Press Release Body = For many years manufacturers sought a method to extend the range of exhaust gas sensors to cover the entire range of engine operations. In the early 1990\'s NTK patented the pump-cell sensor now known as WBO2 or UEGO sensor. The first ones (NTK L1H1) were used on lean-burn Honda engines because engine operation could not be controlled by a NBO2 signal on the lean side of 14.7 (see curve). It was quickly discovered that these sensors also work in a rich gas environment. Many modern turbo engines require tight control over the air/fuel ratio to keep emissions at minimum but nevertheless produce enough power. These applications keep the engines just shy of the onset of knock. The Bosch LSU4 series sensors were designed with that application in mind and are widely used by OEM\'s in turbo engines.
