摘要:
Embodiments of a rolling-shutter imaging system with synchronized scanning illumination and methods for higher-resolution imaging are generally described herein. In some embodiments, the imaging system includes a focal plane array (FPA) and a read-out integrated circuit (ROIC) configured to activate only a portion of the FPA during an integration time. The imaging system also includes a scanner synchronized with the ROIC to illuminate only a portion of a sensor field-of-view (FOV) of the FPA within a scene that corresponds to at least the activated portion of the FPA. The imaging system may also include beamforming optics to generate a beam of light to illuminate the portion of the sensor FOV corresponding to portion of the FPA that is activated.
摘要:
Methods and systems for separating fuel and supplying the separated fuel to an engine are disclosed. In one example, alcohol is separated from a blend of alcohol and gasoline. The methods and systems may improve fuel separator operation by adjusting separator operation in response to engine operating conditions.
摘要:
Boosted engine operation and spark timing of an engine may be adjusted with alcohol content of the fuel in a direct injection engine. Further, various adjustments may be performed in numerous related systems to account for increased maximum engine torque, such as traction control, transmission shifting, etc.
摘要:
As one embodiment, a method of operating an engine of a vehicle is provided wherein the engine has a variable engine output. The method comprises during a first engine output, delivering a first fuel to at least a cylinder of the engine via a first injector and directly injecting a second fuel directly into said cylinder via a second injector; and during a second engine output lower than said first engine output, delivering said first fuel to said at least a cylinder of the engine via said first injector and directly injecting at least a purging substance via said second injector based on an idle period since a previous injection by said second injector.
摘要:
In an apparatus comprising a fuel tank, an internal combustion engine, and a separator positioned fluidically between the fuel tank and the internal combustion engine, a method of operating the apparatus is disclosed, wherein the method comprises inputting a mixed fuel containing a hydrocarbon component and an oxygenated component into the separator, separating the fuel in the separator into a hydrocarbon-enriched fuel fraction and an oxygenated fuel component-enriched fuel fraction, and controlling an amount of the hydrocarbon-enriched fuel fraction and an amount of the oxygenated fuel component-enriched fuel fraction provided to the engine based upon an engine operating condition.
摘要:
A method of controlling fuel supplied to an engine of a vehicle is provided. The method may improve engine starting during cold operating conditions. In one example, the type of fuel injected to the engine is changed in response to operating conditions.
摘要:
A system for an engine, comprising of a cylinder of the engine; a first injector configured to inject a first substance to said cylinder; a second injector configured to inject a second substance to said cylinder; and a controller configured to commence combustion in the engine by injecting fuel into said cylinder, where said fuel is injected by only one of said first and second injectors during said start and/or warm-up.
摘要:
A system for an engine, comprising of a cylinder located in the engine, a first port injector for injecting a first fuel into said cylinder, and a second injector outside said cylinder for injecting a second fuel into said cylinder.
摘要:
A method of controlling fuel supplied to an engine of a vehicle is provided. The vehicle includes a first fuel storage tank to store a first type of fuel, a second fuel storage tank to store a second type of fuel, and an emissions control device. The engine includes at least one cylinder having a direct injection fuel injector being selectively supplied with the first type of fuel from the first fuel storage tank and the second type of fuel from the second fuel storage tank. The method includes supplying the first type of fuel from the first fuel storage tank to the direct injection fuel injector in response an engine start condition of the vehicle, and supplying the second type of fuel from the second fuel storage tank to the direct injection fuel injector, in response to an increase in engine output exceeding a threshold increase or a temperature of the emissions control device exceeding a threshold temperature.
摘要:
A variable camshaft drive system for an internal combustion engine includes a primary camshaft phaser interposed between the engine crankshaft and a first camshaft. A secondary camshaft phaser determines the phase relationship between the first camshaft and a second camshaft driven by the first camshaft and which is located on the same bank of cylinders as the first camshaft. The operation of each phaser is controlled by an electronic controller which samples one or more engine operating parameters.
