In 1976, Bosch started production of the lambda sensor. It paved the way for three-way catalytic converters and cleaner exhaust emissions. The lambda sensor measures the oxygen content of the exhaust gas before the gas enters the catalytic converter. The data provided by the sensor enables the electronic injection control unit to vary the composition of the air-fuel mix, thus maximizing combustion efficiency and exhaust purification by the catalytic converter.
