At present, all the cars manufactured by the large automakers are even equipped with dozens of sensors capable of warning of any irregular operation or a possible fault in the door.
In some models, their oriented control modules can have more than 200 sensors.
And it is that these devices in a car, adIn addition to monitoring various areas, they send this information to the engine control unit (ECM) which automatically makes the necessary adjustments required by the unit to operate in optimal conditions in terms of temperature, the cooling system, the engine, the oil pressure, emission levels, vehicle speed and many other aspects.
variety of sensors
Located inside the combustion chamber, the air flow sensor is in charge of measuring the volume and density of this element that enters the engine for optimal performance, so if it fails it can cause fuel consumption to increase.
For its part, the engine knock sensor monitors the ignition process of the air-fuel mixture before the spark plugs produce the necessary spark to make this possible.
In this sense, An anomaly in its performance can reduce the efficiency of the engine and even damage various components of it.
With respect, the engine speed sensor sends the appropriate information so that the ECU calculates the exact time to perform the fuel injection and activate the spark plugs.
Howeverthe camshaft position sensor is responsible for controlling the timing of this component until the air enters the cylinder and the burned gases leave at the right time.
As far as the engine revolutions are concerned, the one in charge of monitoring that they are adequate is the voltage sensor, but if this information is not issued, it can cause a decompensation of the heart of the vehicle.
No less important is the work carried out by the fuel temperature sensor, since a failure in its performance would make it impossible to detect if the fuel is cold at the moment when it tries to burn, which would take longer, or if it is hot and ends up burning. burn too fast.
In both cases, this implies a greater or lesser fuel consumption.
In any case, through these examples you can get a general idea of the relevance of sensors in today’s vehicles.
