  • fuel : n. 1. 燃料，柴炭。 ★指燃料種類時為可數名詞。2. 刺激物。vt. ,vi. （〈英國〉 -ll-）（給…）加[供給]燃料，（給船等）上煤，（給…）加油。-er 使用特製混合燃料的賽車。
  • mixture : n. 1. 混合，混雜；混合狀態。2. 混合物；混合體；（內燃機等用的）混合氣；【醫學】混合劑，藥水；混合煙草〈又叫 smoking mixture〉。3. 【織】麻花織品；優缺點均有的人。
  1. The bump height and secondary wall - impingement distance were discovered to play an important role in producing a secondary space jet, reducing the quantity of fuel stuck on the wall and forming lean mixture, and their suitable values being 1. 0 - 1. 5mm and 0 - 2. 0mm respectively

    發現bump高度及二次撞壁距離對撞壁油束形成二次空間射流、減少壁面燃油堆積以及形成稀混合氣有重要作用，且發現bump的高度和二次撞壁距離分別為1 . 0 1 . 5mm和0 2 . 0mm比較合適。
  2. 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。
  3. Engine, the fuel consumption decreases by about 19. 1 %. on the other hand, the fuel consumption of quasi - homogenous mixture lean combustion decreases by about 6. 5 % compared with homogenous lean mixture combustion. three - ways catalyst ( twc ) + optimizing afr technology is used to remove nox emissions in oxygen containing exhaust gas

    本研究運用三效催化器+空燃比優化控制技術，利用三效催化器能一定程度降低nox排放的特點，控制發動機在優化空燃比下工作，將稀燃後排氣中剩餘不多的nox進一步催化。
  4. Lean burn concepts such as the homogenous a / f mixture gasoline lean burn engine or the direct injected gasoline engine may point the way of future automobile developments. a new point of view that the mixture preparation processes can been controlled by controlling fuel injection in multi - port fuel injection engine, in contrast to the traditionally point of view that the mixture formation is only controlled by induction flow

    突破進氣道噴射發動機不依靠噴射生成混合氣，只能通過組織缸內空氣運動來形成這一傳統觀點，本文提出了在進氣道噴射發動機上通過可控噴油形成可控的缸內準均質稀混合氣，進而實現快速準均質稀薄燃燒的新概念。
