Final answer:
Carburetor heat reduces engine power by decreasing the density of the fuel-air mixture and leading to a leaner mixture. This decreased density leads to a leaner fuel-air mixture and subsequently reduces the engine power output. In other words, when carburetor heat is applied, less fuel is burned, resulting in a decrease in engine power.
Step-by-step explanation:
When carburetor heat is applied in an engine, it actually reduces the engine power. The reason for this is that the application of carburetor heat increases the temperature of the incoming air-fuel mixture, which decreases its density. This decreased density leads to a leaner fuel-air mixture and subsequently reduces the engine power output. In other words, when carburetor heat is applied, less fuel is burned, resulting in a decrease in engine power.
