    • A multi-cylinder opposed piston engine (100) can include one or more sensors, such as oxygen or nox sensors (132, 134, 136, 138, 142), for each cylinder (103) of the multi-cylinder opposed piston engine (100). The sensors (132, 134, 136, 138, 142) are in communication with an engine control unit (102) that can receive measurements and other data from the sensors. In one example, each cylinder (103) includes one or more sensors (132, 134) located adjacent to exhaust ports (144) of each individual cylinder (103). In another example, each cylinder (103) includes one or more sensors (136, 138) located in an exhaust passageway (146) of each individual cylinder (103). In some examples, the multi-cylinder opposed piston engine (100) can include multiple crankshafts (114, 116). For example, the multi-cylinder opposed piston engine (100) can include two crankshafts (114, 116), where each crankshaft (114, 116) engages, either directly or indirectly, one of two opposed pistons (104, 106) of a cylinder (103). In one example, each crankshaft (114, 116) includes one or more sensors, such as a torque sensor (120, 122), a speed sensor (124, 126), or a noise, vibration, and harshness (NVH) sensor (150, 152).
    • 多缸对置活塞发动机(100)可以包括用于每个气缸(103)的一个或多个传感器,例如氧气或氧气传感器(132,134,136,138,142) 多缸对置活塞式发动机(100)。 传感器(132,134,136,138,142)与可接收来自传感器的测量数据和其他数据的发动机控制单元(102)通信。 在一个示例中,每个汽缸(103)包括位于每个单独汽缸(103)的排气口(144)附近的一个或多个传感器(132,134)。 在另一个示例中,每个气缸(103)包括位于每个单独气缸(103)的排气通道(146)中的一个或多个传感器(136,138)。 在一些示例中,多缸对置活塞发动机(100)可以包括多个曲轴(114,116)。 例如,多缸对置活塞发动机(100)可以包括两个曲轴(114,116),其中每个曲轴(114,116)直接或间接地接合两个相对的活塞(104,106)中的一个, 汽缸(103)。 在一个示例中,每个曲轴(114,116)包括一个或多个传感器,诸如转矩传感器(120,122),速度传感器(124,126)或噪声,振动和粗糙度(NVH)传感器( 150,152)。
