Why Does the Car Engine Sound Louder in Hot Weather?
1 Answers
Here are the specific reasons why the car engine sounds louder in hot weather: Poor Acceleration Performance: When pressing the accelerator, you may notice poor acceleration, lack of power, and a hysterical sound from the engine. This is most likely to occur when the engine is hot, cold, or low on oil. Dirty Gasoline: Issues such as air filter, spark plugs, ignition wires, fuel, fuel filter, carburetor, or fuel pump problems. Check if the air filter is dirty, if the spark plugs are old and need replacement, if the ignition coil is faulty, or if the gasoline is contaminated. While driving, acceleration may seem normal, and ignition might appear fine, but when maintaining a constant speed, you might notice that the engine RPM is too high while the speed doesn't increase accordingly. Try checking the coolant, oil pressure (too high or too low), the oil pressure gauge, or the ignition timing settings, as these could also cause such symptoms. Other possible causes include internal engine issues, such as a clogged EGR valve.
