Multi-cylinder engine

An internal combustion engine may include: a first piston reciprocatingly disposed in a first cylinder; a combustion chamber fluidly coupled with the first cylinder; and an ignition source 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. A second piston may be reciprocatingly disposed within the second cylinder. An inlet associated with the second cylinder may be fluidly coupled with the intake system and an outlet may be fluidly coupled with one or more of the first cylinder and the combustion chamber. A crankshaft may be coupled with the first piston and the second piston for rotational motion associated with reciprocating motion of the first piston and the second piston. 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；燃烧室，该燃烧室与第一汽缸流体地联接；以及点火源，该点火源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，
