Map Sensor

A CNG (Compressed Natural Gas) MAP sensor is a specialized variant of the Manifold Absolute Pressure sensor designed for vehicles running on CNG fuel systems. Its primary function is to measure the pressure in the intake manifold and monitor the flow of CNG into the combustion chamber, ensuring precise control of the air-fuel ratio. Unlike gasoline MAP sensors, the CNG MAP sensor is calibrated to handle the unique properties of natural gas, such as its lower energy density and different combustion characteristics. The data collected by the CNG MAP sensor is sent to the Engine Control Unit (ECU), which uses it to regulate the injection of CNG, ensuring optimal combustion efficiency, reduced emissions, and enhanced fuel economy. Additionally, the sensor helps monitor the switch between CNG and gasoline in bi-fuel vehicles, maintaining seamless operation. If the CNG MAP sensor fails or provides inaccurate readings, it can lead to issues like misfires, reduced power, poor mileage, and increased emissions. The sensors environment in CNG systems often exposes it to higher pressures and varying temperatures, requiring robust design and periodic maintenance. Advanced CNG MAP sensors are equipped to withstand these conditions while ensuring precise and reliable measurements, playing a crucial role in achieving the eco-friendly benefits and performance efficiency that make CNG a popular alternative fuel choice.
