What Causes Engine Power Loss During Acceleration?

[SanMia]

There are several reasons for engine power loss during acceleration: 1. Severe carbon buildup: When a vehicle operates at low RPM for extended periods, carbon deposits can form and clog the fuel system, leading to acceleration difficulties. In this case, carbon cleaning is required. 2. Poor fuel quality: Using low-quality fuel can affect the gasoline filter and fuel lines, potentially causing fuel supply issues and resulting in weak acceleration. 3. Exhaust system malfunction: This is usually caused by a broken catalytic converter. A clogged exhaust pipe will reduce engine power output. 4. Clutch failure: In manual transmission vehicles, clutch slippage can cause the engine RPM to increase during acceleration without a corresponding increase in vehicle speed. 5. Engine overheating: When an engine operates under excessive load, cylinder temperatures rise sharply, weakening acceleration capability. In such cases, engine cooling measures are necessary. 6. Fuel system problems: Issues like clogged fuel injectors or a blocked fuel filter can prevent complete fuel delivery, causing insufficient power output.
