The device includes an inner pressure sensor configured to detect a pressure in an interior space of the fuel tank, a valve-opening start position determination means configured to change the stroke amount of a flow control valve from an initial condition and to determine a valve-opening start position of the flow control valve based on a requirement that a range of variation of the inner pressure is equal to or greater than a predetermined value, a learning means configured to store the valve-opening start position, and a prohibition means configured to prohibit the valve-opening start position determination means from determining the valve-opening start position when the inner pressure falls within a predetermined pressure range relative to the atmospheric pressure. | 2017-10-05 |
20170284318 | SYSTEMS AND METHODS FOR REDUCED OIL CARRYOVER - A system in one embodiment includes at least one cylinder, a supplemental boost supply, and a supply line. The at least one cylinder is configured for use in a reciprocating internal combustion engine, and includes a combustion portion and a crank portion on opposite sides of a piston. The at least one cylinder also includes an intake port and an exhaust port in fluid communication with the combustion portion. The supplemental boost supply is configured to provide a supplemental air supply to the combustion portion of the engine when the engine is idling to increase pressure in the combustion portion. The supply line couples the supplemental boost supply to the intake port. | 2017-10-05 |

20170284320 | IGNITION SYSTEM FOR INTERNAL COMBUSTION ENGINES - A method for operating a spark ignited gaseous fuel internal combustion engine is disclosed. The engine may have at least one main combustion chamber and at least one ignition device configured to initiate an ignition event within an ignition region. The method may include supplying pressurized fuel to the ignition region at times between about 30° to about 0° crank angle before the ignition event is initiated by the ignition device for enriching the ignition region with fuel. The method may also include initiating an ignition event in the ignition region for combusting an enriched air/fuel mixture within the ignition region. | 2017-10-05 |
