VW公佈了一些有關將來eco-friendy engines的新技術。一個是新的混合燃燒技術CCS，類似柴油引擎，CCS將油氣混合的更完美，排放出更少的NO。但是CCS需要新的汽油來達到這項技術。Volkswagen has revealed details about some of its upcoming technologies planned for its cars, with most of the spotlight centered on more eco-friendly engines. First up is a new Combined Combustion System (CCS) engine technology. Similar to diesel units, CCS mixes the fuel and air ‘homogeneously’ inside the engine, which in effect removes any trace of soot and reduces polluting nitrogen oxides. CCS also requires a synthetic fuel for optimal results.
新的汽油"SynFuel"是從天然氣中提煉出來，目前有好幾個汽車公司在發展。 第二項新技術："汽油壓縮點火系統，GCI system"，能夠兼具汽油引擎的乾淨排放與柴油引擎的燃燒效率。GCI系統在車子起步及急加速的時候才點火，而在低負荷下改用壓縮點火。 這兩項新的技術要到2015年才會用在量產車上面。
The new fuel, called SynFuel, is derived from natural gas and is currently under development by several carmakers. Another engine technology is Gasoline Compression Ignition(GCI) system, which promises to be as clean as petrol motors but as efficient as diesels. GCI works by using spark plugs during start-up and hard acceleration, but relying on sparkless compression ignition, like a diesel, during low load situations, such as cruising on a highway. Both the CCS and GCI is planned to be introduced into production cars by 2015, 4Car reports.
Merc：儘管柴油科技已經突飛猛進，但是問題是他還是需要消耗柴油。在美國市場，加柴油比汽油來的難找許多。因此，Merc提出一項新的發展概念"DiesOtto"。 Diesel technology has improved by leaps and bounds, but the trouble is, it still runs on diesel. In the American market, at least, finding a diesel pump is still a pain compared to filling up with conventional gasoline. Mercedes-Benz says it's found the solution with a new developmental powertrain concept it calls DiesOtto.
We first reported on the project a couple of years ago, but the German automaker now has a functioning prototype. Rather than actually running on diesel, the DiesOtto engine is said to incorporate the benefits of a diesel engine, but runs on regular old unleaded. The prototype is a 1.8-liter four-cylinder engine that uses direct injection, variable compression, turbocharging and something MB calls "controlled auto ignition" to deliver 238 horsepower and 295 lb-ft of torque, with a claimed return of "less than 6 liters per 100 kilometers", which translates to 39.2 mpg. Those numbers, Benz claims, are not based on a small car (like the C-Class or smaller) but on a large sedan (like the S-Class). They may not be entirely revolutionary figures, but any way you look at it, they're damn impressive.
Merc並沒有說明這項科技何時會用在量產車上，只說這是相當適合新能源過渡時期的技術。 Mercedes hasn't put a timeline on producing and marketing a powertrain based on the DiesOtto prototype, but says it's a "feasible proposition in the midterm". We certainly hope so.
