汽油机的点火提前角是个很重要的参数,它不仅影响发动机的动力性、经济性、排放、启动、怠速稳定性,而且直接影响发动机的可靠性及使用寿命。正确控制和调整点火提前角,对提高产品质量是十分重要的。一九八五年,我们在解决 EQ6100汽油机活塞烧顶问题的过程中,对各种点火提前角的调整方法以及点火角对发动机性能的影响进行了摸索和试验,现加以总结。为叙述系 Gasoline ignition timing is a very important parameter, which not only affects the engine power, economy, emissions, start, idle stability, but also directly affect the reliability and service life of the engine. Correct control and adjust the ignition advance angle, to improve product quality is very important. In 1985, during the process of solving the burning problem of EQ6100 gasoline engine pistons, we made various investigations and tests on the ways of adjusting ignition timing and the influence of ignition angles on engine performance.
