A coaxial cable includes a coaxial wire in which an inner insulator, an outer conductor and a sheath are sequentially and coaxially provided around a center conductor, and a substrate having a surface on which a first contact pad and a second contact pad are arranged. The sheath is removed at one end portion of the coaxial wire by a predetermined length, so that the inner insulator and the outer conductor are exposed, and a tip end of the inner insulator is removed by a predetermined length, so that the center conductor is exposed. The exposed portion of the center conductor is soldered to the first contact pad with the exposed portion of the inner insulator being bent relative to the sheath, and the exposed portion of the outer conductor is soldered to the second contact pad with being bent in a direction different from the bending direction of the inner insulator. A part of the coaxial wire covered by the sheath is standing at an angle of 30&#xb0; or greater relative to the surface of the substrate.

Coaxial cable and method for manufacturing the same

The flat cable is structured such that a plurality of insulated wires with their conductors covered with insulating resin are arranged in parallel and the outer surfaces of the plurality of insulated wires are integrated. The insulating resin between two insulated wires is removed by laser beam in a soldering portion, and, among the plurality of insulated wires, only two mutually adjoining insulated wires are electrically connected to each other by soldering in the soldering portions in which the insulating resin are removed and the conductors are exposed. Such flat cable can positively solder bridge the mutually adjoining conductors.

The plural shielded electric wiresare bundled so as to make contact with the adjacent shielded electric wires, and sheathsof the plural shielded electric wiresare respectively removed at the same position in the length direction, and outer conductorsof the plural shielded electric wiresat the position at which the sheathsare removed are bundled by a metal wireand the bundled portion is soldered and fastened.

Multi-core cable

One aspect of the invention relates to a multi-core cable in which a cable sheath covers plural electronic wires in each of which a central conductor is covered with a covering. In the multi-core cable, the electronic wires are exposed from a longitudinal end of the cable sheath, and distal ends of exposed portions of the plural electronic wires are parallel aligned, and the exposed portions of the plural electronic wires are fixed by a resin in a place within a range from the end of the cable sheath to a parallel aligned place.

Multi-core cable and aligning method therefor

A first valve element () and second valve element () are arranged in a pressure switching chamber () of a three-way valve (). When switching a destination of a fuel flow passage () from a high pressure fuel feed passage () to a low pressure fuel return passage (), the state where the first valve element () is open and the second valve element () is closed is switched through a state where the first valve element () and second valve element () are both closed to a state where the first valve element () is closed and the second valve element () is open. Fuel pressure of a pressure control port () sealed by a sliding seal face () formed at an outer circumference of the second valve element () is used to control an opening timing of a needle valve ().

Fuel injection system

A pressure boosting unit () is provided in each fuel injection valve of an engine (). A pressure of fuel to be supplied to the fuel injection valve from a common rail () is boosted as required. An ECU () causes low pressure injection to be performed with the pressure boosting unitbeing in a non-operated state, and high pressure injection to be performed with the pressure boosting unit () being in an operated state, and the pressure of the fuel being maintained at a boosted pressure. Based on the result, the ECU () corrects a fuel injection period of the fuel injection valve. Also, after the correction of the fuel injection period is completed, fuel injection is performed before the pressure of the fuel reaches the boosted pressure after the pressure boosting unit starts to be operated. Based on the result, operation starting timing of the pressure boosting unit is adjusted.

Fuel injection amount correction method for pressure boosting fuel injection apparatus

A fuel injector () in an internal combustion engine, wherein an intermediate chamber control valve () operated by the fuel pressure in a common rail () is arranged in a fuel flow passage () connecting a two-position switching type three-way valve () and an intermediate chamber () of a booster piston (). When the fuel pressure in the common rail () is in a high pressure side fuel region, the booster piston () is operated by this intermediate chamber control valve (), while when the fuel pressure in the common rail () is in a low pressure side fuel region, the operation of the booster piston () is stopped by this intermediate chamber control valve ().

A fuel injection system () with reduced pressure pulsations in the fuel discharge paths from the injectors is disclosed. A high-pressure fuel accumulated in a common rail is injected by a plurality of the injectors. Each injector includes a high-pressure chamber for accumulating the fuel, a back pressure chamber into which the high-pressure fuel is introduced from the high-pressure chamber and a nozzle body arranged in the high pressure chamber. Each injector closes the fuel injection port by pushing down the nozzle body under the pressure of the high-pressure fuel introduced into the back pressure chamber. The fuel injection port is opened, on the other hand, by discharging the high-pressure fuel from the back pressure chamber through the fuel discharge path of each injector. A variable-area orifice () is arranged in the discharge path () downstream of the confluence at which all the fuel discharge paths from the injectors are merged with each other. The higher the fuel pressure in the discharge paths, the larger the open area of the variable-area orifice. Thus, a pressure pulsation in the fuel discharge paths from the injectors is reduced.

In controlling power supply time, a variation in the fuel injection quantity caused by a variation in the fuel injection rate at the in-cylinder pressure of the engine (detected or estimated value in the running state of the internal combustion engine) relative to the fuel injection rate at a reference in-cylinder pressure (under the condition of an injector characteristic measuring benchmark test), and in addition, a variation in the fuel injection start time is corrected. In the calculation of the variation in the fuel injection quantity, a fuel injection rate changing behavior model in which changing behavior of the fuel injection rate is modeled as a trapezoid is used to calculate the areas of &#x394;qand &#x394;q. The variation in the fuel injection start time &#x394;&#x3c4;d is calculated based on the rail pressure and the variation in the in-cylinder pressure. In this way, there is provided a technology for controlling the fuel injection quantity that changes with a change in the in-cylinder pressure with improved accuracy.

Fuel injection control apparatus for internal combustion engine

In a fuel system of an internal combustion engine, a fuel pressure sensor is disposed on a high pressure fuel pipe connecting common rail and a fuel injection valve. An electronic control unit (ECU) of the engine calculates the magnitude P of the fuel pressure fluctuation from the fuel pressure detected by the pressure sensor when a pilot fuel injection is executed. The ECU calculates the actual amount Qpl of the pilot fuel injection from the magnitude P and pressure Pc in the high pressure fuel pipe based on the relationship between Qpl and P, Pc determined beforehand by experiment. The ECU further corrects the fuel injection period of the fuel injection valve in such a manner that the difference dQpli between the actual amount Qpl and a target amount Qplt of pilot fuel injection becomes within an allowable range. Thus, the fuel injection amount of the fuel injection valve always agrees with the target fuel injection amount even if a fuel injection characteristics have changed after long period of operating the engine.

Fuel injection control device

A common rail fuel injection apparatus includes a piston that increases the injection pressure, and a chamber that controls the position of the piston so as to control the injection pressure. An input constriction that sets an amount of flow of the fuel that enters the control chamber, and an output constriction that sets an amount of flow of the fuel that exits from the chamber are formed. The input constriction is connected to a common rail by a valve. By opening and closing the valve, the injection pressure of the fuel injected from an injector is changed. Therefore, the injection pressure of fuel injected from the injector can be changed as requested without a need to process high precision component parts.

Common rail fuel injection apparatus and control method thereof

Injectors are connected to a common rail via respective dispensing conduits A mixture of a liquid fuel fed from a liquid fuel tank and an additional fluid fed from an additional fluid tank is formed, and is fed to the common rail The additional fluid contained in the mixture is turned to its supercritical state, and the mixture is injected from the injectors to the engine. The inlets of the dispensing conduits are positioned, with respect to the common rail to open out into a liquid fuel layer which will be formed in the common rail when a separation of the mixture occurs.
