exhaust gas sensor.

other concepts in the future, the installation space for exhaust gas sensors will be increasingly narrower. In addition, the sensors are exposed to increasingly higher temperatures. Have to be smaller, versatile and, above all, faster: These will be the salient features of future developments. For compliance of emissions that will harden permanently will require high quality materials that allow higher temperatures, even at hotspots. Application


  • Engine Management Function
  • Measuring the concentration of oxygen in the exhaust gases. This magnitude of measurement is the basis for the three-way catalyst (gasoline engine) and Lambda control function (diesel).
  • Mount Exhaust Unit

Bosch Lambda probes into series production and its predictive system braking

Writing

El sistema predictivo de frenada de emergencia pasará pronto por  las instalaciones del taller A new electronic which will soon appear on the workshop facilities. Bosch announced that it has begun mass production of its predictive system of emergency braking, which will form part of the package of options " pre-sense" in the new Audi A8.

is a system that helps drivers brake more efficiently to the risk of rear-end collision. It is based on the ESP car, two sensors long-range radar LRR3 part of the intelligent speed ACC and complementary a video camera.

sensors are located at both ends of bumpers front and the camera in the windshield , at the height of the mirror. Bosch says it has been the interaction of data collected by sensors and camera, so that they can be identified more precisely what happens on the road while driving.

Thus, if the system detects an obstacle , brakes are prepared for possible emergency braking. The pills approach the brake discs to get a better reaction if the driver brakes. Failure to take action, an acoustic warning , followed by a brief partial automatic braking. If you can not avoid the collision, the system stops half a second before the collision with the greatest slowdown possible.
