The lambda sensor

Sensitive sniffers

In 1969, Bosch experts started developing a sensor for measuring exhaust gas, which established itself within a good decade following initial teething troubles. Nowadays, environmentally friendly combustion engines are no longer conceivable without the lambda sensor, which went into production in 1976. This Bosch innovation was the prerequisite for exhaust treatment using three-way catalytic converters. The lambda sensor measures the oxygen content in the exhaust gas upstream of the catalytic converter. This value, which constantly fluctuates dramatically according to the driving situation, is used by the electronic control of the injection system to adjust the composition of the gasoline-air mixture. The system’s accuracy ensures complete combustion, which enables the catalytic converter to optimally clean the exhaust gases. This can reduce harmful emissions by up to 90 percent.

Telecommunications — a new focus

At the start of the 1980s, Bosch ventured into telecommunications and started constructing technology for space satellites and cell phones and implementing public and private telecommunications networks. After two successful decades of this sector generating up to 25 percent of the company’s sales, unfavorable developments prompted Bosch to withdraw from several segments. The Security Systems division continued in business and remains successful to this day.
