Nitro has more oxygen in it Nitromethane has oxygen in it. The oxygen in nitro displaces the fuel in nitro. To make up for that, more volume is needed to bring in enough fuel. This is necessary for combustion with the oxygen in the nitromethane as well as the oxygen in the air. Additionally, nitro methanol mixtures burn hotter than straight methanol. As a result, the mixture is run rich for more cooling. The increased enrichment lowers the air/fuel ratio number even more. The combustion of oxygen in nitromethane methanol mixture with the fuel is complex. As combustion progresses, fuel dissociation occurs in multiple steps. Instantaneous intermediate chemicals are formed as combustion goes from preliminary ignition to the final, flame spewing fire out the exhaust. |
硝基甲烷本身有氧。硝基中的氧取代硝基中的燃料。为了弥补这一点,需要更多的体积来提供足够的燃料。这对于烧掉硝基甲烷中的氧以及空气中的氧是必要的。此外,硝基甲醇混合燃料比单纯甲醇燃烧温度更高。其结果是,混合油燃烧更富油,以实现更多的冷却。增加的浓缩会降低空/燃比。 富油多冷却,是调出来的,为了得到更高转速,调啊调啊调出来的。结果,就是在最高转时比少硝基的状态更冷却了。 结论是,发动机的最佳状态(最高转)和冷却效果通过调机,最终一看,哦,冷却效果更好了。所以大家就都这么说了。 |
