    Abstract: A method and apparatus for reducing oxides of nitrogen in the exhaust of an internal combustion engine. The apparatus includes a pressurizing unit for providing compressed air to a pressure swing adsorption unit. The pressure swing adsorption removes nitrogen from the air to produce nitrogen-reduced air, which is then supplied to the engine. The pressurizing unit may be a compressor, a turbocharger, or a supercharger. The engine may utilize exhaust gas recirculation and fuel injection with air assist.

    Abstract: A low emission power generating apparatus which comprises a modified two-stroke diesel engine component and a modified turbocharger component which has a relatively low aspect ratio. The diesel engine component is a modification of a conventional two-stroke diesel engine design and includes a modified connecting rod assembly which causes a modified piston to accelerate rapidly within the combustion chamber and an exhaust valve cam of unique design that has a cam profile which results in a later than-normal exhaust valve opening and an earlier-than-normal valve closing so that the time during which the exhaust valve remains open is shorter than normal, thereby causing a substantially greater volume of residual gases to remain in the combustion chamber following the scavenge stroke. This increase in the volume of the residual exhaust gases within the chamber leads to an increase in compression temperature and effectively increases the compression ratio and consequently the compression pressure. Because of the heat absorption capacity of these residual exhaust gases, the exhaust gases remaining in the chamber following the scavenge stroke tend to absorb combustion heat and thereby effectively reduce the peak combustion temperature. This reduction in peak combustion temperature advantageously results in the lower than normal formation of nitrogen oxide (NOx) and, therefore, allows advancement of the injection timing, while still maintaining the NOx emissions coming from the engine lower than those legislatively mandated. Advantageously, the advance in injection timing, which increases NOx emissions, by definition has the effect of also reducing particulate matter emissions. Thus, by increasing the volume of residual exhaust gases within the cylinder, substantial particulate matter emission reductions can be achieved, while at the same time maintaining NOx emissions well below mandated limits. The modified turbocharger component provides an additional charge of oxygen-rich air into the combustion chamber which effectively increases the compression pressure, which, in turn, leads to an earlier start of combustion because of the combustible mixture reaching its auto-ignition temperature at an earlier point in the cycle. This phenomenon leads to more thorough combustion of the fuel and also generally leads to higher exhaust temperatures. Higher exhaust temperatures, in turn, lead to a greater oxidation rate of the soluble organic fraction thus lowering the level of emission from the engine of undesirable particulate matter.

    Abstract translation: 一种低排放发电装置，其包括改进的二冲程柴油发动机部件和具有相对低的纵横比的改进的涡轮增压器部件。 柴油发动机部件是常规二冲程柴油发动机设计的改进，并且包括具有独特设计的排气门凸轮，其具有凸轮轮廓，其导致晚于正常的排气阀打开和比正常情况更早的阀 关闭，使得排气阀保持打开的时间比正常时间短，从而导致在清除行程之后燃烧室中剩余气体基本上更大的体积。 室内剩余废气体积的增加导致压缩温度升高，并且有效地增加了压缩比并因此提高了压缩压力。 由于这些残留废气的吸热能力，在清除行程之后残留在室中的废气倾向于吸收燃烧热量，从而有效地降低峰值燃烧温度。 峰值燃烧温度的这种降低有利地导致低于氮氧化物（NO x）的正常生产，并且因此允许提前喷射正时，同时仍保持来自发动机的NOx排放低于立法规定的NOx排放。
