The engine would use at least 25% less fuel and, he claims, its emissions of carbon dioxide and nitrogen oxide would be cut by three-quarters because of its unique ignition properties.

利奥尔博士还表示，由于其独特的点火特性，新型引擎（发动机）的二氧化碳和一氧化氮气体排放量将会减少3/4。

The result also indicates that ignition temperature of coal blend is mainly decided by the properties of easily ignited coal when coals blended with great different ignition properties.

计算结果进一步证明，由两种着火特性差别较大煤种组成的混煤，其着火温度主要取决于易着火煤的着火特性。
