been 40 years since Bosch lambda sensors have been controlling exhaust in
vehicles. Bosch parts range provides lambda sensors in original-equipment
quality for almost any vehicle. Basically, Lambda sensors are smart controllers
inside the exhaust gas system. What they do is that they measure the
composition of the engine exhaust gases. This technology first allowed exact
dosing of the amount of fuel injected and thus highly efficient and clean
engine operation. But there is even more. In gasoline engines, for instance,
the fuel-saving overrun cut-off wouldn't be possible without modern lambda
sensors. And neither would modern exhaust gas treatment in diesel engines.
have passed since Bosch first started the series production of this invention.
These days, the one-billionth Bosch lambda sensor left the production
facilities. “Lambda sensors are and will remain a key element to ensure clean
and efficient operation of combustion engines,” Dr. Uwe Thomas, chairman of the
Bosch Automotive Aftermarket business division, said.
production figures at Bosch also clearly show the significant increase in
demand throughout the last 40 years. It took 32 years – from 1976 to 2008 – to
reach the production record of 500 million pieces, but only eight years – from
2008 to 2016 – to double the production figures to 1 billion sensors.
So when did
the story start? It was in 1976 when the Volvo 240/260-series became the first
passenger car equipped with a Bosch lambda sensor that was standard for the US
market. Already back then, the emission regulations in the USA were relatively
stringent. At the same time, the Bosch sensor gave proof of the performance
modern engine technology can provide. Often, the emission values were even much
lower than the limits allowed, thanks to accurate lambda control. By now,
lambda sensors have become an integral part of modern cars.
technical reasons, more and more gasoline-powered vehicles use two lambda
sensors per exhaust gas system. But also modern diesel vehicles are hard to
imagine without any lambda sensor. This trend will continue as the ever more
stringent statutory emission limits for newly registered gasoline and diesel
vehicles can only be achieved by means of a highly efficient exhaust gas
OE supplier, Bosch also provides a spare parts range for automotive workshops
including the matching lambda sensor for almost any vehicle equipped with a
gasoline or diesel engine. This makes Bosch the worldwide leader of the
automotive aftermarket – with a market coverage of 85 percent in Europe alone.
The product range includes hundreds of versions on stock that are thus quickly
In case of
a defective lambda sensor, car drivers should have it replaced as soon as
possible. Without correctly measured values provided by the sensor, fuel
combustion loses its effectiveness and the fuel consumption increases. An
On-Board-Diagnosis (OBD) test at the workshop can provide reliably information
on whether a lambda sensor needs to be replaced or not. By means of the
KTS-series testers and latest emission testers, Bosch provides state-of-the-art
diagnostic equipment allowing a quick and reliable evaluation of a lambda
sensor's current condition. In most cases, workshops will find just the right
lambda sensor in OE quality within the Bosch spare parts range including more
than 1 200 part numbers solely for lambda sensors. As a competent partner for
workshops, Bosch provides diagnostic equipment, parts and services from a
