氣體燃燒超能提供有限範圍電 carsThis 一種替代方法是大眾生態了模型，它返回 CO2 性能的電動汽車，因為它由壓縮天然氣 (CNG)。 而不是一個草率的轉換，佔用了大部分的行李空間，當大眾工程師被規劃 Ups NSF 平臺他們確信雙氣罐可以安裝在車沒有減小大小的引導。一個大的圓柱形坦克裝有啟動地板下，另一個是後排座位下。大眾也已經設法擠出 10 公升油箱油箱旁邊。打開生態 Ups 燃料皮瓣和有氣體填料和常規燃料加注。汽車燃料壓力計，也是雙功能，在啟動時，在切換到指示 CNG 水準之前的幾秒鐘油箱裡顯示的金額。所有其他更改都不見了，裡面的三缸發動機。具體注射器 CNG 和一個新的引擎管理系統一套，已從 10 提高壓縮比。5:1 到 11。5:1，火花塞提供更高的點火電壓和活塞與凸輪軸設定檔已被修改。新材料被用於閥門和閥門指南，而且在不同可變氣門正時設置的。生態上還可以檢測高 （98%甲烷） 氣體和現售，助長德國 911 CNG 站的低 （85%甲烷） 氣體之間的區別。它顯示在燃燒中的真正的環境差異 CNG 相比汽油催化轉換器變為。燃燒天然氣釋放 25%左右較少 CO2 說，大眾汽車，以及作為遠少包括一氧化碳和碳氫化合物，而微粒不在所有發出的污染物。所有的這意味著在變頻器內部使用的材料是不同。翻譯從德國展廳價格，生態成本 2500 年左右超過標準的汽油車，這是大概可以理解考慮超強氣罐和什麼將一個相對較低卷車所需的工程修改的額外費用。 Gas-burning supermini could provide a real alternative to limited-range electric carsThis is Volkswagens Eco Up model, which returns the CO2 performance of an electric vehicle because it is powered by compressed natural gas (CNG). Rather than being a hasty conversion, which takes up most of the luggage space, when VW engineers were planning the Ups NSF platform they made sure that twin gas tanks could be fitted in the car without reducing the size of the boot. One of the large, cylindrical tanks is fitted under the boot floor, the other is under the rear seat. VW has also managed to squeeze a 10-litre petrol tank alongside the gas tanks. Open the Eco Ups fuel flap and theres both the gas filler and the conventional fuel filler. The cars fuel gauge is also dual-function, showing the amount in the petrol tank for a few seconds on start-up, before switching to indicating CNG levels. All the other changes are out of sight, inside the three-cylinder engine. As well as a set of specific injectors for the CNG and a new engine management system, the compression ratio has been raised from 10. 5:1 to 11. 5:1, the spark plugs supply a higher ignition voltage and the camshaft profiles and pistons have been modified. New materials were used for the valves and valve guides, and the variable valve-timing settings are different. The Eco Up can also detect the difference between High (98 per cent methane) gas and Low (85 per cent methane) gas that is on sale at Germanys 911 CNG-fuelling stations. Its the changes to the catalytic convertor that show the real environmental differences in burning CNG compared to petrol. Burning CNG releases around 25 per cent less CO2 says VW, as well as far less in the way of pollutants including carbon monoxide and hydrocarbons, while fine particulates are not emitted at all. All of which means the materials used inside the convertor are different. Translated from the German showroom prices, the Eco Up costs around 2500 more than the standard petrol car, which is probably understandable considering the extra costs of the super-strong gas tanks and the engineering modifications needed for what will be a relatively low-volume car.
