A lambda sensor, also referred to as an oxygen sensor, is a tool used to measure the quantity of oxygen in an engine’s exhaust fuel. This info is then used to regulate the air-fuel ratio, which is the ratio of air to gas within the engine’s combustion chamber. The lambda sensor is a vital a part of the engine administration system, because it helps to make sure that the engine is operating effectively and cleanly.
There are two primary forms of lambda sensors: narrowband and wideband. Narrowband sensors are inexpensive and are utilized in most autos. They’ll solely measure the air-fuel ratio inside a slim vary, sometimes from 14.7:1 to 16:1. Wideband sensors are dearer however can measure the air-fuel ratio over a wider vary, sometimes from 10:1 to twenty:1. They’re utilized in some high-performance autos and in autos which can be geared up with superior engine administration techniques.
