WebbLambda = amount of air supplied ÷ theoretical air requirement . Lambda=1 . This means that the amount of air supplied to the engine corresponds to the theoretical amount of air required (stoichiometric air-fuel ratio). Lambda<1 . This means air deficiency, or a rich mixture, and increased power. Lambda>1 WebbLambda is used to express the air ratio between the theoretical air requirement and the actual air flow supplied: λ = supplied air flow : theoretical air flow = 14.7 kg : 14.7 kg = 1. The lambda sensor principle is based on an oxygen comparison measurement.
