Abstract | The invention discloses an engine cylinder block oil return pipeline structure, and relates to the field of an internal combustion engine. The engine cylinder block oil return pipeline structure comprises an oil return pipeline arranged in an engine cylinder block, the oil return pipeline is used for communicating a cylinder cover and an oil pan, the return oil pipeline is provided with at least one speed reduction slope section, and the speed reduction slope section is used for reducing flow velocity of engine oil flowing from the cylinder cover to the oil pan. The engine cylinder block oil return pipeline structure provided by the invention can reduce the flow velocity of the engine oil flowing from the cylinder cover to the oil pan in the oil return pipeline, can prevent the engine oilfrom sputtering caused by high-speed flowing and impact in a process from a high position to a low position, consequently reduces gas content of the engine oil, and avoids generation of a respiratorymode like beating a drum, |
