Manifold Absolute Pressure (MAP) Sensor Optimizes Fuel/Air Mixture Ratios

September 1, 2008

MOORPARK, Calif. – Kavlico, a global business unit of Custom Sensors & Technologies (CST) has released its new MAP sensor which utilizes a MEMS-based piezo-resistive (PRT) sense element. This new MAP sensor design is available in pressure ranges up to 3 Bar and has a light-weight plastic composite housing. Operating on 5 Vdc, the sensor provides a 0.5 to 4.5 Vdc analog output proportional to pressure standard with other custom outputs available.

Typically used in fuel injected engine management systems, MAP sensors provide instantaneous manifold pressure information to the engine’s electronic control unit (ECU). Air density is then calculated to determine the engine’s air mass flow rate which is then used to determine the optimum fuel flow to be delivered. By accurately metering the fuel flow, the vehicle runs more efficiently and economically, an imperative with today’s rising fuel cost.

Kavlico’s MAP sensors are high accuracy devices and have been fully temperature compensated across the entire operating range. Capable of withstanding high vibration environments, these sensors have excellent EMC performance. Small in size, the sensors can be specified with an integral temperature sensing option for increased functionality.

For high volume, OEM applications, Kavlico’s MAP sensors may be customized to suit each end-user’s application specific design criteria such as with a twist lock or fastener mount configuration.
