If we drive with a dirty air filter...
A)The engine will produce more polluting emissions to the air.Correct
B)The engine will consume less fuel and work better.
C)The air/gasoline mixture will be lean.
A dirty air filter (dust, insects, impurities, ...) prevents the engine from receiving all the air it needs for optimal performance, increasing fuel consumption and pollution.
For this reason it is important to check it periodically, taking into account that it gets dirtier in summer than in winter.
The air/gasoline mixture will be rich, since it will have an excess of gasoline due to not being able to collect all the air the engine needs because of having a dirty or obstructed air filter.
