Integrated Pressure Sensor IC for Manifold Air Pressure Measurement Applications

The manifold air pressure (MAP) is an important parameter to compute the airfuel ratio provided to the engine for lower emission due to better combustion and increased efficiency. For cost sensitive engine systems a MAP sensor shows the potential to complement or even substitute mass air flow (MAF) sensors. In addition manifold pressure data can be used to compute diagnostics of leakages and malfunctions of the exhaust gas recirculation valve. In automotive applications where high production volumes are common there is substantial interest in precision, low-cost and fully integrated sensors. In this context products of the developed MAP sensor family KP21x are the optimum solution for aspirated or turbo diesel and gasoline engines management systems.
