摘要： A vehicle and a method of reducing sound produced by a liquid fluid pump are disclosed. A pump is activated when a predetermined event is detected. A control valve of the pump is operated in one of an initial and a standard mode when the pump is activated. The control valve is operable to allow a gaseous fluid to vent out of the pump when in the initial mode corresponding to the pump being in a first phase. The control valve is operable to allow a liquid fluid to move through the pump when in the standard mode corresponding to the pump being in a second phase. A solenoid of the control valve is energized and de-energized, at a calibrated frequency, in a sequence when in the initial mode to reduce the sound in the pump during the initial mode.

摘要： An automobile fuel system pressurization apparatus includes an inflatable bladder having a proximal end, a distal end, an exterior surface, and an inlet accessing an interior. The inflatable bladder being deformable between an expanded state and a deflated state. In the expanded state, the exterior surface of the inflatable bladder is configured to provide an air-tight seal in a filler neck of a fuel tank. A pump is coupled to the inlet of the inflatable bladder and is configured to supply air pressure to the interior of the inflatable bladder. A pressure relief valve is disposed at the distal end of the inflatable bladder and is in fluid communication with the interior of the inflatable bladder. When the inflatable bladder is in the expanded state, the pressure relief valve is configured to release a portion of the air pressure from the interior of the inflatable bladder into the fuel tank.

摘要： The present invention relates to a method of operating an internal combustion engine. With reference to FIG. 1, fuel is supplied to charge air using an injector (116) which in each operation delivers a set amount of fuel. The amount of fuel supplied to the charge air in each engine cycle is controlled by how many times the injector (116) operates in each cycle. A desired fuel demand is calculated as a number of operations of the injector per cycle, calculated to at least one decimal place. The desired fuel demand is rounded to a near integer to provide an output fuel demand for the injector as a number of operations of the injector for the next operating cycle in varying operating conditions of the engine. In steady state operating conditions of the engine an aggregate number of operations for a plurality of engine cycles is calculated which is closer to an aggregated desired fuel demand for the plurality of cycles than if for each cycle of the plurality of output cycles the output fuel demand is calculated independently.

摘要： A micro-pulsation metering fuel injection system, comprising a throttle body and at least one injection unit. The throttle body is mounted in an inlet pipe of a cylinder of an internal combustion engine for controlling a quantity of flow of air into a combustion chamber. The injection units are mounted on the throttle body and have each a plurality of micropumps. The micropumps suck in fuel and inject tiny droplets of fuel into an air inlet inside the throttle body, so that the droplets of fuel mix with air in the throttle body, creating a mixture, which enters the combustion chamber of the cylinder. A control unit senses operating parameters of the engine and drives the injection units via a driver unit. This allows precisely to control the quantity of injected fuel and flexibly to control the distributing fuel spray, resulting in higher fuel efficiency and lore exhaust emission.
