Sentence examples for emission advantages from inspiring English sources

We conclude that CO2 emission advantages of diesel cars can be close to absent if gauged against modernized petrol-driven engines.

Use of hydrogen in spark ignition engines as supplementary fuel can be preferred due to improved combustion characteristics and emission advantages.

Aggregated with the combustion CO2 emission advantages of solely 3.5 g·km−1 (Figure 4), recent diesel cars in Europe theoretically exhibit a climate advantage of 4 g CO2 equivalents km−1.

While the former chapter discussed whether there is a fundamental efficiency, i.e. GHG emission advantages of diesel cars versus petrol-fuelled cars, on-road CO2 emissions of new passenger cars are analyzed subsequently.

New diesel passenger cars in Europe therefore lost most of their CO2 emission advantage over gasoline cars (Figure 4).

In its fourth assessment report, IPCC[3] announced an outstanding 25% well-to-wheel CO2 emission advantage of a diesel car compared to its petrol equivalent.

This effect reduces the CO2 emission advantage of diesel cars suggested by favourable fuel efficiency measured in volumetric terms (l/100 km or miles gal−1).

Since 2009, diesel car CO2 emission advantage over petrol cars in Europe became marginal and went down to 1.5% in 2010 (Figure 4).

The emission advantage for EVs is not obvious while the charging power is supplied by coal-fired power plants primarily [7].

We however believe that the mere extra well-to-tank CO2 emissions caused by the strong demand for this type of fuel most likely overcompensates this minor aggregate emission advantage of modern diesel cars in real-life situations.

However, prior to Euro 5 standards mandatory since 2009, the European Commission allowed diesel cars to emit 25 mg PM km−1 emission according to Euro 4. This corresponds to 19.5 g of CO2 emissions, which is largely exceeding the maximum pre-2007 CO2 emission advantage new diesel cars possessed over petrol cars (Figure 4).
