Abstract
The precise, fast and wide range measurement of exhaust gas oxygen concentration is a key element to the development of low emissions combustion engines. This is true to Gasoline Direct Inject and Common Rail Diesel engines, but even standard Multi Port Injection ( MPI ) engines benefit from a better lambda control ( SULEV applications ).
The proliferation of linear oxygen sensors has up to now been hindered by a lack of compatibility of sensors / interface electronics among different suppliers, keeping the cost high.
A newly developed interface electronics brings down that barrier, giving the car manufacturers the freedom of choice among different sensor suppliers, reducing the effort mainly to software adaptation.
The sensor interface is a self contained integrated circuit with minimum external components for additional sensor adaptation. It has built in diagnostics, full sensor protection, and is controlled by an external micro controller.
