A vehicle that is not well maintained poses a risk not only for road safety but also for the environment. This is because the malfunction of certain systems or parts of a car can lead to a considerable increase in fuel consumption, as well as the emission of polluting gases.
From the Spanish Association of Collaborating Entities of the Administration in the Technical Inspection of Vehicles AECA-ITV explain some of the mechanical conditions that can affect the performance of a car.
Thus, some of the parts or systems whose incorrect operation can lead to an increase in vehicle fuel consumption are, first of all, dirty air filters. Not having them in good condition can limit the amount of air that flows into the car’s engine, making it work harder. This fact can increase fuel consumption by up to 10% vehicle.
Bad plugs. Since these parts are responsible for providing the spark for combustion to take place, if they are not in good condition, correct consumption or control of gas emissions cannot be guaranteed.
Or also the battery in bad condition. And it is that if this part does not work correctly, not enough energy will reach the spark plugs, so fuel consumption increases.
Likewise, a incorrect tire pressure It can be assumed that fuel consumption increases by 5%, since the contact surface with the ground increases.
But perhaps one of the most important aspects when it comes to improving the efficiency of a car is the way it is driven. According to the DGT, with good driving habits, vehicle emissions can be reduced by 15% and, in addition, lower fuel consumption.
