摘要： A fuel injection valve of a diesel engine, comprising a valve body including a concave conical surface in the tip portion of the valve body, and fuel injection holes extending from the concave surface to the outside of the valve body, and a needle valve movable in the valve body and including a cylindrical shaft portion, a first conical surface adjacent to the shaft portion and having a conical angle smaller than that of the concave surface, the lower edge of the first conical surface defining a contact line separably contacting with the concave surface, a second conical surface adjacent to the first surface and having a conical angle substantially equal to that of the concave surface, a third conical surface adjacent to the second surface and having a conical angle greater than that of the concave surface. In case of a smaller lift amount of the needle valve, the fuel flow speed flowing into the fuel injection hole is fast and the atomized fuel injection divergence angle from the injection hole is great, thereby producing active producing mixing of the fuel with the air and enhancing the ignition feature, while in case of a greater lift amount, the fuel flow speed is slow and the atomized fuel injection divergence angle from the injection hole is small, thereby increasing the fuel flow reach and producing an active mixing of the fuel with the air by virtue of the kinetic energy of the atomized fuel flow.

摘要： A fuel injection nozzle of the present invention has an accumulating chamber in a body in which high pressure fuel fed from the fuel injection pump is stored using a non-return valve. A needle valve is arranged in the body to inject the fuel in the accumulating chamber. A nozzle needle of the needle valve and a valve member are arranged coaxially and in series with each other. Those end portions of the nozzle needle and valve member which are adjacent to each other are slidably and liquid-sealingly fitted together to define a damping chamber between the valve member and the nozzle needle. Further, a damping plunger is coaxially fitted into the valve member. A passage which connects the damping chamber with the side of the fuel injection pump is coaxially formed in the damping plunger and has a reduced area.

摘要： A fuel injection nozzle of this invention includes a nozzle housing which defines therein a fuel sump chamber, stepped cylinder bore and fuel passage connected at one end to the sump chamber and at the other end to a smaller diameter bore section of a stepped bore. A stepped plunger is fitted into the stepped cylinder bore to define a pump chamber communicating with the fuel passage and a main fuel chamber into which the main fuel is supplied from a fuel injection pump. An auxiliary fuel is supplied from a feed pump through the fuel passage into the sump chamber and pump chamber. A nozzle needle is located within the nozzle housing and is responsive to a fuel pressure within the sump chamber to cause it to be lifted to permit an injection hole to be opened. The nozzle needle is urged under a predetermined force of a pressure spring in a direction in which the injection hole is blocked. The urging force of the pressure spring is set to be greater than the pressure of the auxiliary fuel supplied from the feed pump and smaller than the pressure of the main fuel supplied from the fuel injection pump. The main fuel chamber, when the plunger is moved a predetermined distance responsive to the fuel pressure within the main fuel chamber, is permitted to be connected to the fuel passage.

摘要： According to the present invention, a fuel injection apparatus includes a casing having a control pressure chamber for storing fuel supplied from fuel passage, a needle valve to which fuel stored in the control pressure chamber applies pressure in the valve closing direction, a valve device for interrupting communication between the fuel passage and the control pressure chamber to seal fuel in said control pressure chamber, and volume changing device for expanding volume of the control pressure chamber after fuel is sealed in the control pressure chamber by the valve device. According to the above fuel injection device, pressure in the control pressure chamber is reduced while the fuel is stored therein by the volume changing device, the nozzle needle is lifted, and injection is started. For this reason, it is not necessary to supply surplus fuel in addition to the injection fuel during the fuel injection. In this way, the fuel supply pump is made smaller in size, and efficiency for use of supplied fuel can be improved. Further, since high-pressure fuel is not discharged from the fuel injection apparatus, pulsation within the common rail can be suppressed, and fuel injection can be stabilized.

摘要： To provide a fuel injection pump which can sufficiently and stably supply fuel to a fuel pressurization chamber during a fuel intake stroke, a plunger chamber, a spill port and a spill passage are mutually communicable, while a reflux passage, an intake gallery, an intake passage, an intake port and the plunger chamber are mutually communicable. A reflux passage communicates with a damping chamber through a communication passage. The spill passage and the reflux passage communicate with each other, and when a spill valve opens, high-pressure fuel within the plunger chamber spills from the spill valve and into the intake gallery through the reflux passage, causing pulsation having a pressure level difference to the spill fuel. When the pulsation wave passes through the damping chamber, as the level difference in the pulsation wave is reduced, a sufficient quantity of fuel can stably be supplied from the intake gallery to the plunger chamber.

摘要： In a high pressure fuel injection system, fuel is pumped up from a fuel tank by a low pressure pump and further pressurized by a high pressure pump. Pressurized fuel is accumulated in a common rail connected to injectors which inject fuel into an engine. A high pressure regulator is connected to the common rail to mechanically relieve excessive fuel pressure in the common rail or to electronically reduce the fuel pressure when required. An electronic control unit controls operation of the high pressure pump, the high pressure regulator and the injectors according to engine operating conditions which are fed to the unit from various sensors. The fuel pressure in the common rail is decreased by operation of the high pressure pump and the high pressure regulator either rapidly or gradually according to engine operating conditions. Vapor, including fuel and air, accumulated in the common rail under high ambient temperature is purged out quickly before the engine is stared by driving only the low pressure pump under command from the electronic control unit. The system is also provided with a "limp-home" function under which a car is driven back home even when some portions of the system fail or malfunction.

摘要： A fuel injection control apparatus for use in an engine wherein fuel injection is controlled in accordance with the conditions of the engines operation. This apparatus is provided with a fuel quantity control unit of the distribution type which measures and discharges an amount of fuel in response to detection signals which represent the conditions of the engines operation, and with a plurality of unit injectors for distributing and supplying fuel to their respective engine cylinders, said fuel being set and measured by the fuel quantity control unit. Each of said unit injectors comprises a compression plunger driven by a cam system which is rotated by a rotation shaft of said engine, a compression pump chamber whose fuel pressure is set by the operation of said compression plunger, an injection plunger driven by the fuel pressure in the compression pump chamber, an injection pump chamber which is filled with fuel whose pressure has been set by the operation of said injection plunger and whose amount has been adjusted by the fuel amount adjuster means, and a timing plunger whose position is set by the amount of fuel adjusted, wherein the fuel pressure in the compression pump chamber caused when the compression plunger is driven causes the timing plunger to move to a specified position and then acts on the injection plunger to raise the pressure in the injection pump chamber, thereby enabling the quantity-adjusted fuel in the injection pump chamber to be injected.
