摘要： Peripheral sections of two diaphragms are stacked on each other. The peripheral sections of the two diaphragms form an outer rim of a diaphragm damper. The outer rim is continuously sealed and joined by laser welding over the entire circumference of the outer rim. The thickness of the tip of the outer rim is set in correspondence with the spot diameter of a laser beam at the tip of the outer rim. A weld bead is formed by welding in the entire area of the tip of the outer rim.

摘要： When fuel injections into Otto-engines are carried out, pressure pulsations occur in the entire fuel injection system. These prevent detailed information about the fuel injection to be deduced from the pressure signals measurable in the system. When specially designed dampers for these pressure pulsations are employed, pressure difference signals over the pulsation damper can readily be employed for instantaneous volume flow rate measurements. Furthermore, the inserted pressure pulsation dampers also allow the pressure reduction in the Common-Rail, due to the fuel injections, to be employed to measure the instantaneous fuel injection volume flow rates, in running Otto-engines. The authors' development work in this field is described in this paper and results of verification measurements are presented.

摘要： A fuel supply apparatus for a Gasoline Direct Injection (GDI) engine having reduced pressure pulsation includes low and high pressure fuel pumps, connected via a fuel supply line, a pressure sensor and a pulsation relief valve installed between the pressure sensor and the high pressure fuel pump. The pulsation relief valve includes a check valve part allowing the fuel to flow in a normal direction from the low pressure fuel pump to the high pressure fuel pump but not in a reverse direction, and an orifice part which is installed substantially in parallel to the check valve part and is configured to allow the fuel to flow in both directions, wherein an amount of the fuel flowing through the orifice part is less than an amount of the fuel flowing through the check valve part in the normal direction.

摘要： A fuel injection control system for an internal combustion engine in which a driving signal for a high pressure fuel pump is calculated by using proportional plus integral control based on a difference between a delivery pressure of the high pressure fuel pump and a target pressure thereof. A delivery pressure of a low pressure fuel pump is caused to decrease when an amount of change per unit time of an integral term shows a decreasing tendency or zero, whereas the delivery pressure of the low pressure fuel pump is caused to increase when the amount of change per unit time of the integral term shows an increasing tendency. In cases where an increase in the integral term resulting from a change in the target delivery pressure of the high pressure fuel pump has occurred, the increase in the delivery pressure of the low pressure fuel pump is prohibited.

摘要： The objective of the present invention is to provide a diaphragm damper with which the amount of volume change due to the resonance frequency and pressure can be set freely and the performance of the diaphragm damper can be optimized, without changing the attachment structure for a conventional metal diaphragm and without obstructing the space where fuel flows in a fuel chamber. To this end, this diaphragm damper, wherein a high-pressure gas is enclosed in a high-pressure chamber formed by two disk-shaped metal diaphragms the outer circumferential portions of which have been joined together, is constructed such that rubber-like elastic members are arranged within the high-pressure chamber.

摘要： A mechanism for reducing pressure pulsation includes a pair of metal dampers formed by joining two disk-shaped metal diaphragms over an entire circumference and forming a hermetically sealed space inside a joined portion. Gas is sealed in the aforementioned hermetically sealed space of the damper, and a pair of pressing members give pressing forces to both outer surfaces of the aforementioned metal dampers at a position at an inner diameter side from the joined portion. The mechanism is unitized, with the pair of pressing members being connected in a state in which they sandwich the metal damper.
