What are the causes of poor engine acceleration?

[LeCarmen]

The causes of poor engine acceleration are: 1. Air leakage in the intake system; 2. Low cylinder pressure or excessively small valve clearance; 3. Malfunctioning throttle position sensor. When poor engine acceleration occurs, the following inspections can be performed: 1. Check if the air filter is clogged and clean or replace it promptly; 2. Inspect the intake system for any air leaks; 3. Perform fault self-diagnosis to check for any fault codes. An engine is a machine capable of converting other forms of energy into mechanical energy, determining the vehicle's power, fuel economy, stability, and environmental performance. Automotive engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid power systems.
