Abstract

The invention discloses an engine and an all-terrain vehicle. The engine comprises a crankcase and a rotating shaft; the crankcase is internally provided with a main cavity, a communication cavity anda separation cavity; the communication cavity is formed in one side of the main cavity; the separation cavity communicates with the communicating cavity and is internally provided with a separation structure; the rotating shaft is rotatably arranged in the main cavity and an axial end of the rotating shaft extends into the communicating cavity; and the rotating shaft is provided with a first communication hole communicating with the main cavity and the communication cavity. Therefore, on the basis of the rotating shaft, by providing the separation chamber, oil and gas separation can be further performed, and the oil and gas separation effect of the engine can be improved; and an oil and gas separation device does not need to be independently arranged, and therefore, the cost of the enginecan be reduced, the layout of the engine is simplified, and the structure is more reliable.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an engine and an all-terrain vehicle. Background technique [0002] In the related art, when the engine is working, part of the unburned mixed gas and burned exhaust gas in the cylinder will escape into the crankcase along the gap between the piston assembly and the cylinder wall. In the exhaust gas that escapes into the crankcase of the engine, its components are mainly HC and a small part of CO and NOx. These exhaust gases will have the following hazards: 1. HC and engine oil will interact with the oil to deteriorate the engine oil and form deposits, causing the formation of piston rings, etc. Carbon deposits and deposits; 2. Cause the engine oil working surface to rust; 3. It will increase the pressure of the crankcase and make the lubricating oil seep from the oil seal, gasket and filler port. [0003] For this reason, these exhaust gases in the crankcase are usually introd...
