What is the original brand of Wuling Hongguang intake pressure sensor?

The intake pressure sensor is a Bosch brand. Bosch is one of the largest manufacturers of sensors and electronic systems for automobiles and other platforms in the world. It reveals a new system called BoschRidecare. Ridecare is a separate sensor box that can detect vehicle damage or smoke inside the vehicle. The goal of the system is to help maintain the road performance of the car and ensure that the car is clean and smoke-free.

Working principle of pressure sensor

The intake pressure sensor detects the absolute pressure of the intake manifold behind the throttle. It detects the change of absolute pressure in the manifold according to the engine speed and load, and then converts it into signal voltage and sends it to the engine control unit ECU. The ECU controls the basic fuel injection quantity according to the signal voltage.

There are many kinds of intake pressure sensors, such as piezoresistive capacitors. Piezoresistive sensor is widely used in D-type injection system because of its advantages of fast response time, high detection accuracy, small size and flexible installation. The intake pressure sensor obtains the air density by measuring the absolute pressure in the intake pipe, and calculates the intake air volume according to the engine speed.
