    • A compression ignition gasoline engine uses low-cetane number fuel, such as gasoline. The engine includes a combustion control device having an injector directly injecting fuel into a combustion chamber, intake and exhaust valves, and a variable valve device changing a valve timing, in which the compression ignition gasoline engine includes: at least two intake valves and two exhaust valves; a spark plug positioned at the center portion of the combustion chamber; and an injector positioned adjacent to the spark plug toward the center portion of the combustion chamber, in which the exhaust valve is a symmetric valve lift in which the lift and the opening section of the tow exhaust valves are the same in low lift, and the intake valve is an asymmetric valve lift in which the lift and the opening of the two intake valves are different in the low lift.
    • 压燃点火汽油机采用低十六烷值燃料,如汽油。 发动机包括燃料控制装置,其具有将燃料直接喷射到燃烧室中的喷射器,进气和排气阀以及改变气门正时的可变气门装置,其中压燃点火汽油机包括:至少两个进气门和两个排气 阀门 位于所述燃烧室的中心部分的火花塞; 以及朝向燃烧室的中心部分位于火花塞附近的喷射器,其中排气门是对称的气门升程,其中,在低升程中,牵引排气门的升程和开启部分相同, 进气阀是不对称的气门升程,其中两个进气门的升程和开度在低升程中是不同的。

    • The present invention provides an electrode made of carbon nanotubes or carbon nanofibers and a process for preparing the same. The electrode comprising a current collector, sulfur or metal nanoparticles as a binder, and carbon nanotubes or carbon nanofibers is characterized in that the sulfur or metal nanoparticles are bonded, deposited, or fused on the surfaces of the carbon nanotubes or carbon nanofibers so that the carbon nanotubes or carbon nanofibers are bonded to each other and also bonded to the current collector. The electrode prepared according to the present invention exhibits low internal resistance, strong durability and low equivalent series resistance, and therefore the electrode can be effectively used for secondary batteries, supercapacitors or fuel cells.
    • 本发明提供一种由碳纳米管或碳​​纳米纤维制成的电极及其制备方法。 包含集电体,作为粘合剂的硫或金属纳米颗粒的电极和碳纳米管或碳​​纳米纤维的特征在于,硫或金属纳米颗粒结合,沉积或熔合在碳纳米管或碳​​纳米纤维的表面上,使得 碳纳米管或碳​​纳米纤维彼此键合并且也结合到集电体。 根据本发明制备的电极显示出低内阻,强耐久性和低等效串联电阻,因此电极可以有效地用于二次电池,超级电容器或燃料电池。
