发动机的一些名词解释英文
发动机的一些名词解释英文发动机是现代汽车的核心设备之一，负责产生动力并驱动车辆运行。
了解发动机中的一些常见名词及其英文对应，有助于我们更好地理解和使用汽车。
本文将介绍发动机中的一些关键名词，并提供相应的英文解释。
1. 气缸（Cylinder）汽车发动机通常由多个气缸组成，每个气缸内都有一个活塞。
气缸是发动机燃烧室的一部分，用于容纳和压缩空气和燃料混合物，产生爆炸力来驱动活塞运动。
在发动机规模确定后，气缸的数量是一个关键参数。
2. 活塞（Piston）活塞是位于气缸内的一个圆柱形部件，负责产生往复运动。
活塞通过连接杆与曲轴相连，曲轴将活塞的直线运动转换为旋转运动，从而提供动力给汽车。
3. 曲轴（Crankshaft）曲轴是发动机中一个非常重要的部件，它将活塞的往复运动转换为连续的旋转运动。
曲轴能够将发动机的高速旋转动力输出到传动系统，驱动车辆行驶。
曲轴的工作原理可以视为一个平衡的重锤，可以抵消活塞产生的晃动力。
4. 燃烧室（Combustion chamber）发动机的燃烧室是气缸的一部分，用于容纳空气和燃料混合物的燃烧。
燃烧室的设计直接影响发动机的功率、燃烧效率和排放水平。
5. 点火系统（Ignition system）点火系统用于点燃气缸内的混合物，引起爆炸，从而推动活塞的运动。
点火系统中的重要组件包括点火线圈、火花塞和点火控制单元。
6. 进气歧管（Intake manifold）进气歧管是连接发动机气缸与空气滤清器之间的部件，用于输送空气和燃料混合物到燃烧室。
进气歧管的设计对发动机性能有着重要影响，如进气效率和动力输出。
7. 排气歧管（Exhaust manifold）排气歧管与进气歧管相对应，负责将燃烧产生的废气从燃烧室排出。
排气歧管的设计也会影响发动机效能，如排气效率和噪音水平。
8. 涡轮增压（Turbocharging）涡轮增压是一种提高发动机功率和扭矩输出的技术。
通过安装涡轮增压器，增加进气歧管中的压力，从而提高燃烧效率，实现更高的动力输出。
