An activated carbon material derived, for example, by carbonizing and activating a non-lignocellulosic carbon precursor has a structural order ratio less than or equal to 0.08, and a nitrogen content greater than 0.2 wt. %. The activated carbon material can also have a volumetric capacitance greater than or equal to 70 F / cm3, an area-specific resistance less than or equal to 0.1 ohm-cm2 and / or a specific surface area greater than 300 m2 / g, and is suitable to form improved carbon-based electrodes for use in high energy density devices.

The invention relates to a double-layer split-flow burning system of a direct-injection diesel engine and belongs to the fields of engine mix gas formation and combustion. The double-layer split-flow burning system of the direct-injection diesel engine is characterized in that a combustion chamber is divided into an upper layer and a lower layer; the diameter of the upper layer part of the combustion chamber is greater than that of the lower layer part of the combustion chamber; the space between the top surface of a piston and the bottom surface of a cylinder cover is reduced; and a collision platform is arranged at the joint of the upper layer and the lower layer; an oil beam squirted by a multi-hole oil injector impacts the collision platform, one part of the oil beam is rebounded so that the secondary atomization is realized, one part of the oil beam flows to the upper layer and the lower layer of the combustion chamber along a guide surface, and the accumulation of spraying at the landing point and nearby is reduced through guiding and splitting; and the diffusion speed is rapid, the air rolling suction quantity is increased, thus the relative uniform mixed gas is rapidly formed, the combustion is fast and complete, and the economy and emission behavior of the diesel engine are improved. Compared with the double-layer split-flow burning system and the original machine burning system under a declared working condition, the oil consumption rate is reduced by 3%, and the discharge capacity of soot is reduced by 50%.
