Longitudinal scavenging large engine

The invention relates to a longitudinal scavenging large engine having at least one cylinder (10) in which a piston (60) is arranged so as to be movable back and forth along a cylinder axis (X), said cylinder having a cylinder head (20), which together with the piston (60) delimits a combustion chamber (120) for fuel. The large engine is designed to operate in a gaseous mode in which a premixed air-fuel mixture is combusted in the combustion chamber (120), in which a plurality of outlet valves (40) are provided in the cylinder head (20) for discharging exhaust gas from the combustion chamber (120), and in each case, a projection is provided on the cylinder head (20) between every two adjacent outlet valves (40), said projection extending into the combustion chamber (120). 本发明涉及一种纵向扫气的大型发动机，所述纵向扫气的大型发动机具有至少一个气缸(10)，在所述气缸中活塞(60)被布置成可沿着气缸轴线(X)来回移动，所述气缸具有气缸盖(20)，所述气缸盖与所述活塞(60)一起界定用于燃料的燃烧室(120)，所述大型发动机被设计成在气体模式下工作，在所述气体模式下预混合的空气燃料混合物在所述燃烧室(120)中燃烧，其中，所述气缸盖(20)中设置有多个出口阀(40)，用于从所述燃烧室(120)排出废气，并且其中，在每种情况下，在所述气缸盖(20)上
