影響汽車尾氣排放的因素及解決措施

中文摘要
汽車尾氣排放已經(jīng)嚴重威脅了人類生活的環(huán)境，為了防止汽車尾氣放排放日益污染嚴重，因此我決定從此方面入手，對現(xiàn)在汽車尾氣的 進行調(diào)查整合并對此進行研究。隨著人們的生活水平的提高，汽車數(shù)量越來越多，汽車尾氣排放也急劇增加，這成為環(huán)境影響的一個重要的因素。汽車尾氣中的碳氫化合物和氮氧化合物在陽關(guān)作用下發(fā)生化學反應，生成臭氧，它和大氣中的其他成分結(jié)合就形成光化學物，對健康的危害極為嚴重。目前我國汽車尾氣處理技術(shù)能使用為電控燃油供給系統(tǒng)（EFI）：它利用各種傳感器檢測發(fā)動機各種狀態(tài)，經(jīng)微處理器的判斷、計算，使發(fā)動機在不同工況下均能獲得合適的空燃比的混合氣。在任何情況下都能獲得精確的空燃比；混合氣的各缸分配均勻性好；汽車的加速性能
好；充氣率高；良好的起動性能和減速減油或斷油，使汽車尾氣對環(huán)境污染減輕。

Abstract
Vehicle exhaust emission has been a serious threat to human living environment, in order to prevent the discharge of automobile tail gas discharge pullution is serious,so I decided to start noe，on automobile exhaust were investigated and studied the integartion. As people’s living standard rise, the number of cars is increasing，vehicle exhaust emissions have increased dramarically，the environmental impact is an important factor. The automobile tail gas inhydrocarbons and nitrogen oxides in the sun under the effect of chemical reaction，the generated ozone，which in the atmosphere and the other components of photochemistry，the health hazard is very serious，At present our country automobile tail gas treatment technology can be used for the electronic control fuel system (EFI)：it uses a variety of sensors to detect engine state，the microprocessor judgment，calculation，so that the engine in different working condition can be obtained by proper air-fuel ratio of the mixture gas. In any case，can obtain the accurate air fuel ratio；mixed gas distribution uniformity of each cylinder；the car’s acceleration performance is good；the chargeing efficiency is high；a good starting performance and the deceleration and oil or oil，so that the automobile exhaust on the environment pollution loss.
