    • Operation of unthrottled internal combustion engines is improved by providing the combustion chambers with an electrically heated glow plug having a catalyst surface layer on the ignition element. The catalyst is heated to and maintained at a temperature high enough to be effective for vaporization of fuel drops and ignition of vaporized fuel by controlled electrical heating. In operation of the engine air is compressed in a combustion chamber and at least a portion of the fuel is injected during the latter portion of the compression stroke and the injected fuel ignited by contact of fuel with the hot catalytic surface of the glow plug resulting in a combustion pressure wave in the immediate vicinity of top dead center.

    • Methanol is passed over a catalyst at an elevated temperature and pressure to produce a fuel gas containing a high proportion of methane in a one-step catalytic conversion process. Removal of water and carbon dioxide from the fuel gas produces a synthetic natural gas. For example, methanol with water is passed over a precious metal catalyst such as ruthenium on alumina at a temperature in the range of about 350.degree. C. to 500.degree. C. and a pressure in the range of about 800 to 2500 psig to produce a gaseous mixture comprising methane, carbon dioxide, minor amounts of hydrogen and essentially no carbon monoxide. Upon condensing the water vapor and scrubbing out the carbon dioxide, synthetic natural gas is obtained having a methane content above 90% by volume.
    • 甲醇在升高的温度和压力下通过催化剂,以在一步催化转化过程中产生含有高比例甲烷的燃料气体。 从燃料气中去除水和二氧化碳产生合成天然气。 例如,在约350℃至500℃的温度和约800至2500psig范围内的压力下,将含有水的甲醇在氧化铝上通过贵金属催化剂如钌,从而产生 包含甲烷,二氧化碳,少量氢气和基本上不含一氧化碳的气态混合物。 在冷凝水蒸气并洗涤二氧化碳时,获得甲烷含量高于90体积%的合成天然气。

    • An internal combustion piston engine utilizing a catalyst to promote combustion and not requiring spark ignition. A catalyst member is provided within the engine cylinder. Air is supplied to the cylinder and is compressed by a piston. At or near the point of maximum compression, fuel is contacted with the catalyst, preferably from the side of the catalyst opposite the piston. The fuel and air mix to initiate combustion and the air-fuel mixture passes through the catalyst member, completing the combustion. The operation can result in relatively complete combustion of the fuel at a relatively low temperature of about 1800.degree. to 3300.degree. or 3500.degree. F. so that little or no undesirable components are present in the engine exhaust, especially the exhaust may have a low content of nitrogen oxides.
    • 利用催化剂促进燃烧并且不需要火花点火的内燃活塞发动机。 催化剂构件设置在发动机气缸内。 空气被供给到气缸并被活塞压缩。 在最大压缩点处或附近,燃料与催化剂接触,优选地从催化剂与活塞相对的一侧接触。 燃料和空气混合以开始燃烧,空气 - 燃料混合物通过催化剂构件,完成燃烧。 该操作可以在约1800°至3300°或3500°F的较低温度下燃料相对完全燃烧,因此在发动机排气中几乎不存在或不存在不期望的组分,特别是排气可能具有低含量 的氮氧化物。
