Description : Discuss the drawbacks of carbureted SI engine on the base of, Air-fuel ratio, fuel consumption, power output, emission.
Last Answer : 1) Air-fuel ratio: - As in SI engine Air-fuel ratio varies from 8:1 to 18.5:1 i.e. from 8 kg of air/kg of fuel to 18.5 kg of air/kg of fuel. Richer or leaner air-fuel ratio limit causes the engine to ... 8 kg of air/kg of fuel to 18.5 kg of air/kg of fuel. So emission is more in SI engine.
