Patent number: 10422258Abstract: Provided is a PCV valve assembly that includes a fluidic geometry that allows for the flow of combustion fluid/gas to flow between an inlet and an outlet and switch between two modes of operation, (i) a radial or high flow mode, and (ii) a tangential or low flow mode, as dictated during the operation of the engine. At low vacuums, the fluidic equipped PCV valve assembly has been tuned to operate in the radial mode producing high flow rates due to low flow resistance. As vacuum increases, the PCV valve assembly is tuned to automatically switch modes. This may be enabled due to the shape of the fluidic geometry and the bypass channel which is adapted to vary the amount of flow between a first and a second control ports. The bypass channel allows the geometric fluidic pattern to switch between the high flow mode and the low flow mode.Type: GrantFiled: March 23, 2018Date of Patent: September 24, 2019Assignee: dlhBOWLES, Inc.Inventors: Shridhar Gopalan, Jerry Thurber

The method includes obtaining engine data and determining temperature and pressure within a cylinder in response to engine data; determining crank angle resolved flame velocity evolution based on the engine data; comparing the crank angle resolved flame velocity to predetermined turbulent combustion regime data to determine a misfire occurrence; and updating a misfire occurrence indicator and outputting a control signal when the misfire occurrence indicator is greater than a predetermined limit, the control signal being capable of adjusting any engine actuators, such as external ignition source, of the spark-ignited engine on a cycle to cycle basis. The method and apparatus further includes correlating the crank angle resolved flame velocity to combustion phasing when the misfire occurrence indicator is less than the predetermined limit.Type: GrantFiled: May 13, 2016Date of Patent: September 24, 2019Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Anna G.

Patent number: 10422294Abstract: A method for regulating a fuel delivery system without a pressure sensor. The fuel delivery system has a fuel delivery pump, an electric motor, and an evaluation unit. The fuel delivery pump is driven by the electric motor, which is actuated using control variables such that a prespecifiable fuel delivery is achieved. At least two different submethods are executed for ascertaining control variables, which are ascertained in the respective submethod and are supplied to an evaluation unit. The control variables are evaluated regarding their plausibility in the evaluation unit and the electric motor is actuated based on the ascertained control variables from only one or a plurality of submethods.Type: GrantFiled: April 25, 2016Date of Patent: September 24, 2019Assignee: Continental Automotive GmbHInventor: Gerald Behrendt

Patent number: 10422295Abstract: A filter malfunction determination apparatus includes a calculator that calculates, upon determination that a rapid output increase has occurred, an amount of change of a parameter value output from a sensor before and after the rapid output increase. The calculator calculates, based on the calculated amount of change, a correction value for correcting at least one of the parameter value output from the sensor and a malfunction determination threshold. The filter malfunction determination apparatus includes an offset corrector configured to perform, based on the correction value, offset correction of at least one of the parameter value output from the sensor and the malfunction determination threshold after determination that the rapid output increase has occurred.Type: GrantFiled: June 30, 2016Date of Patent: September 24, 2019Assignee: DENSO CORPORATIONInventors: Masahiro Yamamoto, Manabu Yoshidome, Masayuki Tamura, Go Miyagawa

Patent number: 10422297Abstract: This method of injection management in a direct-injection engine involves shifting from a so-called single-injection mode (Init 1 pulse), in which the major portion of the quantity of fuel injected during a combustion cycle is injected in one go, to a so-called multi-injection mode (MPL active), in which several successive injections are carried out in order to inject fuel during a combustion cycle, and vice versa. The multi-injection mode is chosen when a condition based on one or more parameter(s) of the engine is fulfilled (MPL cdn ok). The multi-injection mode is limited to a predefined time interval (Tact_MPL_max) even if, at the end of the interval, the condition for adopting the multi-injection mode is still fulfilled.Type: GrantFiled: July 14, 2016Date of Patent: September 24, 2019Assignees: CONTINENTAL AUTOMOTIVE FRANCE, CONTINENTAL AUTOMOTIVE GMBHInventors: Philippe Serrecchia, Jean-Luc Fremaux
