That's a combustion reaction — an exothermic oxidation (a redox) reaction. Gasoline (hydrocarbons) reacts with oxygen to produce CO2 and H2O, releasing heat that is converted to mechanical work. Example (octane):
2 C8H18 + 25 O2 → 16 CO2 + 18 H2O

Incomplete combustion can produce CO and soot instead of only CO2.
