What are the reasons for the decrease in engine power of the BMW X6?

"The reasons for the decrease in engine power of the BMW X6 include carbon buildup issues, fuel system problems, intake system problems, and engine overheating. Carbon buildup issues, including cylinder carbon buildup, throttle carbon buildup, spark plug carbon buildup, and intake carbon buildup, are directly related to the engine's power output. Fuel system problems, such as using incompatible fuel grades, can lead to a decrease in the car's power output and reduced performance. Alternatively, a blocked fuel tank vent can cause a lean air-fuel mixture, resulting in weak engine acceleration. Intake system problems, such as insufficient air intake, can cause an overly rich air-fuel mixture, leading to a decrease in engine power. For vehicles equipped with turbochargers, a malfunction in the turbocharging system can also result in reduced engine power or performance. Engine overheating, caused by insufficient engine oil, insufficient engine coolant, or malfunctioning engine cooling systems, can increase the engine's load and lead to poor heat dissipation. Solutions for decreased engine power: Promptly clean the engine to remove carbon buildup; replace the air filter or clean the three-way catalytic converter; remove air from the fuel system and drain all fuel from the fuel tank and fuel filter, then refill with the correct fuel grade and quality at a 4:1 ratio, ensuring all air is purged using a hand pump and vent screw; seek professional repair services at a specialized workshop or 4S store, and avoid operating under unclear conditions to prevent further damage to the vehicle. Engine maintenance methods: Use high-quality engine oil; use qualified coolant; regularly clean radiator scale; periodically remove carbon buildup from the car; replace the car's three filters on time; maintain reasonable engine RPM. The car engine is the device that provides power to the vehicle, determining its performance, fuel efficiency, stability, and environmental friendliness. The engine consists of components such as the crankshaft and connecting rod mechanism, valve train, fuel supply system, cooling system, lubrication system, ignition system, and starting system."
I've noticed that the BMW X6 tends to lose engine power after prolonged use, commonly due to carbon buildup issues. Driving too slowly in the city causes incomplete fuel combustion, leading to clogging in the fuel injectors and throttle body. I've personally seen a friend's X6 with this problem - it was restored after a cleaning. Another issue could be aging fuel system components, like the fuel filter or high-pressure fuel pump failing, which naturally reduces power output. It's recommended to perform regular engine cleaning, ideally every 20,000 kilometers, as it saves money and ensures safety. The air system shouldn't be overlooked either - a dirty air filter restricts airflow to the engine, significantly impacting performance. These might seem like minor daily maintenance items, but neglecting them could lead to more severe engine wear.
