[amp_mcq option1=”Lowering sulfur content in fuel” option2=”Increasing sulfur content in fuel” option3=”Lowering carbon content in fuel” option4=”increasing carbon content in fuel” correct=”option1″]<\/p>\n
The correct answer is: A. Lowering sulfur content in fuel.<\/p>\n
The Euro II standard is an emission standard for vehicles that was introduced in 1996. It limits the amount of sulfur that can be present in fuel, which helps to reduce air pollution. Sulfur in fuel can react with oxygen in the air to form sulfur dioxide, which is a major contributor to acid rain.<\/p>\n
The Euro II standard also limits the amount of nitrogen oxides (NOx) and particulate matter (PM) that can be emitted by vehicles. NOx and PM are both pollutants that can cause respiratory problems and other health issues.<\/p>\n
The Euro II standard was followed by the Euro III, Euro IV, Euro V, and Euro VI standards, which have progressively stricter emission limits. The Euro VI standard is the most recent standard and was introduced in 2014.<\/p>\n
The Euro standards are an important part of the effort to reduce air pollution from vehicles. By limiting the amount of pollutants that can be emitted, the Euro standards help to improve air quality and protect public health.<\/p>\n
