What Causes a Car to Lose Power When Accelerating with the AC On?
1 Answers
When a car loses power while accelerating with the AC on, it is primarily because the air conditioning system places a significant load on the engine. This issue is especially noticeable during hot summer months when fuel vaporization increases, leading to reduced fuel pressure within the fuel system. Additionally, a clogged fuel filter can result in insufficient fuel supply. Below are some key points regarding engine maintenance: 1. Use the appropriate lubricating oil: For gasoline engines, select SD to SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB to CD grade diesel engine oil according to mechanical load requirements, ensuring the standard meets or exceeds the manufacturer's specifications. 2. Regularly change the oil and filter: To prevent malfunctions, replace the oil periodically based on usage conditions and maintain an optimal oil level (generally up to the upper mark on the dipstick). As oil passes through the fine pores of the filter, solid particles and viscous residues accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or activate the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication areas, accelerating engine wear and worsening internal contamination.
