3缸内直喷式汽油机的工作原理缸内直喷式汽油机的工作原理如图9所示。(1)气缸内涡流的运动。在进气过程中,通过直立式进气管,在气缸吸力的作用下,产生强大的下降气流,使充气效率得到提高。又在顶面弯曲活塞的作用下,形成比传统汽油机更强大的滚动涡流。这个滚动涡流,将压缩后期喷射出的旋转油雾,带到燃烧室中央的火花塞附近,然后及时点火燃烧。
3 cylinder direct injection gasoline engine working principle Cylinder direct injection gasoline engine working principle shown in Figure 9. (1) the vortex movement in the cylinder. In the intake process, through the vertical intake pipe, the cylinder suction under the action of a strong decline in airflow, so that the inflatable efficiency is improved. Under the action of the top curved piston, it forms a more powerful rolling vortex than traditional gasoline engines. This rolling vortex, will be compressed after the spray of rotating oil mist, to the center of the combustion chamber near the spark plug, and then promptly ignited combustion.
