Multi-cylinder engine

An internal combustion engine may include: a first piston reciprocatingly disposed in a first cylinder; and a second piston reciprocatingly disposed in the second cylinder. A crankshaft may be coupled with the first piston and the second piston for rotational motion associated with reciprocating motion of at least one of the first piston and the second piston. A combustion chamber may be fluidly coupled with the first cylinder and the second cylinder. The ignition source may be at least partially disposed within the combustion chamber. An intake valve may provide selective fluid communication between the intake system and the combustion chamber, and an exhaust valve may provide selective fluid communication between the exhaust system and the combustion chamber. 内燃发动机可以包括：第一活塞，该第一活塞往复地设置在第一汽缸中；以及第二活塞，该第二活塞往复地设置在第二汽缸中。曲轴可以与第一活塞和第二活塞联接，以用于与第一活塞和第二活塞中的至少一者的往复运动相关联的旋转运动。燃烧室可以与第一汽缸和第二汽缸流体地联接。点火源可以至少部分地设置在燃烧室内。进气门可以在进气系统与燃烧室之间提供选择性的流体连通，并且排气门可以在排气系统与燃烧室之间提供选择性的流体连通。
