Zusammenfassung:To provide a longitudinally-scavenged large engine capable of more reliable scavenging.SOLUTION: There is proposed a longitudinally-scavenged large engine having at least one cylinder 10 in which a piston 60 is disposed to be movable back and forth along a cylinder shaft X, and having a cylinder cover 20 which together with the piston 60, defines a combustion chamber 120 for fuel. The large engine is designed for operation in a gas mode in which a premixed air-fuel mixture is burned in the combustion chamber 120, and a plurality of outlet valves 40 are provided inside the cylinder cover 20 to discharge exhaust gas from the combustion chamber 120. In each case, a ridge is provided between two adjacent outlet valves 40 on the cylinder cover 20, and the ridge extends into the combustion chamber 120.SELECTED DRAWING: Figure 1 【課題】より確実な掃気を可能にする長手方向掃気式大型エンジンを提供すること。【解決手段】ピストン60がシリンダ軸Xに沿って前後に移動可能であるように配置された少なくとも1つのシリンダ10を有し、ピストン60とともに、燃料のための燃焼室120の境界を定めるシリンダ・カバー20を有する、長手方向掃気式大型エンジンが提案される。大型エンジンは、予混合空気燃料混合気が燃焼室120で燃焼されるガス・モードでの運転のために設計され、複数の出口弁40が、燃焼室120から排気ガスを排出するために、シリンダ・カバー20内に設けられ、いずれの場合にもシリンダ・カバー20上の2つの隣接する出口弁40の間に隆起が設けられ、その隆起は、燃焼室120内に延在している。【選択図】図1
