Patent number: 10253707Abstract: Redundancy in engine timing position sensing maintains a UAV operational in the event of failure of a primary engine timing position sub-system. The redundancy avoids duplication of the primary crankshaft timing position sensing components, and avoids adding weight, cost and component complexity. Conditioned (square) waveform(s) (102) is/are created from respective sinusoidal waveform(s). Each consecutive leading edge (103a) and trailing edge (103b) of the pulses of the square waveform (102) is derived from the crossing of the zero voltage value by consecutive sinusoidal waveforms A,B,C (e.g. Voltage (V) vs Time (t) or angular degrees). The square pulse waveform (102) is output (104) to a microcontroller (106) to create and output a pseudo crankshaft timing position signal (108) to be used by an ECU to determine ignition and fuel injection events in the event that the primary timing signal from the crankshaft position sensor (CPS) has failed.Type: GrantFiled: June 23, 2015Date of Patent: April 9, 2019Assignee: ORBITAL AUSTRALIA PTY LTDInventors: Tyron Dean Utley, Nicolass Harry Buters, Jayesh Narayan

Patent number: 10227945Abstract: An optimized port plus direct injection (PFI+DI) fueling system for reducing DI-generated particulates from a spark ignition gasoline engine is disclosed. It uses information from a computational model that includes piston wetting. Means for DI particulate reduction include control of DI timing and duration as a function of various parameters. Illustrative computational results for decreasing particulates in various drive cycles are presented. These calculations illustrate large potential particulate reductions (e.g. 95%) that can be obtained relative to DI operation alone. The optimized PFI+DI system could provide DI generated particulate reduction, efficiency and cost advantages relative to operation of a DI alone engine with a gasoline particulate filter (GPF). Alternatively, it could be used in combination with a GPF to ease GPF operation requirements and provide additional particulate reduction. Techniques for reducing piston wetting generation of particles from use of DI alone are also described.Type: GrantFiled: September 25, 2017Date of Patent: March 12, 2019Assignee: Ethanol Boosting Systems, LLCInventors: Leslie Bromberg, Daniel R.
