What does engine power reduction mean?
2 Answers
Engine power reduction refers to the decrease in gasoline combustion efficiency, resulting in reduced engine output power. The reasons for this reduction include: 1. Excessive carbon deposits inside the engine, leading to reduced ignition energy and decreased intake efficiency, causing idle weakness; 2. Adding incompatible fuel grades or a blocked fuel tank vent, clogged fuel filter, or partial blockage of the fuel line between the fuel tank and carburetor, which cannot meet the required fuel supply, resulting in an overly lean air-fuel mixture; 3. Long-term use of the air filter without timely cleaning causing blockage, insufficient air intake leading to an overly rich air-fuel mixture; 4. For vehicles with turbochargers, failure of the turbocharging device.
Engine power reduction means your car doesn't have the same acceleration as before when you press the gas pedal, with slower speed increase and a feeling of the car being sluggish or lacking power during acceleration. This is a common issue, usually caused by a dirty air filter blocking air intake, worn spark plugs causing poor ignition, or poor-quality gasoline leading to incomplete combustion. I've experienced it myself - after filling up with cheap gas once, my car felt like it was dragging, but it recovered after switching gas stations and replacing the air filter. If not addressed promptly, it can waste more fuel and damage engine components. I suggest you first check the air filter yourself and replace it if dirty, and inspect whether the spark plugs have severe carbon buildup. If you can't fix it, go to a repair shop immediately and let the mechanic read the fault codes with diagnostic equipment - don't keep driving to avoid major problems. Regular use of quality gasoline and periodic air filter changes can prevent this issue.
