INTAKE MANIFOLD

摘要

An intake manifold comprising an intake gas duct, an EGR duct, an EGR flow measurement system, and a mixing duct. The intake gas duct allows the fresh intake gas to flow therethrough. The EGR flow measurement system defines a portion of an EGR duct and measures a differential pressure of the recirculated exhaust gas passing through the EGR flow measurement system. The mixing duct is positioned downstream of the intake gas duct, and it is also positioned downstream of the EGR duct. The mixing duct, which is integrally formed into the EGR flow measurement system, mixes the fresh intake gas and the recirculated exhaust gas into a mixed intake gas.

1. An intake manifold, comprising:
an intake gas duct configured to allow a fresh intake gas to flow therethrough; an exhaust gas recirculation (“EGR”) duct; an EGR flow measurement system defining a portion of the EGR duct and configured to measure a differential pressure of a recirculated exhaust gas passing therethrough; and a mixing duct being positioned downstream of the intake gas duct relative to a direction of the fresh intake gas flow and also being positioned downstream of the EGR duct relative to a direction of the recirculated exhaust gas flow, the mixing duct configured to mix the fresh intake gas and the recirculated exhaust gas into a mixed intake gas, the mixing duct being integrally formed into the EGR flow measurement system.
