What are the sensors on the engine?

Engine sensors include: air flow sensor, throttle position sensor, accelerator pedal position sensor, intake air temperature sensor, coolant temperature sensor, camshaft position sensor, crankshaft position sensor, oxygen sensor, and knock sensor. The function of the engine is to convert the heat energy of gasoline or diesel into mechanical energy by burning and expanding the gas in a sealed cylinder, thereby pushing the piston to perform work. Engine maintenance methods include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning the water tank scale; 4. Regularly cleaning engine carbon deposits; 5. Regularly replacing the three filters of the car; 6. Maintaining a reasonable engine speed.
Speaking of engine sensors, I'm truly fascinated. There are numerous common sensors on an engine, such as the crankshaft position sensor which monitors engine speed and ignition timing, the camshaft position sensor that synchronizes fuel injection and valve control to ensure smooth operation, the oxygen sensor checking exhaust oxygen levels to help reduce pollution and save fuel, the mass airflow sensor measuring intake air volume to control the fuel mixture ratio, the throttle position sensor tracking throttle opening to optimize response speed, and the coolant temperature sensor preventing overheating to maintain engine cooling efficiency. The manifold absolute pressure sensor manages pressure in turbocharged systems to enhance power, the knock sensor detects vibrations during rapid acceleration to avoid engine damage, and the intake air temperature sensor compensates for air density affecting combustion efficiency. Last year, a sensor failure in my car caused a sharp increase in fuel consumption, which made me realize how these small components play a crucial role. I recommend regular maintenance to prevent dirt buildup and extend their lifespan.
When I first started driving, I knew nothing about engine sensors, but later I learned that they're like guardian angels. Common ones include the oxygen sensor ensuring clean exhaust and environmental compliance, the coolant temperature sensor preventing the radiator from boiling and the engine from overheating, the air flow meter controlling intake for smoother running, the crankshaft position sensor managing ignition timing crucial for starting, the camshaft position sensor coordinating fuel injector actions, the knock sensor preventing detonation during hard acceleration at high speeds to protect the engine, and the manifold pressure sensor helping regulate the air-fuel mixture for power output. Simply put, these sensors help the car avoid breakdowns and unnecessary expenses. Last time, I easily fixed a minor sensor issue during maintenance.
