← ScienceWhich consequence results when biofuel combustion preheating fails?
A)Ignition delay and incomplete combustion✓
B)Increased NOx formation accelerates reactions
C)Homogeneous mixture formation within exhaust
D)Reduced carbon monoxide emission rates
💡 Explanation
Incomplete combustion occurs because insufficient preheating means the fuel does not reach its required Fuel Vaporisation energy so Arrhenius equation parameters dictate that high activation energies reduce reaction. The biofuel will not reach the temperature to react fully, rather than decreasing NOx.
