Dating back to the decades of late 80s and early 90s, the automotive industry was going through a revolutionary phase. Every function of the vehicle from engines to drivetrains started receiving updates with their controls given to a central processor and a series of sensors. Today, the same trend continued and took a steep height in installing sensors for everything we couldn’t even have imagined. Right from the safety to ease of use, from driving assistance to theft protection, the car sensors are simply doing wonders.
When asked for the latest sensor updates in the latest cars, the experts of the Las Vegas Mazda handed over to us a lengthy list that we felt like worth sharing.
Areas of Functionality
Engine functionalities that used to be operated with wither mechanical or electromechanical mechanisms like the carburetor, vacuum spark advance, distributor, and linkage of throttle kickdown are all now being controlled by the sensors and computers installed for the drivetrain.
Located near the stream of the exhaust system, and usually right after the catalytic convertor, we can find the oxygen sensor that is also termed as O2 sensor keeps monitoring the content of the exhaust gases to maintain the right proportion of oxygen. The oxygen sensor collects the information compared to the oxygen proportionin the ambient air and detect if the engine is running on a good fuel ratio. Depending upon the information received, the engine computer further uses this information to chalk out the fuel metering strategy along with therate of emission.
Engine Speed Sensor
The engine speed sensor is made to measure the rotational speed that the crankshaft makes in itself in the RPMs. This sensor is developed to have a Hall effect that works on the basis of a serrated diskpaired with a magnetic coil. When the crank starts spinning, a current as well a magnetic field get created around the coil, and this is the time when the disk starts disrupting the field. These disruptions will join hands to serve like a “count” to the RPMs. The engine speed sensor works to sort out the problems with cruise control, fuel and ignition problems.
Fuel Temperature Sensor
This sensor is to measure the temperature of the car fuel. This is necessary because fuel with lesser densitywork better for ignition, and relatively warmer fuel is lighter in density while fuel that is colder in temperature concentrates and grow denser that becomes harder to use for ignition. The fuel temperature sensor senses the fuel temperature and sends this information to the engine computer to take the necessary actions to heat up the fuel. The opposite is true for colder fuel. This is why adamaged fuel temp sensor shows the “check engine” light while effecting a dropin the fuel economy rates.
According to the Henderson Mazda dealership experts, more and more sensors are coming up to monitor the processing of the engine and drivetrain, but nowadays more variety of sensors are regulating the safety features in the latest cars.
