摘要： Managing firing fraction transitions of a variable displacement internal combustion engines by (a) avoiding transport delays in an Exhaust Gas Recirculation (EGR) feed by starting movement of an EGR valve position after a decision to transition to a new firing fraction has been made, but prior to the start of the transition and (b) adjusting the EGR valve as needed during the transition so as to maintain an EGR fraction within a predetermined range during the transition. By performing both (a) and (b), spikes of nitrous oxide (NOx) and/or hydrocarbon emissions are reduced or altogether eliminated during the transition.

摘要： A fuel system includes a fuel pump having an inlet and an outlet. The fuel system also includes a jet pump assembly having a first fuel passage defined by a first tube, the first fuel passage having a first fuel passage inlet and a first fuel passage outlet; and a second fuel passage defined by a second tube and connected to the outlet of the fuel pump, the second fuel passage having an exit orifice which discharges a first flow into the first fuel passage which draws a second flow into the first fuel passage through the first fuel passage inlet such that the first flow and the second flow combine in the first fuel passage and exit the first fuel passage through the first fuel passage outlet. The second fuel passage also has an initial orifice arranged upstream from, and in series with, the exit orifice.

摘要： A handheld work apparatus includes a gas-operated combustion engine which has a cylinder with a combustion chamber, the combustion chamber being delimited by a piston. The combustion engine is fed combustion air via an intake channel and liquid gas via a supply line. The liquid gas enters into an opening of the supply line in a gas tank, it being possible for the position of the opening of the supply line in the gas tank to be adjusted. A longitudinal section of the supply line lies within the gas tank and is formed from a flexible hose. A weight is arranged in the region of the opening in such a way that liquid gas is fed via the opening to the supply line of the mixture formation unit in every operating position of the work apparatus.

摘要： A vehicle includes a fuel tank, a jet pump and a controller. The fuel tank has a passive side and an active side. Each of the sides includes a fuel level indicator. The jet pump is disposed within the active side and is configured to maintain a fuel level above a first threshold, based on each of the indicators, on the active side by siphoning fuel from the passive side during operation in a combustion mode. The controller is configured to, in response a battery charge level being below a second threshold during operation in an electric mode and a detected hill climb via a route guidance system, activate the jet pump to siphon fuel such that a fuel level within the active side rises above the first threshold.

摘要： A suction head for connection to a fuel hose in a fuel tank has a base member made of an injection molding material. The base member has a peripheral wall surface provided with cutouts and also has an end face opening. A cap closes off the end face opening. A connecting socket for the fuel hose is provided on the suction head. A first filter element is received inside the base member. A second filter element covering the cutouts is provided and is made of a filter fabric, wherein the filter fabric is a twill weave fabric or a satin weave fabric. The filter fabric has a mesh size that is greater than 10 μm and smaller than 25 μm. A power tool with a four-stroke engine is provided with such a suction head in the fuel tank.

摘要： A swirling wall structure-extends from a lower side toward an upper side in a sub-tank, and a fuel flow, which is outputted into an inside of the sub-tank from a flow outlet of a diffuser passage opened toward a lateral side, is swirled by the swirling wall structure. The swirling wall structure-includes a curved wall surface and a U-turn wall surface. The curved wall surface is curved about a longitudinal axis, which extends from the lower side toward the upper side in the sub-tank, to bend the fuel flow outputted from the flow outlet. The U-turn wall surface extends continuously from the curved wall surface to make a U-turn of the fuel flow, which is bent by the curved wall surface.
