The answer to this question would be be combustion & expansion hope this helps :)

Answer 2

The release of CO2, H2O, and CO occurs during the exhaust step of the four-stroke engine cycle.

Step-by-step explanation:

The release of CO2, H2O, and CO occurs during the exhaust step of the four-stroke engine cycle.

In this step, the burned mixture of fuel and air is expelled from the engine through the exhaust valve. Along with the exhaust gases, which include CO2, H2O, CO, and nitrogen, other byproducts and pollutants are also released.

The exhaust gases are then directed out of the vehicle through the exhaust system, usually through a catalytic converter that helps reduce harmful emissions.
