1. You might say, "Well, gee, why don't we just power our cars with hydrogen placed on an internal combustion chamber." 你可能会说：“好吧，哎呀，为什么我们不把氢气放在汽车内部的燃烧室，来驱动我们的汽车呢。”
2. The combustion of larger molecules, which have multiple carbon-carbon bonds, involves a more complex series of reactions. 具有多重碳-碳键的大分子的燃烧涉及到一系列更复杂的反应。
3. In his application, Selden described a machine with a gasoline-driven, combustion-type engine that sat in front of the driver. 在他的申请中，塞尔登描述了一种有汽油驱动的燃烧式发动机的机器，它就在司机的前面。
4. In 2006 he converted a powered hang-glider, removing its small combustion engine and replacing it with a battery and an electric motor. 2006年，他转向了动力滑翔机，同时把小型内燃机拆了下来，用电池和电动机来替代。
5. These reactions increase the probability of incomplete combustion and are more likely to release uncombusted and photochemically active hydrocarbon compounds into the atmosphere. 这些反应增加了不完全燃烧的可能性，更有可能释放未燃尽和光化学活性碳氢化合物到大气中。
