TLDR
In this article, an embodiment of the invention includes an exhaust gas recirculation (EGR) valve, an intake pipe, and an afterburner, which captures and burns large particles contained in the exhaust gas stream to prevent obstruction of the EGR valve.Abstract:
An embodiment of the invention includes an exhaust gas recirculation (EGR) valve, an intake pipe, and an afterburner. As the intake valve communicates an exhaust gas stream to an EGR valve, an afterburner affixed to an inside wall of the intake pipe captures and burns large particles contained in the exhaust gas stream to prevent obstruction of the EGR valve.read more

Engine oil leak test system and method
TL;DR: In this paper, a system and a method for testing partially assembled engines for possible oil leaks is presented, which includes engine pressurizing devices that are automatically controlled by a controller according to a predetermined control program.
Patent
An exhaust system for an internal combustion engine provided with an exhaust gas recirculation circuit
TL;DR: In this article, an exhaust system for an internal combustion engine is described, which is provided with a feeding pipe (5) of fresh air to an intake manifold (3) and with a turbocharger (16) arranged along the feeding pipe.
Patent
Engine oil leak test method with EGR valve leak offset
TL;DR: In this paper, a method for pressure testing an engine to detect possible oil seal leaks was proposed, where the engine was charged with a predetermined pressure while air pressure was also applied to an exhaust gas recirculation (EGR) valve intake port to offset leakage inherent in the EGR valve.
