大衆承認汽車二氧化碳排放數值也存在問題

Volkswagen’s woes deepened on Tuesday as the German carmaker admitted it had found problems involving carbon dioxide emissions on 800,000 cars — including some with petrol engines — at a possible cost to the company of about 2bn.

大衆(Volkswagen)週二陷入更多麻煩。這家德國汽車製造商承認，發現80萬輛汽車（包括一些汽油發動機汽車）存在與二氧化碳排放有關的問題，這可能會令該公司付出大約20億歐元的代價。

The problems are a different issue from the scandal VW has been facing since September over the excess Nitrogen Oxide emissions from up to 11m vehicles worldwide fitted with software designed to cheat at emissions tests. Carbon Dioxide emissions depend on a vehicle’s fuel consumption, not its emissions-control systems.

這個問題和9月以來大衆所面臨的醜聞不同。這場醜聞的問題在於，全球至多1100萬輛裝有特殊軟件的汽車氮氧化物排放過多，這些軟件的目的是在尾氣排放測試中矇混過關。二氧化碳的排放量取決於汽車的燃油消耗，而不是其排放控制系統。

However, the company said it had discovered the issue during “comprehensive investigations” it had promised following the emergence of the NOx cheating scandal.

不過，該公司表示，其已在氮氧化物排放作弊醜聞爆發後承諾開展的“全面調查”期間發現這個問題。

The statement gave no information about where the affected vehicles were sold, the brands affected or whether they involved diesel or petrol engines.

該聲明並未披露受影響的汽車銷往何方、受影響品牌有哪些、以及受影響的是柴油還是汽油發動機。

“During the course of internal investigations, unexplained inconsistencies were found when determining Type Approval CO2 levels,” a company statement said. “Based on present knowledge around 800,000 vehicles from the Volkswagen Group are affected.”

該公司的一份聲明表示：“內部調查期間，發現在型式認可測試中確定二氧化碳排放水平時，存在無法解釋的數據不一致現象。據目前所知，約80萬輛產自大衆集團的汽車受這一問題影響。”

However, the company told the Financial Times that the vehicles affected were “mostly diesels,” although for the first time petrol engines were involved in the scandal. The vehicles’ emissions were understated and fuel economy overstated.

不過，該公司向英國《金融時報》表示，儘管汽油發動機首次捲入這一醜聞，但受影響的汽車“主要是柴油發動機”。相關汽車的排放量被低估，燃油經濟性被高估。

The vehicles all have 1.4 litre engines — they are mostly VW Polos and Golfs but also some Audi, Seat and Skoda cars.

所有汽車都裝有1.4升的發動機，它們主要是大衆的Polo和高爾夫(Golf)，不過也包括部分奧迪(Audi)、西雅特(Seat)和斯柯達(Skoda)汽車。
