Product Brief
KP21x/MAP
Integrated Pressure Sensor IC
for Manifold Air Pressure Measurement
Applications
Application
The manifold air pressure (MAP) is an important parameter to compute the air-
fuel ratio provided to the engine for lower emission due to better combustion
and increased efficiency. For cost sensitive engine systems a MAP sensor show
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.
