This expansion takes energy from the air, resulting in temperature reduction, a process known as adiabatic cooling. 此膨胀吸收了空气中的能量,导致空气温度下降,这个过程称为绝热冷却。
Using the electronic control system and the catalyzing system of lean combustion engines developed by ourselves studies on reducing NOx emissions in different air fuel ratios in reduction process with the absorption reduction catalyzing method are done. 运用自行开发设计的稀燃发动机电控系统和催化系统,对稀燃汽油机运用吸附还原催化法在不同的还原过程空燃比条件下降低NOx的排放进行了研究。
