For this car, the intake air pressure sensor is in the intake pipe, and it is installed near the intake throttle valve.
The automobile oxygen sensor is an electronic injection engine. The key feedback sensor in the control system is a key component for controlling automobile exhaust emissions, reducing automobile environmental pollution, and improving automobile engine fuel combustion quality. There are two types of oxygen sensors, zirconium dioxide and titanium dioxide.

"Particle Sensor and Sensing Method" is a patent applied by Royal Philips Co., Ltd. on May 31, 2016. The patent publication number is CN107709965B. The patent publication date As of June 8, 2021, the inventor is J. Marra.
A particle sensor includes an electrostatic particle charging section and a parallel plate particle settling section, and a sensor for detecting the deposited particles to generate a sensor signal. The pre-filter is placed upstream of the particle powering section. The prefilter characteristic is such that the sensor signal in response to entrained particles that are not filtered out by the prefilter is related by the calibration constant S to the apparent particle number concentration Napp of the particles entering the particle sensor compared to what would exist in the absence of the prefilter. This calibration constant S is less dependent on dp,av than the dependence of the counted mean particle diameter dp,av of the particles entering the particle sensor. Thus, the dependence of the sensor signal resulting from particle deposition in the sedimentation section of the parallel plates on the particle size distribution, which dependence is caused by incomplete particle deposition in the sedimentation section, is at least partially compensated by the pre-filter, which Prefilters have an appropriate dependence of their filtration function on particle size.
