F02M 26/50

Abstract:

Aspects of the disclosure relate to providing an EGR cooler including a barrier layer applied to EGR cooler components while allowing sufficient heat transfer between exhaust gases and the cooling medium. A barrier layer may be applied onto particular surfaces of the EGR cooler components to prevent deposition of hydrocarbons or soot on the EGR cooler components. In some arrangements, the barrier layer may comprise a refractory solid oxide. In other arrangements, an EGR cooler may comprise a catalytic barrier layer. The catalytic barrier layer may include a refractory solid oxide and a platinum group metal or mixed metal oxide to prevent accumulation of varnish material deposited onto EGR cooler components.

Abstract:

A method of boosting air to an intake manifold () of an engine () having cylinders (C) that emit exhaust gas includes the steps of dividing the exhaust gas emitted from the cylinders into a first exhaust passageway (A) and a second exhaust passageway (B), and fluidly communicating at least a portion of the exhaust gas (EG) from the first exhaust passageway to a divided turbocharger (). The method also includes the steps of fluidly communicating at least a portion of the exhaust gas (EG) from the second exhaust passageway (B) to the divided turbocharger (), and fluidly communicating the exhaust gas from the divided turbocharger to an undivided turbocharger (). Further steps in boosting the air include compressing air (CA) at a compressor () of the undivided turbocharger (), and fluidly communicating the compressed air to the intake manifold ().
