What Causes Poor Acceleration When the Car Air Conditioner is On?
1 Answers
When the car air conditioner is on, the engine experiences a higher load, especially during hot summer days. This leads to an increase in fuel vapor and a relative decrease in fuel pressure within the fuel system. Additionally, a clogged fuel filter can result in insufficient fuel supply, causing poor acceleration. Below are the relevant details: 1. Causes of poor acceleration in cars: The feeling of sluggishness in a car is primarily due to the engine not receiving enough fuel during uphill driving, which reduces combustion efficiency and results in insufficient horsepower. 2. Reasons for slow acceleration: Besides fuel, the engine also requires air. If components like the air filter or throttle are clogged or malfunctioning, leading to insufficient air intake, the car may experience poor acceleration and slow speed increase.
