摘要

火花点火直接喷射(SIDI)发动机可能会带来重大的改进,因为他们的潜在的燃料消耗的减少。然而,为了在满足严格的排放标准的同时保持高效率,这款发动机还需要进一步的发展,包括先进的废气处理和与其运行特性兼容的低硫燃料。这些发动机热效率的其他改进是由于废气的成分更接近空气,温度更低(这减少了热量损失),过量空气的诱导减少了泵送损失。在最后一种情况下,重要的是要提到Ostrikov等人,2018[1]开发了一种用于清洁拖拉机柴油机润滑系统的工艺流程和冲洗成分冲洗油。此外,Buratsev等人,2018[2]在研究天然气湍流燃烧时观察到,一个反应堆燃烧室的热强度增加,导致其体积减小,导致启动试剂完全转化,并降低炭黑的形成,那么这一评论应该适用于发动机的燃烧室。

Comparative Study of Estimatives and Experimental Published Results of Spark Ignition Engine Performance using Different Fuels.
Spark ignition direct injection (SIDI) engines may bring a major improvement in SI engines because of their potential reduction in fuel consumption. However, for compliance with stringent emissions standards while performing at highefficiency levels, this engine requires further development, including advanced exhaust treatment and low sulfur fuel compatible with its operating characteristics.Other improvements to thermal efficiency for these engines result from the exhaust gases having a composition much closer to that of air and a lower temperature (which reduces heat loss) and the induction of excess air reduces pumping losses.In this last case, it is important to mention that Ostrikov et al., 2018 [1] developed a technological process and a flushing composition flushing oil for cleaning lubricating system of tractor diesel engines. Also, Buratsev et al, 2018 [2] working with turbulent combustion of natural gas have observed that the increasinge in the calorific intensity of the combustion chamber of one reactor as a result of a decrease in its volume leads to full conversion of the starting reagents and to lower carbon-black formation, then this remark ought to be applied to the combustion chambre of the engines.
