What Causes Engine Power Loss When Accelerating at High Temperatures?

[SanIker]

Engine power loss when accelerating at high temperatures can be attributed to the following reasons: Fuel system faults: A clogged or waterlogged air filter reduces air intake, leading to an overly rich air-fuel mixture, incomplete combustion, and poor acceleration. In this case, the exhaust pipe emits heavy black smoke. Cracks in fuel lines or loose/leaking connections, along with insufficient fuel pump pressure, result in poor fuel delivery and affect acceleration performance. Poor atomization or clogging of fuel injectors causes cylinders to misfire or stop working, impacting acceleration. The exhaust pipe may emit black smoke. Fuel quality is another factor. If the fuel contains excessive water, the exhaust pipe will emit white smoke. Electrical faults: Malfunctioning air flow meters reduce air intake, causing the air-fuel mixture to become overly rich or lean, affecting acceleration. Damaged spark plugs in individual cylinders (i.e., cylinder misfire) also impair acceleration. Additionally, issues like leaking ignition wires can contribute. Mechanical faults: Wear and tear of engine valves, cylinder liners, pistons, or piston rings result in insufficient cylinder compression. Excessive intake valve clearance or insufficient exhaust valve clearance can also cause problems.
