Description

Technical Field

[0001] The utility model relates to the technical field of internal combustion engines, in particular to an opposed engine frame structure. Background Art

[0002] The opposed cylinder engine is an efficient and balanced engine design, and its unique advantages make it very valuable in specific application areas. With the advancement of technology, the design and manufacture of opposed cylinder engines may become more economical and efficient in the future. However, in addition to the complex structure of the horizontally opposed engine, the horizontally placed cylinder will cause the oil to flow to the bottom due to gravity, so that one side of the cylinder cannot be fully lubricated. Therefore, there are problems such as manufacturing difficulties and uneven lubrication of the upper and lower cylinder holes, which makes it unfavorable for large-scale application. In addition, the opposed engines on the market are generally gasoline engines with low explosion pressure. The main bearing bolts are set in the engine cavity. The bolts are fastened from the top surface of the cylinder block to the cylinder block on the opposite side. Due to the limitation of the position of the cylinder hole and the cylinder head bolts, the bolt tightening position is far away from the main bearing hole. For working conditions with excessive explosion pressure, the risk of cylinder hole deformation is high. For opposed engines used in diesel engines, it is particularly important to design the bolts close to the main bearing hole.

[0003] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.
