A shield for a diesel exhaust fluid injector is mounted horizontally in an opening in a side wall of an exhaust gas aftertreatment system of an internal combustion engine. The diesel exhaust fluid injector configured to inject diesel exhaust fluid in a direction generally normal to the side wall into a mixer positioned in an exhaust gas stream. The shield may include a first portion extending axially and a second portion extending radially inwardly from the first portion.

Diesel exhaust fluid injection shield and diesel exhaust fluid injection system

A shield for a diesel exhaust fluid injector is mounted in an opening in a side wall of an exhaust gas aftertreatment system of an internal combustion engine. The diesel exhaust fluid injector is configured to inject diesel exhaust fluid in a direction generally normal to the side wall into a mixer positioned in an exhaust gas stream. The shield includes a first portion extending axially and a second portion extending radially inwardly from the first portion.

Engine systems and methods improve emission control through the use of concurrent HCI and EGR. An engine system includes at least two cylinders. A fuel system intermittently supplies a first fuel stream to the first cylinder and a second fuel stream to the second cylinder. An intake system supplies combustion air to the cylinders. An exhaust manifold has one or more interior chambers through which the exhaust gas from the cylinders passes. An EGR circuit is connected between the exhaust manifold and the intake system and includes an EGR valve. A controller operates the fuel system to supply the first fuel stream to deliver fuel to the exhaust system while operating the fuel system to stop the second fuel stream from delivering fuel to the exhaust system, and to open, concurrently with operating the fuel system to supply the first fuel stream, the EGR valve to supply the exhaust gas to the intake system.

Engine system and method with hydrocarbon injection and EGR

A power system including an intake gas cooler and aftercooler positioned gaseously downstream thereof. The intake gas cooler is configured to receive a fresh intake gas for combusting in an engine and a recirculated exhaust gas expelled by the engine for re-combusting therein.

Power system with an intake gas cooler

A power system including an engine, a first heat transfer circuit, and a second heat transfer circuit. The first heat transfer circuit includes a first heat exchanger that cools a first circuit fluid. The first circuit fluid cools a block and a head of the engine. The second heat transfer circuit includes a second heat exchanger that cools a second circuit fluid. The second circuit fluid cools a lube oil cooler.
