A rich air-fuel ratio causes HC emissions to ________.

Expert Solution & Answer

To determine

The appropriate word to fill in the blank in the statement “ A rich air-fuel causes HC emissions to _______”.

Answer to Problem 1RQ

A rich air-fuel ratio causes higher HC emissions.

Explanation of Solution

Unburned hydrocarbons are usually, vapors of gasoline that have not been burned during combustion. HC emissions illustrate that the combustion of fuel is not completed in the engine cylinder. The amount of HC depends on certain engine conditions, one of which is a rich air-fuel ratio. Whenever the mixture of air-fuel is extremely rich it causes higher HC and CO emissions.
