1) 自然吸氣 Natural-Aspirated
2) 渦輪增壓 Turbo
3) 機械增壓 Supercharge

just read other forum and wanna know their different....

自然吸氣,NA的引擎是利用汽缸內活塞下降的負壓來吸入混合氣,其原理 和我們肺部呼吸的原理一樣。由於是靠氣壓吸氣,因此被給入 汽缸的壓力也大約只有一個大氣壓力(atm),而且引擎的出力受氣壓影響,氣壓高,引擎出力就高;氣壓低,出力就低。雖然如此 ,但Turbo車在引擎轉速不足(前輪先於後輪失卻循跡性, 結果前輪的弧度比後輪大。感覺上車頭好像被推向外,如果轉向不足時再踏油門,會令重心移向車尾),未有足夠的壓力推動渦輪時,其表現可能比NA車更差,因此買車用來代步的人,很多也會選擇NA車

渦輪增壓,是以汽車排出廢氣的壓力推動渦輪,渦輪的轉動再帶動同 軸的空氣壓縮葉片,藉此將壓縮的混合氣吸入汽缸。由於渦輪增壓不受大氣壓 力影響,所以即使在低氣壓的情況下,Turbo引擎也能維持高出力,其實"渦輪增壓" 的技術本身就是為解決飛機在高空(低氣壓)的地方飛行時,引擎出力降低 的情況而開發的。由於渦輪增壓是利用高溫,高壓的廢氣來推動渦輪葉片,所產生出來的壓力比 NA(自然吸氣)車還要大,當Turbo全力運作時,引擎的出力可提升30至40%。

機械增壓,的轉子葉片是直接以皮帶經由引擎曲軸驅動,也因此,引擎只要一發動就有增壓效果,它也因此而較消耗部分的引擎動力...

你當我是浮誇吧 
誇張只因我很怕
似木頭似石頭的話
得到注意嗎
其實怕被忘記 
至放大來演吧
很不安 怎去優雅
世上還讚頌沉默嗎 
不夠爆炸
怎麼有話題 讓我誇 做大娛樂家

Rotary 係由 Mazda, Ford 等等推出市場, 馬力同食油都比同 size 0既 Piston 引擎多, 所以電油公司當年非常歡迎, 但係一個正常 Rotary 引擎係自然吸氣, 可另加 Turbo 同 SuperCharger...

SuperCharger 曾經係勝於 Turbo, 因為大0既 Turbo 要到差唔多 4000rpm 至會有反應, 同埋反應太突然, 但係 SuperCharger 由 < 1000rpm 就開始慢慢加馬力, 但最高馬力通常都可以話係 Turbo 勝出, 但係今時今日0既 Turbo, 有0佐 Ball-Bearing, 3000rpm 以下已差唔多 max boost, 馬力更勝於 SuperCharger, (仲有好多其它好處, 好處多過 SC 好多) 所以已經冇乜人仲會鍾情於 SC 了!!

Yeah., sound supercharge suit me wor..., i dun like "反應太突然", that not comfortable when driving..all my back push by the seat when accelerate.....

haha... that's the fun of the turbo when the boost comes on and you're sucked back into ur seat... :P (just kidding...) these days the turbo (boost) comes on much earlier (with ball bearing turbos) and with a aftermarket computer, many things can be tuned, and with different setups for eg. electronic boost control, you can have the power delivery as smooth as you like, or tuned at full power (as how it should be... :D)

I don't think many people will go with supercharger these days, as it's quite inefficient compared to turbos, unless you got a second hand supercharger engine etc..

由考獲車牌直到現在,我都用過好幾部車,但講到最滿意,都係對上一部:掃把佬WRX,Turbo加�琱[四驅,真係無得頂,到而家仲好懷念背脊黐椅背o既快感。
