Schematic diagram of a modern exhaust-gas treatment system for the reduction of particulates and nitrogen oxides.
Oxygen sensor
Determines the residual oxygen content in the exhaust gas – for an optimum air-fuel mixture.
Exhaust gas temperature sensor
Monitors the optimum temperature and protects the components in the exhaust system.
Differential pressure sensor
Monitors the loading status of the particulate filter and enables demand-controlled regeneration.
Nitrogen oxide sensor (NOx)
Precisely measures the nitrogen oxide content in the exhaust gas and thus supports the necessary dosing of AdBlue.
Particulate matter sensor
Measures the remaining particulate flow in the exhaust gas and monitors the function of the particulate filter.
All sensors produced are subjected to a series of stringent quality and performance tests. They are tested in various procedures under extreme conditions for e.g. durability, vibration resistance and tightness.
In its international development and manufacturing network, Bosch produces reliable quality at original equipment level: whether for series production or the independent aftermarket (IAM), many sensors are manufactured on the same production line. The high quality standards are equally carefully controlled and secured in all participating manufacturing countries.
Monitor vehicle emissions and ensure that they comply with legal regulations. Thanks to their precise measurement, they contribute to reducing environmental impact and optimizing engine performance.
Monitor various parameters such as air mass flow, temperature and pressure – for optimum performance and more efficient engine operation. The sensors help to reduce fuel consumption and emissions and improve the overall engine performance.
Are essential for the safety, comfort and reliability of modern vehicles. Tire pressure monitoring sensors, for example, monitor tire pressure and thus help to prevent accidents and increase road safety.
Are you looking for the right component, sensor or motor for your industrial application? Then the Bosch iBusiness industrial customer division is the right place for you. The international team of experienced engineers and technical experts will provide you with individual, solution- and system-oriented advice on your projects and support you in implementing exciting applications outside the automotive world.
Since 2014, all new vehicles within the EU must be equipped with tire pressure monitoring systems.
With the new generation of QUICK FIT⁺ sensors, the Tire Pressure Analyzer 400 (TPA 400) and technical support, Bosch offers a comprehensive package that makes it easier for workshops to diagnose, remove, install and program TPMS sensors.
