Publication number: 20170016409Abstract: A heat-ray type of airflow meter has a signal processor for converting a detected intake air quantity into a frequency signal. An engine controller has a conversion table for converting the frequency signal into an air quantity. The signal processor and the conversion table have features such that the frequency increases as the magnitude of a positive air quantity increases, and the frequency decreases as an absolute value of a negative air quantity increases. In the conversion table, a prescribed positive air quantity value is assigned a dummy output for frequencies lower than a prescribed threshold value. Under normal circumstances, frequencies lower than a minimum value are not used. The frequency decreases to near 0 Hz when there is a disconnection or a short circuit, the dummy output is therefore output, and an injection quantity equal to or greater than a misfire limit is ensured.Type: ApplicationFiled: January 26, 2015Publication date: January 19, 2017Inventors: Yukinobu ITO, Yukimi MIZUNO

Publication number: 20170016410Abstract: An engine operation control apparatus and engine operation control method of a vehicle are provided. The engine operation control apparatus includes a coolant temperature sensor that detects a coolant temperature of a coolant line which passes through an engine. Further, the apparatus includes first and second maps in which corresponding engine operating points are mapped to a vehicle speed, a gear stage, a driver requesting torque, and an electric field load amount of the vehicle. A controller determines a candidate operating point using any one of the first and second maps based on a comparison between the coolant temperature and a predetermined threshold value and determines an optimal operating point of the engine using the candidate operating point.Type: ApplicationFiled: October 24, 2015Publication date: January 19, 2017Inventors: Yong Kak Choi, Hyungseuk Ohn, Minseok Song, Dong Jun Shin

Publication number: 20170016411Abstract: The Thermal Compression Engine is an external combustion engine using a regenerator to achieve cycle efficiency. The Thermal Compression Engine uses thermal compression (heat addition resulting in pressure rise) rather than mechanical. By alternating flow into a constant volume, of hot and then cold fluid creates pressure rise and fall in the working fluid. This fluctuating pressure generates a reservoir of high, and a reservoir of low pressure fluid. The TCE cycle uses the high and low pressure storage to generate a fluid flow, with expansion through a turbine or other expansion device, to generate power.Type: ApplicationFiled: September 9, 2015Publication date: January 19, 2017Inventor: Gerald J.

Publication number: 20170016414Abstract: Devices for producing vacuum using the Venturi effect are disclosed that have a motive passageway converging toward a suction chamber, a discharge passageway diverging away from the suction chamber, and a suction passageway, all of which are in fluid communication with the suction chamber. The motive passageway has a single entrance, and subdivides downstream thereof into a plurality of subpassageways, one each leading to one of the plurality of motive exits, which are spaced apart from a discharge entrance of the discharge passageway to define a Venturi gap. The fletch having a plurality of ribs extending between an exterior surface of the generally conically-shaped main body thereof and an interior surface of the motive passageway is disposed in the motive passageway. The ribs divide the motive passageway into the plurality of sub-passageways, each converging fluid flow over the exterior surface thereof toward one of the plurality of motive exits.Type: ApplicationFiled: July 14, 2016Publication date: January 19, 2017Applicant: Dayco IP Holdings, LLCInventors: David E.
