What are the reasons why a gasoline car cannot accelerate?
2 Answers
Fuel is too dirty, the fuel injector is clogged, or the fuel filter is clogged. The following is a related introduction to automotive gasoline: 1. Overview: Automotive gasoline is a liquid fuel refined from petroleum, mainly used for cars and motorcycles. 2. Classification: Chinese automotive gasoline is divided into unleaded and leaded types. The unleaded types have octane ratings of 90, 93, and 95 RON (Research Octane Number). The leaded types have octane ratings of 90, 93, and 97 RON. Among them, the lead content of 90-grade gasoline does not exceed 0.35g/L, while the lead content of 93-grade and 97-grade gasoline does not exceed 0.45g/L.
I've been repairing cars for over ten years and often encounter situations where gasoline cars can't accelerate properly—simply put, stepping on the gas pedal feels weak with poor power. The most common issues are problems with the fuel pump, leading to insufficient fuel supply, or clogged fuel lines where a dirty fuel filter blocks the flow of gasoline. Additionally, if the fuel injectors are clogged with carbon deposits or the air filter is full of dust, inadequate air intake results in incomplete combustion, also causing poor acceleration. Issues in the ignition system, such as aging spark plugs or faulty ignition coils, can lead to misfires, making pressing the gas pedal useless. Moreover, modern cars rely on sensors like the throttle position sensor or oxygen sensor—if these malfunction, the engine control unit can't accurately regulate fuel delivery. In such cases, I advise drivers not to panic. First, check simple components like the air filter. If that doesn’t help, head to a professional repair shop for diagnostics—don’t push through on the highway, as it’s extremely dangerous. Regular maintenance, using high-quality fuel, and inspecting the fuel system and ignition components every six months can prevent such issues in advance.
