Why does the car fail to accelerate when the air conditioning is turned on?
2 Answers
The reason why the car fails to accelerate when the air conditioning is turned on may be due to the oil pump overheating internally or in its circuit, resulting in poor working conditions, short circuits, or burnout, leading to insufficient or stopped fuel supply. It could also be caused by internal engine faults, improper internal maintenance, premature or abnormal wear, or issues with cylinder pressure and other potential faults or hazards. Relevant information about oil pressure is as follows: 1. Introduction: The residual pressure that lifts oil and gas from the bottom of the well to the wellhead through the oil pipe is called tubing pressure, or oil pressure for short. It is measured by the tubing pressure gauge, and its value is the flowing pressure minus the pressure of the oil and gas mixed liquid column in the well, friction resistance, and slippage loss. 2. Influencing factors: The oil pressure depends on the level of the flowing pressure, which in turn is related to the reservoir pressure. Therefore, the level of oil pressure reflects the energy level of the oil well.
I've experienced this before - when the AC is on, the car feels sluggish during acceleration, as if being held back. The main reason is that after the AC compressor kicks in, the engine has to divert additional power to cooling, which increases the load. If the engine itself isn't in top condition, such as having dirty spark plugs or excessive carbon buildup leading to low ignition efficiency, the added burden from the AC will make the power deficiency more noticeable. Also, if the air filter is clogged and airflow is restricted, it can cause incomplete fuel combustion resulting in poor acceleration. I remember last time with my own car, it was the same issue - after inspection, we found the fuel pump wasn't delivering stable pressure, and couldn't keep up when the AC was running. I'd suggest paying more attention to spark plug and air filter maintenance during regular servicing, and replacing the fuel filter periodically to prevent compounding issues. Using AC in summer is inevitable, so catching these minor problems early can save a lot of hassle.
