They are reducing pollution by, increasing engine efficiency allowing for engine displacement to be reduced with the same amount of power. Manufacturers are using forced induction (turboes,superchargers) more on smaller displacement engines, to maintain horsepower and increase fuel economy( less fuel burnt means less emissions). Diesel engines are using DEF (diesel exhaust fluid) to reduce NOx. Also diesels come with DPF (diesel particulate filter) an exhaust filter to remove diesel soot from the exhaust. Variable turbes are used to make the diesesl more efficient thru out the rpm range. More hybrids and electric cars are being produced to lessen the amount of uel being burned.
