechanisms and parts, and to ensure that the working environment of each mechanism is good, the movement of the mechanism is coordinated and stable, the system performance is reliable, and the rigidity, The role of reducing vibration and suppress...

Problems solved by technology

However, the extensive structural design will inevitably bring many shortcomings, such as the large body structure, small volume power, and low compactness; the mass of the body makes it difficult to process and disassemble; the oil passage layout of the body is messy, and the test environment is seriously polluted; The combination of the body is poor in deformation ability, the degree of specialization is not high, the scope of application of the body is narrow, the reuse rate is low, and the application cost is high.
