Abstract: A supercharging engine supplying compressed air to a combustion chamber as intake air may include at least two cylinders, a deactivation cylinder being at least one of the cylinders, and selectively deactivated, a compressed air tank adapted to store compressed air supplied from a combustion chamber of the deactivation cylinder, a compressed air storage passage formed to communicate the compressed air tank with the combustion chamber of the deactivation cylinder, an intake manifold selectively communicating with the compressed air tank, and a compressed air valve selectively opening/closing the compressed air storage passage, in which compressed air may be transmitted from the combustion chamber of the deactivation cylinder to the compressed air tank as the compressed air valve is opened in a compression stroke during deactivation of the deactivation cylinder.

Abstract translation: 向作为进气的燃烧室供给压缩空气的增压发动机可以包括至少两个气缸，一个停用气缸，其至少是一个气缸，并且选择性地停用;一个压缩空气罐，适于储存从燃烧室供应的压缩空气 所述停用气缸，形成为将所述压缩空气罐与所述停用气缸的燃烧室连通的压缩空气存储通道，选择性地与所述压缩空气罐连通的进气歧管和选择性地打开/关闭所述压缩空气存储通道的压缩空气阀 ，其中在停用气缸停用期间，当压缩空气阀在压缩冲程中打开时，压缩空气可以从停用气缸的燃烧室传递到压缩空气罐。
