氩气是一种用于稀释火花点火发动机进气的惰性气体，以减少氮氧化物，提高发动机的性能。在本工作中使用的研究引擎里卡多E6可变压缩。一个特殊的试验台已经设计和建造，允许气体进入发动机的进气空气高达15%的进气。该系统可以允许预定量的惰性气体、氧气和氮气进入。研究的变量包括发动机转速、氩气与进气比和空燃比。结果包括燃烧压力、温度、已燃质量分数、放热率、制动功率、热效率、充气效率、排气温度、制动比油耗以及CO、CO2、NO和O2的排放。结果表明，在汽油机进气中加入氩气，可以有效地减少氮氧化物的排放，提高发动机的制动功率和热效率。利用数学程序计算了氩气对混合物性质的影响，并计算了氩气对混合物性质的影响。
The Argon inert gas is used to dilute the intake air of a spark ignition engine to decrease nitrogen oxides and improve the performance of the engine. A research engine Ricardo E6 with variable compression was used in the present work. A special test rig has been designed and built to admit the gas to the intake air of the engine for up to 15% of the intake air. The system could admit the inert gas, oxygen and nitrogen gases at preset amounts. The variables studied included the engine speed, Argon to inlet air ratio, and air to fuel ratio. The results presented here included the combustion pressure, temperature, burned mass fraction, heat release rate, brake power, thermal efficiency, volumetric efficiency, exhaust temperature, brake specific fuel consumption and emissions of CO, CO2, NO and O2. It was found that the addition of Argon gas to the intake air of the gasoline engine causes the nitrogen oxide to reduce effectively and also it caused the brake power and thermal efficiency of the engine to increase. Mathematical program has been used to obtain the mixture properties and the heat release when the Argon gas is used.
