Explanation:
Idling is the correct answer of the question
Answer:
A lean air-fuel mixture is required for cruising.
Explanation:
The air-fuel ratio is the ratio of the mass of air to the mass of fuel injected in a single whole cycle in an IC engine. The stoichiometric air-fuel ratio for Gasoline engines is 14.7:1. Stoichiometric approach that each one of the oxygen withinside the gas is used to burn absolutely to provide carbon dioxide and water as merchandise ie, there may be no extra oxygen left withinside the air popping out of the exhaust of the engine.
A lean mixture/ lean burn could suggest that we're presenting the engine with a better than stoichiometric air-gas ratio. In different words, we're presenting the engine with extra oxygen to burn a required amount of gas in order that there may be a few leftover oxygens withinside the exhaust even after the whole combustion of the gas.
The metric maximum typically utilized by engineers to measure/constitute the air-fuel ratio is the Equivalence Ratio that's described because the ratio of the fuel-air ratio used presently to the stoichiometric fuel-air ratio.
