Civic TypeR 想買一台啊+1

圖片沒啥用啦....
來看看實車啦...不過...要熱車這點...很麻煩的...
油煙一堆...噪音又大...

真扯... Go Kart 上面落這種引擎﹐如果場地不夠大我還真不敢上去
164匹... 這樣下來馬力重量比就是 1... 太恐怖

話說上次朋友一臺 250 就把我們一堆 ICA 跟 MAX 抓假的﹐換成這臺的話
大概每兩圈被套一次

250???是4行程的嗎???還是2行程的??
我要入門的是先以250的二行成為入門款..
164PS那台馬力重量比不到1啦..
那台重量好像是150KG..
另外那台113.5的重量好像是135KG..
如果是使用二行程的250引擎...要弄到60PS是OK的..
車子重量也會下降不少..所以效果不會有很大的差距..
KART如果玩到我這個階段...應該算是白痴或者是神經病等級...

只玩過手排 RX-7 , 打開引擎蓋才發現幾乎是空的 . 排氣是髒了一些, 不過拉引擎轉速就是一個快字. 還沒那種機會接觸燃氣渦輪引擎的車輛 (M-1 / T-80s / MTT Turbine SUPERBIKE http://www.marineturbine.com/motorsports.asp)

關於燃氣渦輪引擎(渦輪軸引擎)的簡介

The bottom line is that turbine power is superior to that of reciprocating engine. So this begs the question:

Why aren't there more turbine engines on the market in non-aviation installations? The main reason is that turbines are expensive. Historically, the only potential buyers were governments, big businesses, and extremely wealthy individuals. For instance, in the 1960's turbines appeared in boats such as the British Pegasus Patrol Boat, the San Francisco Ferry, the U.S. LCAC Hovercraft, and several personal yachts belonging to international royal family members, such as the Aga Khan's Destriero. The TransAtlantic champion Gentry Eagle used turbines as well. Currently, the U.S. Navy uses turbines for main propulsion and power generation on all DDG and FFG frigates and destroyers. The good news, however, is that because MTT has access to many turbine outlets, we are able to install a fully reconditioned, marinized, and tested turbine engine into our product packages for approximately $100.00 to $150.00 per horsepower, which is economically comparable to marine diesel power. If dollar per horsepower per service hour is considered, the turbine engine is actually more cost effective than
reciprocating engines.

Advantages

Wankel engines have several major advantages over reciprocating piston designs, in addition to having higher output for similar displacement and physical size. Wankel engines are considerably simpler and contain far fewer moving parts. For instance, because valving is accomplished by simple ports cut into the walls of the rotor housing, they have no valves or complex valve trains; in addition, since the rotor is geared directly to the output shaft, there is no need for connecting rods, a conventional crankshaft, crankshaft balance weights, etc. The elimination of these parts not only makes a Wankel engine much lighter (typically half that of a conventional engine of equivalent power), but it also completely eliminates the reciprocating mass of a piston engine with its internal strain and inherent vibration due to repeated acceleration and deceleration, producing not only a smoother flow of power but also the ability to produce more power by running at higher rpm.

In addition to the enhanced reliability by virtue of the elimination of this reciprocating strain on internal parts, the engine is constructed with an iron rotor within a housing made of aluminum, which has greater thermal expansion. This ensures that even a severely overheated Wankel engine cannot seize, as would likely occur in an overheated piston engine. This is a substantial safety benefit in aircraft use since no valves can burn out.

A further advantage of the Wankel engine for use in aircraft is the fact that a Wankel engine can have a smaller frontal area than a piston engine of equivalent power.

The simplicity of design and smaller size of the Wankel engine also allows for savings in construction costs, compared to piston engines of comparable power output.

Due to a 50% longer stroke duration compared to a four stroke engine, there is more time to complete the combustion. This leads to greater suitability for direct injection.

There is no empty stroke.

Needs no enrichment for full load (wot).

As another advantage, the shape of the Wankel combustion chamber and the turbulence induced by the moving rotor prevent localized hot spots from forming, thereby allowing the use of fuel of very low octane number or very low ignition power requirement without preignition or detonation, a particular advantage for hydrogen cars. Mazda has recently placed a hydrogen-burning rotary engine in one version of its RX-8 sports car and Mazda 5.

Disadvantages
Compared to piston engines, the time available for fuel to be injected into a Wankel engine is significantly shorter, due to the way the three chambers rotate. Mixture cannot be pre-stored (no intake valve). This means that to get good performance out of a Wankel engine fuel injection technologies are more complicated than for regular four-stroke engines. This difference in intake times also causes Wankel engines to be more susceptible to pressure loss at low rpm compared to regular piston engines.

In terms of fuel economy, Wankel engines are generally less efficient than four stroke piston engines, and although there is some evidence that the NSU Wankel Spider disproves this, most experts would agree that the high (27 mpg) rating of that car was due largely to its incredibly light weight. Problems also occur with exhaust gases at a peripheral port exhaust, where the prevalence of hydrocarbon can be higher than from the exhausts of regular piston engines.

Modern Wankels such as the Renesis found in the RX8 burn a small quantity of oil by design; it is metered into the combustion chamber in order to preserve the rotor tips. Owners must periodically add small amounts of oil, slightly increasing running costs.

四行程的
聲音很低沉﹐直線全油門過的時候﹐維修區的地面都會震
別說白痴啦﹐不過神經病瘋子倒是真的

希望有機會去觀賞你的愛車

4行程...SA250嗎??
那顆好像是38PS...出力還不錯..

我正在做引擎..不過...58.15的活塞要650..
一次還要兩顆..有點貴..
行程是54M/M..化油器是28M/M的..
出力...有40PS吧..
轉速設定是15000RPM以下(表頭只有15000RPM的.. )..
目前正在翻工廠不要的材料來加工成引擎..這樣最省錢..

亂入一下...這台蠻強的
