Automotive MEMS sensors

Engine management systems

Bosch barometric pressure sensors are a key component in engine management for diesel and gasoline engines. They are designed to measure the current ambient pressure accurately and with low drift.

Atmospheric pressure is a function of height above sea level as well as of weather conditions.

Based on the sensor measurement data, the engine management system can supply the combustion engine with the optimum air-fuel mixture, irrespective of whether the vehicle is travelling along a coastal road or a road up in the mountains.

The benefit of this constant rebalancing of the mixture ratio is that it reduces fuel consumption as well as emissions of CO₂ and other pollutants.
