影響汽油發動機排放的最主要因素是混合氣的空燃比， 理論上一公斤燃料完全燃燒時需要14.7公斤的空氣。這種空氣和燃料的比例稱為化學當量比。空燃比小于化學當量比時供給濃混合氣，此時發動機發出的功率大，但燃燒不完全，生成的CO、HC多；當混合氣略大于化學當量比時，燃燒效率最高，燃油消耗量低，但生成的NOx也最多；供給稀混合氣時，燃燒速度變慢，燃燒不穩定，使得HC增多。在電控汽油噴射系統中采用閉環控制的方式，將空燃比控制在化學當量比附近，并在排氣系統中消聲器前安裝一個三元催化轉化器，對發動機進行后處理，是當前減少汽車排氣污染物的最有效方法。在化學當量比附近，轉化器的凈化效率最高。

CC386 is a general-purpose 32-bit C compiler. It is not an optimizing compiler but given that the code generation is fairly good. There are two versions one is for MSDOS/DPMI and one is for Win32. The Win32 version has a full-blown IDE capable of editing, building, and debugging windows programs included with it. However at this time debugging support for MSDOS is rudimentary at best and there is no IDE for DOS. the newest version, support windows.
