This paper analyzes the forming principle, effecting factors and controlling measures of poisonous gas of exhaust emission from petrol engine for vehicle fully and accurately. after the comparison on the emission control measures, it is clear that there is a trade - off relation between emission control and power, torque, fuel consumption of engine. " efi + catalytic converter " is a integration measure of in - engine and out - engine, which is a mainstream technology of emission control for petrol engine for vehicle
本文通過大量的文獻閱讀，翔實的分析了車用汽油機排氣中有害氣體成分的產生機理、影響生成的主要因素、治理排氣污染物的主要技術措施，指出這些措施與發動機的其他性能（如動力性、經濟性等）的一種折中關系，只有「電控噴射+排氣催化轉化」是一種機內與機外相結合的措施，是控制車用汽油機排放的主流技術。Emission producing mechanism of diesel emission and the impacts on human and environment caused by these substances are discussed firstly, drawing a conclusion that particulate and nox are the key of diesel emission control and developing a basic knowledge on emission regulations and testing technologies. a few after - treatment technologies of diesel engine are summarized and a simple evaluation system is created
論文首先分析了柴油機有害排放物的生成機理以及對人體與環境的影響，指出pm和no _ x是柴油機的主要排放物，也是柴油機排放控制的難點與重點，總結了當前國內外柴油機排放標準和測試技術，綜合分析了幾種可能在近期內實用化的后處理技術，並提出了一套簡單的評價體系。Through adjusting the controlling fuel injection - - regulations of the two injection timings and proportions, an adequate air and fuel charge stratification was produced - we call it quasi - homogenous mixture and the lean burn was successfully realized in a product 4 - valve s. i. engine whose structures are n ' t changed at all. investigations show that twice electronic fuel injection can make the lean limit ( a / f ) increase by 1. 5 - 2 units ; the fuel consumption and exhaust emissions are improved remarkably, in partial load, compared with the product 4 - valve s. i
研究結果表明：兩次噴油可拓展發動機稀燃極限1 . 5 - 2個空燃比單位，最高達23 . 5 ；發動機燃油消耗同原電噴發動機相比可降低19 . 1 % ；整個空燃比范圍內，經過優化的兩次噴油稀燃的最低油耗較單次噴油稀燃下降6 . 5 %左右，各種排放物機內生成量均有大幅度下降。Phytases catalyze the hydrolysis of phytic acid or phytate ( myo - inositol hexakisphosphate ) to inositol and inorganic phosphate. their roles in eliminating anti - nutritional effects of phytate in plant fodder or foods, in increasing the efficiencies of protein and various microelement utilizations in the animal body and the animal productivities, in reducing the amount of phosphorus in animal excretions and thus reducing environmental pollutions, etc, have been the research focuses domestically and internationally
植酸酶是一類能催化植酸及植酸鹽水解成肌醇和無機磷酸鹽的酶，它具有解除植物性飼料（或食品）中植酸的抗營養作用、提高機體對蛋白質及多種微量元素的利用率、促進生長發育、提高動物生產性能、減少糞便中磷的排放量、降低磷對環境的污染等多種功能，因而受到國內外的廣泛關注。Fine particulate matter and other emissions from older diesel - powered trucks and buses contribute to air pollution in beijing and throughout china and pose serious public health concerns. environmental impacts of diesel exhaust emissions include its contribution to ozone formation and acid rain
美國環境保護署的新聞簡報說，從年代較久的柴油機動車中排放出的微粒物質和廢氣是造成中國空氣污染和由此產生的種種健康問題的部分原因。Their emissions are especially damaging, too ? partly because the nitrogen oxides from jet - engine exhausts help create ozone, a potent greenhouse gas, and partly because the pretty trails that aircraft leave behind them help make the clouds that can intensify the greenhouse effect
他們製造出的排放物質對大氣層的破壞也尤為嚴重? ?這一方面是由於噴氣式發動機工作產生的氮氧化物會促使臭氧的形成，而臭氧是一種強溫室氣體；另一方面是飛機掠過后留下的漂亮尾跡會有助於雲的形成，從而加強溫室效應。分享友人
