Patent number: 11708811Abstract: Methods and systems are provided for restarting an engine following an engine idle-stop. In one example, a method may include, prior to an engine restart following an idle-stop, adjusting a spark ignition timing based on an estimation of a fuel-air equivalence ratio (phi) and an estimation of a cylinder turbulence.

Patent number: 9353756Abstract: The subject of the invention is a method for the controlling and feeding of power plants, in particular coal fired power plants comprising a steam turbine connected to a turbogenerator. The method consists in that in periods of low power consumption the power is transferred from the turbine shaft to a compressor and the air compressed therein is pumped by compressors to the tanks of a compressed air terminal until a pressure close to the pressure of steam fed to turbine blades is reached. When energy demand increases, compressed air from the tanks is fed through nozzles onto the turbine blades along with superheated steam produced in a boiler. The subject of the invention is also a system for collecting compressed air and feeding it to the turbine.Type: GrantFiled: September 27, 2012Date of Patent: May 31, 2016Inventors: Waldemar Piskorz, Tomasz Tadeusz Piskorz

Patent number: 6866015Abstract: To prevent the entry of ambient air and liquid such as rainwater into a direct acting type auto-by starter and thereby prevent the formation of rust in the auto-by starter, by adjusting pressure fluctuations in the auto-by starter caused by the operation of a starting valve for opening and closing a starting intake passage. A starting valve is lifted to open a starting intake passage to start an internal combustion engine. Pressure in a sliding space for the starting valve is increased, so that the gas in the sliding space flows out. The flow of the gas is absorbed by an increase in volume inside a bellows boot mounted on an upper portion of the starting valve. When the starting valve is lowered by the operation of a spring member, the pressure in the sliding space is reduced to allow the gas flow from the bellows boot into the sliding space.Type: GrantFiled: July 1, 2003Date of Patent: March 15, 2005Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Akinobu Masunaga, Kazuhito Hotta

Patent number: 6778076Abstract: An oil pressure switch failure detection system for an outboard motor, having a first oil pressure switch which generates an ON signal indicating that the oil pressure is less than or equal to a first predetermined oil pressure and a second oil pressure switch which generates an ON signal indicating that the oil pressure is less than or equal to a second predetermined oil pressure which is set higher than the first predetermined oil pressure. In the system, by discriminating whether the generated signals of the first and second oil pressure switches are equal to be expected signals expected under operating conditions of the engine, it is determined whether at least one of the first and second oil pressure switches fails. With this, it become possible to detect failure of the first and second oil pressure switches, accurately.Type: GrantFiled: December 28, 2001Date of Patent: August 17, 2004Assignees: Honda Giken Kogyo Kabushiki Kaisha, Keihin CorporationInventors: Sadafumi Shidara, Nobuhiro Takahashi
