摘要： The present invention relates to a fuel system for an internal combustion engine, and a method to increase vaporization temperature of a fuel in the fuel system, which fuel system comprises a fuel tank, a fuel pump, a fuel filter device arranged downstream of the fuel pump, a first fuel conduit through which the fuel pump is arranged to supply fuel through the fuel filter device. A control valve, which opens and/or closes at a pre-determined pressure arranged upstream of the fuel filter device and downstream of the fuel pump, and a check valve arranged upstream of the fuel pump to prevent the fuel from flowing back to the fuel tank. A pressure, which is less than the pre-determined opening pressure of the control valve, is built up in the fuel pump after the internal combustion engine is turned off, for increasing vaporization temperature for hot start of the vehicle.

摘要： An injection device for an internal combustion engine includes a fuel delivery pump and a high-pressure pump which are connected to one another via a low-pressure fuel line. A high-pressure accumulator is connected to the high-pressure pump. At least one injector is connected via a high-pressure fuel line to the high-pressure accumulator. The injection device also has at least one fuel return line which is connected to the high-pressure accumulator and/or to the at least one injector. The fuel return line issues into the low-pressure fuel line which connects the fuel delivery pump and the high-pressure pump to one another. At least one air bleed valve is arranged in the course of the low-pressure fuel line or on the high-pressure pump or on a filter housing.

摘要： When a state where a lowered amount of a detection value of high-pressure side fuel pressure with respect to target fuel pressure is at least equal to a specified lowering determination value at least continues for a specified lowering determination time, a pump high-temperature determination is set “ON”. In the case where the pump high-temperature determination is set “ON”, boost control for increasing pressure of fuel that is supplied from a feed pump to a high-pressure pump (a set value of feed pressure) from a low-pressure set value to a high-pressure set value is executed.

摘要： A system according to the principles of the present disclosure includes a pump control module and a fuel vaporization module. The pump control module controls a first pump to deliver fuel from a fuel tank to a second pump through a fuel line. The pump control module controls the second pump to pressurize fuel from the fuel line and to deliver the pressurized fuel to a fuel rail. The fuel vaporization module determines whether fuel at an inlet of the second pump is vaporizing based on an engine operating condition. The pump control module increases an output of the first pump when fuel at the inlet of the second pump is vaporizing.

摘要： A valve device is attached to a fuel tank. The valve device includes a case including a vent valve port communicating outside of the tank at an upper portion, and including an inflow portion for a fuel below the vent valve port; and an upper floor body inside the case and rising by the fuel flowing into the case to be seated in the vent valve port. In a face portion facing a bottom portion of the upper float body in the case, an elastic piece is formed by a first arc-shaped split groove such that a center side of the face portion becomes a curvature inner side, and a second arc-shaped split groove formed such that a center of the face portion becomes a curvature inner side outside the first arc-shaped split groove. One portion of the elastic piece abuts against the bottom portion of the upper float body.
