What are the reasons for a vehicle's inability to accelerate?
2 Answers
There are several reasons why a car cannot accelerate, including fuel supply system failure and damaged spark plugs or high-voltage wires. Below is a detailed explanation of the reasons for a car's inability to accelerate: Fuel supply system failure: The primary source of a car's acceleration power is the engine, which operates on fuel. When there is an issue with the fuel supply system, the vehicle cannot accelerate properly during rapid acceleration. Damaged spark plugs and high-voltage wires: Spark plugs and high-voltage wires are critical components of a car. The main function of spark plugs is to generate sparks to ignite the air-fuel mixture in the cylinders, thereby increasing the vehicle's speed. If there is a problem with the spark plugs or high-voltage wires, the car will not be able to accelerate during rapid acceleration.
I remember last year my car suddenly had trouble accelerating, the throttle response was sluggish, and it felt really hard to drive. I rushed to get it repaired, and the mechanic found that the air filter was completely clogged, affecting the engine's air intake. The spark plugs also needed replacement, as they had been in service for over 30,000 kilometers. The fuel filter was also blocked, causing insufficient fuel supply. If there's an automatic transmission malfunction or an issue with the gear lever, it can also lead to a lack of power. It's recommended to perform regular maintenance, change filters and oil periodically, and not delay until problems arise like I did. Acceleration issues can also stem from engine carbon buildup, which requires regular cleaning.
