Sentence examples for diesels over time from inspiring English sources

Olsson et al. (2011) note that the original studies estimated diesel exposure "using expert case-by-case assessment" by local experts and took into account the increasing use of diesels over time, which was considered a strength of the method.

Based on comparable data as shown in Figure 4, Ajanovic[14] argues that 'the largest part of saving over time was brought about by overall efficiency improvements for both gasoline and diesel cars.
