在发动机气缸中,燃烧情况决定车辆性能和排放扬。影响燃烧的因素包括燃油的化学性质,燃油与空气混合物的质量(即雾化程度和混合均匀度),空燃比,发动机形状和点火系统特性等。在现代和将来的车辆中,废气再循环的作用也一定要认真考虑。为了解决急需解决的排放物标准而又能维持良好的车辆驱动性,了解以上各因素的作用并使其更完善是很重要的。在目前的工作中,用一般的汽化器单缸发动机(楔形燃烧室)研究多火花电容放电点火系统对基本的发动机运转,排放物,稀混合气失火和废气再循环限量的作用特点。将结果与标准(批量生产的类型)点火系统进行比较。
In the engine cylinder, the combustion conditions determine vehicle performance and emissions. Factors that affect combustion include the chemical nature of the fuel, the mass of the fuel-air mixture (ie degree of atomization and mixing uniformity), air-fuel ratio, engine shape and ignition system characteristics. In modern and future vehicles, the role of exhaust gas recirculation must also be carefully considered. It is important to understand and refine the role of each of these factors in order to address the emission standards that are urgently needed to be addressed while maintaining good vehicle drivers. In the present work, the effect of a spark ignition capacitor discharge ignition system on basic engine operation, emissions, lean gas misfires, and exhaust gas recirculation limits was studied using a typical carburetor single cylinder engine (wedge combustor). Compare the results with a standard (mass produced type) ignition system.
