Patent number: 9689322Abstract: A vehicle includes an engine having cylinders in fluid communication with an intake air flow, a mass air flow (MAF) sensor positioned with respect to the intake air flow which outputs a pulse train signal describing the frequency of the intake air flow, and a controller. The controller includes a calibrated non-linear conversion curve recorded in memory. The controller executes a method to convert the frequency data into a corresponding mass air flow using the calibrated non-linear conversion curve, determines the instantaneous mass air flow value at each leading or trailing edge of the pulse train signal, and accumulates the instantaneous mass air flow values over a calibrated duration. A time-weighted average of the accumulated mass air flow values is then used to execute a control action. The controller includes a host computer device and memory storing the curve and instructions for executing the method.Type: GrantFiled: March 14, 2013Date of Patent: June 27, 2017Assignee: GM Global Technology Operations LLCInventors: Yun Xiao, Chad E.

Patent number: 9689325Abstract: A purge pump is installed in a purge conduit, which forms a purge passage that communicates between an inside of a canister and an air intake passage. When a pressure of the air intake passage is equal to or smaller than a predetermined pressure, a large quantity of evaporative fuel, which is larger than a predetermined purge quantity, is introduced into the air intake passage. At this time, a pump electric power supply device supplies a relatively small amount of the electric power to the purge pump to run the purge pump. When the pressure of the air intake passage is larger than the predetermined pressure, the purge pump is driven to pump the evaporative fuel into the air intake passage. At that time, the pump electric power supply device supplies a relatively large amount of the electric power to the purge pump.Type: GrantFiled: March 30, 2015Date of Patent: June 27, 2017Assignee: DENSO CORPORATIONInventor: Kunio Nanba

Patent number: 9689326Abstract: The present disclosure provides for a vehicle engine having an EGR system where pairs of cylinders are directly connected to each other. For example, a first and second cylinder may be operably connected by a valve actuator where a high energy, blowdown exhaust gas from the first cylinder may flow through a first flow path directly from the first cylinder to the second cylinder. Likewise, during the firing stroke of the second cylinder, a high-energy, blowdown exhaust gas may flow from the second cylinder through a second flow path directly into the first cylinder. This arrangement may pair cylinders to take advantage of high-energy exhaust gas.Type: GrantFiled: June 4, 2015Date of Patent: June 27, 2017Assignees: Hyundai America Technical Center, Inc., Hyundai Motor Company, Kia Motor CorporationInventor: Nayan Engineer

Patent number: 9689327Abstract: In one aspect, a method for controlling operation of an internal combustion engine is described. The engine is operated in a skip fire manner such that selected skipped working cycles are skipped and selected active working cycles are fired to deliver a desired engine output. A particular level of torque output is selected for each of the fired working chambers. Various methods, engine controllers, arrangements and systems related to the above method are also described.Type: GrantFiled: October 21, 2015Date of Patent: June 27, 2017Assignee: Tula Technology, Inc.Inventors: Matthew A. Younkins, Louis J. Serrano
