An air exhaust mixer assembly includes an upstream intake section with an upstream elbow and a downstream elbow. A mixing tube is configured to introduce exhaust gas into the upstream intake section at a location upstream of the downstream elbow. An internal combustion engine utilizing the air exhaust mixer assembly is also provided.

Mixing system for engine with exhaust gas recirculation

An internal combustion engine includes a plurality of combustion cylinders, at least one turbocharger, an air supply line, an exhaust gas line and an exhaust gas recirculation system. An exhaust manifold of the exhaust gas line may have both non-direction specific and modular pulse exhaust manifold elements. If the internal combustion engine has dual cylinder banks, an exhaust gas balance tube may extend between exhaust gas lines of the cylinder banks and be fluidly connected to an exhaust manifold between the ends thereof.

Internal combustion engine with improved exhaust manifold

A device for separating gas from liquid includes a housing having an inlet for receiving a flow of liquid and gas. The inlet is positioned such that the flow of liquid and gas enters the housing in a direction substantially tangential to a circumference of an inner surface of the housing. The housing also includes a first outlet for discharging an at least partially gaseous flow from the housing and a second outlet for discharging an at least partially deaerated flow of liquid from the housing. The device also includes a gas separating element disposed inside the housing downstream from the inlet and upstream from the second outlet. The gas separating element forms at least one opening to permit liquid to pass and form the at least partially deaerated flow and to permit the at least partially gaseous flow to separate from the at least partially deaerated flow.
