(with and without catalyzed diesel particulate filters [DPF]). The researchers reported that fuel economy for the hybrid bus was 54% higher than the two regular diesel buses. In another study, tw 一项研究由Battelle (5) 被测试的放射使用一支功率计为一辆柴油杂种电公共汽车和二辆规则柴油公共汽车 ...
Since the late 2000s, DPFs (Diesel Particulate Filters) have been introduced as a new catalytic converter in the diesel world. There was a problem with diesel engines generally being dirtier burn than gas engines. We are sure that many of you have been driving and have seen that black smoke...
2.B.细节理解题.根据文章第二段Much of the slowdown is the result of diesel(柴油) cars, which were supported by governments because they use less fuel and thus produce less carbon dioxide than petrol cars它们得到了政府的支持,因为它们使用的燃料较少,因此产生的二氧化碳也比汽油车少...

response functions for childhood asthma (0–18 years) from international systematic meta-analyses and a smaller Australian cross-sectional study were applied to comparative elevations in fine particulate matter (PM2.5) and nitrogen dioxide (NO2) concentrations between the EPA reference monitor (used ...
Air pollution is a major global health concern, especially due to exposure to fine particulate matter (PM2.5) [1]. This exposure has been linked to cardiovascular diseases, as PM2.5is a complex mixture of toxic constituents that can negatively affect cardiac function and promote cardiac infarcts ...
