Problems solved by technology

[0002] The engine crankcase is the part used to install the crankshaft, and lubricating oil is stored in the crankcase. The bottom of the existing engine crankcase is generally a flat structure. This structure has many disadvantages. First, this structure causes the crankshaft to The liquid level of the lubricating oil in the tank is low, and the lubricating oil in the tank cannot be fully circulated. Secondly, the impurities generated during the use of the lubricating oil are scattered and deposited on the bottom of the crankcase, making it difficult to remove the impurities and increase the engine capacity. wear and tear, affecting the service life of the engine; again, the bottom of the engine crankcase is provided with a bottom plate, which makes the structure complex and difficult to install; in addition, when the lubricating oil needs to be replaced, it is difficult to remove the used lubricating oil from the crankcase, thereby Affects the quality of new lubricating oil injected

Embodiment Construction

[0016] figure 1 It is a structural schematic diagram of the present invention, as shown in the figure, the engine crankcase provided by the present invention includes a crankcase body 1, and the bottom of the crankcase body 1 sinks to form a sinker 2 for collecting oil, and the setting of the sinker 2 , the capacity of the box is increased, and the lubricating oil can be concentrated, which is beneficial to the recycling of all lubricating oil and optimizes oil absorption; it can effectively gather and completely remove impurities, reduce engine wear and prolong the service life of the engine; replace new lubricating oil When it is used, the used lubricating oil can be completely removed to ensure the quality of the newly injected lubricating oil; there is no need to install the bottom plate, the structure is simplified, and the material and cost are saved.

[0017] In this embodiment, the oil inlet 5 of the lubricating oil circulation system is located in the sinker 2 and clo...

Abstract

The invention provides an engine crankcase, which comprises a crankcase body, wherein the bottom of the crankcase body sinks to form a sunken tank for collecting lubricating oil. The capacity of the case body is enlarged enough to centralize the lubricating oil, recycling of the total lubricating oil is facilitated, and oil absorption is optimized; impurities can be aggregated effectively and removed completely, the engine abrasion can be reduced, and the service life of the engine can be prolonged; when the lubricating oil is renewed, the used lubricating oil can be removed completely, and the quality of newly filled lubricating oil is guaranteed; and a baseplate is not needed to mount, so that the structure is simplified, and materials and costs are saved.
