What is a lambda fonction on Chevrolet Suburban?

So we begin our content page with the interest of a lambda sensor on Chevrolet Suburban , we will first see what is the purpose of this probe and then how it functions.

Role of a lambda sensor on Chevrolet Suburban

First produced by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. Also called oxygen sensor on Chevrolet Suburban , its objective is to regulate the amount of oxygen in the exhaust gases, this will allow the engine to adapt the air/fuel mixture to decrease the pollution released by the motor vehicle and lower the car’s fuel consumption.

One could naively believe that this data is calculated upstream of the combustion but it is on the contrary measured at the engine outlet . With the EURO 1 standard there was just one lambda sensor needed before the catalyst, but with the arrival of more drastic standards there are now 2 lambda sensors, one before and one after the catalyst . The interest is to have more exact data by compiling the two probes. These data are sent to the ECU which will adapt the quantity of air and gasoline inserted into the engine to optimize the combustion .
