What are the reasons for decreased engine power?
2 Answers
The reasons for decreased engine power: 1. Excessive carbon buildup on valves and intake pipes is a relatively common cause of reduced car power. The solution is to seek professional auto repair personnel to help clean the carbon deposits and check if the spark plugs need replacement; 2. Inspect the fuel supply system for any blockages or vapor lock in the fuel lines, whether the fuel pump is functioning properly, if the carburetor float chamber fuel level meets the specified requirements, if the air filter is clogged, and if the exhaust system is obstructed; 3. Poor tire pressure is also one of the factors affecting reduced car power, especially when the tire pressure is insufficient and carrying a large number of passengers, the effect is more noticeable. Therefore, when inflating tires, ensure they are adequately filled according to the tire pressure chart indicated on the vehicle body.
I've been driving for decades, and sudden loss of engine power is quite common. The most frequent issue is fuel system problems, like a weak fuel pump or clogged fuel injectors preventing proper fuel delivery, which slows acceleration. Worn-out spark plugs can cause misfires, making the car shake. A dirty air filter also hampers performance by restricting airflow, choking the engine. Exhaust system blockages, such as a faulty catalytic converter, trap exhaust gases and reduce efficiency. Older cars often suffer from loose belts or alternator issues. It's advisable to inspect these components every six months. Replacing the air filter yourself is simple, but complex problems should be addressed early to avoid major repairs. Maintaining regular service habits ensures stable engine performance.
