What are the reasons for a sudden loss of power in a car?

The fault is often caused by cracks or welds breaking at the root of the fuel pipe in the fuel tank, allowing a large amount of air to enter the fuel system. This results in an overly lean air-fuel mixture or even prevents the engine from drawing fuel, leading to a loss of acceleration. Below are the relevant details: 1. Fuel Tank: A container in a car used to store fuel, specifically designed to hold hydraulic oil or fluid in a hydraulic system. Fuel tanks can be categorized into open and closed types. The tank must have sufficient capacity; the suction and return pipes should extend below the minimum liquid level to prevent air intake and splashing that creates bubbles. The distance between the suction and return pipes should be as far apart as possible, with a partition installed between them. To maintain oil cleanliness, the tank should have a sealed cover with an air filter. The bottom of the tank should be at least 150mm above the ground. Proper anti-corrosion treatment for the inner surface of the tank is essential. 2. Function: In a hydraulic system, the fuel tank not only stores oil but also serves to dissipate heat, separate air bubbles from the oil, and allow impurities to settle.
As a seasoned driver with years of experience, my first thought in this situation is a fuel system issue. It could be a faulty fuel pump, a clogged filter, or injector problems—if fuel isn't reaching the engine, acceleration will suffer. Once, my fuel pump suddenly failed on the highway, and the car immediately lost power. Electronic components like a malfunctioning throttle sensor, dirty sensors, or loose wiring can also affect throttle response. The engine can't run without fuel, so the safest move when suddenly losing power is to immediately turn on hazard lights and pull over, then briefly check wiring near the fuel tank. I make it a habit to change the filter every 5,000 km and check the fuel pressure gauge during maintenance to prevent major issues, especially with older cars—extra vigilance helps avoid surprises.
