摘要：
Two-stroke, fuel injected internal combustion engines for unmanned aircraft and associated systems and methods are disclosed herein. Engines configured in accordance with embodiments of the disclosure can include, for example, (a) an electronic fuel injection system configured to provide a desired low fuel rate by injecting fuel every nth compression cycle rather than every cycle (so-called "skip-cycle" operation), (b) one or more pressure sensors configured to measure fluctuations in peak crankcase pressure and use such fluctuations to control fuel injection delivery, and (c) a multi-cylinder configuration having a common crankcase with a fuel injection arrangement configured to mitigate or eliminate problems with mixed redistribution.
摘要（中）：
本文公开了用于无人驾驶飞行器的二冲程燃料喷射内燃机及相关系统和方法。 根据本公开的实施例构造的发动机可以包括例如（a）电子燃料喷射系统，该电子燃料喷射系统被配置为通过每第n个压缩循环而不是每个周期喷射燃料来提供期望的低燃料速率（所谓的“跳过循环 “操作”），（b）一个或多个压力传感器，被配置为测量曲轴箱顶部压力的波动并使用这种波动来控制燃料喷射输送;以及（c）具有共同的曲轴箱的多气缸构造，燃料喷射装置配置成 减轻或消除混合再分配的问题。
