@ericalzablon: When an engine presents high fuel consumption, outside of the mileage indicated by the manufacturer, it means that the fuel mixture regulation strategy (closed loop control) is disrupted. The ECU uses information from MAF or MAP, ECT, TPS/APP, and oxygen sensor to calculate the actual engine load and precisely adjust the pulse width of the injectors, keeping the mixture close to λ = 1. When this control fails, the engine enters a rich mixture, injecting more fuel than necessary. The excess is not burned and generates black smoke, coblackto by hollín, which deposits on spark plugs and oxygen sensor, altering their readings and causing the ECU to continue enriching the mixture incorrectly. To correct this condition, it is necessary to specifically regulate: – The actual amount of air entering the engine, checking MAF/MAP, leaks, and clean acceleration body. – The amount of fuel injected, checking rail pressure, injector condition, and fuel corrections (STFT and LTFT). – The feedback from the oxygen sensor or A/F, ensuring it responds correctly and is not contaminated by hollín. – The ECU's learning, performing relearnings or resets when the system requires it. The direct effects of not correctly regulating this mixture are: loss of power, unstable acceleration, fuel smell, catalytic converter damage, oil dilution, increased HC and CO emissions, and Check Engine light. As explained in Auto Avance, high consumption is not corrected by "adjusting the eye," but by restoring the real control of air, fuel, and electronic feedback. #fyp #viral #tiktok
