  8. Cetane number - Wikipedia

    en.wikipedia.org/wiki/Cetane_number

    The cetane number of a fuel is defined by finding a blend of cetane and isocetane with the same ignition delay. Cetane has a cetane number defined to be 100, while isocetane's measured cetane number is 15, replacing the former reference fuel alpha-methylnaphthalene, which was assigned a cetane number of 0.

  9. Vehicle emissions control - Wikipedia

    en.wikipedia.org/wiki/Vehicle_emissions_control

    By the 1974 model year, the United States emission standards had tightened such that the de-tuning techniques used to meet them were seriously reducing engine efficiency and thus increasing fuel usage. The new emission standards for 1975 model year, as well as the increase in fuel usage, forced the invention of the catalytic converter for after ...
