    • With reference to FIG. 1, the present invention provides an internal combustion engine (10) comprisinga variable volume combustion chamber (13); an air intake system (18,20,21) for delivering charge air to the combustion chamber (13); an exhaust system (17) for relaying combusted gas from the combustion chamber (13) to atmosphere; and a fuel injection system (19, 21, 22, 23, 24, 25, 26) for delivering fuel into the charge air for combustion therewith in the combustion chamber (13). The fuel injection system (19,21,22,23,24,25,26) comprises a fuel injector (19) which functions as a positive displacement pump and dispenses an amount of fuel which is fixed for each and every operation of the injector (19); and a controller (23) which controls the operation of the fuel injector (19). In response to an increasing engine speed and/or load the controller (23) increases in amount the fuel delivered per engine cycle by increasing in number the occasions the fuel injector (19) is operated per engine cycle. In response to a decreasing engine speed and/or load the controller (23) reduces in amount the fuel delivered per engine cycle by reducing in number the occasions the fuel injector (19) is operated per engine cycle.
    • 参考图1。 如图1所示,本发明提供一种包括可变容积燃烧室(13)的内燃机(10)。 用于将增压空气输送到所述燃烧室(13)的进气系统(18,20,21)。 用于将燃烧气体从燃烧室(13)转移到大气的排气系统(17); 以及用于在燃烧室(13)中将燃料输送到用于燃烧的增压空气中的燃料喷射系统(19,21,22,23,24,25,26)。 燃料喷射系统(19,21,22,23,24,25,26)包括燃料喷射器(19),燃料喷射器(19)用作正排量泵并且分配一定量的燃料,该燃料量对于喷射器的每次操作都是固定的 (19); 以及控制燃料喷射器(19)的操作的控制器(23)。 响应于增加的发动机速度和/或负载,控制器(23)通过在每个发动机循环中操作燃料喷射器(19)的情况下增加数量来增加每个发动机循环的燃料量。 响应于发动机转速和/或负载的降低,控制器(23)通过减少每个发动机循环中燃料喷射器(19)的操作次数来减少发动机循环中输送的燃料的量。

    • A bioresorbable endoluminal prosthesis for placement in a body lumen having a stent substrate of a first metallic material that has a lower electrical potential than a standard reference electrode. The stent substrate is coated with a biodegradable polymer having a second metallic material dispersed therein, wherein the second metallic material has a higher electrical potential than the standard reference electrode. After implantation of the stent within the body lumen, the second metallic material is present in the polymeric coating in a sufficient concentration to cause galvanic corrosion of the first metallic material such that over time the stent substrate is bioresorbed.
    • 一种生物可再吸收的腔内假体,用于放置在具有比标准参考电极具有更低电位的第一金属材料的支架基底的体腔内。 所述支架基底涂覆有分散在其中的第二金属材料的可生物降解的聚合物,其中所述第二金属材料具有比所述标准参比电极更高的电位。 在将支架植入体腔内之后,第二金属材料以足够的浓度存在于聚合物涂层中,以引起第一金属材料的电化学腐蚀,使得随着时间的推移,支架基底被生物吸收。
