Bosch has added new exhaust-gas temperature sensors and nitrogen-oxide sensors for most of the vehicles on the European market. The ever growing Bosch workshop range also features lambda sensors, particle sensors and differential-pressure sensors.
Combining these new sensors with the Denoxtronic exhaust-gas treatment system, workshops are provided with a comprehensive range of the exhaust-gas treatment components featuring OE quality.
Reliable analysis of the exhaust-gas composition is the basis for efficient exhaust-gas treatment. For this purpose, modern cars and commercial vehicles are equipped with different sensors installed into the exhaust duct. All of these sensors are integrated into the on-board diagnostic system and can easily be identified and checked using a diagnostic tester such as, for instance, a Bosch KTS in cause of any faults. If defective, Bosch sensors can be replaced both easily and quickly.
More and more diesel cars and a growing number of light and heavy commercial vehicles are equipped with nitrogen-oxide sensors. By means of a particularly resilient and heat-resistant ceramic sensor element, these sensors measure the amount of nitrogen oxide (NOx) downstream of the SCR catalytic converter.
Some engine types include a second nitrogen-oxide sensor upstream of the catalytic converter. These sensors control the amount of urea (AdBlue) injected into catalytic converter for the selective catalytic reduction (SCR) in order to reduce the NOx emissions. In addition, they also monitor the SCR components.
As SCR technology is used more frequently, nitrogen-oxide sensors are also of increasing importance for the aftermarket and workshop business. The current Bosch range comprises 24 part numbers including the matching sensors for several vehicles. And yet, the range is continuously expanded.
Exhaust-gas temperature sensors can be installed at different locations within the exhaust duct of diesel and gasoline engines. They measure the temperature of exhaust gases and send an electric voltage signal to the engine control unit. Used in diesel engines, exhaust-gas temperature sensors monitor the temperature of the particle filter. Therefore, they significantly contribute to compliance with emission limit values and fuel efficiency.
Used in gasoline engines, exhaust-gas temperature sensors are used to protect critical components such as catalytic converters and turbochargers. Since July this year, the Bosch aftermarket range for workshops comprises some 90 part numbers covering most of the vehicles of European car makers.
The Denoxtronic exhaust-gas treatment system is also of increasing importance. Increasingly used in diesel-powered vehicles, it generates additional potentials for automotive workshops. This system injects a watery urea solution (known as AdBlue) into the exhaust duct. In combination with the SCR catalytic converter, this allows turning harmful nitrogen oxides (NOx) into water and nitrogen. As Denoxtronic system developer, Bosch provides comprehensive solutions for workshops – reaching from diagnoses and spare parts through to repairs and technical trainings.
