Patent number: 10364769Abstract: Systems and methods utilize a controller configured to perform a diagnostic routine for a combustion seal provided between a gasoline direct injection (GDI) fuel injector and a combustion chamber of a cylinder of a GDI engine. The diagnostic routine comprises determining one of (i) a period for the injector coil current to reach a peak current and (ii) a resistance of the injector coil while the injector coil current is saturated, determining whether the determined period or the determined injector coil resistance is greater than a respective threshold indicative of a predetermined temperature of the injector coil, and when the determined period or the determined injector coil resistance is greater than its respective threshold, detecting a combustion seal leak fault. Based on the combustion seal leak fault, the controller may modify operation of the engine to prevent potential heat damage to the engine.Type: GrantFiled: November 8, 2017Date of Patent: July 30, 2019Assignee: FCA US LLCInventors: Louai A Faied, Alan G Falkowski

Patent number: 10094337Abstract: A dual path exhaust gas recirculation (EGR) system for an engine includes a common EGR intake path and first and second low pressure EGR paths including respective first and second EGR valves. The common EGR intake path is connected to the exhaust system downstream of a catalyst and includes an EGR cooler. The first EGR path is coupled directly to the EGR cooler and an inlet of a turbocompressor. The second EGR path is coupled directly to the EGR cooler and the intake system, thereby bypassing the turbocharger and an engine throttle valve. The engine includes an absence of any high pressure EGR path and the EGR valves are controlled such that the first EGR valve is closed and the second EGR valve is open at low engine speed and load operating conditions thereby providing EGR directly to the intake system that bypasses the turbocharger and throttle valve.Type: GrantFiled: March 7, 2016Date of Patent: October 9, 2018Assignee: FCA US LLCInventors: Nicolas Massard, Alan G Falkowski, Thomas G Lawrence, Massimo Fulfaro

Patent number: 7021273Abstract: A process for enabling cylinder deactivation in a multiple displacement engine involving oil aeration includes detecting engine speed. Once the engine speed has been determined, a delay period is established prior to enabling cylinder deactivation. The delay period is a function of whether engine speed exceeds a preselected threshold and an amount by which the threshold is exceeded. When the delay period expires, a request is generated for cylinder deactivation.Type: GrantFiled: March 23, 2005Date of Patent: April 4, 2006Assignee: DaimlerChrysler CorporationInventors: Michael J Prucka, Michael A Bonne, Alan G Falkowski, Mark J Duty, Mark R.
