Patent number: 9810166Abstract: Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency or the engine.Type: GrantFiled: March 20, 2017Date of Patent: November 7, 2017Assignee: Massachusetts Institute of TechnologyInventors: Daniel R. Cohn, John B. Heywood, Leslie Bromberg

Patent number: 9810161Abstract: A diagnostic system for a vehicle includes a difference module, a Fourier module, and a fault module. The difference module determines pressure differences for a camshaft revolution based on differences between: first pressures within first chambers of a camshaft phaser measured during the camshaft revolution, wherein the first pressures within the first chamber control advancement of the camshaft relative to a crankshaft of an engine; and second pressures within second chambers of the camshaft phaser measured during the camshaft revolution, wherein the second pressures within the second chamber control retardation of the camshaft relative to the crankshaft of the engine. The Fourier module performs a Fourier Transform (FT) based on the pressure differences to produce FT data. The fault module, based on the FT data, selectively indicates that a fault is present in a variable valve lift mechanism that is actuated by the camshaft.Type: GrantFiled: December 9, 2014Date of Patent: November 7, 2017Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Victor A.

Patent number: 9803612Abstract: A cylinder-inflow EGR gas amount is estimated, a misfire limit EGR gas amount is calculated on the basis of an engine operation state, and the misfire limit EGR gas amount is compared with the cylinder-inflow EGR gas amount to predict whether a misfire occurs. When the misfire is predicted, a misfire avoidance control is executed. Further, an actual misfire countermeasure effect amount in a case of the execution of the misfire avoidance control is calculated, and the actual misfire countermeasure effect amount is compared with a required misfire countermeasure effect amount to determine whether the misfire is avoidable when the misfire avoidance control is executed. If the misfire is unavoidable even if the misfire avoidance control is executed, a delay restriction value of an ignition timing to avoid the misfire is calculated, and the amount of a delay in the ignition timing is restricted using the delay restriction value.Type: GrantFiled: April 17, 2014Date of Patent: October 31, 2017Assignee: DENSO CORPORATIONInventors: Keitarou Minami, Hideaki Ichihara, Hiroyuki Takezoe, Hiroshi Katsurahara

Patent number: 9803571Abstract: A method, used with dual-fuel engine, of controlling the amount of gaseous fuel delivered to the engine. At operating conditions that result in an equivalence ratio below a predetermined threshold (which typically occur at mid or part loads), it is determined whether better performance and/or lower emissions can be achieved by reducing gaseous fuel to some cylinders and increasing gaseous fuel to others. Typically, the gaseous fuel is reduced to zero to a number of cylinders and increased to others, with the increase resulting in an equivalence ratio that will provide improved emissions and efficiency and the desired engine output.Type: GrantFiled: January 23, 2016Date of Patent: October 31, 2017Assignee: SOUTHWEST RESEARCH INSTITUTEInventors: John C. Hedrick, David P. Branyon, Timothy J. Callahan, Jeremy D. Eubanks, Ryan C. Roecker, Garrett L. Anderson

Patent number: 9797362Abstract: A starter control apparatus outputs a conduction command to a starter relay when an engine start request is generated and starts driving of a starter. After the engine is started, when a condition for executing the failure diagnosis processing is satisfied, the starter control apparatus outputs a non-conduction command to a starter cutoff relay and diagnoses the starter cutoff relay for failure. The starter control apparatus determines that the starter cutoff relay is normal when a voltage applied to the starter after notification of the non-conduction command to the starter cutoff relay does not exceed a predetermined voltage. The starter control apparatus determines that the starter cutoff relay is abnormal when the voltage applied to the starter exceeds the predetermined voltage.Type: GrantFiled: May 9, 2016Date of Patent: October 24, 2017Assignee: DENSO CORPORATIONInventor: Kouji Nagata
