Sensors used in Engine compartment of Cars

Various sensors used in engine compartment in cars and its functions.

3. What is a Sensor?

4. Sensing And Monitoring The primary function of automobile sensors is data gathering and transmission to the electronic control system ( ECS ) These car sensors and ECS translate the physical and chemical change variables into electric signals.

5. ECU( Electronic Control Unit) An electronic control unit, also called an electronic control module, is a device which controls multiple systems of an internal combustion engine in a single unit.

6. TYPES OF SENSORS OXYGEN SENSOR MASS AIR FLOW(MAF) SENSOR ENGINE OIL LEVEL SENSOR PRESSURE ENGINE OIL SENSOR COOLANT TEMPERATURE SENSOR COOLANT LEVEL SENSOR AIR INTAKE TEMPERATURE SENSOR MANIFOLD ABSOLUTE PRESSURE(MAP) SENSOR BOOST PRESSURE SENSOR ENGINE KNOCK SENSOR AIRBAG SENSOR Nox SENSOR

7. OXYGEN SENSOR Oxygen sensors, often known as O2 sensors, monitor the oxygen content of vehicle exhaust systems. The ideal ratio of air to fuel for an internal combustion engine is 14.7:1. This means that to burn one gram of fuel, 14.7 grams of air must be present in the combustion chamber.

8. Mass Air Flow (MAF) Sensor The mass airflow sensor is a part of the car’s air intake system that measures the volume of air entering the intake. It is usually located in between the intake filter and the intake manifold.

9. Engine Oil Level Sensor Maintaining an engine’s oil level is important for the smooth functioning of the engine. If not checked properly, then there could be wear and tear of the IC engine. This sensor, is often found on the side of the oil pan.

10. Pressure Engine Oil Sensor The engine oil pressure sensor is usually located at the base of the cylinder head.  Ensure engine oil gets into the engine’s nooks and corners, enabling flawless functioning and prolonging engine life by preventing metal-on-metal contact .

11. Coolant Temperature Sensor This sensor ensures the engine is operating at its optimal temperature for optimal efficiency. These system circulate coolants to take the heat out of the engine and then recool the coolant by passing it via the radiator. This continues in an endless cycle as long as the engine is operating .

12. Coolant Level Sensor As was previously discussed, coolants are pushed through the engine to prevent overheating. When the coolant level drops below a preset threshold, the coolant level sensor, which is located inside the expansion tank or at the bottom of the radiator, triggers a warning light.

13. Air Intake Temperature Sensor The temperature of the air entering the engine will affect how well the car performs. The air intake temperature sensor is between the intake filter and the intake manifold.

14. Manifold Absolute Pressure (MAP) Sensor It calculates the difference in pressure inside and outside the engine manifold to ensure that the engine always gets adequate fuel, regardless of pressure differences outside the engine.

15. Boost Pressure Sensor Boost pressure sensors are only found in cars with forced induction, particularly in turbocharged or supercharged vehicles. These sensors, which are frequently located inside the intake pipes of engines.

16. Air Bag Sensor These sensors monitor wheel speed, brake force, and forceful impacts with objects. After receiving a signal from airbag sensors, the inflator system in your automobile injects nitrogen gas into the airbag. In the case of a side, rear, or front collision, this acts as a cushion.

17. Nox Sensor Vehicle emission control systems depend on nox sensors.  These sensors provide information to the ECU, which controls the air-fuel mixture during engine combustion. NOx sensors prevent your car’s exhaust system from being over-exhausted.
