What Causes the Engine to Sound Muffled and Have Weak Acceleration?
1 Answers
This situation occurs due to carbon buildup in the cylinders, throttle body, spark plugs, intake ducts, and other areas. Poor functioning of the exhaust gas recirculation system, as well as faults in the air flow meter, intake manifold absolute pressure sensor, and throttle position sensor, can also lead to weak engine acceleration. Below are detailed explanations regarding the engine: 1. Automobile Engine: The automobile engine is the device that provides power to the vehicle, serving as the heart of the car. It determines the vehicle's power, fuel efficiency, stability, and environmental performance. Depending on the power source, automobile engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others. 2. Advantages: Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement to output power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easier to start, and have lower manufacturing costs. Diesel engines have higher compression ratios, better thermal efficiency, and superior fuel economy and emission performance compared to gasoline engines.
