摘要： A hydraulically-actuated fuel injector includes an injector body having a nozzle chamber that opens to a nozzle outlet and a plunger bore, and further has a prime spill port and an idle stability port that open to the plunger bore. A hydraulic means for pressurizing fuel in the nozzle chamber includes a plunger mounted to reciprocate in the plunger bore between a retracted position and an advanced position. A portion of the plunger bore and plunger define a fuel pressurization chamber. A needle valve member is mounted to reciprocate in the nozzle chamber between an open position in which the nozzle outlet is open and a closed position in which the nozzle outlet is closed. A portion of the plunger blocks the prime spill port when the plunger is in its retracted position. A different portion of the plunger blocks the idle stability port when the plunger is in its retracted position. The prime spill port opens to the fuel pressurization chamber over part of the plunger stroke between its retracted position and its advanced position. The idle stability port opens to the fuel pressurization chamber over a different part of the plunger stroke between its retracted position and its advanced position. The prime spill port has a relatively unrestricted flow area, whereas the idle stability port has a relatively restricted flow area about equal to that of the nozzle outlet.

摘要： Existing poppet valves have a tendency to rebound or bounce during operation. This rebound or bounce adversely affects engine governability, high pressure injector fuel flow, noise and idle stability. The present invention reduces or nearly eliminates poppet valve (52) rebound or bounce. The apparatus (161) for compensating for the rebound of bounce overcomes the problem of variable injection. For example, as the poppet valve (52) rebounds the weight (174) strikes the bottom or contacting surface (168) preventing the poppet valve (52) from moving toward the first position (156). Thus, the variation in the injection of fuel is prevented or eliminated. Additionally, with the variation in the injection of fuel eliminated, the adverse affects of the bounce or rebound enables better engine governability, high pressure injector fuel flow and idle stability with reduced noise.
摘要翻译：现有的提升阀在运行中具有反弹或反弹的倾向。这种反弹或反弹对发动机的可控性，高压喷射器燃料流量，噪声和怠速稳定性产生不利影响。本发明减少或几乎消除了提升阀（52）反弹或反弹。用于补偿反弹反弹的装置（161）克服了可变喷射的问题。例如，当提升阀52重弹时碰撞底部或接触表面168阻止提升阀52向第一位置移动。因此，防止或消除燃料喷射的变化。此外，随着消除燃料喷射的变化，反弹或反弹的不利影响可实现更好的发动机调节能力，高压喷油器燃油流量和空闲稳定性，降低噪音。

摘要： A thermal storage unit having at least one conduit around which a cast is made is provided. The thermal storage unit uses conventional piping or tubing to create conduits that economically maximize the surface area of flow in contact with the thermal mass by proving multiple passes for the fluid through the cast. This enables the thermal storage unit to economically provide heat storage as well as effective heat delivery and pressure containment for a fluid flowing through the conduit.

摘要： A fuel injector includes an injector body that defines a low pressure space, a trapped volume and a fuel pressurization chamber in fluid communication with a nozzle outlet. A needle valve member is positioned in the injector body and moveable between an inject position in which the fuel pressurization chamber is opened to the nozzle outlet, and a closed position in which the nozzle outlet is blocked to the fuel pressurization chamber. The needle valve member includes a lifting hydraulic surface exposed to fluid pressure in the fuel pressurization chamber, and a closing hydraulic surface exposed to fluid pressure in the trapped volume. At least one of the injector body and the needle valve member define a pressure decay passage extending between the trapped volume and the low pressure space.

摘要： A method of fuel injection comprises the initial step of providing a fuel injector with a solenoid actuated control valve mounted in an actuation fluid cavity. The valve is biased to a first position but movable to a second position against the bias when the solenoid is energized. When in its first position, the actuation fluid cavity is opened to a high pressure actuation fluid inlet, but opened to a low pressure fluid actuation fluid drain when in its second position. In the next step, the desired amount of fuel to be injected is determined. An actuation duration for the solenoid corresponding to the desired amount of fuel is calculated. Then, it is determined whether the actuation duration corresponds to a cavitation zone of operation for the control valve. Next an injection event is initiated by moving the valve to open the actuation fluid cavity to the high pressure actuation fluid inlet. After the actuation duration, the control valve is moved toward the position that opens the low pressure actuation fluid drain. If it is determined that the injector was operating within the cavitation zone of operation, then the movement rate of the control valve while closing is slowed while it is moving to close the high pressure actuation fluid inlet. This slowing of the valve's closure sufficiently alters conditions within the injector that pressure does not drop to cavitation levels.
摘要翻译：燃料喷射的方法包括向燃料喷射器提供安装在致动流体腔中的电磁致动控制阀的初始步骤。当螺线管通电时，阀被偏置到第一位置，但是可以抵抗偏压而移动到第二位置。当处于其第一位置时，致动流体腔被打开到高压致动流体入口，但在处于其第二位置时被打开到低压流体致动流体排放口。在下一步骤中，确定要注入的燃料量。计算对应于期望量的燃料的螺线管的致动持续时间。然后，确定致动持续时间是否对应于控制阀的操作空化区。接下来，通过移动阀门将致动流体腔打开到高压致动流体入口来启动喷射事件。在致动持续时间之后，控制阀向打开低压致动流体排放的位置移动。如果确定喷射器在气蚀区域内操作，则关闭时的控制阀的移动速度在移动以关闭高压致动流体入口时减慢。阀门闭合的这种减慢充分地改变了喷射器内的压力不会下降到空化水平的条件。

摘要： Past methods for starting an engine have included increasing the amount of fuel to support combustion creating an excess of unburned fuel in the exhaust causing white smoke. Such past methods for starting an engine additionally required additional components, such as heater, and required an excessive draw on the battery to provide extensive glow plug operation and extensive cranking. The present method of starting an engine reduces and essentially eliminates white smoke, reduces the need for extensive glow plug operation and reduces the need for extensive cranking. The method of starting an engine includes the steps of: positioning an intake valve in a closed position; positioning an exhaust valve in a closed position; rotating a piston to a top dead center position; rotating the piston from the top dead center position toward a bottom dead center position; and injecting a fuel into the cylinder.
摘要翻译：用于起动发动机的过去的方法包括增加燃料的量以支持燃烧，从而在排气中产生过量的未燃烧燃料，引起白烟。用于起动发动机的这种过去的方法另外需要额外的部件，例如加热器，并且需要对电池进行过度的抽吸以提供广泛的电热塞操作和大量的起动。目前的起动发动机的方法减少并基本上消除了白烟，减少了对广泛的电热塞操作的需要，并且减少了对大量起动的需要。起动发动机的方法包括以下步骤：将进气门定位在关闭位置; 将排气阀定位在关闭位置; 将活塞旋转到上止点位置; 将活塞从上死点位置向下死点位置旋转; 并将燃料喷射到气缸中。
