Problems solved by technology
Therefore, this kind of oil cooler cannot make the engine run at the optimum lubricating effect under all working conditions
As a result, the mechanical loss and mechanical wear of the engine increase, which is not conducive to reducing fuel consumption
In addition, the use of an external oil cooler increases the number of engine parts and engine mass, which in turn increases the processing and installation procedures of the engine, which is not conducive to engine integration and light weight

Embodiment Construction
[0027] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0028] The oil return channel on the cylinder block of the existing engine is a through-hole structure, which directly connects the cylinder head and the oil pan, and the returned oil directly flows back to the oil pan from the cylinder head and the cylinder block, and the space utilization effect of the oil return channel of the cylinder block is improved. Difference.
[0029] Moreover, the external engine oil cooler added in the prior art needs to increase the corresponding oil passages and water passages, thereby increasing the quality of the engine, the processing procedures, and the installation procedures, which is not conducive to the reduction of production costs, and is also not conducive to the light weight and integration of the engine. .
[0030] The most important thing is that the engine oil i...

The invention provides an engine and a vehicle provided with the same. The engine comprises a cylinder cover, a cylinder body and an oil returning passage, wherein a cylinder cover water jacket is arranged inside the cylinder cover; a cylinder body water jacket and a cylinder body water distribution channel are arranged inside the cylinder body; cooling liquid of the engine sequentially flows through the cylinder body water jacket, the cylinder cover water jacket and the cylinder body water distribution channel; the oil returning passage is at least partially formed inside the cylinder body; the oil returning passage comprises a first oil returning passage and a second oil returning passage which are separated from each other; the first oil returning passage is adjacent to the cylinder body water jacket to realize indirect heat exchange between the cooling liquid flowing in the first oil returning passage and the cooling liquid flowing in the cylinder body water jacket; the second oil returning passage is adjacent to the cylinder body water distribution channel to realize indirect heat exchange between the cooling liquid flowing in the second oil returning passage and the cooling liquid flowing in the cylinder body water distribution channel, wherein the engine oil of the engine can selectively flow back to an oil pan through the first oil returning passage and / or the second oil returning passage. The engine provided by the invention can make the engine oil be within a suitable temperature range all the time so as to guarantee that the engine is always in an optimal lubrication effect.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to an engine and a vehicle with the same. Background technique [0002] Existing engines generally have an external oil cooler that is heated or cooled by the engine coolant. However, this type of oil cooler can only keep the temperature of the engine oil at the optimum temperature under a certain working condition, and only keep the temperature of the engine oil within a reasonable range under other working conditions. Therefore, this kind of engine oil cooler cannot make the engine run at optimal lubricating effect in all working conditions. As a result, the mechanical loss and mechanical wear of the engine increase, which is not conducive to reducing fuel consumption. In addition, the use of an external oil cooler increases the number of engine components, increases the quality of the engine, and further increases the processing and installation procedures of the engine, which...
