What are the names, working principles, functions and installation positions of various sensors on automobile engines?

1, air flowmeter, function: detect the amount of inhaled air and convert the detection result into an electrical signal. Installation position: between air filter and throttle.

2. The throttle position sensor, whose function is to convert the throttle opening into an electrical signal for output, so that the microcomputer can control the fuel injection quantity. Installation position: on the throttle body.

3. Oxygen sensor, function: detect the oxygen concentration in the exhaust gas and control the air-fuel ratio. Installation location: inside the exhaust pipe

Water temperature sensor, function: detect the temperature of coolant and correct the air-fuel ratio. Installation position: cooling water jacket

5. Knock sensor, function: to detect whether the engine has deflagration. Installation position: on the cylinder block

6. Crankshaft position sensor for ignition timing control. Installation location: front end of crankshaft, front end of camshaft and distributor. Different models have different installation positions.

7. Intake air temperature and pressure sensor. Function: detect intake air temperature and pressure. Installation position: behind the throttle body. I hope to get your adoption. Thank you.
