What is the reason for the high fuel consumption of the ninth-generation Accord?
2 Answers
The high fuel consumption of the ninth-generation Accord is caused by excessive carbon deposits in the engine or the spark plugs not being replaced for a long time. The specific reasons are as follows: Spark plugs not replaced: Some vehicles have been driven for hundreds of thousands of kilometers without replacing the spark plugs. Although they can still be used, the insufficient ignition energy will affect the ignition timing, causing it to miss the optimal ignition time, which will result in partial power loss. At the same time, it will also lead to incomplete combustion, further increasing fuel consumption. Therefore, the spark plugs need to be replaced. Excessive carbon deposits in the vehicle: Carbon deposits can accumulate in the throttle valve, fuel injector, intake manifold, and piston top. Excessive carbon deposits in any of these areas will affect the combustion process, leading to incomplete combustion and increased fuel consumption. Therefore, it is necessary to clean the carbon deposits in the vehicle.
Recently, when I took my ninth-generation Accord to refuel, my wallet felt much lighter! The fuel consumption is particularly high during cold starts. After consulting a friend at the repair shop, I learned that older cars are especially prone to carbon buildup, particularly when the throttle body and fuel injectors get clogged. This causes uneven fuel spray, leading to unnecessary waste. Additionally, components like the oxygen sensor can become sluggish over time, causing the engine to inefficiently inject more fuel. A clogged air filter makes things even worse—the engine struggles to breathe and ends up guzzling more fuel. My car started consuming more fuel after hitting 80,000 kilometers. I suggest you also focus on checking these areas; replacing the air filter might show immediate improvements.
