Abstract: PURPOSE: A separable intake manifold apparatus for stratifying Exhaust Gas Recirculation in an engine is provided to simultaneously reduce nitrogen oxide and soot by stratifying re-circulated EGR gas in a combustion chamber. CONSTITUTION: A separable intake manifold apparatus for stratifying Exhaust Gas Recirculation in an engine comprises multiple cylinders(3), intake manifolds(5), EGR pipes(7), and EGR valve units. Each cylinder comprises multiple intake ports(1). The intake manifolds connect the intake ports of each cylinder to form an air path. The EGR pipes are connected to the intake manifolds. The EGR valve units control the amount of EGR gas supplied from the EGR pipes to the intake manifolds.
Abstract translation: 目的：提供一种用于分级发动机中的排气再循环的可分离的进气歧管装置，以通过在燃烧室中分层再循环的EGR气体来同时减少氮氧化物和烟灰。 构成：用于分级发动机中的废气再循环的可分离的进气歧管装置包括多个气缸（3），进气歧管（5），EGR管（7）和EGR阀单元。 每个气缸包括多个进气口（1）。 进气歧管连接每个气缸的进气口以形成气道。 EGR管连接到进气歧管。 EGR阀单元控制从EGR管供给到进气歧管的EGR气体的量。
