气体燃烧超能提供有限范围电 carsThis 一种替代方法是大众生态了模型，它返回 CO2 性能的电动汽车，因为它由压缩天然气 (CNG)。 而不是一个草率的转换，占用了大部分的行李空间，当大众工程师被规划 Ups NSF 平台他们确信双气罐可以安装在车没有减小大小的引导。一个大的圆柱形坦克装有启动地板下，另一个是后排座位下。大众也已经设法挤出 10 公升油箱油箱旁边。打开生态 Ups 燃料皮瓣和有气体填料和常规燃料加注。汽车燃料压力计，也是双功能，在启动时，在切换到指示 CNG 水平之前的几秒钟油箱里显示的金额。所有其他更改都不见了，里面的三缸发动机。具体注射器 CNG 和一个新的引擎管理系统一套，已从 10 提高压缩比。5:1 到 11。5:1，火花塞提供更高的点火电压和活塞与凸轮轴配置文件已被修改。新材料被用于阀门和阀门指南，而且在不同可变气门正时设置的。生态上还可以检测高 （98%甲烷） 气体和现售，助长德国 911 CNG 站的低 （85%甲烷） 气体之间的区别。它显示在燃烧中的真正的环境差异 CNG 相比汽油催化转换器变为。燃烧天然气释放 25%左右较少 CO2 说，大众汽车，以及作为远少包括一氧化碳和碳氢化合物，而微粒不在所有发出的污染物。所有的这意味着在变频器内部使用的材料是不同。翻译从德国展厅价格，生态成本 2500 年左右超过标准的汽油车，这是大概可以理解考虑超强气罐和什么将一个相对较低卷车所需的工程修改的额外费用。 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.
