The cetane number measures the ignition delay of a fuel. It is measured in terms of the volume % of cetane in a mixture of cetane (C16H34) and methyl naphthalene (C₁1H₁0). A certain brand of gasoline was burned and analyzed to have the following flue gas composition: 12.54% CO₂, 2.21% CO, 3.09% D2, and 82.16% N₂. Assume the fuel contains only cetane (p = 0.7751) and methyl naphthalene (p= 1.025). What is the cetane number of the fuel?

Problem 1
The cetane number measures the ignition delay of a fuel. It is measured in terms of the volume % of
cetane in a mixture of cetane (C₁6H34) and methyl naphthalene (C₁1H₁0). A certain brand of gasoline
was burned and analyzed to have the following flue gas composition: 12.54% CO2, 2.21% CO, 3.09%
O₂, and 82.16% N₂. Assume the fuel contains only cetane (p = 0.7751) and methyl naphthalene (p =
1.025). What is the cetane number of the fuel?
