COMBUSTION ENGINE AND OPERATING METHOD THEREOF

A combustion motor (1) has a cylinder (2) and a piston (5), wherein a combustion chamber (3) is formed in the cylinder (2) and the piston (5) delimits the combustion chamber (3). The combustion motor(1) has at least one overflow channel (14) which establishes a fluid connection between a crankcase interior (24) of a crankcase (4) and the combustion chamber (3) in the region of a bottom dead center of the piston (5). The combustion motor (1) has a fuel supply device which supplies fuel into the first overflow channel (14) between a first overflow window (15) of the first overflow channel (14)and a first inlet opening (25) of the first overflow channel (14). 燃烧马达（1）拥有气缸（2）和活塞（5），其中在所述气缸（2）构造有燃烧室（3）并且所述活塞（5）限定所述燃烧室（3）。所述燃烧马达（1）拥有至少一个溢流通道（14），所述溢流通道在所述活塞（5）的下死点的区域中建立曲轴箱（4）的曲轴箱内部空间（24）与所述燃烧室（3）之间的流体的连接。所述燃烧马达（1）拥有燃料输送机构，所述燃料输送机构将燃料在所述第一溢流通道（14）的第一溢流窗口（15）与所述第一溢流通道（14）的第一汇入口（25）之间输送到所述第一溢流通道（14）中。
