Engine Management

Engine management has made tremendous advances in the last decade with respect to efficiency improvements with the advancement and adoption of technologies such as Dual Overhead Camshaft (DOHC) engine configurations, Variable Valve Timing (VVT) engines, and stop-start engines. The automotive industry’s continual push for fuel-consumption and carbon dioxide emissions reductions has presented a number of technical challenges for the sensing systems required to support these platforms.  Allegro’s sensors have led the way in the market for these technologies:

• DOHC, VVT engine configurations require TPOS-Cam sensors capable of high accuracy immediately upon startup.
• Stop-start engines require a crankshaft sensor capable of detecting direction changes to allow for absolute rotational position information of the crankshaft independent of speed or temperature changes.
